Use the rules of exponents to simplify the expressions. Place a final answer in fraction form. (-1/2)to the power of 3 *(-1/2) t
Pavlova-9 [17]

Answer:

-1/32

Step-by-step explanation:

we have

(-\frac{1}{2})^{3} )(-\frac{1}{2})^{2})

Remember that

The exponent "product rule" tells us that, when multiplying two powers that have the same base, you can add the exponents

so

(-\frac{1}{2})^{3} )(-\frac{1}{2})^{2})=(-\frac{1}{2})^{3+2})=(-\frac{1}{2})^{5})=-\frac{1}{32}

These tables represent a quadratic function with a vertex at (0,3). What is the average rate of change for the interval from X =
Eva8 [605]

Answer:

-19

Step-by-step explanation:

The missing table is shown in the attachment.

Since the quadratic function has vertex at (0,3), its equation is of the form;

y = a {x}^{2}  + 3

To find the value of 'a' we substitute any other point from the table say (1,2) to get:

2 = a( {1)}^{2}  + 3

a = 2 - 3 =  - 1

Hence the function is

y =  -  {x}^{2} +  3

Now

f(10) =  - 100 + 3 =  - 97

f(9) =  - 81 + 3 =  - 78

The average rate of change from x=9 to x=10 is

\frac{f(10) - f(9)}{10 - 9}  =  \frac{ - 97 -  - 78}{1}  =   - 19
