For this case what we should do is evaluate the function in each of the points from 2 to 7 and then find the average.
We have then:
f (x) = ln (3x) +2.5.
f (2) = ln (3 * 2) + 2.5 = 4.291759469
f (3) = ln (3 * 3) + 2.5 = 4.697224577
f (4) = ln (3 * 4) + 2.5 = 4.98490665
f (5) = ln (3 * 5) + 2.5 = 5.208050201
f (6) = ln (3 * 6) + 2.5 = 5.390371758
f (7) = ln (3 * 7) + 2.5 = 5.544522438
Then the average is:
Average = (4.291759469 + 4.697224577 + 4.98490665 + 5.208050201 + 5.390371758 + 5.544522438) / (6) = 5.019472516

5.02
Answer:
the average rate of change of f (x) from 2 to 7 is 5.02
Improper Fraction =75/14
Mixed Number=5 5/14
Answer:

Answer:
Options (B) and (E)
Step-by-step explanation:
Area of ΔABC = 
= 
= 42 in²
Area of trapezoid ADEC = 
[Here, 
and 
are the parallel sides and 'h' is the height of the isosceles trapezoid given]
= 
= 96 in²
Area of the pentagon = Area of triangle ABC + Area of trapezoid ADEC
= 42 + 96
= 138 in²
Therefore, Options (B) and (E) are the correct options.
Answer:
Step-by-step explanation:
=x^2-x+3+3x^2-3x+2
=5x^2-4x+5
