Paralell lines have the same slope
perpendicular lines have slopes that multiply to get -1
neither is niegher
so
y=mx+b
m=slope
x=y+2
minus 2
x-2=y
y=x-2
y=1x-2
slope is 1
y=x+3
y=1x+3
1=1
they are paralell
Answer:
The answer is 16.
Step-by-step explanation:
The Radius is half the diameter.
Answer:
in terms of .
Step-by-step explanation:
A 360 degree rotating sprinkler will water a full circular region of the lawn.
The area of this circular region is calculated using the formula:
where r=11 feet is the radius of the circular region covered.
We substitute the value of the radius into the formula to get:
in terms of .
This is approximately to the nearest tenth
We are given the expression sin (sin-1 (X) + cos-1 (y)). We use the associative property to distribute the sine function. sin (sin-1 (x)) is equal to x. cos-1 (y) is equal to beta, the other angle besides alpha. sin beta is also equal to x which means the simplified term is 2x. This makes sense because sin-1 x = cos-1 y
