3) the height of an object that is thrown straight up from a height of 6 feet

above ground is given by h(t) = -15t2 + 25t + 6, where t is the time in

seconds after the object is thrown. find the average rate of the object from

1 to 4 seconds.

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.

happy to
