Find the center and the radius of the circle with the equation .
Simora [160]

We have been given an equation of circle x^2+2x+y^2-2y-14=0. We are asked to find the center and radius of the circle.

First of all, we will write equation of circle is standard form (x-h)^2+(y-k)^2=r^2, where center of circle is at point (h,k) and radius is r.

Let us complete the square for both x and y.

x^2+2x+y^2-2y-14+14=0+14

x^2+2x+y^2-2y=14

Adding half the square of coefficient of x and y term, we will get:

(\frac{2}{2})^2=1^2=1

(\frac{-2}{2})^2=(-1)^2=1

x^2+2x+1+y^2-2y+1=14+1+1

(x+1)^2+(y-1)^2=16

(x-(-1))^2+(y-1)^2=4^2

Therefore, the center of the circle is (-1,1) and radius is 4 units.

If 15% of x is 42, what is x?
Blizzard [7]

Answer:

x=280

Step-by-step explanation:

We have, 15% × x = 42

or,

15

100

× x = 42

Multiplying both sides by 100 and dividing both sides by 15,

we have x = 42 ×

100

15

x = 280

If you are using a calculator, simply enter 42×100÷15, which will give you the answer.
