A football coach uses a passing machine to simulate 50-yard passes during practice. the quadratic function f(x)=-16x+60x+5 models the height of the football after x seconds. how long is the football in the air if not caught?

If not caught, the football is in the air for about 3.83 seconds

The quadratic function:

models the height of a football after x seconds, so we want to know how long the ball is in the air if not caught. The ball lands on the ground when . Then, our equation becomes:

Using quadratic formula we can get the x-values that makes this equation to be true:

Since time can't be negative we discards so the only valid solution is .

In conclusion: If not caught, the football is in the air for about 3.83 seconds

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.

step-by-step explanation:

answer: x=1

step-by-step explanation:

f(x) = g(x)

x - 2 = -1

x = 1

therefore the graph should be a line showing x=1 which is vertical and passes on 1

hope it !
