The polyester in standard form with zero placeholders is
-x^6+0x^5+3x^4+-7x^3+4x^2+0x+-1
7th term -1
6th term 0x
5th term 4x^2
4th term -7x^3
3rd term 3x^4
2nd term 0x^5
1st term -x^6
Step-by-step explanation:
We want to write 4x^2-7x^3-x^6+3x^4-1 in descending order means want the exponents to being counting down.
6 is the highest exponent so lets rearrange this so that tern comes first:
-x^6+.....
5 is the highest but we are missing so now we have:
-x^6+0x^5+....
4 is the next highest and I see +3x^4 in our polynomial so that comes next:
-x^6+0x^5+3x^4+...
3 is the next highest and I see -7x^3 so that term comes next:
-x^6+0x^5+3x^4+-7x^3+....
2 is the next highest and I see +4x^2 so that term comes next:
-x^6+0x^5+3x^4+-7x^3+4x^2+...
1 is the next highest and we are missing an x term so the next term is +0x.....
-x^6+0x^5+3x^4+-7x^3+4x^2+0x+....
0 is the next highest and will be the last term we write. This is the constant tern, the term without the variable and that is -1.
-x^6+0x^5+3x^4+-7x^3+4x^2+0x+-1
Now I guess you are reading this from left to right when numbering the terms as first, second, and so on...
1st term -x^6
2nd term 0x^5
3rd term 3x^4
4th tern -7x^3
5th term 4x^2
6th term 0x
7th term -1
At Sara's new job she spent $11.52, $6.48, $5.99, $14.00, and $9.50 on lunch the first week.
In the second week, she spent $4 more in total for the 5 lunches than the first week.
second
What is the increase in the mean for the second week compared to the first? Round the
answer to the nearest penny.
Answer:
A. 0.80
Step-by-step explanation:
First, you need to find the mean of the cost of Sara's lunches the first week. The mean is the 'average,' and to find the average, add all of your terms and divide by the amount of terms.
[tex]11.52+6.48+5.99+14+9.5\\18+5.99+14+9.5\\23.99+14+9.5\\37.99+9.5\\47.49[/tex]
Sarah's total cost for the first week was $47.49. Divide by your number of terms (5) for your average daily cost.
[tex]\frac{47.49}{5} =9.498[/tex]
This can be rounded to $9.50.
For the next week, Sara spent $4 more in total than the first week. So, add $4 to your total.
[tex]47.49+4=51.49[/tex]
Now, divide $51.49 by your number of terms (5) again to find your average for the second week.
[tex]\frac{51.49}{5} =10.298[/tex]
This can be rounded to $10.30.
Find the difference.
[tex]10.30-9.50=0.80[/tex]
Sara spent $0.80 more on average.
find the coordinates of P so that P partitions the segment AB in the ratio 1:1 is A(-4,15) and B(10,11)
Answer:
The coordinates of point P are (3 , 13)
Step-by-step explanation:
* Lets explain how to solve the problem
- Point P divides the segment AB in the ratio 1 : 1
- The ratio 1 : 1 means divide the segment into two equal parts
- Then P is the mid-point of segment AB
- If (x , y) are the coordinates of the mid-point of a segments whose
endpoints are (x1 , y1) and (x2 , y2) then;
[tex]x=\frac{x_{1}+x_{2}}{2},y=\frac{y_{1}+y_{2}}{2}[/tex]
∵ The coordinates of point A is (-4 , 15)
∵ The coordinates of point B is 10 , 11)
- Let point A is (x1 , y1) , point B is (x2 , y2) and point P is (x , y)
∵ x1 = -4 , x2 = 10 and y1 = 15 , y2 = 11
∴ [tex]x=\frac{-4+10}{2}=\frac{6}{2}=3[/tex]
∴ [tex]y=\frac{15+11}{2}=\frac{26}{2}=13[/tex]
∴ The coordinates of point P are (3 , 13)

Determine if the function is a polynomial function. If the function is a polynomial function, state the degree and the leading coefficient. If the function is not a polynomial, state why. f(x)=(2x+3)^2(3x+5)^2
This is not a polynomial function because there is no leading coefficient.
This is a polynomial function of degree 4 with a leading coefficient of 36.
This is a polynomial function of degree 4 with a leading coefficient of −36.
This is not a polynomial function as the factors are not all linear.
The given function [tex]f(x)=(2x+3)^2(3x+5)^2[/tex] is a polynomial function of degree 4, with a leading coefficient of 36 determined by multiplying the squares of the leading terms of the binomials.
The function[tex]f(x)=(2x+3)^2(3x+5)^2[/tex] is indeed polynomial. To determine the degree and the leading coefficient of a polynomial, we need to expand the given expression. However, without full expansion, we can deduce the degree by adding the exponents of the individual factors since the bases are polynomials of degree 1 (2x+3 and 3x+5).
Each factor is squared, so [tex](2x+3)^2[/tex] has degree 2 and ([tex]3x+5)^2[/tex]also has degree 2. By adding these, we find that the polynomial's degree is 2+2=4. To find the leading coefficient, we consider the leading terms of each binomial which are 2x and 3x. Squaring these and then multiplying them together [tex](2x)^2 * (3x)^2 = 4x^2 * 9x^2,[/tex]we get 36 as the leading coefficient when x is raised to the 4th power. Therefore, the correct answer is: This is a polynomial function of degree 4 with a leading coefficient of 36.
What is the slope of the line shown below?
Answer:
1/6
Step-by-step explanation:
To find slope here, I'm going to use that slope is rise/run.
I'm going to start at the left dot. How much would I need to go to be on same level as the right point? Up 3.
Now that we are on the same level, how many units right would I need to travel to get to the right point? Right 18.
The slope is 3/18.
You can reduce this to 1/6.
Answer:
A. 1/6
The slope is 1/6.
Step-by-step explanation:
The slope formula is [tex]\Rightarrow\displaystyle \frac{y_2-y_1}{x_2-x_1}=\frac{rise}{run}[/tex].
[tex]y_2=6\\y_1=3\\x_2=12\\x_1=(-6)\\[/tex]
[tex]\displaystyle\frac{6-3}{12-(-6)}=\frac{3}{18}=\frac{3\div3}{18\div3}=\frac{1}{6}[/tex]
[tex]\large\textnormal{Therefore, the slope is 1/6.}[/tex]

The Amboy Kennel Club has held an annual dog show for the last 42 years. During this time he winner of "Best of Show" has been an Alaskan Malamute 21 times, a Great Pyrenees 3 times, and an Siberian Husky 18 times. Determine the empirical probability that the next winner of "Best of Show" will be a Great Pyrenees.
The empirical probability of a Great Pyrenees winning the 'Best of Show' at Amboy Kennel Club based on past performances is about 7.143%
Explanation:The subject at hand is empirical probability, which is calculated by dividing the number of times an event has happened by the total number of outcomes. In this case, the event is a Great Pyrenees winning 'Best of Show' and the total number of outcomes is the total number of dog shows.
According to the data provided, the Great Pyrenees has won 3 times out of a total of 42 dog shows. Therefore, the empirical probability can be calculated as follows:
Number of wins by Great Pyrenees = 3Total number of dog shows = 42
The empirical probability is then calculated by dividing the number of wins by Great Pyrenees by the total number of dog shows.
Therefore, the empirical probability of a Great Pyrenees winning is 3/42 = 0.07143. So, we could say that there is a 7.143% chance of a Great Pyrenees winning the 'Best of Show' in the future, based purely on historical data.

The empirical probability that the next "Best of Show" winner will be a Great Pyrenees is calculated to be 0.0714 or 7.14%.
Empirical probability is calculated based on observed data. In this case, we want to determine the probability that the next winner of "Best of Show" at the Amboy Kennel Club will be a Great Pyrenees.
Here's the breakdown:
The total number of dog shows held: 42.The number of times a Great Pyrenees has won: 3.The empirical probability (P) is calculated as:
P(Event) = Number of favorable outcomes / Total number of outcomes.
So, the empirical probability that the next winner will be a Great Pyrenees is:
P(Great Pyrenees) = 3 / 42 = 1 / 14 ≈ 0.0714.
Thus, the empirical probability is approximately 0.0714 or 7.14%.
Which choice shows the coordinates of C’ if the trapezoid is reflected across the y-axis?
A) (-5,3)
B) (3,-5)
C) (5,-3)
D) (-3,5)
Answer:
A
Step-by-step explanation:
C is located at (5,3).
If you want to reflect this over the y-axis, you need to have the same distance that (5,3) is to the y-axis on both sides.
If you look at your graph you should see that (5,3) is 5 units a way from the y-axis so when you put it on the other side it should be 5 units a way also.
So the reflection will give you (-5,3)
Answer:
C) (5,-3)

Evaluate 9 ÷ 3[(18 − 6) − 22].
The expression 9 / 3[(18 - 6) - 22] evaluates to -0.3, following the order of operations: first compute the parentheses, then multiply, and finally divide.
To evaluate the expression 9 / 3[(18 - 6) - 22], we need to follow the correct order of operations, often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction). Let's solve it step-by-step:
Next, multiply by 3. Since there are no explicit parentheses around the 3 and the expression, we interpret it as 3 times the result from step 1, 3 * (-10), which equals -30.
Finally, divide 9 by the result from step 2, 9 / -30. That gives us -0.3.
The final answer, after doing the calculations in the correct order, is -0.3.
Describe how to transform the graph of g(x)= ln x into the graph of f(x)= ln (3-x) -2.
Answer:
The graph of g(x) = ㏑x translated 3 units to the right and then reflected
about the y-axis and then translated 2 units down to form the graph of
f(x) = ㏑(3 - x) - 2
Step-by-step explanation:
* Lets talk about the transformation
- If the function f(x) reflected across the x-axis, then the new
function g(x) = - f(x)
- If the function f(x) reflected across the y-axis, then the new
function g(x) = f(-x)
- If the function f(x) translated horizontally to the right
by h units, then the new function g(x) = f(x - h)
- If the function f(x) translated horizontally to the left
by h units, then the new function g(x) = f(x + h)
- If the function f(x) translated vertically up
by k units, then the new function g(x) = f(x) + k
- If the function f(x) translated vertically down
by k units, then the new function g(x) = f(x) – k
* lets solve the problem
∵ Graph of g(x) = ㏑x is transformed into graph of f(x) = ㏑(3 - x) - 2
- ㏑x becomes ㏑(3 - x)
∵ ㏑(3 - x) = ㏑(-x + 3)
- Take (-) as a common factor
∴ ㏑(-x + 3) = ㏑[-(x - 3)]
∵ x changed to x - 3
∴ The function g(x) translated 3 units to the right
∵ There is (-) out the bracket (x - 3) that means we change the sign
of x then we will reflect the function about the y-axis
∴ g(x) translated 3 units to the right and then reflected about the
y-axis
∵ g(x) changed to f(x) = ㏑(3 - x) - 2
∵ We subtract 2 from g(x) after horizontal translation and reflection
about y-axis
∴ We translate g(x) 2 units down
∴ g(x) translated 3 units to the right and then reflected about the
y-axis and then translated 2 units down
* The graph of g(x) = ㏑x translated 3 units to the right and then
reflected about the y-axis and then translated 2 units down to
form the graph of f(x) = ㏑(3 - x) - 2

A mystery number is greater than 50 and less than 100. You can make exactly five different rectangles with the mystery number of tiles. (Hint: This means the mystery number is a square number). Its prime factorization consists of only one prime number. What is the mystery number?
Answer:
81
Step-by-step explanation:
We know the number is between 50 and 100. The prime factorization consists of only one prime number, so the number must be a perfect square. The possible numbers are 64 and 81.
The rectangles that can be made with 64 tiles are:
1×64, 2×32, 4×16, 8×8, 16×4, 32×2, 64×1
The rectangles that can be made with 81 tiles are:
1×81, 3×27, 9×9, 27×3, 81×1
There are 7 rectangles that can be made with 64 tiles. There are only 5 rectangles that can be made with 81 tiles. Therefore, the mystery number is 81.
Step-by-step explanation:
The mystery number is 64, sqare number of 8 , the only prime number contributing to it being 2
Being x the mystery number
[tex]50 < x < 100[/tex]
The only two sqare numbers that meet this request are 64 and 81.
Not knowing much about the above mentioned rectangles, 81 being the perfect square number of a perfect square number we would consider 64 the only posible answer

Mrs. Gomez is a mother to 2 boys. The number of children she has is three times the number of boys she has. Her children are planning to buy her a bouquet of flowers. What is the biggest bouquet they can buy in which the ratio of pink flowers to blue flowers matches the ratio of girls to boys if the florist has 9 blue carnations and 12 pink carnations left?
a bouquet of 12 flowers, 4 pink and 8 blue
a bouquet of 14 flowers, 8 pink and 6 blue
a bouquet of 15 flowers, 6 pink and 9 blue
a bouquet of 18 flowers, 12 pink and 6 blue
Answer:
a bouquet of 18 flowers, 12 pink and 6 blue is correct.
Step-by-step explanation:
Step 1: Find the total number of children.
Number of boys = 2
Total number of children = 3 x number of boys
Total number of children = 3 x 2 = 6
Step 2: Find the ratio of girls to boys
Number of girls = total number of children - total number of boys
Number of girls = 6 - 2 = 4
Girls : Boys
4 : 2
2 : 1
Step 3: Find the ratio of pink and blue flowers
Pink : Blue = Girls : Boys = 2 : 1
Step 4: Check the statements. The ratio of Pink : Blue should be 2 : 1.
1) a bouquet of 12 flowers, 4 pink and 8 blue. Incorrect because in this statement the ratio of pink : blue is 4 : 8 = 1 : 2 instead of 2 : 1.
2) a bouquet of 14 flowers, 8 pink and 6 blue. Incorrect because in this statement the ratio of Pink : Blue 8 : 6 = 4 : 3.
3) a bouquet of 15 flowers, 6 pink and 9 blue Incorrect because in this statement the ratio of pink : blue is 6 : 9 = 2 : 3.
4) a bouquet of 18 flowers, 12 pink and 6 blue. This is correct because the ratio of pink : blue is 12 : 6 = 2 : 1.
!!
Answer:
A bouquet of 12 flowers, 4 pink and 8 blue
Step-by-step explanation:
Let
x----> the number of boys
y ---> the number of girls
z ---> the number of children
we know that
x=2 boys----> equation A
z=3x-----> z=3(2)=6 children ----> equation B
z=x+y ----> equation C
substitute the value of x and the value of z in the equation C and solve for y
6=2+y
y=6-2=4 girls
so
The ratio of girls to boys is equal to
2/4=1/2
therefore
The ratio of pink flowers to blue flowers is equal to 1/2
Let
a -----> the number of pink flowers
b -----> the number of blue flowers
so
For b=9 blue carnations -----> Find the value of a
1/2=a/b
1/2=a/9
a=4.5 pink carnations ----> It doesn't make sense (must be a integer)
For b=8 blue carnations -----> Find the value of a
1/2=a/b
1/2=a/8
a=4 pink carnations ----> It makes sense
therefore
A bouquet of 12 flowers, 4 pink and 8 blue

Give the dimensions of the rectangle with an area of 100 square units and whole
number
side lengths that has:
a. the largest perimeter
b. the smallest perimeter
Answer:
a. 2 and 50
b. 10 and 10
Step-by-step explanation:
Let's denote the side lengths by x and y.
The area is 100 which means that x*y=100.
The only whole numbers which satisfy this are the following:
2,50
4,25
5,20
10,10
Just go through them one by one and find your answer.
The rectangle with an area of 100 square units and whole number side lengths with the largest perimeter is 50 by 2 with a perimeter of 104 units. The smallest perimeter rectangle possible for the same area is a square measuring 10 by 10, which has a perimeter of 40 units.
Explanation:We are tasked with finding the dimensions of a rectangle with an area of 100 square units and whole number side lengths that will result in either the largest perimeter or the smallest perimeter.
Largest Perimeter Rectangle
To find the rectangle with the largest perimeter, we should aim for the rectangle to have the longest possible length and the shortest possible width while still maintaining an area of 100 square units. In the extreme case, this could be a rectangle with a length that approaches infinity and a width that is infinitely small, but we are limited to whole numbers. Therefore, the rectangle with the largest perimeter in this scenario would be 50 by 2, resulting in a perimeter of (50+2)*2 = 104 units.
Smallest Perimeter Rectangle
To find the rectangle with the smallest perimeter, we need to look for the most square-like dimensions, as a square has the smallest possible perimeter for a given area. For an area of 100 square units, the side lengths would be 10 by 10, so the perimeter would be 10*4 = 40 units.
The Discriminant of a quadratic equationis is -6 .What types of solutions does the equation have ?
a.2 irrational solutions
b.1 real solution
c.2 complex conjugate solutions
d.2 rational solutions
Answer:
C
Step-by-step explanation:
The nature of the solutions are determined by the value of the discriminant.
Given a quadratic equation in standard form ax² + bx + c = 0 : a ≠ 0
Then the discriminant is Δ = b² - 4ac
• If b² - 4ac > 0 then 2 real and distinct solutions
• If b² - 4ac = 0 then solutions are real and equal
• If b² - 4ac < 0 then solutions are not real, 2 complex conjugate solutions
Here b² - 4ac = - 6 , hence 2 complex conjugate solutions → C

Please help on this pythagorean question, find x.
Answer:
x = 4
Step-by-step explanation:
Since the triangle is right use Pythagoras' identity to solve for x
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
(x + 3)² + (4(x + 2))² = 25² ← expand parenthesis on left side
x² + 6x + 9 + 16(x+ 2)² = 625
x² + 6x + 9 + 16(x² + 4x + 4) = 625
x² + 6x + 9 + 16x² + 64x + 64 = 625 ← simplify left side
17x² + 70x + 73 = 625 ( subtract 625 from both sides )
17x² + 70x - 552 = 0 ← in standard form
with a = 17, b = 70, c = - 552
Using the quadratic formula to solve for x
x = ( - 70 ± [tex]\sqrt{70^2-(4(17)(-552)}[/tex] ) / 34
= ( - 70 ± [tex]\sqrt{4900+37536}[/tex] ) / 34
= - 70 ± [tex]\sqrt{42436}[/tex] ) / 34
= - 70 ± 206 ) / 34
x = [tex]\frac{-70-206}{34}[/tex] = - 8.1176....
or x = [tex]\frac{-70+206}{34}[/tex] = 4
However, x > 0 ⇒ x = 4
Hence
x + 3 = 4 + 3 = 7 and
4(4 + 2) = 24

[tex]\huge{\boxed{y=\bf{5x+11}}}[/tex]
Distribute the 5. [tex]y-1=5x+10[/tex]
Add 1 on each side. [tex]y=5x+11[/tex]
y−1=5(x+2)
Step 1: Add 1 to both sides.
y−1+1=5x+10+1
y=5x+11
Answer:
y=5x+11
A local restaurant has 20 tables all together with the most popular tables by the window and the salad bar. 5 of the tables are next to the window and another 5 of the tables are next to the salad bar. All of the customers are allowed to seat themselves. If all of the window tables are open, what is the probability that the next two customers will choose to sit at the window?
A. 50%
B. 5.2%
C. 52%
D. 6.2%
Answer:
B. 5.2%
Step-by-step explanation:
Total number of tables = 20
Number of tables next to window = 5
Number of tables next to salad bar = 5
Probability that the first customer chooses the window table = 5 out of 20 = [tex]\frac{5}{20}[/tex]
When this table is chosen, the total remaining tables are 19 out of which 4 tables are next to windows.
So, now the probability that a customer will choose a window table = 4 out of 19 = [tex]\frac{4}{19}[/tex]
Since the selection of two customers is independent of each other, the probability that two customers will chose the window table will be the product of probabilities of their individual selections.
Therefore, the probability that the next two customers will choose to sit at the window = [tex]\frac{5}{20} \times \frac{4}{19} = 0.052[/tex]
Thus, the probability that the next two customers will choose to sit at the window is 0.052 or 5.2%

Answer:
[tex]\large\boxed{r^2=(x+5)^2+(y-4)^2}[/tex]
Step-by-step explanation:
The equation of a circle:
[tex](x-h)^2+(y-k)^2=r^2[/tex]
(h, k) - center
r - radius
We have diameter endpoints.
Half the length of the diameter is the length of the radius.
The center of the diameter is the center of the circle.
The formula of a distance between two points:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Substitute the coordinates of the given points (-8, 2) and (-2, 6):
[tex]d=\sqrt{(6-2)^2+(-2-(-8))^2}=\sqrt{4^2+6^2}=\sqrt{16+36}=\sqrt{52}[/tex]
The radius:
[tex]r=\dfrac{d}{2}\to r=\dfrac{\sqrt{52}}{2}[/tex]
The formula of a midpoint:
[tex]\left(\dfrac{x_1+x_2}{2},\ \dfrac{y_1+y_2}{2}\right)[/tex]
Substitute:
[tex]x=\dfrac{-8+(-2)}{2}=\dfrac{-10}{2}=-5\\\\y=\dfrac{2+6}{2}=\dfrac{8}{2}=4[/tex]
[tex](-5,\ 4)\to h=-5,\ k=4[/tex]
Finally:
[tex](x-(-5))^2+(y-4)^2=\left(\dfrac{\sqrt{52}}{2}\right)^2\\\\(x+5)^2+(y-4)^2=\dfrac{52}{4}\\\\(x+5)^2+(y-4)^2=13[/tex]

Step-by-step explanation:
If the total area of a dartboard is 30,000 mm2 and the area of the second ring
is 15,000 mm2, what is the probability of landing in that second ring?
A. 30%
B. 15%
C. 20%
D. 50%
Answer:
probability is 50 percent
Step-by-step explanation:
total area= 30000
area of secknd ring=15000
therefore 15000/30000 times 100
equals 50 percent
Answer:
Option D.
Step-by-step explanation:
From he given information, we get
Total area of a dartboard = 30,000 mm²
The area of the second ring = 15,000 mm²
We need to find the probability of landing in that second ring.
[tex]Probability=\dfrac{\text{The area of the second ring }}{\text{Total area of a dartboard}}[/tex]
[tex]Probability=\dfrac{15000}{30000}[/tex]
[tex]Probability=0.5[/tex]
Multiply the probability by 100 to find the percentage.
[tex]Probability=0.5\times 100[/tex]
[tex]Probability=50[/tex]
Hence the correct option is D.
what is the input if the output is 0 ?
In other words, what is y if x is 0.
Look on the graph, a line passes through point, [tex]A(x,y)\longrightarrow A(0,-3)[/tex]
So we can conclude that at that very point the input x was 0 and the output y was -3 therefore,
[tex]\boxed{f(-3)=0}[/tex]
Hope this helps.
