Answer: y = 31
Step-by-step explanation:
The equation of a line is y = mx+b
Plugging in the values, we get
y = 4*8 + (-1)
y = 32-1
y = 31
Answer:
The distance you are from the base of plateau = 
Step-by-step explanation:
Given:
Height of plateau = 70 m
Angle of elevation to the top of plateau = 35°
To find the distance you are from the base of plateau.
We will construct a triangle ABC to model the given situation. The triangle would be a right triangle for which we know an angle and its opposite side. We need to find the adjacent side of the triangle.
We will apply trigonometric ratio to find the adjacent side.

where
represents the angle of reference.
Plugging in the values from the triangle.


Multiplying both sides by AC.


Dividing both sides by 

∴ 
The distance you are from the base of plateau = 
Answer:
The rate of change is $15/day
Step-by-step explanation:
The rate of change, using the points (1,60) and (5,120)
m= (y2-y1) / (x2-x1)
= (120-60)/ (5-1)
= 60/4
= 15
The rate of change is $15/day
Answer:
Step-by-step explanation:
No, because the lines are in the same plane.
