Find an equation of the sphere with center (1, −7, 3) and radius 5. (x−1)2+(y+7)2+(z−3)2=25 Use an equation to describe its intersection with each of the coordinate planes
(If the sphere does not intersect with the plane, enter DNE.)
intersection with xy-plane:
intersection with xz-plane:
intersection with yz-plane:

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

your answer is -9

step-by-step explanation:

5/20 so 25%
