Henry predicts the amount of wheat, in bushels, produced on his farm t years from now can be modeled by the function W(t)=70t+900. The price, in dollers, per bushel of wheat t years from now can be modlesd by the function P(t)=0.25t+6. Write a function of I to describe the total income henry predicts for producing wheat t years from now

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.

Iwould say 48 bc the line of x is the line of 6 so 6×6=48
