The height of the prism that's depicted in the water tank will be 8m.
How to calculate the height of the prism?The area of the base of the triangular prism will be calculated thus:
= 1/2 × 4 × 9
= 18m²
The volume of water removed from the rectangular tank will be:
= (6 × 6) × 4
= 144m³
Therefore, the height will be calculated thus:
18 × h = 144
18h = 144
h = 144/18
h = 8m
Therefore, the height is 8m.

Given y=f(x), when f(x) = -3 on the graph of y=√f(x)
a. is undefined
b. intersects y=f(x) on the x-axis
c. is above the graph of y=f(x)
d. intersects the graph of y=f(x)
e. is below the graph of y=f(x)
A. 2
B. -2
C. 0
D. -2
Answer:
d. -2 <= y <= infinity
Step-by-step explanation:
The graph starts at -2 with a solid (colored in) point on the -2. So there are no y's less than -2 on the graph.
The graph continues to go up. Yes, it goes to the right, but we are looking at the y's. There is an arrow at the right end of the graph which means it continues to go up forever.
-2 <= y <= infinity
Dolbear's law states the relationship between the rate at which Snowy Tree Crickets chirp and the air temperature of their environment. The formula is T=50+n-40/4, where T is a temperature in degrees Fahrenheit and N is a number of chirps per minute. If T=57°F, find the number of chirps per minute.
Answer:
Number of chirps per minute = 68
Step-by-step explanation:
Given:
T = 50+ (N - 40)/4
where,
T is a temperature in degrees Fahrenheit
N is a number of chirps per minute
Find n when T = 57°F
T = 50 + (N - 40)/4
57 = 50 + (N - 40)/4
57 - 50 = (N - 40)/4
7 = (N - 40)/4
Multiply both sides by 4
7 × 4 = (N - 40)/4 × 4
28 = N - 40
28 + 40 = N
68 = N
N = 68
Number of chirps per minute = 68

Answer:
m = 2.4 and b = 14.8
Step-by-step explanation:
In slope-intercept form, all equations follow the formula y = mx + b, in which equations are parallel as long as they have the same slope, represented by the variable m. All that the b variable does is change the y-intercept. Knowing this, in order to find a parallel equation to y = 2.4x + 5.2 that intercepts the point (-2, 10), the only variable that can change is the b variable. The first step is to plus -2 into the x variable. This will grant you y = 2.4(-2) or y = -4.8, which will then allow you to find what the b variable should be by subtracting -4.8 from 10. This will grant you b = 14.8, and since you know the slope must stay the same, the final answers are m = 2.4 and b = 14.8.

An office supply store purchased a case of binders for $600. The profit (P) to be made on the binders is defined by the function
P(b) - 8.50b - 600, where b is the number of binders sold.
Part A What is the range of the function if the domain is {10, 45, 72, 100)?
Part B What do the domain and range represent in this situation?
Part C What is the minimum number of binders that the store needs to sell in order to make a profit (P >0)? Show or explain your work.
Part D What is the minimum profit the store can make on the sale of these binders? Show or explain your work.
Answer:
Part A
Domain = input values
Range = output values
Therefore, if the domain is {10, 45, 72, 100} then input those values into the function:
P(10) = 8.50(10) - 600 = -515
P(45) = 8.50(45) - 600 = -217.5
P(72) = 8.50(72) - 600 = 12
P(100) = 8.50(100) - 600 = 250
So the range is {-515, -217.5, 12, 250}
Part B
The domain is the number of binders sold
The range is the profit in dollars
Part C
Set the function to >0:
⇒ P(b) > 0
⇒ 8.50b - 600 > 0
add 600 to both sides:
⇒ 8.50b > 600
divide both sides by 8.50:
⇒ b > 70.58823529...
Therefore, the minimum number of binders the store needs to sell in order to make a profit is 71.
Part D
If the store sells a minimum of 71 binders, then substitute b = 71 into the function and solve to find the minimum profit:
⇒ P(71) = 8.50(71) - 600
⇒ P(71) = 603.5 - 600
⇒ P(71) = 3.5
Therefore, the store will make a minimum of $3.50 profit if it sells at least 71 binders.
However, if the store sells less than 71 binders, it will make a loss.
