The height ,h, in feet of a baseball that is popped up into the air is a quadratic function of the time, t, in seconds, since it was hit. an equation that may model this situation is h(t)=4+60t-16t^2. answers the following questions accurately, rounding to two decimals places when needed.

Step-by-step explanation:

The exercise provides you the following Quadratic function:

You know that it represents the height (in feet) of the ball as a function of the time (in seconds) since the ball hit the bat.

Based on this, you can conclude that when the ball strikes the bat the time in seconds is:

Therefore, in order to calculate the height in feet of the ball when it strikes the bat, you need to subsititute into the function and    then evaluate.

So, you get:

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
