x^5 is your answer because you add exponents when they are not in separate paretheses.

Think: x^2 • x^3 = x^(2+3). Yes, add the exponents, while keeping the base, 3.

Thus, x^2 • x^3 = x^5.

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 [

Svet_ta [14]

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 = $\frac{12}{6} =2$

Simplify the expression 6h + (-8.1d) - 13 + 5d - 2.4h

Alisiya [41]

Answer:

3.6h - 3.1d + 13

Step-by-step explanation:

Combine like terms. Like terms have same variables.

Like terms : (i) 6h and (-2.4h) (ii) -8.1d and 5d

6h + (-8.1d) - 13 + 5d - 2.4h = 6h - 2.4h + (-8.1d) + 5d - 13

= (6 - 2.4)h + (-8.1 + 5)d - 13

= 3.6h - 3.1d + 13
