Answer:
D
Step-by-step explanation:
Sector of Area=(theta/360)*pi*r^2
Sector of area=(135/360)*pi*19^2=(1083)/8 pi

Answer:
- 
Step-by-step explanation:
Calculate the slope m using the slope formula
m = 
with (x₁, y₁ ) = (0, - 4) and (x₂, y₂ ) = (1, 1) ← 2 points on the line
m = 
= 
= 5
Given a line with slope m then the slope of a line perpendicular to it is
= - 
= -
Answer:
55
Step-by-step explanation:
1+2+3+4+5+6+7+8+9+10
= 55
A line perpendicular to y = (-2/3)x + 5 has a slope of (+3/2).
Use the slope-intercept formula here, and find b:
y = mx + b becomes 1 = (3/2)(8) + b. Multiplying all terms by 2, we get
2 = 24 + 2b. Thus, 2b = -22, b = -11, and the equation of the line is y = (3/2)x - 11.
