Answer:
-8x^3 + 64x^2 - 24x
Step-by-step explanation:
To distribute, we must multiple -8x to each term:
-8x(x^2) - 8x(-8x) - 8x(3)
-8x^3 + 64x^2 - 24x
D - 90 because 20 x 30 and multiply by 0.15
Answer:
B. 30 ft
Step-by-step explanation:
The ladder is 32 ft long
The angle of elevation of the ladder is 70°
The height (h) of the top of the ladder to the ground is what we are to find.
= sin 70°
h = 32 × sin 70° = 30.07016387 or 30 ft (rounded off to nearest feet)
Answer:x10
Step-by-step explanation:
Answer:
Step-by-step explanation:
Our Sample size is 42 rocks total. If we want to pick one red rock out of the 42, we first have to determine the possibility of doing that from the numbeer of red rocks we have total. There are 6 red rocks, so the probability of picking one of those is
6/42 or 1/7
There are 14 blue rocks. So the probability of picking one of those is
14/42 or 1/3
There are 22 white rocks. So the probability of picking one of those is
22/42 or 11/21
