Answer:
y = -2x + 4
y - 2 = -2(x + 1)
y - 2 = -2x - 2
y = -2x
Step-by-step explanation:
Answer:
It's the second choice ⁶√2.
Step-by-step explanation:
Convert to fractional exponents:
√2 = 2^1/2
∛2 = 2^1/3
√2 / ∛2
= 2^1/2 / 2^1/3 = 2^(1/2-1/3)
= 2^(1/6)
Now change back to radicals:
= ⁶√2.
Answer:
7.6 ft
Step-by-step explanation:
The volume of a sphere is
V = 4/3 pi r^3
A hemisphere is 1/2 of a sphere
V = 1/2 (4/3 pi r^3)
V = 2/3 pi r^3
920 = 2/3 pi r^3
Multiply each side by 3/2
920 * 3/2 = 3/2 * 2/3 pi r^3
1380 = pi r^3
Divide each side by pi
1380/pi = pi r^3 / pi
1380/ pi = r^3
Using pi as 3.14
1380/3.14 = r^3
439.4904459= r^3
Taking the cube root of each side
(439.4904459)^(1/3)= r^3^(1/3)
7.602967711=r
To the nearest tenth
7.6 = r
