[tex](f-g)(x)=2x-6-(3x+9)=2x-6-3x-9=-x-15[/tex]
Answer:
The correct option is C.
Step-by-step explanation:
The correct option is C.
We have given:
f(x) = 2x - 6 and g(x) = 3x + 9
Now we have to find (f-g)(x)
(f-g)(x) = f(x)- g(x)
Now subtract g(x) from f(x)
(2x - 6) - (3x + 9)
Open the parenthesis. When we open the parenthesis the signs of second bracket will become negative because there is a negative sign outside the bracket.
(f-g)(x)= 2x-6-3x-9
Now solve the like terms:
(f-g)(x)= -x-15
Thus the correct option is C....

a circular garden with a radius of 8 feet is surrounded by a circular path with a width of 3 feet. what is the approximate area of the path alone? use 3.14 for tt
Answer:
178.98 square feet
Step-by-step explanation:
Alright so we need to find two areas here and find the difference to find the area of the path.
The two shapes involved is a smaller circle inside a bigger circle.
Let's look at the smaller circle, the gardening area.
You are given is has a radius of 8 ft.
The area of a circle is [tex]\pi \cdot r^2[/tex] where r is the radius.
So the area of the smaller circle is [tex]\pi \cdot 8^2[/tex].
Now time to look at the bigger area (which will have some overlapping area with the smaller one which will subtract out to find the area of path).
The diameter of the smaller circle was (8+8)=16 feet.
What is the diameter of the bigger one. The path is 3 ft wide so we have to add a 3 before the diameter of the smaller circle to another 3 after that diameter to get the diameter of the bigger circle. So the diameter of the bigger circle is (3+16+3)=22 feet. The radius is half the diameter so the radius is 22/2=11.
The area of the bigger circle is [tex]\pi \cdot 11^2[/tex].
The area of the path=
the area of bigger circle - the area of smaller circle=
[tex]\pi \cdot 11^2-\pi \cdot 8^2[/tex]
Type this into your calculator with 3.14 instead of the [tex]\pi[/tex] button.
178.98 square feet
The answer is:
[tex]PathArea=178.98ft^{2}[/tex]
Why?To calculate the are of the path alone, we need to add the width of the path to the radius of the garden in order to know is radius, then, calculate the total area (using garden radius plus path width) and then, subtract it the area of the circular garden.
We know that the radius of the circular garden is equal to 8 feet, and the circular path has a width of 3 feet, so, the radius of the circular path will be:
[tex]CPath_{radius}=8feet+Path_{width}\\\\Path_{radius}=8feet+3feet=11[/tex]
Now, calculating the areas, we have:
Garden Area:
[tex]CircularGardenArea=\pi *radius^{2}\\\\CircularGardenRadius=\pi *8ft^{2}=3.14*64ft^{2}=200.96ft^{2}[/tex]
Total Area:
[tex]TotalArea=\pi *(8feet+3feet)^{2}=\pi *(11ft)^{2}=3.14*121ft^{2}=379.94ft^{2}[/tex]
Now, calculating the area of the path, we have:
[tex]TotalArea=CircularGardenArea+PathArea\\\\PathArea=TotalArea-CircularGardenArea\\\\PathArea=379.94ft^{2}-200.96ft^{2}=178.98ft^{2}[/tex]
Hence, we have that:
[tex]PathArea=178.98ft^{2}[/tex]

They all label the vertices in the correct order and do not label sides when naming it.
Answer:
B. [tex]\Delta TAX[/tex],
D. [tex]\Delta AXT[/tex]
E. [tex]\Delta XTA[/tex].
Step-by-step explanation:
We have been given a triangle. We are asked to choose the valid names for our triangle from the given choices.
We know that labels of the vertices of the triangle are used to name a triangle. In naming triangle, we can start from any vertex and we should keep the letters in order as we go around the triangle.
We can see that vertices of our given triangle are labeled as A, T and X, therefore, we can get three names for our triangle as:
[tex]\Delta TAX[/tex], [tex]\Delta AXT[/tex] and [tex]\Delta XTA[/tex].
Therefore, options B, D and C are correct choices.
The area of circle Z is 64 ft2.
What is the value of r?
r = 4 ft
r = 8 ft
r = 16 ft
r = 32 ft
The value of r that satisfies the given area is approximately 5.08 ft, which is closest to 4 ft.
Explanation:The area of a circle can be calculated using the formula A = πr², where A is the area and r is the radius. In this case, the area of the circle is given as 64 ft². So we can substitute the value of A as 64 ft² in the formula to find the value of r.
64 = πr²
To solve for r, we can divide both sides of the equation by π and then take the square root of both sides.
r² = 64/π
r = √(64/π)
To simplify further, we can approximate the value of π as 3.14.
r = √(64/3.14)
r ≈ 5.08 ft
Based on the given options, the value of r that is closest to 5.08 ft is 4 ft.

The second termn in a geometric sequence is 20. The fourth termn in the same sequense is 45/4, or 11.225. What is the common ratio in this sequence?
Answer:
t2=ar^(2-1)
20=ar
then
t4=ar^(4-2)
45/4=ar.r
45/4=20.r
45/80=r
Answer:
r=±0.75
Step-by-step explanation:
Given:
a2= 20
a4= 45/4
As a geometric sequence has a common ratio and is given by:
an=a1(r)^n-1
where
an=nth term
a1=first term
n=number of term
r=common ratio
Now
a2=20=a1(r)^(2-1)
20=a1(r)^1
20=a1*r
Also
a4=45/4=a1(r)^(4-1)
45/4=a1r^3
(a1*r)r^2=45/4
Substituting value of 20=a1*r
(20)r^2=45/4
r^2=45/4(20)
r^2=0.5625
r=±0.75!
For Valentine's Day, Kelsey got a box of 24 chocolates. After one week, she'd eaten 5/8 of them. How many chocolates had Kelsey eaten?
Answer:
She had eaten 15 chocolates.
Step-by-step explanation:
[tex]\frac{5}{8} * 24 = \frac{120}{8} = 15[/tex]
Final answer:
Kelsey ate 15 chocolates out of the 24 after a week, which is 5/8 of the total. Jenny initially had 14 chocolates before eating two and giving half of the remainder to Lisa.
Explanation:
To solve how many chocolates Kelsey has eaten, we have to calculate 5/8 of 24. Since 24 chocolates multiplied by 5/8 equals 15, Kelsey ate 15 chocolates after one week.
Regarding the second question about Jenny and her chocolates:
If Lisa ends up with 6 chocolates, which represents half of the remainder after Jenny ate two, we can deduce that before giving half to Lisa, there were 12 chocolates.Adding back the two chocolates Jenny ate, she originally had 14 chocolates.In summary, the answer to how many chocolates Jenny initially had is 14.

What is the value of x in the rhombus below?
Answer:
x = 17Step-by-step explanation:
We know:
1. Diagonals of a rhombus are perpendicular.
2. Diagonals divide the rhombus on four congruent right triangles.
3. The sum of measures of acute angles in a right triangle is equal 90°.
Therefore we have the equation:
(2x + 3) + (3x + 2) = 90 combine like terms
(2x + 3x) + (3 + 2) = 90
5x + 5 = 90 subtract 5 from both sides
5x = 85 divide both sides by 5
x = 17
The value of x is 17. This means that the angles formed by the diagonals of the rhombus are 37 degrees (2 * 17 + 3) and 53 degrees (3 * 17 + 2), and they indeed form congruent right triangles as required in the properties of a rhombus.
To find the value of x in the given equation, we start by understanding the properties of a rhombus and how its diagonals divide it into four congruent right triangles.
Given information:
Diagonals of a rhombus are perpendicular.
Diagonals divide the rhombus into four congruent right triangles.
Let's proceed with the steps to solve for x:
Step 1: Recognize that the angles formed by the diagonals are 2x + 3 and 3x + 2. Since these angles are congruent right angles, their sum is equal to 90 degrees.
Step 2: Set up the equation:
(2x + 3) + (3x + 2) = 90
Step 3: Combine like terms:
5x + 5 = 90
Step 4: Isolate x by subtracting 5 from both sides of the equation:
5x = 85
Step 5: Solve for x by dividing both sides by 5:
x = 85 / 5
x = 17
Hence, the value of x is 17. This means that the angles formed by the diagonals of the rhombus are 37 degrees (2 * 17 + 3) and 53 degrees (3 * 17 + 2), and they indeed form congruent right triangles as required in the properties of a rhombus.

[tex](2-x^2)-x[/tex] I replace the x in w(x)=x-2 with 2-x^2

You can graph this to find the range.
But since this is a quadratic (the graph is a parabola), I'm going to find the vertex to help me to determine the range.
The vertex is at x=-b/(2a). Once I find x, I can find the y that corresponds to it by using y=-x^2-x+2.
Comparing ax^2+bx+c to -x^2-x+2 tells me a=-1, b=-1, and c=2.
So the vertex is at x=1/(2*-1)=-1/2.
To find the y-coordinate that corresponds to that I will not plug in -1/2 in place of x into -x^2-x+2.
This gives me
-(-1/2)^2-(-1/2)+2
-1/4 + 1/2 +2
Find a common denominator which is 4.
-1/4 + 2/4 +8/4

So the highest y value is 2 ( I know tha parabola is upside down because a=negative number)

An alloy is a mixture of metals. Suppose that a certain alloy is made by mixing 50 grams of an alloy that 52% copper with 78 grams of pure copper. How many grams of copper are in the resulting mixture? What percent of the resulting mixture is copper?
Answer:
See below in bold.
Step-by-step explanation:
The 50 grams of alloy contains 50 * 0.52 = 26 g of pure copper.
So the amount of copper n the mixture = 78 + 26 = 104 g.
The total mass of the mixture = 78 + 50 = 128 g.
% copper = 104 * 100 / 128
= 81.25%.
Final answer:
The resulting mixture contains 104 grams of copper, which constitutes 81.25% of the mixture.
Explanation:
To find out how many grams of copper are in the resulting mixture of the alloy, we need to calculate the amount of copper from both sources and add them together. The first source is 50 grams of an alloy that is 52% copper, and the second source is 78 grams of pure copper.
50 grams of 52% copper alloy contains 50 grams × 0.52 = 26 grams of copper.78 grams of pure copper is of course 78 grams of copper.Now, add the amounts of copper from both sources:
26 grams (from the alloy) + 78 grams (pure copper) = 104 grams of copper.
To determine what percent of the resulting mixture is copper, we add the total weight of the mixture (50 grams + 78 grams = 128 grams) and then calculate the percentage:
(104 grams copper / 128 grams total) × 100 = 81.25%
So, the resulting mixture contains 104 grams of copper and is 81.25% copper.

Write an equation in slope-intercept form for the line passing through the pair of points. (–1, 2), (4, –3)
Answer:
y = - x + 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 1, 2) and (x₂, y₂ ) = (4, - 3)
m = [tex]\frac{-3-2}{4+1}[/tex] = [tex]\frac{-5}{5}[/tex] = -1, hence
y = - x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (- 1, 2), then
2 = 1 + c ⇒ c = 2 - 1 = 1
y = - x + 1 ← equation in slope- intercept form
The equation is y = –x + 1.
To find the slope-intercept form of a line passing through two points, calculate the slope using the given points and then use one point to find the y-intercept. The final equation for the line through the points (–1, 2) and (4, –3) is y = –x + 1.
To write an equation in slope-intercept form for the line passing through the points (–1, 2) and (4, –3), we first need to calculate the slope (m) using the formula
m = (y2 - y1) / (x2 - x1). Plugging in our points gives us m = (–3 – 2) / (4 – (–1)) = –5 / 5 = –1. Now that we have the slope, we can use one of the points to find the y-intercept (b). Using the point (–1, 2) and the slope-intercept formula y = mx + b, we plug in the values to get 2 = (–1)×(–1) + b, simplifying to 2 = 1 + b, which yields b = 1. Thus, the equation is y = –x + 1.

We can rewrite 8 as 2^3
So, the equation becomes:
2^x = 2^3
Since the bases are the same, we can equate the exponents:
x = 3
Hence, the value of x when f(x) = 8 is 3.

4/15x^3 and 5/12x^2
finding LCM of denominators (15x^3,12x^2)
for variable x, as x^3 is the heighest power so we'll keep x^3
now for the numeric part
15= 3*5
12=3*4
common factor is 3, so
3*4*5 =60
hence LCD= 60x^3!
