Answer: D
Step-by-step explanation:
Answer:
h(x) = -2x^2 -2
Step-by-step explanation:
You know that translating the point (a, b) vertically downward by 3 units will make it be the point (a, b-3).
The same translation works on the point (x, f(x)), or when a=x and b=f(x). Translated downward by 3 units, the point becomes ...
(x, f(x) -3)
You want to name this (x, h(x)), so we have ...
h(x) = f(x) -3
h(x) = -2x^2 +1 -3 . . . substitute the expression for f(x)
h(x) = -2x^2 -2 . . . . . simplify
Answer:
125.660 cm^2
Step-by-step explanation:
Surface area of a right cylinder is A=2πrh+2πr^2
π= 3.14
h= 8 cm
r= 2 cm
A=(2)(3.14)(2)(8) + (2)(3.14)(2)^2
