The flight of a helium balloon can be approximated by the function, f (x) = -0.5x^2 + 20x + 30 where f(x) represents the height of the balloon in yards and x is the time in seconds. What is the maximum height of the balloon?

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!
