Answer:
Step-by-step explanation:
The mean (or average) of a set of numbers can be found with the following formula:
For this problem, we have five numbers, so we add them together and divide by 5:
The answer is 600, I got this by multiplying the two numbers
Answer:
The Answer to this equation Y = 32
Step-by-step explanation:
Answer: Choice D
(a-e)/f
=======================================
Explanation:
Points D and B are at locations (e,f) and (a,0) respectively.
Find the slope of line DB to get
m = (y2-y1)/(x2-x1)
m = (0-f)/(a-e)
m = -f/(a-e)
This is the slope of line DB. We want the perpendicular slope to this line. So we'll flip the fraction to get -(a-e)/f and then flip the sign from negative to positive. That leads to the final answer (a-e)/f.
Another example would be an original slope of -2/5 has a perpendicular slope of 5/2. Notice how the two slopes -2/5 and 5/2 multiply to -1. This is true of any pair of perpendicular lines where neither line is vertical.
