Consider the table for the exponential function, LaTeX: p\left(x\right)=2^xp ( x ) = 2 x, shown below. Calculate the Average Rat
Mice21 [21]

Answer:

15

Step-by-step explanation:

To find the average rate if change of the exponential function between the interval [2, 6], use the formula, m = \frac{p(b) - p(a)}{b - a}

Where,

a = 2, p(2) = 4

b = 6, p(6) = 64

Plug in the above values into the formula:

m = \frac{64 - 4}{6 - 2}

m = \frac{60}{4}

m = 15

Average rate of change is 15

A calculator was purchased for $29. The wholesale cost was $20. What was the percent markup?
Oxana [17]
If you would like to find the percent markup, you can calculate this using the following steps:

x% of $20 is $29
x% * 20 = 29
x/100 * 20 = 29
x = 29 * 100 / 20
x = 145%

145% - 100% = 45%

The correct result would be 45%.
