Answer:
<em>The average rate of change is $25.5 per hour, option B.</em>
Step-by-step explanation:
<u>Average Rate of Change
</u>
When we are explicitly given some function C(x), we sometimes need to know the rate of change of C when x goes from 
to 
. It can be computed as the slope of a line
.
The provided function is
We are required to compute the average rate of change between the points
Let's compute
The average rate of change is $25.5 per hour, option B.
Answer:
1. 156 2. 84 3. 74
Step-by-step explanation:
1. b x h. 8 x 8 is every side on the square so one side is 64 and the one behind it is 64 also which is 128 and since that is the case with the other sides its 128 + 128 = 156
2. 1/2 x b x h = 1/2 x 4 x 3 = 6 x 2 because of the side behind it that is the same = 12. 6 x 5 = 30; 6 x 4 = 24; 6 x 3 = 18. 12 + 30 + 24 + 18 = 84
3. b x h. 2.5 x 2 = 5 x 2 because of the other side = 10; 7 x 2.5 = 17.5 x 2 = 35; 7 x 2 = 14 x 2 = 28. 10 + 35 + 28 = 76
Answer:
i think it's A.) 5.5
Step-by-step explanation:
A right triangle has 90°
Given: 15 and 20
15 + 20 = 35
90 - 35 = 55
55 is the missing angle
Round to the nearest tenth: 55 ÷ 10 = 5.5
