Question

a missile is launched from the ground. its height, h(x), can be represented by a quadratic function in terms of time, x, in seconds.
after 1 second, the missile is 58 feet in the air; after 2 seconds, it is 112 feet in the air.
the height of the can be represented by this function:
h(x) = -2x² + 60x
find the height, in feet, of the missile after 10 seconds in the air.
enter the correct answer.

Explanation:

Step1: Substitute x=10 into function

$h(10) = -2(10)^2 + 60(10)$

Step2: Calculate squared term

$h(10) = -2(100) + 60(10)$

Step3: Compute multiplications

$h(10) = -200 + 600$

Step4: Final addition

$h(10) = 400$

Answer:

400
