If f (x) = x^2 - 4 what is the average rate of change from x = 3 to x = 5?

Mathematics

Natasha2012 [34]3 years ago
5 0

Answer:

The average rate of change is 8

Step-by-step explanation:

Mathematically, we have the average rate of change over a given interval as;

f(b) - f(a)/b-a

Where the interval is [a,b]

With respect to this question, a = 3 and b = 5

f(a) = f(3) = 3^2 - 4 = 9-4 = 5

f(b) = f(5) = 5^2 - 4 = 25-4 = 21

Thus, the average rate of change over the intervals will be;

(21-5)/(5-3) = 16/2 = 8

a beach ball has a diameter of 10 inches. What is the volume of air contained inside the beach ball? Use 3.14 for pi. Round your
erastova [34]

Answer:

A beach ball is a sphere, so we will need to know how to find the volume of a

sphere. V = 4Pi * (r ^ 3 / 3)

We have the diameter, but not the radius. To find the radius, it is half of the

diameter.

10÷2=5 Now let's plug it in.

4T(5³/3) Let's solve.

4pi = 12.56

5³= 125

125÷3= 41.67 (repeating 6) 41.67x12.56=523.3752

523.33 cubic inches is the volume of

air contained inside the beach ball. The reason I picked that answer is because a repeating 6. So we should expect for

we rounded up to 41.67, when there was

the answer to be a couple decimals lower

from the answer we got. Tell me if this helps!!

A line containing the points (4, y) and (-3, 2) has a slope of 3/2.
Sonbull [250]

Answer:

y=14.5

Step-by-step explanation:

A slope of 3/2 means that for every unit it moves to the right, it will move 1.5 units up. The x of 4 is 7 more than the -3 of our other point. 7*1.5=12.5, and 12.5+2=14.5.
