F (x) = |x + 3| -1 . Find the average rate of change from x = -6 to x = 8

1 answer:

3 0

Average rate of change is (f(8) - f(-6))/(8 - (-6)) = ((|8 + 3| -1) - (|-6 + 3| -1))/(8 + 6) = ((|11| -1) - (|-3| -1))/14 = ((11 - 1) - (3 - 1))/14 = (10 - 2)/14 = 8/14 = 4/7

Jamie receives 15% commission on magazine subscriptions. One week her sales totaled $860. What was her commission?

icang [17]

Given:

Jamie receives 15% commission on magazine subscriptions.

One week her sales totaled $860.

To find:

Her commission.

Solution:

We have,

Total sales of one week = $860

Rate of commission = 15%

Now,

$Commission=\dfrac{15}{100}\times 860$

$Commission=\dfrac{15}{10}\times 86$

$Commission=\dfrac{1290}{10}$

$Commission=129$

Therefore, the amount of commission is $129.

If John is driving 70 mi/hr and Jim is driving 50 ft/min, who is driving faster?

lapo4ka [179]

Answer:

John

Step-by-step explanation:

70 mi/(60 min) ≈ 1 1/6 mi/min.

1 1/6 miles is significantly farther than 50 ft, so John is driving (much) faster.
