Complete question :
A circular swimming pool has a radius of 28 ft. There is a path all around the pool that is 4 ft wide. A fence is going to be built around the outside edge of the pool path.
About how many feet of fencing are needed to go around the pool path
Answer:
201 feets
Step-by-step explanation:
The Circumference of a circle, C :
C = 2 * pi * r
r = Radius ; pi = 3.14
The entire Radius = pool radius + pathnaroind the pool = 28 + 4 = 32
Hence, the Circumference, which gives the value of fencing required is :
C = 2 * 3.14 * 32
C = 200.96 ft
C = 201 feets
<span>-7+9= -9 + 7 is false
cause
-7 + 9 = 2
-9 + 7 = -2
2 can't equal -2</span>
Answer:
first you have to change the form of the equation, then you have to graph the y-intercept and the x-intercept and graph the slope

Answer:
Option A) y = -2x + 15
Step-by-step explanation:
step 1
Find the slope of the line perpendicular to the given line
we know that
If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is equal to -1)
The equation of the given line is

so
The slope of the given line is 
therefore
The slope of the line perpendicular to the given line is

step 2
Find the equation of the perpendicular line in point slope form

we have


substitute
---> equation in point slope form
Convert to slope intercept form
