Radius is half of the diameter.
So because the area of a circle is A= pi • r^2, to find the radius first, we have to change the equation to solve for r. Now it is, r= square root of A/pi. We plug in 1134.1. (Look at pic)
The diameter is 38
The resulting equation if Becca isolated x² in the first equation and then substituted it into the second equation is (9-y²) / 25 - y²/36 = 1
<h3>Equation</h3>
x² + y² = 9
x²/25 - y²/36 = 1
From (1)
x² = 9 - y²
substitute x² = 9 - y² into (2)
x²/25 - y²/36 = 1
(9-y²) / 25 - y²/36 = 1
Therefore, the resulting equation is option C; (9-y²) / 25 - y²/36 = 1

Answer:

Step-by-step explanation:
step 1
Find the slope of the given line
we have

isolate the variable y

The slope of the given line is

step 2
Find the equation of the line that goes through the point (1,5) and is parallel to the given line
Remember that
If two lines are parallel then their slopes are equal
therefore
we have


substitute in the equation of a line in slope intercept form


solve for b

substitute

1) 29.74*60=1,784.4 miles per minute
1,784.4= 1,784 4/10=
1,784 2/5 miles per minute
2) 29.74-8.23= 21.51=21 51/100
3) ???
4) 21.76*60=1,305.6=1,305 6/10
