Answer:

(x+1)^2+(y-1)^2=49

Step-by-step explanation:

The standard equation of a circle is

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

where the center is (h,k) and r is the radius

so h=-1 and k=1 in this case

so then (x- -1)^2+(y-1)^2=7^2

(x+1)^2+(y-1)^2=49

Answer:

(x+1)^2 + (y+1)^2 = 49

Step-by-step explanation:

We can write the equation of a circle as

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

where (h,k) is the center and r is the radius

(x- -1)^2 + (y- -1)^2 = 7^2

Simplifying

(x+1)^2 + (y+1)^2 = 49

What needs to be corrected in this construction of a line parallel to line AB passing through C?
UNO [17]

The option that needs to be corrected in this construction of a line parallel to line AB passing through C is C: the second arc should be centered at C.

<h3>Why should the second arc be centered at C?</h3>

The second arc should be centered at C because as it crosses passing through Line C, it is seen that it was not touching or intersecting AB and so one can say that it is parallel to it.

Looking at the other lines, we will see that they are all touching AB and are not running parallel to it.

Hence, The option that needs to be corrected in this construction of a line parallel to line AB passing through C is C: the second arc should be centered at C.
