Which is the correct calculation of the y-coordinate of point A? 0 (0 - 0)2 + (1 - y2 = 2 O (0 - 1)² + (0- y2 = 22 (0-0)² + (1 -
dimaraw [331]

Answer:

The y-coordinate of point A is \sqrt{3}.  

Step-by-step explanation:

The equation of the circle is represented by the following expression:

(x-h)^{2}+(y-k)^{2} = r^{2} (1)

Where:

x - Independent variable.

y - Dependent variable.

h, k - Coordinates of the center of the circle.

r - Radius of the circle.

If we know that h = 0, k = 0 and r = 2, then the equation of the circle is:

x^{2} + y^{2} = 4 (1b)

Then, we clear y within (1b):

y^{2} = 4 - x^{2}

y = \pm \sqrt{4-x^{2}} (2)

If we know that x = 1, then the y-coordinate of point A is:

y = \sqrt{4-1^{2}}

y = \sqrt{3}

The y-coordinate of point A is \sqrt{3}.

The drawing is a scale drawing of a house.
Alborosie

Answer: 20.25ft

1. Find what 8 inches in scale equal for the height of the house.

we will do this step by multiplying.

2in=4.5

8=?

to find...

2x4=8

so

4.5x4=18

2. Find what 1 inch on the scale is equal to for the height of the house.

we will do this by dividing 4.5 by 2

4.5/2=2.25

3. Add both the values for step 1 and 2.

we will do this by just adding them both

18+2.25=20.25

<h2>Why is this our answer?</h2>

This is our answer, because first we found the value of 8 inches on the scale, which means that we are finding almost the full value of the 9 inches of the height of the house, then, we found 1 inch because 9-8=1, so if we already found 8, which is a number in the table of 2, we found out 1 so that we can add it with 8 to find the value of 9in on the scale. In this way, after adding, that gives us the value of 9in on the scale!

My gratitude attitude - THANKS!

Fran cycles at a speed of 5.3 m/s for 5 minutes.<br><br> How far does she travel?
chubhunter [2.5K]

Step-by-step explanation:

In 1 second Fran cycles 5.3 m.

So we need to work out how many seconds is in 5 minutes.

1 minute = 60 seconds

5 minutes = 60*5 = 300 seconds

So Fran cycles at a speed of 5.3 m/s in 300 seconds.

1 second = 5.3m

300 seconds = 5.3*300 = 1590m

Hope this helps!

What is the solution set for 3x&gt;6?
zalisa [80]
Isolate the x

divide 3 from both sides

3x/3 > 6/3

x > 6/3

x > 2 is your answer

Note: because you are not dividing by a negative number, you do not need to flip the sign

hope this helps
