Answer:

Step-by-step explanation:
Given
Perpendicular to 
Pass through 
Required
Determine the line equation
First, we need to determine the slope of 
An equation is of the form:

Where

In this case:

Next, we determine the slope of the second line.
Since both lines are perpendicular, the second line has a slope of:



Since this line passes through (-2,2); The equation is calculated as thus:

Where

This gives:



Add 2 to both sides


Answer:
25/19
Step-by-step explanation:
100/76 we can divide both the numerator and denominator by 4 to get 25/19. The decimal answer would be around 1.32.
C = 2πr
C = 2(3.14)(0.8)
C = 2(2.512)
C = 5.024 m
The answer is C.
The fourth and first one. :)
