Answer:

3 minutes

5 minutes.

Step-by-step explanation:

It is given that, Amelia can wash 8 plates in 24 minutes.

So, if this rate remains constant then 1 plate will be washed in \frac{24}{8} = 3 minutes.

Again, it is given that, Amelia bakes 12 cookies in 60 minutes.

So, if this rate also remains constant then she will bake 1 cookie in \frac{60}{12} = 5 minutes. ( Answer )

How to find the average rate of change of a function
ollegr [7]

ANSWER

Average Rate of Change

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

EXPLANATION

To find the average rate of change of y=f(x) from x=a to x=b means finding the slope of the secant line joining the points

(a,f(a)) and (b,f(b))

The slope of the secant line joining these points is

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

This gives the average rate of change of the function.

Answer:  tan(V)=2.92

Step-by-step explanation:

For this exercise you need to remember the following Trigonometric Identity:

tan\alpha =\frac{opposite}{adjacent}

You must observe the figure given in the exercise.

You can notice that the given triangle UVW is a Right triangle (because it has an angle that measures 90 degrees).

So, you can identify in the figure that:

\alpha =V\\\\opposite=UW=35\\\\adjacent=VW=12

Knowing these values, you can substitute them into  tan\alpha =\frac{opposite}{adjacent}:

tan(V)=\frac{35}{12}

Now you must evaluate:

tan(V)=2.916

Finally, rounding to the nearest hundreth, you get:

tan(V)=2.92
