Mathematics
1 answer:
Shtirlitz [24]3 years ago
6 0

Answer:

( x +2)² + ( y - 4)² = 81

Step-by-step explanation:

The equation for a circle in standard form is ( x – h)² + ( y - k)² = r², where the center is (h, k) and the radius is r.

Putting the question's given information into the formula gives you

[ x – (-2)]² + ( y - 4)² = (9)²

( x + 2)² + ( y - 4)² = 81

A phone cost 199$ and is on sale for 25% off. What is the sale price?
andrey2020 [161]

Answer:

<em>See below.</em>

Step-by-step explanation:

Divide the percentage by 100 to turn it into decimal form.

\frac{25}{100}=.25

Then, multiply the percentage by the original amount.

199*.25=49.75

Last, subtract that from the original price.

199-49.75=149.25

<em>Answer: </em>149.25

By what factor would your weight be multiplied if earth's diameter were 1/ 4 as big and earth's mass remained unchanged?.
GenaCL600 [577]

Answer:

  16

Step-by-step explanation:

Your weight is (roughly) proportional to the inverse of the square of the distance you are from the center of the earth. If that distance is reduced to 1/4 its previous value, then your weight will be multiplied by the factor ...

  1/(1/4)² = 16

You would weigh 16 times as much.

_____

<em>Additional comment</em>

The distribution of mass within the earth also affects your weight.

Use the given equation to find the number<br><br> 1/2x-19.7=-4.1
Leokris [45]

Answer:

the number is 31.2

Step-by-step explanation:

Given that:

1/2x-19.7=-4.1

Adding 19.7 on both sides:

1/2x-19.7 + 19.7=-4.1 + 19.7

1/2x = 15.6

Multiplying both sides by 2:

x = 15.6 * 2

x = 31.2

So the number is 31.2

i hope it will help you!
