Answer:
Bonsoir,
f'(-5)=-4/3
f'(-1) =3/4
Step-by-step explanation:
f'(-5) = ?
2 points : (-6,9) and (-3,5)
f'(-5)=(9-5)/(-6-(-3))=-4/3
f'(-1) = ?
2 points : (-3,5) and (1,8)
f'(-1)=(5-8)/(-3-1)=3/4
The lines are perpendicular
The width of the walkaway be 4 feet.
<h3>What is Discriminant Formula?</h3>
The discriminant formula is used to determine the nature of the roots of a quadratic equation. The discriminant of a quadratic equation is D =
If D > 0, then the equation has two real distinct roots.
If D = 0, then the equation has only one real root.
Given that:
also, area of walkaway = 464 square feet.
So,
Using Discriminant method,
a=4, b=100, c=-464
w=
w=
So,
Hence the width of the walkaway be 4 feet.

Answer:
(240ft) sorry it took me a sec :P
Step-by-step explanation:
Answer:
c=2r
divide both sides by 2
c/2=r
if you forgot the pi
c=2pir
divide by 2pi
c/(2pi)=r
