A baseball diamond is a square with side 90 feet. A batter hits the ball and runs toward first base with a speed of 21 ft/s. (a) At what rate (in ft/s) is his distance from second base decreasing when he is halfway to first base? (Round your answer to one decimal place.)
(b) At what rate (in ft/s) is his distance from third base increasing at the same moment? (Round your answer to one decimal place.)

b. x + 1

step-by-step explanation:

i'am smart

what

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!

i would say true? if the unit was informational and it "refreshed your understanding", then true.
