Answer:
Step-by-step explanation:
Common ratio r = a₂/a₁ = -9/27 = -⅓
b(1) = 27
b(n) = b(1)rⁿ⁻¹ = 27(-⅓)ⁿ⁻¹
First four terms would be n = 1, 2, 3, 4
f(1) = 3 ( 1 )( 1 + 3 )
= 3 * 4
=12
f(2) = 3 ( 2 )( 2 + 3 )
= 6 * 5
= 30
f(3) = 3 ( 3 )( 3 + 3 )
= 9 * 6
= 54
f(4) = 3 ( 4 )( 4 + 3 )
= 12 * 7
= 84 hope this helps!
A slope of -3 can be written as a fraction of -3 over 1.
In terms of rise over run, that means when we subtract 3 from y we add 1 to x.
So plot (1, 3), then go down 3 and over 1 and plot that point.
Make a line between them and you're done.

The volume of a square pyramid is a^2 * h/3, assuming a is the base edge and h is the height. Plug the numbers in and you get your answer.
