ad-work [718]

Answer:

Ashanti and Landry will for 7 hours to wash 56 cars

Step-by-step explanation:

* Lets explain how to solve the problem

- When to people work together to finish a job, we multiply the rate of

each by the time and add them,then equate the answer by the job

- Lets do that with Ashanti and Landry

- If Ashanti can wash 3 cars per hour

∴ The rate of Ashanti is 3 car per hour

- If Landry can wash 5 cars per hour

∴ The rate of Landry is 5 car per hour

- When they work together they will wash 56 cars

∵ They work together then they will work same amount of time

- Let the amount of time they will work is t

∵ Ashanti and Landry will work together for t hours to wash 56 cars

∴ 3t + 5t = 56

∴ 8t = 56

- Divide both sides by 8

∴ t = 7

∵ t represents the time they will work together

* Ashanti and Landry will for 7 hours to wash 56 cars

The table below shows the function f.

Dmitriy789 [7]

Answer:

A. 11

Step-by-step explanation:

The average rate of change of the given function over the interval [2,6] is simply the slope of the secant line connecting the point (2,f(2)) and (6,f(6)).

This implies that, the average rate of change over [2,6]

$=\frac{f(6)-f(2)}{6-2}$

$=\frac{f(6)-f(2)}{4}$

From the table f(6)=71

Since we want the average rate of change to be 15, we have;

$15=\frac{71-f(2)}{4}$

This implies that;

$4\times15=71-f(2)$

$60=71-f(2)$

$60-71=-f(2)$

$-11=-f(2)$

$11=f(2)$

The correct choice is A.
