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 <em>x </em>= 0 to <em>x </em>= 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 <em>x</em> = 0, our function evaluates to:

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

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

For our second endpoint at <em>x</em> = 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

A company tests two new products to make sure they last for more than a year. Product 1 had 950 out of 1,000 test items last for
zheka24 [161]

Answer:

product one; it has a higher success rate

Step-by-step explanation:

to find out which has a higher rate of success we can find out their percentage of success

we can divide their success amounts by test amounts

950 / 1000 = 95/100 = 95%

150/200 = 75/100 = 75%

product 1 has a higher success rate

These two area models represent 2323 and 6969. Choose the equation that shows why 2323 and 6969 are equivalent.
grandymaker [24]
Well lets lay it out


     2323      6969
 
     first get 2323 and try its multiples.

     2323 x 2 = 4646
     2323 x 3 = 6969
  
   so what 2323 and 6969 have in common are the multiple 3

Answer: they are equivalent because they can be divided into each other. HOPE I  HELPED!! :P <span />
