Where does the point (6,2) lie on a circle centered at (7,8) with a radius of 6

olya-2409 [2.1K]

Answer:

<em>The point lies barely outside of the circle</em>

Step-by-step explanation:

<u>Equation of a Circle</u>

Given its center (h,k) and radius r, the equation of a circle is given by

$(x-h)^2+(y-k)^2=r^2$

The circle given in the question is centered at (7,8) and has a radius of 6, thus its equation is

$(x-7)^2+(y-8)^2=6^2$

$(x-7)^2+(y-8)^2=36$

To find out if a point (a,b) is outside or inside the circle area, the following conditions apply.

if $(a-7)^2+(b-8)^2>36$ then the point lies outside of the circle area

if $(a-7)^2+(b-8)^2$ then the point lies inside of the circle area

Let's use the point as given (6,2)

$(6-7)^2+(2-8)^2=1+36=37$

Thus the point lies barely outside of the circle

scoray [572]

Answer:

$1545.65.

Step-by-step explanation:

We have been given that Victor has a credit card with an APR of 13.66%, compounded monthly. He currently owes a balance of $1,349.34.

To solve our given problem we will use compound interest formula.

$A=P(1+\frac{r}{n})^{nt}$ , where,

A = Final amount after t years,

P = Principal amount,

r = Interest rate in decimal form,

n = Number of times interest is compounded per year,

t = Time in years.

Let us convert our given interest rate in decimal form. $13.66=\frac{13.66}{100}=0.1366$

Upon substituting our given values in compound interest formula we will get,

$A=1,349.34(1+\frac{0.1366}{12})^{12*1$

$A=1,349.34(1+0.011383333)^{12$

$A=1.349.34(1.011383333)$

$A=1,349.34*1.145485275522$

$A=1,545.64910167397$ ≈ $ $1545.65$

Therefore, Victor will owe an amount of $1545.65 after one year.
