The height of the baseball after the 1.5 seconds of time as the boy throw the ball is 15.5 meters.
The mathematical functions is used to represent the general problem in the mathematical way to solve them.
Steps to write down the simple mathematical function-
A boy throws a baseball across a field. The ball reaches its maximum height, 18 meters, after 1 second.
After approximately 2.3 seconds, the ball lands on the ground.
The ball’s motion can be modeled using the function
[tex]f(x) = -10x^2 +20x+ 8[/tex]
Here, x represents the time in seconds.
As, the height of the ball 1.5 seconds after it is thrown has to be found out. Thus, put the values of in the above equation as,
[tex]f(x) = -10(1.5)^2 +20(1.5)+ 8\\f(x)=-22.5+30+8\\f(x)=15.5\rm \; m[/tex]
Hence, the height of the baseball after the 1.5 seconds of time as the boy throw the ball is 15.5 meters.
