A soccer ball is kicked and travels 25 meters to the north in 2.5 seconds. At what velocity is the ball traveling?

algol [13]

It would be 10m.
If you divide 25 by 2.5 you get 10, and since we’re using velocity, that’s what we would do.

What are two numbers that can be multiplied together to equal -30 but also the same two numbers add up to -5

Orlov [11]

I’d say -1 but you probably need a better answer so I’d say -2.5

The cost of a floral bouquet after a discount is applied is represented by the function below, where x represents the number of

galina1969 [7]

The average rate of change over the interval $(12,24)$ is 2.17

Explanation:

Given that the cost of a floral bouquet after a discount is given by the function $f(x)=2.17x-10.00$

We need to determine the average rate of change over the interval $(12,24)$

The average rate of change can be determined using the formula,

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

where $a=12$ and $b=24$

Substituting the value of a and b in the function, we get,

$f(12)=2.17(12)-10.00$

$=26.04-10.00$

$=16.04$

$f(24)=2.17(24)-10.00$

$=52.08-10.00$

$=42.08$

Hence, substituting these values in the formula, we get,

$\frac{f(b)-f(a)}{b-a}=\frac{42.08-16.04}{24-12}$

Simplifying, we get,

$\frac{f(b)-f(a)}{b-a}=\frac{26.04}{12}$

Dividing, we have,

$\frac{f(b)-f(a)}{b-a}=2.17$

Thus, the average rate of change over the interval $(12,24)$ is 2.17
