What is the average rate of change for the function f(x)=3^x-9 9 less than or equal to x less than or equal to 11

sattari [20]

The average rate of change of a function $f(x)$ in the interval $[a,b]$ is defined as

$A(a,b,f) = \dfrac{f(b)-f(a)}{b-a}$

So, in your case, we have

$A(9,11,3^x-9) = \dfrac{(3^{11}-9)-(3^9-9)}{11-9} = \dfrac{3^{11}-3^9-9+9}{2} = \dfrac{157464}{2}=78732$

Angie is going to varnish the floor. Continued on other side of the page She needs 1 litre of varnish for 5 m2 of floor. There a

nirvana33 [79]

Answer:

No, she doesn't have enough varnish for all the floors.

Step-by-step explanation:

Area of the floor, A= 10x6-5x2=50 $m^2$

Since 5 m^2 required 1 liter of varnish.

So, the amount of varnish required for 1 $m^2$ = 1/5= 0.2 liters.

The amount of varnish required for 50 $m^2$ = 0.2X50=10 liters.

Now, as 1 tin has 2.5 liters of varnish.

So, the total amount of varnish available = 3x2.5=7.5 liters, which is less than the total requirement.

Hence, she doesn't have enough varnish for all the floors.
