Identify the equation of the circle that has its center at (16, 30) and passes through the origin

Mathematics

Veronika [31]3 years ago

To solve this question, we have to find the equation of the circle with given center and where it passes. Doing this, we get that the equation of the circle is:

(x - 16)^2 + (y - 30)^2 = 1156

Equation of a circle:

The equation of a circle with center (x_0, y_0) and radius r is given by:

(x - x_0)^2 + (y - y_0)^2 = r^2

Center at (16, 30)

This means that x_0 = 16, y_0 = 30

Thus

(x - 16)^2 + (y - 30)^2 = r^2

Passes through the origin:

We use this to find the radius squared, as this means that x = 0, y = 0 is part of the circle. Thus

(x - 16)^2 + (y - 30)^2 = r^2

(0 - 16)^2 + (0 - 30)^2 = r^2

r^2 = 16^2 + 30^2 = 1156

Thus, the equation of the circle is:

(x - 16)^2 + (y - 30)^2 = 1156

For another example to find the equation of a circle, you can look at brainly.com/question/23719612

How do I find the slope of this altitude?<br><br>I am referring to question 19.
Crazy boy [7]
The altitude's slope must be perpendicular to that of the line. 

The slope of segment BC is 2/5. The slope of the altitude must be perpendicular to 2/5. Since the negative reciprocal of 2/5 is -5/2, then the slope of the altitude is -5/2.

May runs around a 4 m track at a consistent speed of 250 m/min. how many minutes does it take me to complete for lapse of the tr
Nookie1986 [14]

Answer:

<u>It takes May 6 minutes and 24 seconds to run 4 laps and 1 minute and 36 seconds per lap</u>

Statement and question:

May runs around a 400-meter track at a constant speed of 250 meters per minute. How many minutes does it take May to complete 4 laps of the track?

Source:

Previous question that can be found at brainly

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Speed of May = 250 meters per minute

Length of the track = 400 meters

2. How many minutes does it take May to complete 4 laps of the track?

Let's answer the question calculating the total distance and the time it took Mary to run around the track, this way:

Total distance = 4 * 400 = 1,600 meters

Time it takes May to run 1,600 meters = 1,600/250

Time it takes May to run 1,600 meters = 6.4 minutes

<u>6.4 minutes = 6 minutes + 0.4 * 60 seconds = 6 minutes and 24 seconds</u>

<u>Time it takes May to run one lap = 6.4/4 = 1.6</u>

<u>1.6 minutes = 1 minute + 0.6 * 60 seconds = 1 minute and 36 seconds</u>

A book club has 36 members. There are 24 boys and 12 girls in the club. What is the ratio of the number of boys in the club to t
Ivanshal [37]

Step-by-step explanation:

Ratios can be written as:

a to b

a:b

a/b

We want to find boys to girls, and there are 24 boys and 12 girls. So, we can write it as

24 to 12

24:12

24:2

All of these can be reduced, since both the numerator and denominator can be divided by 12.

Numerator: 24/12=2

Denominator: 12/12=1

2 to 1

2:1

2/1
