Answer:
1326 cm²
Step-by-step explanation:
1) Identify the equation of the surface area of a rectangular prism

2) Input the corresponding values
;
; and
into the equation, and solve for the area

3) ∴ 
A. 8 feet * 0.9 = distance after first bounce
h(n) = 8 * 0.9^n
b. 8 * 0.9^14 = 1.83 feet to 2 d.p.
1.83 * 12 = 21.96 inches
I you use 1 gallon cost is 0.08(1) + 5 = 5.08
If 2 0.08(2) + 5 = 5.16 etc Increase is 0.08
For every extra 1 gallon the water increase is $0.08
Answer:
(f+g)(2) = 10
Step-by-step explanation:
f(x)=2x^2+3x
g(x)=x-2
(f+g)(x) will be sum of f(x) and g(x)
(f+g)(x) = 2x^2+3x + x - 2 = 2x^2+4x - 2
we have to find (f+g)(2), for that we will put x = 2
(f+g)(x) = 2x^2+4x - 2

Thus, (f+g)(2) is 10.
