give the equation for a circle with the given center and radius.
center at (-1, 3), radius = 4
a. (x+3)2+(y−1)2=4
b. (x−3)2+(y+1)2=4
c. (x−1)2+(y+3)2=16
d. (x+1)2+(y−3)2=16

D.

Step-by-step explanation:

We are asked to write equation of a circle whose center is at point and whose radius is 4 units.

We know that equation of a circle is standard form is in format , where is the center of circle.

Upon substituting , and in the standard form of circle, we will get:

Therefore, our required equation would be and option D is the correct choice.

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
