Answer:
(a) The net change of the function is 12.
(b) The average rate of change of the function 4.
Step-by-step explanation:
The average rate of change of function 
over the interval 
is given by this expression:
average rate of change = 
It is a measure of how much the function changed per unit, on average, over that interval.
Given:
(a) To find the net change of the function, first we calculate the values of 
and 
The net change is simply the difference
(b) The average rate of change takes the net change and divides it by the change in the 
value.
Answer: 3
Step-by-step explanation:
Let say x the width of the tank,
x+4 its length,
x+2 its height
<u>width=3</u>
length=3+4=7
height=3+2=5
Answer:
Step-by-step explanation:
area of base = π4² = 16π in²
lateral area = 2πrh = 2π·4·6 = 48π in²
surface area = 2×16π + 48π = 80π in² ≅ 251.3 in²
Answer:
I cannot really see the q
Answer:
2.9 in.
Step-by-step explanation:
Let x in be the width of the larger rectangle. If the length of the larger rectangle is 4 inches and the perimeter of the larger rectangle is 14 in, then
If two rectangles are similar, then their lengths and widths are proportional with the scale factor k. Thus, the length of the smaller rectangle is 
in and the width of the smaller rectangle is 
in. If the perimeter of the smaller rectangle is 10 in, then
