1. Suppose Brett and Samantha each throw a baseball into the air. The height of Brett's baseball can be represented by the following equivalent equations, where h(t) is height in feet and tis time in seconds: h(t) = -16(t+ 0.1)(t-5) h(t) = - 16t2 + 78.4t+8 h(t) = -16(t-2.45)2 + 104.04 The height of Samantha's baseball is given by the graph below: |(2,64) 65 GO height (in feet) 55 45 25 10 time (in seconds) a. The two kids were interested in comparing their throws. Begin by analyzing the flight of Brett's baseball. What is the baseball's height after 3 seconds? Does it matter which of the three equations you use?

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 : )

the answer is a) y= 2 csc [0.5 (x+pi/2)]-1

step-by-step explanation:

all you should have to do is insert 1 where the c is, representing that one car is sold.

f(c) = 250c + 500

f(1) = 250(1) + 500

f(1) = 250 + 500

f(1) = 750

he earns $750 for each car sold.

hope this you! have a happy , here's a turkey!
