Write the standard equation for the circle center left parenthesis negative 6 comma 7 right parenthesis, r = 9.A. left parenthesis x minus 6 right parenthesis squared plus left parenthesis y plus 7 right parenthesis squared equals 9
B. left parenthesis x minus 7 right parenthesis squared plus left parenthesis y plus 6 right parenthesis squared equals 81
C. left parenthesis x plus 6 right parenthesis squared plus left parenthesis y minus 7 right parenthesis squared equals 81
D. left parenthesis x plus 6 right parenthesis squared plus left parenthesis y minus 7 right parenthesis squared equals 9

Answers

Answer:

Step-by-step explanation:

The standard form equation for a circle is

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

where h and k are the coordinates of the center. Our center is given as (-6,7)  and the radius is given as 9, so that information fits into our standard form like this:

(x-(-6))^2+(y-7)^2=9^2 and simplified, it looks like this:

(x+6)^2+(y-7)^2=81

That's choice C

A wheel has a diameter of x inches and a second wheel has a diameter of y inches. The first wheel covers a distance of d feet in 100 revolutions. How many revolutions does the second wheel make in covering d feet?

Answers

You'd want an expression which relates to x, y and d.
The distance d is x times pi times 100. One divides back by pi and by y to get the # of revolutions (that 100 :)) ) and so one gets (100x)/(y) as the number of revolutions.

A bag contains 6 green marbles, 9 red marbles, 7 white marbles, and 3 black marbles. What is the probability of drawing a red marble out of the bag? A. 1/18


B. 9/16


C. 9/25


D. 1/4

Answers

The answer is C. 9/25.

There are in total 25 marbles:
6 green + 9 red + 7 white + 3 black = 25 marbles.

There are 9 red marbles of the total 25 marbles. You can draw 9 red Thus, the probability of drawing a red marble out of the bag is 9 out of 25, which is 9/25.

What is 1,395 rounded to the nearest interer? 99

Answers

If you meant integer, then the correct answer is 1,395. An integer is a whole number, which means that the first integer place is the ones place. Since the number is 1,395, it is a whole number, so the digit in the tenths place, to the right of the ones place, is 0. Since 0 is less than one, we keep the ones place the same, so 1,395 remains 1,395.

Hope this helps!
