PSF: y - y₁ = m(x - x₁)
Standard Form: ax + by = c
Point Slope Form Standard Form
1). y - 3 = -4(x + 8) 2). y = -4x - 29
y - 3 = -4x - 32 + 4x + 4x
+ 3 + 3 ---------------------------------
----------------------------- 4x + y = -29
y = =4x - 29
The area of the circle can be calculated with the following formula
First let's find the radius
The answer would be 200.96 square yards

Answer:
See below.
Step-by-step explanation:
sin2x-tanx
= 2sinx cosx - sinx/cos
= (2sinx cos^2x - sin x) / cos x
= sinx ( 2 cos^2x - 1 ) / cos x
Now sin x / cos x = tanx and 2 cos^2 x - 1 = cos2x
so this simplifies to cos2x tan x.
