Answer 1
Sorry this is a late response, I have just got done taking it myself. The answer is 3/5. You have 40 and 32, so you try figuring out (since you're simplifying) the LOWEST common multiple in this case. Since you always put the smallest number (the ones given to you which in this case is 32) as the numerator, the largest [is 40] making it the denominator. Apparently, the answer is 3/5. I argue that because there is no number between these two that three goes into, since the smallest that goes into 32 is 4. If they'd fix the answer, it'd be 4/5. Other than that, put down 3/5.
Answer 2

The trigonometric ratio for sin z is the ratio of the length of the opposite side to the length of the hypotenuse in a right triangle.

The trigonometric ratio for sin z is defined as the ratio of the length of the opposite side to the length of the hypotenuse in a right triangle. In other words, if we have a right triangle with angle z, sin z is equal to the length of the side opposite to angle z divided by the length of the hypotenuse.

Mathematically, sin z = opposite/hypotenuse.

For example, if we have a right triangle with angle z, and the length of the opposite side is 3 units and the length of the hypotenuse is 5 units, then sin z = 3/5.

In poker probability calculations, there are 2,598,960 possible five-card hands, various specific hand combinations such as those containing a king or four aces have their own probability, which can be determined using the formulas for combinations.

Calculations for Poker Probabilities

The subject of probability in a poker hand involves various combinations and permutations. Here's how the calculations are made:

Total number of five-card poker hands: The total number is calculated using combinations, as the order in which cards are drawn does not matter. This is given by the combination formula C(n, r) = n! / (r!(n-r)!), where n is the total number of available cards (52), and r is the number of cards drawn (5). Thus, there are 52! / (5!(52-5)!)= 2,598,960 possible hands.

Number of ways one king can be selected: There are four kings in a deck, so there are C(52, 5) - C(48, 5) ways to choose a hand with at least one king, as you subtract the number of hands without any kings from the total number of hands.

Number of ways four aces can be selected: There is only one way to choose all four aces, and then there are 48 remaining cards to choose the fifth card from, which gives 48 combinations.

Number of ways of getting four aces and one king: There are four kings to choose from and one specific combination of aces, so there are 4 ways to have a hand with four aces and one king.

what is the 8th term in the following sequence 28,33,38,43.....

Answers

To solve this, you have to figure out how they created the sequence, i.e., how did they get from 28 to 33 and then from 33 to 38 (etc.). If you subtract 28 from 33 the answer is 5, and the same is true for all the consecutive numbers in the sequence, so you have to add five to 43 to figure out the next term. You already have four terms, so we only need 4 more:
28, 33, 38, 43, 48, 53, 58, 63   63 is the 8th term.

d. Power set of b, its cardinality
Power set is the set of all possible combinations of elements.
There are 2^n members in the power set of x where n is the number of elements in the set x.
For example, power set of S={1,2} is {[tex]\phi[/tex],{1},{2},{1,2}}
The cardinality of S above is the number of elements in the set, therefore 2^2=4.

For b={0,2,4,6}
The power set is
{[tex]\phi[/tex],{0},{2},{4},{6},{0,2},{0,4},{0,6},{2,4},{2,6},{4,6},{0,2,4},{0,2,6},{0,4,6},{2,4,6},{0,2,4,6}}
for a total of 2^4=16 members in the power set.
Therefore the cardinality of the power set is 16.

 

The union of A and B is {-1, 0, 1, 2, 3, 4, 6}, the intersection is {2, 4}, and the difference B - A is {0, 6}. The power set of B contains 16 subsets.

Set Operations: Union, Intersection, Difference, and Power Sets

Let's solve the given problems step by step:

a. The union of sets A and B (A ∪ B)

A ∪ B represents all unique elements that are in either set A or set B.

Given: A = {-1, 1, 2, 3, 4} and B = {0, 2, 4, 6}

A ∪ B = {-1, 0, 1, 2, 3, 4, 6}

b. The intersection of sets A and B (A ∩ B)

A ∩ B represents all elements that are present in both sets A and B.

A ∩ B = {2, 4}

c. The difference of sets B and A (B - A)

B - A represents all elements that are in set B but not in set A.

B - A = {0, 6}

d. The power set of B and its cardinality

The power set of a set is the set of all its subsets, including the empty set and the set itself. If a set has n elements, its power set will contain 2^n subsets.

B = {0, 2, 4, 6}

The power set of B is: { {}, {0}, {2}, {4}, {6}, {0, 2}, {0, 4}, {0, 6}, {2, 4}, {2, 6}, {4, 6}, {0, 2, 4}, {0, 2, 6}, {0, 4, 6}, {2, 4, 6}, {0, 2, 4, 6} }

The cardinality of the power set of B is 2^4 = 16.

In summary:

A ∪ B = {-1, 0, 1, 2, 3, 4, 6}

A ∩ B = {2, 4}

B - A = {0, 6}

The power set of B has 16 elements.

What is the equation, in slope-intercept form, of the line that is perpendicular to the line y – 4 = –(x – 6) and passes through the point (−2, −2)?

Answers

That line is in point-slope form:

[tex]\sf y-y_1=m(x-x_1)[/tex]

Where 'm' is the slope and (x1, y1) is a point on the line.

Perpendicular lines have opposite slopes. To get the opposite, we take the reciprocal and multiply it by -1.

[tex]\sf -1[/tex]

Reciprocal:

[tex]\sf -\dfrac{1}{1}\rightarrow -\dfrac{1}{1}\rightarrow -1[/tex]

Multiply by -1:

[tex]\sf 1[/tex]

We can plug this slope and the point into point-slope form, and then convert it to slope-intercept form.

[tex]\sf y-y_1=m(x-x_1)[/tex]

[tex]\sf y-(-2)=1(x-(-2))[/tex]

Negatives cancel out:

[tex]\sf y+2=1(x+2)[/tex]

Distribute 1 into the parenthesis:

[tex]\sf y+2=x+2[/tex]

Subtract 2 to both sides:

Determine the equation for the parabola graphed below.

Answers

The general equation for a parabola is: y = a(x - b)^2 + c
So given the vertex is at (-1, 7), this means that b = -1 and c = 7:
y = a(x + 1)^2 + 7
Then we substitute a point from the graph (aside from the vertex). The easiest is the y-intercept of (0, 5):
5 = a(1)^2 + 7
a = -2
Therefore the equation is: y = -2(x + 1)^2 + 7 = -2x^2 - 4x + 5

The equation for the parabola graphed below is  [tex]y = -2(x + 1)^2 + 7 = -2x^2 - 4x + 5[/tex]

A parabola's general equation is: y = a(x - b)2 + c

Given that the vertex is located at (-1, 7), this means that b = -1 and c = 7:

y = a(x + 1)^2 + 7

Then, instead of the vertex, we replace a point from the graph. The y-intercept of (0, 5) is the simplest:

5 = a(1)^2 + 7

a = -2

As a result, the equation is as follows: [tex]y = -2(x + 1)^2 + 7 = -2x^2 - 4x + 5[/tex]

Answers

Q1)
the lateral area of the pyramid is the total area of all the lateral faces excluding the base.
In this regular octagonal pyramid, the lateral sides are triangles. As there are 8 triangles we need to find the area of all 8 sides.
Area of one lateral triangle face = 1/2 * base * slant height 
slant height is the hypotenuse of the right angled triangle formed from the base of the pyramid with the perpendicular height.
slant height - l
l² = 7² + 7² = 49 *2
 l²  = 98 
l = √98
l = 9.9
Area = 1/2 * 5.8 cm * 9.9 cm 
         = 28.71 cm²
There are 8 sides 
total lateral area = 8 * 28.71 = 229.68 rounded off is 229.7 cm²
third option is correct - 229.7 cm²

Q2)
in the triangular face, the lateral edge makes a 60° angle with the base edge. Therefore 2 of the angles are 60° each, since the sum of the interior angles of a triangle is 180°, the third angle too is 60°. this makes the triangle an equilateral triangle with equal angles, hence equal sides. 
since lateral edge is 8 cm,base edge too is 8 cm. 
since this is an equilateral triangle, the perpendicular line cuts the base edge at its midpoint, bisecting the line forming 2 right angled triangles.
in the right angled triangle, height of triangle is x slant height ,
base = 8 /2 = 4 cm
hypotenuse = 8 cm
We need to find x, use Pythogoras' theorem 
4² + x² = 8²
16 + x² = 64
x² = 62 - 16
x = √48
x = √4x√4x√3
  = 2x2√3
  = 4√3 cm

Q3)
surface area of the square pyramid 
surface area of the base + surface area of triangular faces 
square area = length x length 
                    = 6.2 x 6.2 
                    = 38.44 yd²
triangular face area = 1/2 * length * height 
since the angle between lateral edge and base edge is 60°, its an equilateral triangle where all sides are equal. in this case each side is 6.2 yd. 
to find the perpendicular height, use pythogoras' theorem
the perpendicular line(slant height ) cuts the base edge at its midpoint, therefore length of the right angled triangle is = 6.2/2 = 3.1 yd

slant height - l
l² + 3.1² = 6.2²
l² = 38.44 -9.61
l²  = 28.83 
l = 5.37
area = 1/2 *length *height 
        = 1/2 * 6.2 * 5.37
        = 16.64 yd²
there are 4 triangles = 4 * 16.64 = 66.58 yd²
total area = 38.44 + 66.58 = 105 yd²
correct answer is 3rd option - 105 yd²

The slope is 1/2 throughout the entire line.

Looking at the first triangle, the rise is 2 and the run is 4.  That gives us a slope of 2/4 = 1/2.

For the second triangle, the rise is 1 and the slope is 2.  This gives us a slope of 1/2.

In a triangle, the length of any side is greater than the difference of the lengths of the other two sides and less than the sum of the lengths of the other two sides.

34 mm - 24 mm = 10 mm

Weston is buying a house for $215,000. He is financing $185,000 and obtained a 30-year, fixed-rate mortgage with a 6.525% interest rate. How much are his monthly payments?

$1,005.94

$1,362.48

$1,614.09

$1,172.37,

Answers

$1,172.37 The formula for calculating the payment on a loan is P = r(PV)/(1 - (1 + r)^(-n)) where P = Payment PV = Present value r = interest per period n = number of periods Since there's 12 months per year and the loan is for 30 years, there will be 12 * 30 = 360 periods. The interest rate per month will be 0.06525 / 12 = 0.0054375, and finally, the present value is the size of the loan at 185000. Now let's substitute and solve. P = r(PV)/(1 - (1 + r)^(-n)) P = 0.0054375(185000)/(1 - (1 + 0.0054375)^(-360)) P = 1005.9375/(1 - (1.0054375)^(-360)) P = 1005.9375/(1 - 0.141961802) P = 1005.9375/0.858038198 P = 1172.369134 P = 1172.37 So the monthly interest and principle payments are $1,172.37 Note: The actual payments will be higher since the above figure doesn't include insurance and taxes.
For this problem, we will be using the formula for loan:

PMT=P[(r/n)/1-(1+r/n)^-ny]
where: 
P=Principal Value
r=rate
n=number of compoundings/year

To solve:
*Weston is only financing $185,000.

P=$185,000
r=6.525% or 0.06525
n=12 (monthly)
year=30

Jenna's parents required her to put $10 of her $50 monthly allowance into a savings account for what percent of her monthly allowance did this represent?

Answers

$10 is 20% of $50 dollars therefore the answer is it represented 20% of her monthly allowance

Final answer:

To determine the initial amount needed in a bank account to reach $10,000 in ten years with 10% compound interest, use the compound interest formula.

Explanation:

To find out how much money you need to put in a bank account to have $10,000 in ten years with 10% interest compounded annually:

Use the formula for compound interest: A = P(1 + r/n)^(nt)

Plug in the values: $10,000 = P(1 + 0.10/1)^(1*10)

Solve for P: P = $10,000 / (1.10^10)

Calculation:

PV = FV / (1 + r/n)^(n*t)

Inserting the known values:

PV = $10,000 / (1 + 0.10/1)^(1*10)

PV = $10,000 / (1.10)^10

Calculating the exponent:

PV = $10,000 / 2.59374

Finally:

PV = $3,855.43 (approximately)

Therefore, you need to put approximately $3,855.53 into the bank account initially.

Hope this helps!

for the final answer do i add the 5 to (x+1) making it 5x+5 or do i leave it how it is? Also how do i find the domain

Answers

You don't "add the 5" in any event. Multiplication is very different from addition, and precision of vocabulary is important.

It depends on what your teacher or answer key expect. You can take a hint from the fact that the given polynomials are all multiplied out.

(5x^2 +5)/(x -1)

_____
The domain of polynomials in general is "all real numbers." However, you must exclude any specific numbers that make the rational expression be undefined. This includes numbers that make the denominator of the numerator zero, as well as those that make either the numerator or the denominator of the denominator zero. In other words, you must exclude from the domain

John says the transformation rule (x, y) es002-1.jpg (x + 4, y + 7) can be used to describe the slide of the pre-image (4, 5) to the image (0, –2). What was his error?

Answers

John didn't check his work.

The appropriate transformation rule is (x -4, y-7).

_____
John's signs were in error.

Sample Response: The pre-image is the point you start with. To check the transformation rule, substitute the values of the coordinates (4, 5) into the rule. You get (4, 5) → (4+4, 5+7). Simplify to get (4, 5) → (8, 12). This is the image. Instead the rule was applied to the image. This is the source of the error.


Kail Ryans 10 laps around the track each day each lap around the track is 400 m meters how many times around the track will she need to run a total of 12 kilometers

Answers

hello

1 km = 1000 m

12 km = 12,000 m

Each day, she runs 10 * 400 m = 4000 m

12,000 m / 4000 m = 3

It will take 3 days.

Have a nice day

Exponential Growth/Decay Function

Hint/Tip:

Remember, the basic general exponential function form is: y = Abx In detail, b is written as (1-r) where r is the rate of growth or decay, so our detailed formula is: y = A(1-r)x

Always work with the rate as a decimal number, not as percentage. If the rate is given as percent (%), you will need to divide it by 100 to have the decimal form.

The value of a car is $21,500. It loses 12% of its value every year.

(a) Write a function that represents the value y (in dollars) of the car after x years.

(b) Use the function to estimate the value of the car after 6 years. (round your answer to the nearest whole number)

Answers

(a) Write a function that represents the value and (in dollars) of the car after x years.
 For this case what we should do is write the equation of exponential type.
 We have then:
 y = A (b) ^ x
 Substituting the values:
 y = 21500 (0.88) ^ x
 Answer:
 y = 21500 (0.88) ^ x

 (b) Use the function to estimate the value of the car after 6 years. (round your answer to the nearest whole number)
 We use the function found in part (a) and evaluate for x = 6.
 We have then:
 y = 21500 (0.88) ^ 6
 y = 9985 $
 Answer: 
 the value of the car after 6 years is: 
 y = 9985 $










































You and your friend are standing back-to-back. Your friend runs 16 feet forward and then 12 feet right. At the same time, you run 12 feet forward and then 9 feet right. You stop and throw a baseball to your friend, who catches it. How far did you throw the baseball?

Answers

You would throw a baseball 9 feet and your friend would catch the baseball. Hope this helps!
Let's assume that you stared at the origin.  So your friend moved 16 units along the x-axis and 12 down the y-axis landing him at (16, -12), while you on the other hand run 12 feet forward along the x-axis, and 9 units into the negative y area.  This makes you at (-12, -9).  So solve graph these points.  Use the graph to count the difference between the 2 x coordinates, you should get 28, the solution for the y distance (ignore the negatives) is 3.  So we can use the Palagorien Theorem to solve.  (28)2 + (3)2 = x2.  Solve for x.

784+9=x2
793=x2
