What are the coordinates of the center of a circle whose equation is (x + 7)2 + (y – 5)2 = 16?

Dafna11 [192]

Hi there! The answer is ( - 7, 5)

The standard form of the equation of a circle is the following:
$(x - a) {}^{2} + (y - b) {}^{2} = r {}^{2}$

In this equation r represents the radius of the circle and the point (a, b) is its centre.

Therefore, the centre of the circle
$(x + 7) {}^{2} + (y - 5) {}^{2} = 16$
is the point ( - 7, 5).

It took Trina 1 hour and 30 minutes to shovel the snow from her neighbor’s driveway. During that time she burned 630 calories. H

Kazeer [188]

Answer:

Step-by-step explanation:

The first step to solve this problem is to convert 1h 30min into just minutes. since there are 60 minutes in 1 hour you take 60 and add it ot the 30 extra minutes to get a total of 90.

Now, this question is asking you to find how many calories <u>per</u> minute she burns. When you are asked to find ___ per___ all you have to do is divide the first number by the second one. In this case you will divide calories by minutes.

630/90=<u>7</u>
