Answer:
Step-by-step explanation:
Area of the specified region = Area of larger circle - Area of smaller circle
Larger circle:
r = 16 + 3 = 19 m
Area = πr²
=π * 19 * 19
= 361π m²
Smaller circle:
r = 16 m
Area = πr²
=π * 16 * 16
= 256π m²
Area of the specified region = 361π - 256π = 105π m²
To be perpendicular the product of the two slopes must equal -1.
2m/5=-1
2m=-5
m=-2.5
since y=mx+b we have so far
y=-2.5x+b, using point (-3,4) we can solve for b
4=-2.5(-3)+b
4=7.5+b
b=-3.5 so
y=-2.5x-3.5 We can multiply the whole equation by two so that the coefficients are integers...
2y=-5x-7 add 5x to both sides
5x-2y=-7
