X) = 3 ln(x)
g(x=2) = 3 ln(2)
g(x=4) = 3 ln(4) = 3 ln(22) = 6 ln2
We have two ordered pairs:
(x,3 ln(2)) and (4,6 ln(2))
The average rate of change is the slope (m) of the secant line connecting the two points:
m = (6 ln2 - 3 ln2)/(4-2) = 3ln(2)/2 ≅ 1.04
Answer:
62.8 cubic inch
Step-by-step explanation:
For Cylinder
height (h) = 5 in
radius (r) = 2 in
Volume of Cylinder
= <em>π r² h</em>
= 22/7 * 2 * 2 * 5
= 22* 20/7
= 440/7
= 62.8 cubic inch
Thus, the volume of the cylinder is <em><u>62.8 cubic inch</u></em>
We need to find 30% of 20 gallons.
1) We can write a proportion
20 gallons ---- 100%
x gallons --------30%
x = 20*30/100 = 6 gallons
2) Or we can write 30% as decimal.
30% = 30/100 = 0.3
0.3 of 20 = 0.3*20 =6 gallons
Answer 6 gallons are used efficiently.
