Which expression below gives the average rate of change of the function h(x)=4^(x+2)+7 on the interval –3 ≤ x ≤ 5?
viktelen [127]

Answer:

\frac{4^8-1}{32}

Step-by-step explanation:

h(x)=4^{(x+2)} +7

We know that formula for average rate of change of a function from a to b is

\frac{f(b)-f(a)}{b-a}

Here f equals h and a =-3 b=5

h(a) = 4^{5+2} +7 = 4^7+7

and

h(b) = 4^{-3+2} +7 = \frac{1}{4} +7

h(b)-h(a) =4^7-\frac{1}{4} =\frac{4^8-1}{4}

b-a = 5-(-3) =8

Hence average rate of change is

\frac{4^8-1}{4}(\frac{1}{8} )=\frac{4^8-1}{32}

What’s this answer?
ANTONII [103]

Answer:

x=2, y=1

Step-by-step explanation:

The left and right sides are equal

7x-2 = 5x+2

Subtract 5x from each side

7x -5x-2 = 5x-5x+2

2x-2 = 2

Add 2 to each side

2x -2+2 = 2+2

2x = 4

Divide by 2

2x/2 = 4/2

x =2

The top and the bottom are the same length

6x+y = 7x-1

6(2) +y = 7(2)-1

12 +y = 14-1

Subtract 12 from each side

12 +y-12 = 13-12

y = 1

A friend asked lara to help her divide 456.3 by 100. what should lara tell her? a. move the decimal point three places to the ri
Alex73 [517]

Answer:

Step-by-step explanation:

The correct answer is D.  If we are multiplying by 10 we would move the decimal place one place to the right to show that the number is now 10 times bigger.  If we multiply by one hundred.  We are getting 100 times bigger, so we would move the decimal place 2 places to the right.

The opposite is true if we are dividing.  Instead of moving the decimal to the right to show that the number is getting bigger, we move to the left to show that the number is getting smaller.  If we are getting smaller by 10, we would move the decimal one place to the left. In this case, we are getting 100 times smaller so we move the decimal two places to the left.
