<span>f(x) = x2 − 16
y = x2 - 16
x = y2 - 16
+ 16 to both sides
x+16 = y2
divide both sides by 2
1/2x+8 = y</span>

NISA [10]

Answer:

{ \tt{average =  \frac{f(1) + f(5)}{2} }} \\  \\  = { \tt{ \frac{( {1}^{2}  - 1 - 6) + ( {5}^{2} - 5 - 6) }{2} }} \\  =  \frac{ - 6 + 14}{2}  \\  \\  = { \tt{4}}

Write the expanded form of the decimal 0.082¯ using powers of 10
Softa [21]

Answer:

0.082 = 8.2× 10^-2

Step-by-step explanation:

Given the decimal number 0.082, the expanded form using the power of 10 can be gotten by writing the decimal number in standard format(writing as a multiple of 10).

To do that we will shift the decimal point to the front up to the front of digit 8. This shows that the decimal point will be shifted 2times to the front. Since of is shifted 2times to the front, our power of 10 will be -2.

0.082 = 8.2× 10^-2

This gives the required answer.

Note that, the power of 10 is positive when decimals are shifted to the back and negative when shifted to the front(in this case).
