Answer:
fifth option
Step-by-step explanation:
Given
- 2(x - 5) ≤ 6x + 18 ← distribute left side
- 2x + 10 ≤ 6x + 18 ( subtract 6x from both sides )
- 8x + 10 ≤ 18 ( subtract 10 from both sides )
- 8x ≤ 8
Divide both sides by - 8, reversing the sign as a result of dividing by a negative quantity, thus
x ≥ - 1
G(x)= -x^2-3
So the answer is A
We know that the volume of a sphere is:
V
=
4
3
π
r

where
r
=
10
2
=
5
ft
is the radius;
we need half of this, so we use:
V

giving a total weight of water of:
W
=
