Keith applies a new brand of fertilizer to his grass.
He finds that the rate at which the grass grows can be modeled by a linear function.
He observes that the rate of growth is 1 centimeter every 3 days.
After 18 days, he measures the height of the grass to be 8 centimeters.
The initial height of the grass was c entimeters tall.

hey! so 1 (25) out of 4 (100) is 25 so your answer is 25%. it's like quarters!

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c
