Answer:
g(-5) = -127
Step-by-step explanation:
Plug in -5 for x:
g(-5) = (-5)^3 - 2
= -125 - 2
= -127
Answer:
10.4 cm
Step-by-step explanation:
The volume (V) of a pyramid is calculated using
V = area of base × height (h)
area of square base = 6² = 36, thus
× 36h = 120
12h = 120 ( divide both sides by 12 )
h = 10 cm
To find the slant height (s) consider the right triangle from the vertex to the midpoint of the base and from the midpoint of base to the side.
That is a right triangle with hypotenuse s and legs 10(h) and 3 (midpoint of the base )
Using Pythagoras' identity then
s² = 10² + 3² = 100 + 9 = 109
Take the square root of both sides
s = ≈ 10.4 cm
Answer:
150
Step-by-step explanation:
100 : 160 :: e : 240 proportion
160e = (100)(240)
160e = 24000
elves = 150
