How do you find the average rate of change for f(x)=9-x^2 between two points: x=0 to x=3?

ICE Princess25 [194]

Answer:

The average rate of change is -3.

Step-by-step explanation:

We are given the function:

$f(x)=9-x^2$

And we want to find the average rate of change from x = 0 to x = 3.

In other words, we will compute the function at the two endpoints, and then find the slope of the line that crosses the two points.

For our first endpoint at x = 0, our function evaluates to:

$f(0)=9-(0)^2=9$

So, our first point is (0, 9).

For our second endpoint at x = 3, our function evaluates to :

$f(x)=9-(3)^2=0$

So, our second point is (3, 0).

Then by the slope formula, our average rate of change will be:

$\displaystyle m=\frac{0-9}{3-0}=\frac{-9}{3}=-3$

Make x the subject of the formula y = (ax)2

katovenus [111]

Answer:

y = (ax)2

y = 2ax

divide both sides by 2a to make x the subject of the formula.

y/2a = 2ax/2a

x = y/ 2a

hope this was helpful,thanks

Sara and Collin's ages add up to 85. Sara is ten years older than foustimes

malfutka [58]

Answer:

Collin is 37.5 and Sara is 47.5

Step-by-step explanation:

s+c=85

c+10=s

(c+10)+c=85

2c+10=85

2c=75

c=37.5

s+(37.5)=85

s=47.5
