A rectangular prism has a length of  1 1/4 centimeters, a width of 4 centimeters, and a height of 3 1/4centimeters.
Svetllana [295]

Answer:

16.25 cubic cm

Step-by-step explanation:

The volume of a prism is found using V = l*w*h. Here l = 1.25, w = 4 and h = 3.25. Substitute and simplify.

V = 1.25(4)(3.25)

V = 16.25

A culture is grown with a population of 45 million cells. The cell population is found to double every hour. What will the popul
Alexandra [31]
45 million * 2^{4} = 45million * 16 = 720million

Or you can use 
y=Ae^{kt}
A is equal to 45 million
To find the rate, k, we can plug in:
90million=45million*e^{k*1}&#10;
2=e^{k}
k=ln(2)
y=4.5*10^{7}*e^{t *ln2}
Knowing that t = 4
y = 4.5*10^{7}*e^{ln(2)*4}&#10;
y = 720 million

Which change will triple the lateral surface area of a cone?
Fudgin [204]
The answer for this would be the second answer choice
This is because when the slant height is tripled, the overall lateral surface area is tripled
The best way to explain this would be through an example. 

Say that the lateral height is 2 and the radius is 1. The lateral surface area is 6.28

Now, if I make the lateral height 6, which is triple the original lateral height, the lateral surface area becomes 18.84, which is triple the original surface area

Therefore, the answer is choice 2

Hope this helped!! :D
