How to express cartesian coords as polar coords.

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.

i believe the answer is y=0.25x+-3

(f+g)(x) = 3^x+10x+4x-2

      =3^x +14x-2
