Explain how you find the average rate of change for a linear function.<br><br> PLEASE

Olin [163]

Step-by-step explanation:

The average rate of change is constant for a linear function. Another way to state this is that the average rate of change remains the same for the entire domain of a linear function. If the linear function is y=7x+12 then the average rate of change is 7 over any interval selected. y=mx+b , where m is the slope.

What is the volume of a square pyramid if the perimeter of the base is 44 in and the height is 19 in.? Round to the nearest tent

Verdich [7]

Answer:

766.3 square inches

Step-by-step explanation:

The volume of pyramid is given by

volume = 1/3(area of base) * height of pyramid

Given shape of base is square and

Perimeter of that square is 44inches

We know that perimeter for square is given by 4* length of side

Thus,

44 inches = 4* length of side

 Length of side = 44/4 = 11 inches

_____________________________________________

Area of square is given by side*side.

Thus, area of square base of pyramid is = 11*11 inches square = 121 inches square

Now that we have area of base and height of pyramid .

Substituting these value in formula for volume of pyramid we have

volume = 1/3(area of base) * height of pyramid

 volume = 1/3*(121) * 19 = 2,299

 volume = 766.33

Volume of square pyramid rounded to nearest tenth is 766.3 square inches

The interest rate r required to increase your investment p to the amount a in t years is found by . Find the interest rate r for

Dahasolnce [82]

Answer:

The interest rate was of 0.1173 = 11.73%.

Step-by-step explanation:

This is a simple interest problem.

The simple interest formula is given by:

$E = P*I*t$

In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.

After t years, the total amount of money is:

$A = E + P$
