Answer:
It all depends on the type of coins stacked
The stack of coins with the greatest volume is the one with the largest number of coins and the largest diameter.
Final Answer: The stack of coins with the greatest volume is the one with the largest number of coins and the largest diameter.
To calculate the volume of a stack of coins, we can use the formula for the volume of a cylinder,[tex]V = πr^2h,[/tex] where V is the volume, r is the radius of the coin, and h is the height of the stack.
Since each stack has the same height, we only need to compare the volumes based on the number of coins and their diameter.
First, let's assume the radius of each coin is r and the height of each stack is h. Let's denote the number of coins in each stack as n.
Now, let's calculate the volume for each stack:
1. Stack 1: Volume = [tex]πr^2 * h * n1[/tex]
2. Stack 2: Volume = [tex]πr^2 * h * n2[/tex]
3. Stack 3: Volume = [tex]πr^2 * h * n3[/tex]
Since all stacks have the same height (h), we can disregard it in the comparison.
To compare the volumes, we need to compare the number of coins (n) and the radius of the coins (r).
Let's assume Stack 1 has the largest number of coins, followed by Stack 2 and then Stack 3.
If all stacks have the same number of coins, then the one with the largest diameter (which is the radius times 2) would have the greatest volume.
After calculating the volumes for each stack, we can determine which stack has the greatest volume based on the number of coins and their diameter.
Complete question:
If each stack of coins has the same height, which stack of coins has the greatest volume?

Answer:
The measure of angle B is 54°. The measure of angle A is 51°. The measure of angle AFE is 47°.
Step-by-step explanation:
According to exterior angle theorem: It a triangle
Exterior angle = Sum of opposite interior angles
In triangle BED,
[tex]\angle AEF=\angle B+\angle D[/tex]
[tex]82=\angle B+28[/tex]
[tex]82-28=\angle B[/tex]
[tex]54=\angle B[/tex]
The measure of angle B is 54°.
In triangle ABC,
[tex]\angle ACD=\angle A+\angle B[/tex]
[tex]105=\angle A+54[/tex]
[tex]105-54=\angle A[/tex]
[tex]51=\angle A[/tex]
The measure of angle A is 51°.
In triangle AEF,
Using angle sum property,
[tex]\angle A+\angle E+\angle AFE=180[/tex]
[tex]51+82+\angle AFE=180[/tex]
[tex]133+\angle AFE=180[/tex]

Which of the following are identities? Check all that apply.
Answer:
Options A and D.
Step-by-step explanation:
To check the identities we have to check each option given.
A. tan(x - π) = tanx
We take left hand side (L.H.S.) of the equation.
tan(π - x) = tanx [ since we know tan(π ± x) = tanx ]
So L.H.S. = R.H.S.
It's an identity.
B. sin(x + y) + sin(x - y) = 2cosx siny
We take L.H.S. first
sin(x + y) + sin(x - y)
= sinx coxy + siny cosx + sinx cosy - cosx siny
= 2sinx cosy ≠ R.H.S.
Option B is not an identity.
C. cos(x + y) - cos(x - y) = 2cosx cosy
We take L.H.S. of the equation.
cos(x + y) - cos(x - y) = cosx cosy - sinx siny - (cosx cosy + sinx siny)
= -2sinx siny ≠ R.H.S.
Therefore, option C is not an identity.
D. cos(x + y) + cos(x - y) = 2cosx cosy
We take L.H.S. of the equation.
cos(x + y) + cos(x - y) = cosx cosy - sinx siny + cosx cosy + sinx siny
= 2cosx cosy = R.H.S.
Therefore, option D is an identity.
Options A and D are the identities.

Match each cross section with its perimeter
64 inches
26 inches
48 inches
34 inches
Answer:
64 inches : cross-section, cube, 16 inches
26 inches : right rectangular prism, 10x 3 x 14 inches
48 inches : cube with 12-inches edges
34 inches : rectangular prism, 5x12x4 diagonal of 13 inches
Step-by-step explanation:
right rectangular prism, 10x 3 x 14 inches
The cross-section is parallel to the base, so it cuts the height, maintaining the length and width. So, we have:
P = 10 + 3 + 10 + 3 = 26 inches
cube with 12-inches edges
This time, the cross-section is done perpendicular to the base, but in this case it doesn't matter since it's a cube... so it could be done in any direction and it wouldn't change the result.
P = 12 + 12+ 12 + 12 = 48 inches
rectangular prism, 5x12x4 diagonal of 13 inches
The cut is done perpendicular to the base, but along a diagonal of 13 inches, so the height is preserved, and the diagonal length becomes the new side other than height.
P = 13 + 4 + 13 + 4 = 34 inches
cross-section, cube, 16 inches
Again, the cross-section is done parallel to the base, but in this case it doesn't matter since it's a cube... so it could be done in any direction and it wouldn't change the result.
P = 16 + 16 + 16 + 16 = 64 inches.

What is the midpoint of AC
ANSWER
B) (m+p,n+r)
The coordinates are :
A(2m,2n)
B(2p,2r)
To find the x-coordinate of the midpoint of AB, we add the x-coordinates of the two points and divide by 2.
[tex]x = \frac{2m + 2p}{2} [/tex]
Factor
[tex]x = \frac{2(m + p)}{2} [/tex]
Simplify:
[tex]x = m + p[/tex]
Similarly, the y-coordinate is
[tex]y = \frac{2n + 2r}{2} [/tex]
[tex]y = \frac{2(n + r)}{2} [/tex]
[tex]y = (n + r)[/tex]
Hence the midpoint is
(m+p,n+r)

What is the vertex of the quadratic function f(x) = (x – 8)(x – 2)?
Answer:
(5, - 9)
Step-by-step explanation:
Given
f(x) = (x - 8)(x - 2) ← in factored form
Find the zeros by equating f(x) to zero, that is
(x - 8)(x - 2) = 0
Equate each factor to zero and solve for x
x - 8 = 0 ⇒ x = 8
x - 2 = 0 ⇒ x = 2
The vertex lies on the axis of symmetry which is located at the midpoint of the zeros, hence
[tex]x_{vertex}[/tex] = [tex]\frac{8+2}{2}[/tex] = 5
Substitute x = 5 into f(x) for corresponding y- coordinate
f(5) = (5 - 8)(5 - 2) = (- 3)(3) = - 9
vertex = (5, - 9)
Answer: (5,-9)
Step-by-step explanation:
Make the multiplication indicated:
[tex]f(x) = x^2-2x-8x+16[/tex]
Add the like terms:
[tex]f(x) = x^2-10x+16[/tex]
Now find the x-coordinate of the vertex with this formula:
[tex]x=\frac{-b}{2a}[/tex]
In this case:
[tex]b=-10\\a=1[/tex]
Then:
[tex]x=\frac{-(-10)}{2(1)}=5[/tex]
Rewrite the expression with [tex]f(x)=y[/tex]
[tex]y = x^2-10x+16[/tex]
Now substitute [tex]x=5[/tex] into the function to find the y-coordinate of the vertex:
[tex]y = (5)^2-10(5)+16[/tex]
[tex]y =-9[/tex]
Therefore, the vertex is:
(5,-9)

The table below shows two equations:
Equation 1 |4x − 3|− 5 = 4
Equation 2 |2x + 3| + 8 = 3
Which statement is true about the solution to the two equations?
* Equation 1 and equation 2 have no solutions.
* Equation 1 has no solution, and equation 2 has solutions x = −4, 1.
* The solutions to equation 1 are x = 3, −1.5, and equation 2 has no solution. *
* The solutions to equation 1 are x = 3, −1.5, and equation 2 has solutions x = −4, 1.
Answer:
Option C is correct.
Step-by-step explanation:
Equation 1 |4x − 3|− 5 = 4
Adding +5 on both sides
|4x − 3|− 5 +5 = 4 +5
|4x − 3| = 9
Apply absolute rule:
IuI = a and a>0 then u = a and u = -a
so, 4x-3 = 9 and 4x-3 = -9
Solving
4x = 9+3 and 4x = -9+3
4x = 12 and 4x = -6
x = 12/4 and x = -6/4
x = 3 and x = -3/2 or -1.5
Equation 2 |2x + 3| + 8 = 3
Adding -8 on both sides
|2x + 3| + 8 -8 = 3 -8
|2x + 3| = -5
Apply absolute rule:
IuI = a and a>0 then u = a and u = -a
But we cannot apply absolute rule because in our case a < 0 i.e -5
So, Equation 2 has no solutions.
Hence Option C The solutions to equation 1 are x = 3, −1.5, and equation 2 has no solution is correct.

ILL GIVE U BRAINLIEST AND 30 POINTS
HELP
Final answer:
The probability that a given event does not occur in any of the trials when an experiment is repeated n times is calculated using the formula (1 - P(A))^n, where P(A) is the probability of the event occurring in a single trial.
Explanation:
The question is about finding the probability that a given event does not occur in any of the trials when an experiment is repeated n times. Let's denote the probability of the event occurring as P(A) and the probability of the event not occurring as P(~A). The probability that an event does not occur in a single trial is 1 - P(A). Therefore, if the experiment is repeated n times independently, the probability that the event does not occur in any of these trials is given by (1 - P(A))^n. This formula arises from the principle that for independent events, the probability of both events A and B occurring is the product of their individual probabilities, P(A) and P(B). Since each trial is independent, and we are looking for the event not happening across all n trials, we multiply the probability of it not happening in one trial by itself n times.
