Formula for the perimeter of a quarter circle: C = ((pi x 2r) / 4) + 2r
C = ((3.14 x 18) / 4) + 18
C = (56.52 / 4) + 18
C = 14.13 + 18
C = 32.13 miles
Hope this helps! :)
Y=4x+4
I think this is it u just have to simplify to get it to y=mx+b
Answer:
The values of 'x' are -1.2, 0, 0,
or
.
Step-by-step explanation:
Given:
The equation to solve is given as:

Factoring
from all the terms, we get:

Now, rearranging the terms, we get:

Now, factoring
from the first two terms and 6 from the last two terms, we get:

Now, equating each factor to 0 and solving for 'x', we get:

There are 3 real values and 2 imaginary values. The value of 'x' as 0 is repeated twice.
Therefore, the values of 'x' are -1.2, 0, 0,
or
.
Answer:
y=2x-8
Step-by-step explanation:
y-y1=m(x-x1)
y-4=2(x-6)
y=2x-12+4
y=2x-8
