Answer:
20 mm^3
Step-by-step explanation:
Formula
V = 1/3 B * h
Givens
B = 15 mm^2
h = 4 mm
Solution
V = 1/3 * 15 * 4
V = 20 mm^3
a constant of proportionality is a number you have to multiply x by to get y.
y=kx is the equation that expresses the proportionality of x and y
the constant of proportionality is k, so k=-5

Answer:
a) 
b) The population increases 7.1% each year.
Step-by-step explanation:
The continuous population growth model is given by:

In which
is the population after t years,
is the initial population and r is the growth rate.
In this problem, we have that:
A population grows from its initial levelof 22,000 at a continuous growth rcte of 7.1% per year.
This means that 
a) Write a function to model the population increase.


b) By what percent does the populaiion increase each year?

So the population increases 7.1% each year.
x=-12 i got this answer because -14 is 8 more than -6 so i added 8 to -4 and i got -12
hope it helps
