y - y₁ = m(x - x₁)
y - 2 = -1¹/₄(x - 5)
y - 2 = -1¹/₄(x) + 1¹/₄(5)
y - 2 = -1¹/₄x + 6¹/₄
+ 2 + 2
y = -1¹/₄x + 8¹/₄
When Maggie hooks her dog up to a rope that is staked in the yard, the dog can walk a distance of about 76 feet along the circum
ference. To the nearest tenth, what is the length of the rope?

Answer: 12.1 ft
Step-by-step explanation:
Hi, to answer this we have to apply the circumference formula:
C= 2πr
Where:
C = circumference ( in this case is 76, since the dog can walk a distance of about 76 feet along the circumference.)
r = radius. (In this case the radius is the length of the rope, because the stake is in the center of the circumference)
Replacing with the values given and solving for "r":
76 = 2πr
76 /( 2π)= 12.0957= 12.1 ft

Minus z both sides
0=x^2+wx+z
we can use quadratic formula or manually complete the square
let's use quadratic
for
0=ax^2+bx+c
given
0=1x^2+wx-z
a=1
b=w
c=-z
