Answer:
R(p) = -4p^2 + 300p when p=20.
R(p) = -4(20)^2 + 300(20)
R(p) = -1600 + 6000
R(p) = 4400
The mass when p=20 years is 4400.
Answer:
12 because 1:2 so times 6 we get 6:12
Step-by-step explanation:
Answer:
2 miles
Step-by-step explanation:
We can use ratios to solve this problem
3/4 miles x miles
--------------- = ---------------
3/8 hours 1 hours
Using cross products
3/4 * 1 = 3/8 * x
Multiply by 8/3 to isolate x
3/4 * 8/3 = 3/8*8/3 *x
8/4 = x
2 =x
