Find an equation of the circle that satisfies the given conditions. (Use the variables x and y.) Center at the origin;
passes through (4, 6)

Step-by-step explanation:

Distance between two points:

Suppose that we have two points, and . The distance between them is given by:

Equation of a circle:

The equation of a circle with center and radius r has the following format:

Center at the origin;

This means that

So

Passes through (4, 6)

The radius is the distance from this point to the center. So

So

Then

answer: the answer is 5/22

step-by-step explanation: if you subtract 17 from 22 the answer is 5 therefore the remainder of students are female

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
