Excuse me but his answer is incorrect. To find the proper rate of change you might have to solve it like you would for slope.
First you would find the points for x = 3 and x = 15 would be (3, 0.08) and (15, 327.68). Then using the slope formula you can find 327.60/ 12. That gives 27.3. So in that case the correct answer is C.

Answer:

Option C is correct

27.3    

Step-by-step explanation:

Average rate of change A(x) of f(x) over interval [a, b] is given by:

A(x) = \frac{f(b)-f(a)}{b-a}              .....[1]

As per the statement:

Given the function:

f(x) = 0.001 \cdot 2^x

At x = 3

then;

f(3) = 0.001 \cdot 2^3 = 0.01 \cdot 8 = 0.08

At x = 15

then;

f(3) = 0.001 \cdot 2^15 = 0.01 \cdot 32768= 327.68

Substitute these given values in [1] we have;l

A(x) = \frac{f(15)-f(3)}{15-3} = \frac{3267.8-0.08}{12} =\frac{327.6}{12} = 27.3

Therefore, the average rate of change from x = 3 to x = 15 is, 27.3

Find ordered pair that is solution for liner equation 4x - 5y=20
Nat2105 [25]

Answer:

(0,-4) (5,0)

Step-by-step explanation:

4x-5y=20

First, we must put the equation into slope intercept form: y= mx+b

5y=4x-20=y=4/5x-4

The y intercept, by definition, is b. In this scenario, b is -4.

One ordered pair that works is (0,-4).

Also, we can find the ordered pair for the x intercept. By definition, the x intercept is the value of x when y equals zero. hence, we substitute 0 for y and then we can find an ordered pair that works and solve for x!:

  1. 0=4/5(x)-4= 4=4/5x
  2. 4x=20
  3. x=5

Therefore, (5,0) works as well!

2<br> v<br> What is the equation of a line that is parallel to y = -4x – 3 and shifted down 3 units?
Ugo [173]

Answer: y=-4x-6

Step-by-step explanation:

Given

The equation of line is y=-4x-3

The line which is parallel to the given line is y=-4x+c

and shifted by 3 units down i.e. its y-intercept is 3 units below the given line

\therefore y=-4x-3-3\\\Rightarrow y=-4x-6
