A 6 foot tall man walked due west, in the exact direction of the setting sun, at a rate of 1.5ft/sec. At the moment just before he sees the sun disappear behind a building that is 150 feet high, at what rate is the length of his shadow changing?

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!
