Write the equation of each circle given its center and a point P that it passes through

Elan Coil [88]

Answer:

$(x-1)^2+(y-1)^2=37.$

Step-by-step explanation:

If the center of the circle is (1,1) and the circle passes through the point (2,-5), then the radius of the circle is

$r=\sqrt{(1-2)^2+(1-(-5))^2}=\sqrt{1+36}=\sqrt{37}.$

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

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

In your case, the equation is

$(x-1)^2+(y-1)^2=37.$

Edna decided to purchase a $15,000 MSRP vehicle at a 5% interest rate for 3 years. The dealership offered her a $1500 cash-back

Ad libitum [116K]

P = A/D, Where P = Monthly payments, A = Total amount owed = 15,000-1,500 = $13,500,

$D= \frac{( 1+ \frac{r}{12} )^{nt} -1}{ \frac{r}{12} (1+ \frac{r}{12}) ^{nt} }$

r = 5% = 0.05, nt = 12*3 = 36

Therefore,
D = $\frac{(1+ 0.05/12)^{36}-1 }{(0.05/12)(1+0.05/12)^{36} }$ = 33.37

Then,

P = 13,500/44.37 = $404.61
The correct answer is c.
