<h2>Answer:</h2>

The average change in the price of stock over the three weeks is:

       It decreased by 30 cents per week.

<h2>Step-by-step explanation:</h2>

It is given that the price of stocks decreased by 60 cents one week.

It decreased by 10 cents in the next week

and 20 in the third week.

Hence, the average rate of change is calculated as the ratio of the sum of the change in the three weeks divided by the number of weeks i.e. 3.

Hence,

\text{Rate\ of\ change}=\dfrac{-60-10-20}{3}\\\\\\\text{Rate\ of\ change}=\dfrac{-90}{3}=-30

As the average rate of change is negative this means that the price of the stocks decreased.

and it decreased by a rate of 30 cents per week.

Give a numerical example to represent this rule.
RideAnS [48]

A non-negative number is a number which is either zero or a positive number

For numerical example , to satisfy rule \sqrt[k]{a^{m} } =(\sqrt[k]{a} )^{m} substitute a = 16, m = 2 and k = 2

The square root of a number is the number that we need to multiply by itself to get the original number

Now substituting, a = 16, m = 2 and k = 2 in given rule

            \sqrt[2]{16^{2} } =(\sqrt[2]{16} )^{2} \\\\\sqrt[2]{16*16}=\sqrt[2]{16}*  \sqrt[2]{16}\\\\16=16

So,  \sqrt[2]{16^{2} } satisfy the given rule.

Answer:

h = 4.5 inches

Step-by-step explanation:

The area of a trapezoid is given by

A = 1/2 (b1+b2) h

We know A b1 and b2

20.25 = 1/2 (5+4)*h

20.25 = 9/2 h

Multiply each side by 2/9 to isolate h

2/9 * 20.25 = 2/9 *9/2 h

4.5 =h
