Answer:
99.0 in²
Step-by-step explanation:
The area (A) of the sector of the circle is calculated as
A = area of circle × fraction of circle
= πr² × 
( where r is the radius )
Here r = 9, thus
A = π × 9² × 
= 81π × ≈ 99.0 in²
The equation would be y = -5/2x - 14. Since the slope and a coordinate pair was given, I used point slope form to figure out the equation.
Work:
y - 6 = -5/2 (x+8)
y - 6 = -5/2x - 20
+ 6 +6
______________
y = -5/2x - 14
Just take a calculator and divide 4 by 10 exactly how you see it. Or just divide it like you normally would any number on paper. 0.4 is your answer.
1// Flip the second fraction [RECIPROCAL]
2// Multiply bottom of fraction by whole number, add 1 to bottom of whole number.
3// Simplify.
Answer:
C7,3=7!( 3!)( 7−3)!= 7! I think tell me if I'm wrong?
