Answer:

Step-by-step explanation:

A radius to the tangent point always forms a right angle with the tangent.

m∠MNP = 90° so we can use Pythagorean theorem:

$MN^2+NP^2=MP^2\\\\MN^2+48^2=50^2\\\\MN^2+2304=2500\\\\MN^2=196\\\\MN=\sqrt{196}\\\\MN=14\,ft$

The circle below is centered at the point (4,3) and has a radius of length 5.

Lilit [14]

Answer:

B. (x-4)^2 + (y - 3)^2 = 5^2

Step-by-step explanation:

The equation for a circle is given by

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

where (h,k) is the center and r is the radius

We have a center of (4,3) and a radius of 5

(x-4)^2 + (y-3) ^2 = 5^2

Tanya prepared 4 different letters to be sent to 4 different addresses. For each letter, she prepared an envelope with its corre

Ad libitum [116K]

Answer:

1/3 is the answer.

Step-by-step explanation:

Tanya prepared 4 different letters to be sent to 4 different addresses.

To solve this we can do the following:

The probability that the 1st letter is in the right envelope is = $\frac{1}{4}$

The probability that the 2nd letter is in the wrong envelope is = $\frac{2}{3}$

The probability that the 3rd letter is in the wrong envelope is = $\frac{1}{2}$

The probability that the 4th letter is in the wrong envelope is = 1

So, the answer becomes: $\frac{1}{4}\times \frac{2}{3}\times \frac{1}{2}\times1$ = $\frac{1}{12}$

As we need 4 correct letters in the envelope, we will multiply by 4:

$\frac{1}{12}\times4=\frac{1}{3}$

The point (-3,3) lies on a circle. What is the length of the radius of this circle if the center is located at (10,6) ?

Amiraneli [1.4K]

The radius is from center to point on a circle.
So your task is count distance between two points: S(10,6) and A(-3,3).
Distance between two points A(x1, y1) and B(x2, y2) count from this formula:
$|AB|=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\ \\ \hbox{So:} \\ \\ r=|SA|=\sqrt{(-3-10)^2+(3-6)^2}=\sqrt{(-13)^2+(-3)^2}=\sqrt{169+9}= \\ r= \sqrt{178}$
