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

olya-2409 [2.1K]

Answer:

The point lies barely outside of the circle

Step-by-step explanation:

Equation of a Circle

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

A box is filled with 3 yellow cards, 2 blue cards, and 7 brown cards. A card is chosen at random from the box. What is the proba

Otrada [13]

We need to find the probability of the card chosen at random is yellow or brown.

So, since there are 3 yellow cards and 7 brown cards, the total numbers of cards that are yellow or brown is:

$3+7=10$

Now, the probability that the chosen card is yellow or brown can be found by dividing the above value by the total number of cards in the box.

The total number of cards in the box is:

$3+7+2=12$

Thus, that probability is given by:

$\frac{10}{12}=\frac{10\div2}{12\div2}=\frac{5}{6}$

Therefore, the answer is:

$\frac{5}{6}$
