Answer:

the average rate of change is 4.

Step-by-step explanation:

Find the average rate of change of f(x)=x^2 on the interval [1,3].

The average rate of change of f(x) on the interval [a,b] is f(b)−f(a)/b−a.

We have that a=1, b=3, f(x)=x^2.

Thus, f(b)−f(a)/b−a=((3))^2−(((1))^2)/3−(1) = 4.

Find the surface area
iragen [17]

Answer:

The surface area is 302 in²

Step-by-step explanation:

Known :

Long (l) = 11 in

Weight (w) = 6 in

Height (h) = 5 in

Asked :

Surface Area (Sa) = ...?

Answer :

Formula :

= 2(l.w) + 2(l.h) + 2(w.h)

= \boxed{2 (l.w + l.h + w.h)}

= 2 (11×6 + 11×5 + 6×5)

= 2 (66 + 55 + 30)

= 2 × 151

= <u>3</u><u>0</u><u>2</u><u> </u><u>in²</u>

So, the surface area is 302 in²

How many solutions are there to the equation below?
Elza [17]

Answer:

no solution

Step-by-step explanation:

heres why:

Let's solve your equation step-by-step.

4x−9(x+1)=20−5x

Step 1: Simplify both sides of the equation.

4x−9(x+1)=20−5x

4x+(−9)(x)+(−9)(1)=20+−5x(Distribute)

4x+−9x+−9=20+−5x

(4x+−9x)+(−9)=−5x+20(Combine Like Terms)

−5x+−9=−5x+20

−5x−9=−5x+20

Step 2: Add 5x to both sides.

−5x−9+5x=−5x+20+5x

−9=20

Step 3: Add 9 to both sides.

−9+9=20+9

0=29

so there are no solution
