blondinia [14]3 years ago
5 0

The equation of a circle with center (x_0,y_0) and radius r is

(x-x_0)^2+(y-y_0)^2=r^2

In your case,

x_0=3,\quad y_0=-2,\quad r=3

Plug these values into the generic formula and you'll get your equation.

Two cars leave Denver at the same time and travel in opposite directions. One car travels 10 mi/h faster than the other car. The
MaRussiya [10]
The speed of one car is 'S'.  The speed of the other car is (S + 10).

In 5 hours, the first car travels (5S) miles, and the other car travels  5(S + 10) miles.

Since they're going in opposite directions, the distance between them at any time
is the sum of the distance that each one has traveled.

500 = (5S) + 5(S + 10)

500 = 5S  +  5S + 50

500 = 10S + 50

Subtract 50 from each side:

450 = 10S

Divide each side by 10

S = <u>45</u>

S + 10 = <u>55</u>

Can anyone help me with this
Natalka [10]

F(x) = 2x and G(x) = x^2 + 2

(G - F)(x) just means we subtract the functions from each other.

x^2 + 2 - 2x

Let's rearrange the expression

x^2 - 2x + 2
