The answer to your question is 177,251.28571529
Perpendicular = opposite sign and reciprocal slope
-4 slope turns into 1/4
Y = 1/4x + b
11 = 1/4(-16) + b
11 = -4 + b, b = 15
Solution: y = 1/4x + 15
Answer:
a
Step-by-step explanation:
The equation of a proportional relationship is
y = kx ← k is the constant of proportionality
Divide both sides by x
= k
To find k use any ordered pair from the table
Using (2, 
) , then
k = 
= 2 × 
= 
Answer:
1/2
Step-by-step explanation:
4 of the 8 marbles are blue:
4/8 = 1/2
Let's say the original radius was "r", so the circumference is 2πr and the area is πr².
Now when you double the radius, the you get a new circle with radius 2r, circumference 2π(2r) = 4πr, and area π(2r)² = 4πr².
