1. A circle with center (-5, 2) is tangent to the y-axis. What is the radius of the circle? What is the equation of the circle?
Bess [88]

Answer:

Step-by-step explanation:

1)  The center lies on the vertical line x = -5 and the the circle is tangent to (touches in one place only) the y-axis.  Thus, the radius is 5.

2)  Starting with (x - h)^2 + (y - k)^2 = r^2 and comparing this to the given

                     (x - 4)^2 + (y + 3)^2 = 6^2

we see that h = 4, k = -3 and r = 6.  The center is at (4, -3) and the radius is 6.

3)  Notice that A and B have the same x-coordinate, x = 15.  The center of the circle is thus (15, -2), where that -2 is the halfway point between the two given points in the vertical direction.   Arbitrarily choose A(15, 4) as one point on the circle.  Then the equation of this circle is

(x - 4)^2 + (y + 3)^2 = r^2 = 6^2, where the 6 is one half of the vertical distance between A(15, 4) and B(15, -8) (which is 12).

Solve the Fahrenheit equation for Celsius
horrorfan [7]
The first step you should do is subtract 32 from both sides so your answer will turn out like this -

F = (9/5) C + 32
- 
F - 32 = (9/5)

Then we will multiply both sides by 5. 

5 ( F - 32 ) = 9 C

Divide both sides by 9 to isolate C.

(5/9)  ( F - 32 ) = C

So the answer is :

C = (5/9) ( F - 32 )

Hope this helps :)
