Answer:
The average rate of change is of -13.
Step-by-step explanation:
Average rate of change:
The average rate of change of a function in an interval [a,b] is given by:
![A = \frac{f(b) - f(a)}{b - a}](https://tex.z-dn.net/?f=A%20%3D%20%5Cfrac%7Bf%28b%29%20-%20f%28a%29%7D%7Bb%20-%20a%7D)
In this question:
Between 2 and 6. So
![f(6) = -5(6) - 6^2 = -30 - 36 = -66](https://tex.z-dn.net/?f=f%286%29%20%3D%20-5%286%29%20-%206%5E2%20%3D%20-30%20-%2036%20%3D%20-66)
![f(2) = -5(2) - 2^2 = -10 - 4 = -14](https://tex.z-dn.net/?f=f%282%29%20%3D%20-5%282%29%20-%202%5E2%20%3D%20-10%20-%204%20%3D%20-14)
![A = \frac{-66 - (-14)}{6 - 2} = \frac{-66 + 14}{4} = \frac{-52}{4} = -13](https://tex.z-dn.net/?f=A%20%3D%20%5Cfrac%7B-66%20-%20%28-14%29%7D%7B6%20-%202%7D%20%3D%20%5Cfrac%7B-66%20%2B%2014%7D%7B4%7D%20%3D%20%5Cfrac%7B-52%7D%7B4%7D%20%3D%20-13)
The average rate of change is of -13.
Answer:
65
Step-by-step explanation:
55 + 65 + 57 = 177
there are more factors, but I found this one the quickest.
hope this helps!
Answer:
The rates are equal
Step-by-step explanation:
To see if the rates are equal, divide both of the units by the number of minutes:
60/3
= 20
80/4
= 20
This means both rates are equal, since we got 20 for both of them
This means the rate is 20 units per 1 minute, for both rates.
So, the rates are equal.
Answer:
random
Step-by-step explanation:
each has a random, equal chance of being selected
h(x) = f(x) + g(x)
= 600 (1.14)^x + 450(1.14)^x
1050 1.14^x
Choice A
