Find the volume of the regular hexagonal prism with side lengths of 4 ft, height of 3ft and apothem of approximately 3.5 ft
Answer:
A(p) = 84 ft³
Step-by-step explanation:
Volume of regular prism is equal to V(p):
V(p) = Area of the face * h
we know h = 3 ft
A regular hexagonal prism has 6 equal sides forming its face.
Finding the area (A₂) of a triangle formed by center of the prism, straight lines between the center and two adjacents vertex and side between these two vertex, and then multiply that area by 6 (number of equal triangles inside hexagonal prism) we get the area of the face, but we need further consideration, the triangle described above, has doble area of (A₁), the triangle formed by apothem, half side, and straight line between center of the face and the vertex, therefore.
Area of small triangle = base * height
A₁ = (1/2) * 4 * 3,5
A₁ = 2*3,5
A₁ = 7 ft²
A₂ = 2* 7
A₂ = 14 ft²
Finally volume of the hexagonal prism is:
V(p) = 6 * 14
A(p) = 84 ft³
The stock of Company A gained 5% today to $34.65. What was the opening price of the stock in the beginning of the day?
To find the opening price of the stock, we can subtract the 5% gain from the current price. The opening price of the stock in the beginning of the day was approximately $36.47.
Explanation:To find the opening price of the stock, we need to deduct the 5% gain from the current price of $34.65.
Let x be the opening price.
Since the stock gained 5%, the opening price minus 5% of the opening price equals the current price: x - 0.05x = 34.65.
Simplifying the equation, we get 0.95x = 34.65. To solve for x, divide both sides of the equation by 0.95.
The opening price of the stock in the beginning of the day was approximately $36.47.

Help please. Find the value of x in the isosceles triangle shown below
Answer:
A
Step-by-step explanation:
We need to use some properties of an isosceles triangle and the Pythagorean Theorem.
First, the vertical line down the middle of the triangle is the height, which means the angle is makes with the base is 90 degrees and it bisects the base. So, we have two right triangles, each with a height of 6 and with a base of 4/2 = 2.
We can now use the Pythagorean Theorem, which states that for a right triangle with legs a and b and hypotenuse c:
a² + b² = c²
Here, a = 6 and b = 2 and x = c, so:
a² + b² = c²
6² + 2² = x²
x² = 36 + 4 = 40
x = √40
Thus, the answer is A.
Answer:
A
Step-by-step explanation:
This triangle contains two congruent right angle triangles
x² = 6² + 2²
x² = 36 + 4
x² = 40
x = sqrt(40)
x = 4sqrt(10)

5,8,11,7? If the mean of the data set is 8 points, find the missing number of points.
Answer:
9
Step-by-step explanation:
if you add 5,8,9,11,and 7 you get 40 then you need to divide it by 5 because their are 5 numbers so then 40 divided by 5 is 8 so the number is 9
Final answer:
To determine the missing number in the data set with a mean of 8, we set up the equation 8 = (5 + 8 + 11 + x) / 4. Solving for x, we find that the missing number is 8.
Explanation:
To find the missing number in the data set 5, 8, 11, ?, where the mean is 8 points, we can use the formula for the mean of a data set. The mean is the sum of all data points divided by the number of points. Since we know the mean and three of the four numbers, we can create an equation to solve for the missing number:
Mean = (Sum of all data points) / (Number of data points)
8 = (5 + 8 + 11 + x) / 4
Now, solve for x:
8 * 4 = 5 + 8 + 11 + x
32 = 24 + x
x = 32 - 24
x = 8
Therefore, the missing number is 8.
The graph of the parent function f(x) = x3 is transformed such that g(x) = f(–2x). How does the graph of g(x) compare to the graph of f(x)? g(x) is stretched horizontally and reflected over the y-axis. g(x) is stretched horizontally and reflected over the x-axis. g(x) is compressed horizontally and reflected over the y-axis. g(x) is compressed horizontally and reflected over the x-axis.
The correct answer is: g(x) is compressed horizontally and reflected over the y-axis.
To understand how the graph of [tex]\( g(x) = f(-2x) \)[/tex] compares to the graph of the parent function [tex]\( f(x) = x^3 \)[/tex], we need to analyze the effects of the transformations applied to [tex]\( f(x) \)[/tex].
1. The transformation [tex]\( f(-x) \)[/tex] would reflect the graph of [tex]\( f(x) \)[/tex] over the y-axis. This is because for every point [tex]\( (x, y) \)[/tex] on the graph of [tex]\( f(x) \)[/tex], there will now be a corresponding point [tex]\( (-x, y) \)[/tex] on the graph of .
2. The transformation [tex]\( f(2x) \)[/tex] would compress the graph of [tex]\( f(x) \)[/tex] horizontally by a factor of 2. This is because for every point [tex]\( (x, y) \)[/tex] on the graph of [tex]\( f(x) \)[/tex], there will now be a corresponding point [tex]\( \left(\frac{x}{2}, y\right) \)[/tex] on the graph of [tex]\( f(2x) \)[/tex]. The x-values are halved, which means the graph is compressed along the x-axis.
Combining these two transformations, [tex]\( g(x) = f(-2x) \)[/tex] indicates that the graph of [tex]\( f(x) \)[/tex] is first compressed horizontally by a factor of 2 and then reflected over the y-axis.
Therefore, the graph of [tex]\( g(x) \)[/tex] is compressed horizontally and reflected over the y-axis when compared to the graph of the parent function [tex]\( f(x) \)[/tex].

Misha solves the equation 3 x minus 2 (x + 3) = 4 (x minus 2) minus 7 by applying the distributive property to each side of the equation. The result is 3 x minus 2 x minus 6 = 4 x minus 8 minus 7. Misha then wants to combine like terms. Which are the terms Misha should combine?
Answer:
2(x+3)=4
2x+6=4
2x=4-6
2x=-2
2x÷2
x=1
Answer:
The terms that Misha should combine are 3x – 2x and –8 – 7
Step-by-step explanation:
Misha have the equation : 3x-2(x+3) = 4(x-2)-7
After applying distributive property, a(b+c) = ab+ac
3x - 2x - 6 = 4x - 8- 7 ..............(1)
Now, we need to combine the like terms, like terms are the terms having the same coefficient and combining them means to combine their coefficients.
In equation (1), 3x and -2x are like terms as it have the same coefficient x
Hence we will solve them and get (3-2)x = x
Similarly, -8 and -7 can be solved and we get -7-8 = -15
Now, the equation becomes, x-6 = 4x-15
Then, again collecting the like terms on L.H.S and R.h.s and then solving, we get

Bette has a life insurance policy that will pay her family $40,000 per year if
she dies. Bette's insurance company expects that it would have to put
$2,500,000 into a bank account so that it could make the payments. What
does Bette's insurance company expect the interest rate to be?
O A. 0.4%
O B. 2%
O C. 2.3%
O D. 1.6%
Divide the yearly payout by the amount in the bank:
40,000 / 2,500,000 = 0.016
Multiply by 100 to get the percentage:
0.016 x 100 = 1.6%
The answer is D. 1.6%
The insurance company expects an interest rate of 1.6% to provide the yearly payment of $40,000, calculated by dividing the annual payment by the principal amount deposited.
The student's question asks to calculate the interest rate expected by Bette's insurance company in order to provide a yearly payment of $40,000 to her family, given that the company needs to deposit $2,500,000 into a bank account.
To find the interest rate, we can use the formula for simple interest: Interest = Principal times Rate times Time. Since we are looking for the rate and are given the annual interest (the yearly payment) and the principal (the amount deposited), we can rearrange the formula to solve for the rate: Rate = Interest / Principal / Time. Here, Interest is $40,000, Principal is $2,500,000, and Time is 1 year.
Plugging in the values gives us: Rate = $40,000 / $2,500,000 / 1 = 0.016 or 1.6%. Therefore, the expected interest rate is 1.6%, which corresponds to option D.

The formula for the volume of a cone is V= 1/3pir^2h where V represents the volume, r represents the radius of the base, h represents the height. What is the height of a cone with a volume of 66 cubic centimeters and a base with a radius of 3 centimeters?
The height of the cone is approximately 7.01 centimeters.
We know the volume (V) is 66 cubic centimeters and the radius (r) is 3 centimeters. Substitute these values into the formula:
V = 1/3πr²h
66 = 1/3 × π × 3² × h
Simplify the equation:
Multiply both sides by 3:
200 = π × 9 × h
Cancel out the common factor of 9:
200/9 = π × h
Solve for the height (h):
Divide both sides by π:
h = 200/9π
Then, we have that;
h ≈ 7.01 cm
Therefore, the height of the cone is approximately 7.01 centimeters.
