What is the correct equation of the circle with the center (4, 6) and radius 6?
A) (x +4)2 + (y + 6)2 = 36
B) (x-4)2 + (y – 6)2 = 36
C) (x-4)2 + (y – 6)2 =6
D) (x+4)2 + (y + 6)2 = 6

Which of the following lines is parallel to x=4? a- 3y=9 b- y=4 c- x=2 d- x=y answer this as soon as possible xoxo lo ; )

Me. i can't figure out this question. give an explanation too. .

Sketch the region enclosed by the given curves. decide whether to integrate with respect to x or y. draw a typical approximating rectangle and label its height and width. y= 5x, y=7x^2then find the area s of the region.
