Answer:
1, 2 and 3
Step-by-step explanation:
Let
t -----> the number of hours the job takes
C(t) -----> the total cost for the service
we have

This is the equation of a line in slope intercept form
where
The slope m is equal to 
The y-intercept is the point (0,95) ---> The cost is $95 for the value of t equal zero (fee)
therefore
<u><em>The statements that are true</em></u>
1 a house call fee costs $95
2 the plumber charges $125 per hour
3 the number of hours the job takes is represented by t
Answer:
10 in
Step-by-step explanation:
Answer:
(2,1)
Step by step explanation:
Please find the attachment.
We have been given that line
is horizontal and passes through point (1,1). Line
is vertical and passes through point (2,2). We are asked to find point of intersection of line
and line
.
Line
is a horizontal line so y-coordinate will be 1 for any value of x. Line
is a vertical line, so x-coordinate will be 2 for any value of y.
Therefore, intersection point of both lines will include x-coordinate of line
and y-coordinate of line
that is (2,1).
Firstly , we need to draw diagram
we are given
opposite =300
adjacent =750
now, we can use tan formula

now, we can find x

we get

so,
angle of depression is 21.8 degree.....Answer
3.5 phone calls an hour
