The average rate of change is 4.
<h3>What is function?</h3>
An expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
The rate of change in interval [0, 2]
r=[h(2)-h(0)]/2
h(2)=(2)²+2(2)-6
h(2)=4+4-6
h(2)=2
h(0)=(0)²+2(0)-6
h(0)=0+0-6
h(0)=-6
So, r=[h(2)-h(0)]/2
r=[2-(-6)]/2
r=(8)/2
r=4

Answer: 26 dollars
Step-by-step explanation:
The owner needs to consider that:
To measure the risk she can multiply the probability of an event to happen (P)* the impact (I) (in this case the impact is the cost).
All these eventes can be considered as independent between each other (no correlation), so you can add their P*I.
In this case:
P1*I1= 1%*550=5.5
P2*I2=6%*150=9
P3*I3=15%*100=15
So, the expected value of what she may spend for repairng is = P1*I1+P2*I2+P3*I3= 5.5+9+15= 29.5
She shoould not spend more than 29.5 dollars, otherwise, she will spend more in the surge supresor than in expected reapring value
You would use PEMDAS so that means you would start by multiplying 3 with the parentheses 3(2+6d) on both sides then you would combine like terms so you would add 18d+18d. Then you would subtract 6- -5 on both sides then solve for a one-step equation
3(2+6d)-5=3(2+6d)-5
6+18d-5=6+18d-5
6+36d-5=6-5
1+36d=1
-1. -1
36d/36. 0/30
D=0
