Answer:
W(x) = $50 + ($14/hr)x
Step-by-step explanation:
Let W(x) represent Wendy's earnings, and x the # of hours she worked.
Then W(x) = $50 + ($14/hr)x
First we substitute, what that means in here is that 2(c +3)
Or minus I can't see the sign but what we do is we substitute 2 with c so that becomes 2c and 2 with 3 and that becomes 6 which gives us 2c + 6 = c-13
Now we can either add 13 on both sides or subtract 6 on both sides, we can do this because they are like terms even if they are negative because they don't have any variable behind it. We will add 13 because we do the opposite of the sign you are solving some get 2c + 19 = c now we subtract 2c on both sides and we get 19 = -1c and at the end we divide -1 on both side and we get -19 = c or
c = -19.
Answer:
the answer to C. Is 3/8.
The answer to D. Is 5/8.
Step-by-step explanation:
Perhaps you mean to find the volume under
? It seems like you have to rely on calculus otherwise (in the case that you indeed mean
).
Assuming this, note that
describes the top half of a sphere with radius 8, which means the volume below this surface over the disk
is simply half the volume of the sphere. Thus the volume is
