A football player kicks a ball with an initial velocity of 47 feet per second. The initial height of the ball is 4 feet. The function h(t)=−16t2+47t+4 models the height (in feet) of the ball, when t is the time in seconds. What is the maximum height the ball reaches? Round to the nearest ½ foot. If no one catches the ball, how long will it be in the air? Round to the nearest second

hi,

6x times 4 is 24x and 5 times 4 is 20, so the answer is 24x+20.

hope this and for a little humor i am groot.

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 : )
