Answer:
The slope is -4/7 and the y-intercept is -8/7.
Step-by-step explanation:
y+4=-4/7(x-5)
7y+28=-4(x-5)
7y+28=-4x+20
7y=-4x-8
y=-4/7x-8/7
Answer:
48π or 150.72
Step-by-step explanation:
The formula for the volume of a cylinder is V=πr^2h
Simply plug in the values:
V = π4^2 * 3
The answer, in terms of pi, would be:
V = 48π
However, if you use 3.14 for pi, it would be:
V = 150.72
Here is your answer z^6 - 6z^5k + 15z^4k^2 - 20z^3k^3 + 15z^2k^4 - 6zk^5 + k^6

Answer:
(1) 56 miles/hour
Step-by-step explanation:
We need to find the average rate of change from t = 2 to t = 9.
At t = 2 hours, d = 106 miles.
At t = 9 hours, d = 498 miles.
The average rate of change in function f(x) from x = a to x = b is
[f(b) - f(a)]/(b - a)
average rate of change from t = 2 to t = 9 =
(498 - 106)/(9 - 2) = 392/7 = 56
Answer: (1) 56 miles/hour
