Answer:
15 inches
Step-by-step explanation:
Volume of a pyramid = 1/3 x ( length² x height)
4500 = 1/3 x ( length² x height)
height = 1/2 x length
4500 = 1/3 x ( length² x 1/2length)
multiply both sides of the equation by 6
27000 = ( length² x length)
find the cube root of 27300
length = 30
height = 1/2 x 30 = 15in

Answer: a. 450
b. 7950
Step-by-step explanation:
If Cheryl earns 6% interest during the 6 years she will have
(7500*6)/100=450
450 is the interest that she received
her new balance will be
7500+450=7950
If e-the initial hight of the tree, and the function imply some brackets like
f(x)=30/(1+29e-0.5x) then
for every

the rate of growth is negative, the maximum growth per unit of time would be 30ft
If

then

so the tree couldn't be 2ft tall initially
if the brackets are something like
f(x)=30:(1+29e)-0.5x then the results may differ
