1. An apple falls from a 28 foot tree. The height of the apple, in feet, after t seconds of falling, can be found using the polynomial -16t2 + 28. Find the apple's height after 0.5 second.
2. Find the measure of each of the interior angles and exterior angles of a regular hexagon.
3. There are 30 students auditioning for new openings in a chorus. How many ways can you choose 4 students to be in the chorus?
4. You and four friends are going to a movie. In how many different orders can you pick your friends up?
5. You draw a marble at random from a bag of red, blue, green, and yellow marbles 24 times. Each time you record its color and place it back in the bag of 75 marbles. The results are shown in the table below. How many of each color marble do you predict are in the bag?
Red = 7, Blue = 3, Green = 5, Yellow = 9
What is the diameter of a cone with a height of 10 yards and a volume of 92.4 cubic yards? Round to the nearest whole number.
Thank you

1. y = -16(0.25)+28 = 24 ft. ( This is the height of the apple after 0.5 sec).
2. Total = 540 deg. So each interior angle is: 90deg. Ext angle: 90 deg.
3. (30 c 4)= 27405
4. 5 p 4 = 120
