Write the equation of the circle with the given graph.

Mathematics
1 answer:
lara [203]2 years ago
7 0

By identifying the radius and the center, we concluded that the equation is something like:

(x - 2)^2 + (y - 1.5)^2 = 1.8^2

<h3></h3><h3>How to write the equation of the circle?</h3>

For a circle centered on the point (a, b) with a radius R, the equation is:

(x - a)^2 + (y - b)^2 = R^2

So first we need to identify the center, we can see that it is: (2, 1.5)

And the radius is the distance between the center and the edge.

R  = 1.8 (measured with a ruler, respecting the notation of the graph).

Then the equation of the circle is something like:

(x - 2)^2 + (y - 1.5)^2 = 1.8^2

<h3>There are 29 total number of questions on his math test</h3>

<em><u>Solution:</u></em>

Given that,

Amanda answered all the questions on her math test but got 10 answers wrong

She received 4 points for every correct answer, and there were no points for wrong answers

<em><u>Find the number of questions answered correctly:</u></em>

Her final score was 76 points

4 points for every correct answer

Thus,

correct\ answers = \frac{76}{4} = 19

From given.

Incorrect answers = 10

Let "x" be the total number of questions on his math test

Then,

x = correct answered questions + incorrect answered questions

x = 19 + 10

x = 29

Thus there are 29 total number of questions on his math test

So I have a question. Its a really good question. I'm not sure you'll get it though. Okay so my question is if a train leaves a
Marta_Voda [28]

Answer:

  • 12:42 (approximately)

Step-by-step explanation:

Train 1 will travel for 2 hours before the second train leaves.

<u>The distance at 2 o'clock is reduced by 2*90 = 180 miles and now is:</u>

  • 2000 - 180 = 1820 miles

<u>Let the trains spend x hours before crossing, then we have following equation for the distance:</u>

  • x(90 + 80) = 1820
  • 170x = 1820
  • x = 1820/170
  • x = 10 120/170 = 10 12/17 hours ≈ 10 hours and 42 minutes

<u>The trains will cross at:</u>

  • 2 o'clock + 10 h 42 min = 12:42

The time when trains cross each other will be approximately 12:42
