Circle P is tangent to the x-axis and the y-axis. If the coordinates of the center are (r. 1), find the coordinates of the points of tangency.
(0.1) and (0)
O(r. r) and (0,0)
O (0.12) and (1/2r, 0)

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.

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
