Answer:
10
Step-by-step explanation:
"three times r" = 3r
"three times r minus ten" = 3r - 10
"product of 5 and the difference of three times r minus ten"
= 5 (3r - 10)
given that r = 4,
the expression becomes
5 (3r - 10)
= 5 [3(4) - 10]
= 5 [12 - 10]
= 5 (2)
= 10

Answer:
Step-by-step explanation:
The extrema will be at the ends of the interval or at a critical point within the interval.
The derivative of the function is ...
f'(x) = 3x² -4x -4 = (x -2)(3x +2)
It is zero at x=-2/3 and at x=2. Only the latter critical point is in the interval. Since the leading coefficient of this cubic is positive, the right-most critical point is a local minimum. The coordinates of interest in this interval are ...
f(0) = 2
f(2) = ((2 -2)(2) -4)(2) +2 = -8 +2 = -6
f(3) = ((3 -2)(3) -4)(3) +2 = -3 +2 = -1
The absolute maximum on the interval is f(0) = 2.
The absolute minimum on the interval is f(2) = -6.
Answer: Choice B) -5.2 degrees
=====================
Work Shown:
Add up the given temperatures
-42 + (-17) + 14 + (-4) + 23 = -26
Then divide by 5 since there are 5 values we're given
-26/5 = -5.2
Multiply each number one by one
Do long multiplication(google it)
The average rate between two points is calculated the same way you would calculate the slope of a line (rise/run).
96-36/8-3
= 60/5
= 12
