Answer:

$43.64

Step-by-step explanation:

If the tax rate = 3.9% and the product u are buying is priced at $42

Then, the amount you will pay for the object will be,

$42 + 3.9/100 * 42

=> 42 + 0.039 * 42

=> 42 + 1.638

=> 43.638

43.638 when rounded to the nearest hundredth is,

43.64

What is the average rate of change for the sequence shown below? (-.5, 2.5), (0,3. (.5, 3.5). (1,4)

zhannawk [14.2K]

Answer:

The average rate of change for this sequence is 1

Step-by-step explanation:

The average rate of change is calculated as the slope of the line joining the end points of the sequence.

In this case the end points are;

(-.5, 2.5) and (1,4)

We simply calculate the slope using the gradient formula;

Change in y / change in x

(4 - 2.5)/(1 - -0.5) = 1

Need help question #4. Show steps please

poizon [28]

Answer:

Step-by-step explanation:

We are given the integral:

$\displaystyle \int_1^2\frac{x^7-4x^3+6}{x^2}\, dx$

And we want to select its equivalent form.

We can simply divide the fraction. Therefore:

$=\displaystyle \int_{1}^2\frac{x^7}{x^2}-\frac{4x^3}{x^2}+\frac{6}{x^2}\, dx$

Simplify:

$\displaystyle =\int_1^2 x^5-4x+6x^{-2}\, dx$

Our answer is C.
