The length of each side of the square base should be approximately 244.95 meters when rounded to the nearest hundredth.
To calculate the length of the sides of the square base of the pyramid, we can use the formula for the volume of a square pyramid:
V = (1/3) * (side length)^2 * height
Given that the volume of the pyramid is 2,000,000 m³ and the height is 100 m, we can substitute these values into the formula:
2,000,000 = (1/3) * (side length)^2 * 100
To isolate the side length, we can rearrange the equation:
(side length)^2 = (2,000,000 * 3) / 100
(side length)^2 = 60,000
Taking the square root of both sides, we find:
side length ≈ √60,000
side length ≈ 244.95
Therefore, the length of each side of the square base should be approximately 244.95 meters when rounded to the nearest hundredth.

After drawing a square on the board, Mr. Hinkle asked his class to identify the shape. Timothy stated that Mr. Hinkle had drawn a rhombus. Which of the following statements is true?
Angles A and B are supplementary. Determine the measure of angle A if the measure of angle B is 113.8°.
Answer:
m<A = 66.2°
Step-by-step explanation:
m<A + m<B = 180°
m<B = 113.8°
m<A + 113.8° = 180°
m<A = 180° - 113.8°
m<A = 66.2°
The revenue in dollars of a shoe store is modeled by the expression -4.1x² + 9x + 1,325 where x is the number of shoes sold. The cost of selling the shoes is modeled by the expression -10.1x² - 9.6x +10,000. What simplified expression models the profit in
dollars of the company as a function of x?
The sound emitted from the jet plane has a sound intensity of approximately 149.13 decibels.
How to find determine the expression models the profit in dollars of the company as a function of xUsing the formula:
D = 10 * log(I/I0),
where D represents the sound intensity in decibels, I is the given sound intensity, and I0 is the reference intensity of 10^-12 watts per square meter.
Substituting the given values:
D = 10 * log(8.2*10^2 / 10^-12).
To simplify the calculation, we can rewrite the division as multiplication by the reciprocal:
D = 10 * log(8.2*10^2 * 10^12).
Using the logarithm property log(a * b) = log(a) + log(b):
D = 10 * (log(8.2) + log(10^2) + log(10^12)).
Using the logarithm property log(a^b) = b * log(a):
D = 10 * (log(8.2) + 2 * log(10) + 12 * log(10)).
Since log(10) = 1:
D = 10 * (log(8.2) + 2 + 12).
D = 10 * (log(8.2) + 14).
Using a calculator or logarithm table, we can find log(8.2) ≈ 0.913.
D = 10 * (0.913 + 14).
D = 10 * 14.913.
D ≈ 149.13.
Therefore, the sound emitted from the jet plane has a sound intensity of approximately 149.13 decibels.

Answer: D = 100π square units
Step-by-step explanation:
The formula to calculate the circumference of a circle is C = 2πr, where C is the circumference and r is the radius of the circle.
In this case, we have a circumference of 20π units, so we can set up the equation as follows:
20π = 2πr
To find the radius, we can divide both sides of the equation by 2π:
r = (20π) / (2π)
Simplifying further:
r = 10
Now that we have the radius, we can calculate the area of the circle using the formula A = πr^2:
A = π * (10)^2
A = π * 100
A = 100π
For what value of x is the rational expression below equal to zero?
x-9
(x-4)(x+4)
OA. -4
B.
C.-9
D. 9
SUBMIT
The value of x is 9
To find the value of x for which the rational expression is equal to zero, we need to set the numerator equal to zero:
x - 9 = 0
Solving for x:
x = 9
Therefore, the value of x = 9.
Looking at the denominator (x - 4)(x + 4), we see that it contains two factors: (x - 4) and (x + 4). For the entire expression to equal zero, either the numerator or one of the factors in the denominator must equal zero.
Setting each factor in the denominator equal to zero:
x - 4 = 0 or x + 4 = 0
x = 4 or x = -4
These are the valid values of x for which the rational expression is equal to zero.

Calling card A charges a connect fee of 69¢ plus 1.9¢ perminute. Calling card B has no connect fee but charges 6¢ perminute.
Which system of equations can be used to determine the number of minutes (x) where the price (y) is the same for both cards?
Answer:
16.829 minutes
Step-by-step explanation:
To solve this problem, we need to set up a system of equations based on the given information. Let's define the variables:
Let x be the number of minutes.
Let y be the price in cents.
For calling card A, the price can be calculated using the formula: y = 69 + 1.9x
For calling card B, the price can be calculated using the formula: y = 6x
We want to find the number of minutes (x) where the price (y) is the same for both cards. To set up the system of equations, we equate the two expressions for y:
69 + 1.9x = 6x
Now, we can solve this equation to find the value of x, which represents the number of minutes where the prices are equal.
69 + 1.9x = 6x
To simplify the equation, we can subtract 1.9x from both sides:
69 = 6x - 1.9x
Combining like terms, we have:
69 = 4.1x
To isolate x, we divide both sides of the equation by 4.1:
69 / 4.1 = x
Simplifying the division gives us:
16.829 = x
Therefore, the number of minutes (x) where the price (y) is the same for both calling cards A and B is approximately 16.829 minutes.
Hope this helps!
Answer:
For calling card A: y = 0.019x + 0.69
For calling card B: y = 0.06x
Step-by-step explanation:
For calling card A: y = 0.019x + 0.69
For calling card B: y = 0.06x
Set the prices equal to each other to find when they are the same:
0.019x + 0.69 = 0.06x
Simplify and solve for x:
0.041x = 0.69
x = 16.83 (rounded to two decimal places)
Therefore, if a person expects to talk for 16.83 minutes or more, calling card A will be cheaper. If they expect to talk for less than 16.83 minutes, calling card B will be cheaper.

We have,
To find the derivative of the function [tex]f(w) = 2/(w^2 - 4)^5[/tex], we can use the chain rule and the power rule for differentiation.
Let's go through the steps:

Now, let's differentiate f(w) with respect to w:
[tex]f'(w) = d/dw~ [2(w^2 - 4)^{-5}][/tex]

Using the power rule, the derivative of (w² - 4) with respect to w is 2w.
Applying the chain rule:
[tex]f'(w) = -10 \times 2(w^2 - 4)^{-6} \times 2w[/tex]
Simplifying further:
[tex]f'(w) = -40w(w^2 - 4)^{-6}[/tex]

The missing angles are m ∠1 = 53° and m ∠k = 12°.
Given that are two circles we need to find the missing measures,
Using the concept of intersecting chords angles,
When two chords intersect inside a circle, the angle between the chords is half the sum of the intercepted arcs.
And,
When two chords intersect outside a circle, the angle between the chords is half the difference of the intercepted arcs.
So,
a) m ∠1 = 1/2 [arc LP + arc RQ]
m ∠1 = 1/2 [50°+56°]
m ∠1 = 1/2 × 106°
m ∠1 = 53°
b) m ∠k = 1/2 [arc MJ - arc LR]
arc LR = 360° - [72° + 100° + 140°]
arc LR = 48°
So,
m ∠k = 1/2 [72° - 48°]
m ∠k = 12°
Hence the missing angles are m ∠1 = 53° and m ∠k = 12°.

The correct option is the second one, the order is:

How to find the rates of change?To find the rate of change for a function f(x) on an interval [a, b] we need to get:
R = (f(b) - f(a))/(b - a)
Here the interval is [-1, 3]
The first function is:
f(x)= (x + 3)² - 2
Evaluating we get:
f(-1) = (-1 + 3)² - 2
f(-1) = 2² - 2 = 4 -2 = 2
and f(3) = (3 + 3)² - 2 = 34
Then the rate is:
R = (34 - 2)/(3 + 1) = 8
For g(x) we can use the graph, we have:
R = (0 + 2)/4 = 1/2
For the last function we need to use the table, then we will get:
