Answer:

Surface area - 0.96, Volume - 0.064

Step-by-step explanation:

2/5- 0.40

For surface area, the equation is 6a^2

When you fill in the variable its

6(0.4)^2

follow pemdas, so you do the exponents first

(0.4)(0.4)

0.16

6(0.16)

0.96

The formula for volume is a^3

0.4^3

(0.4)(0.4)(0.4)

(0.16)(0.4)

0.064

Given that the average rate of change for y = f(x) over the interval [0,3] is −1, the average rate of change over the interval [

Answer:

Answer is 2

Step-by-step explanation:

We know that average rate of change of a function f(x) in the interval (a,b) is

$\frac{1}{b-a} \int\limits^a_b {f(x)} \, dx$

Using this we can say that

$\int\limits^0_3 {f(x)} \, dx =-1(3)=-3\\\int\limits^2_3 {f(x)} \, dx =5(1)=5\\\\\int\limits^2_6 {f(x)} \, dx =4(5)=20\\$

Using properties of integration we have

3 to 6 integral = 20-5 =15

0 to2 integral = -3=5 =-8

Thus integral form 0 to 6 would be = -8+15+5 = 12

Average rate of change form 0 to 6 = $\frac{12}{6} =2$
