Answer:
D
Step-by-step explanation:
Okay, so a general rule for finding perpendicular lines in the form of y = mx + b is y = (-1/m) + b.
First, let's ignore b (-7) because we're going to find that later.
A perpendicular line to y = 4x + b is y = -1/4x + b.
Alright, so now let's plug in the values. They are in the form of (x,y), so let's plug them in accordingly.
3 = -1/4(4) + b
3 = -1 + b
b = 4
y = -1/4x + 4
So a line perpendicular to y = 4x - 7 is y = -1/4x + 4.

Answer:
1) B
2) C
3) B
Step-by-step explanation:
Radius = D/2 = 7/2 × 2 = 7/4
Circumference = pi × D
= 7/2 pi
7/2 × 3.14 = 10.99
Approximately 11
