Answer:
A. y=2x-9
B. 
Step-by-step explanation:
A. Parallel lines have the same slope. That means the line y=2x+3 has the same slope as any line parallel to it. So the slope is 2.
Using m=2, substitute it and (4,-1) into the point slope form and simplify to find the y-intercept.
B. Perpendicular lines have slopes which are negative reciprocals of each other. The slope of the line y=2x+3 is 2. The slope perpendicular to it is -1/2.
Using m=-1/2, substitute it and (4,-1) into the point slope form and simplify to find the y-intercept.
Answer: try it yourself
Step-by-step explanation:
(F/G)2-H; just simplify it.
12,548:9( you can’t simplify this ratio)
62,547 divided by 7 = 8,935.28571
5127 divided by 25 = 205.08
Answer:
The distance between the tree and the tower is 18.48 meters.
Step-by-step explanation:
We are given the following information in the question:
Height of tower = 30 m
Height of man = 2 m
Angle of depression = 30 degrees
We have to find the distance between the tree and the tower.
The attached image shows the scenario.
Formula:
Thus, the distance between the tree and the tower is 18.48 meters.
