Find the equation of a circle with a center at (-1, 5) and a point on the circle is (4, 4).

Step-by-step explanation:

Use the distance formula to find the radius using the center (-1,5) and the point (4,4).

This implies that;

We use the formula:

The required equation is

answer: ouch. thats difficult

step-by-step explanation:

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%
