Answer:
The average rate of change for the given function, from x = −3 to x = 7 will be:
Step-by-step explanation:
Given the table
x f(x)
-3 50
3 10
7 0
As the interval is from x = -3 to x = 7.
so
at x₁ = -3, f(x₁) = 50
at x₂ = 7, f(x₂) = 0
Using the formula to determine the average rate of change at which the total cost increases will be:
Average rate = [f(x₂) - f(x₁)] / [ x₂ - x₁]
= [0 - 50] / [7-(-3)]
= [-50] / [7+3]
= -50 / 10
= -5
Therefore, the average rate of change for the given function, from x = −3 to x = 7 will be:
Answer: 28.
Step-by-step explanation:
The median of a data set is defined as the middle value of a data set.
For instance, the median of the data set [4, 7, 8] would be 7 because it is the "middle value".
You can find this by sorting the numbers by smallest to largest:
2, 9, 15, 16, 21, 24, 28, 32, 34, 35, 37, 39, 40
There are 13 numbers in the set, so you can exclude the first 6 and last 6 numbers from the set to get your median, 28.
distributive because you are distributing the outside number into the parentheses
Answer:
21870 km^2
Step-by-step explanation:
Area of sector=1/2r^2(theta)
Where r=18 km and theta=135
Area of sector=1/2(18)^2(135)
=1/2(324)(135)
=1/2(43740)
=21870 km^2
