Answer:
72π feet
Step-by-step explanation:
circumference of circle= 2πr
Diameter= 2(radius)
radius of circle
= 72 ÷2
= 36 ft
Circumference
= 2(π)(36)
= 72π ft
Answer: look at pic
Step-by-step explanation:
y=mx+b
m:slope
b:y-intercept
m=-1 (slope) given in the question
y=-1x+b
Plug in the given point (-1,-4) then solve for b
-4=-1(-1)+b
b=-5
y=-x-5
then using the x-intercept and y-intercept you could graph the line
y-intercept = b = -5 (0,-5)
x-intercept (plug in y=0)
0=-x-5
x=-5 (-5,0)
Answer:
k=-9
Step-by-step explanation:
198 - 13k = 7(-9k-36)
198 - 13k = -63k-252
63k-13k= -252 - 198
50k= -450
k=-9
