Day: Monday, Tuesday, Wednesday, Thursday, Friday
frequency: 3, 1, 1, 1, 5
Frequency is the repeated number of times so you just need to count how many times a day repeats.
There is an area of 180 square ft. Hope this helps (:
If there are 9 students then they each get 20 and if there are 6 they each get 30. If that answers the question.
A. Convert to vertex form:-
= -0.8(x^2 - 4x) + 6
= -0.8 ((x - 2)^2 - 4)) + 6
= -0.8(x - 2)^2 + 9.2
Maximum height of the ball is 9.2 feet Answer
b. horizontal distance at this height = 2 feet. Answer
c. this distance will be the positive root of f(x) = 0
-0.8(x - 2)^2 = -9.2
(x - 2)^2 = 11.5
xi-2 = sqrt 11.5 = 3.39
required distance = 5.39 = 5.5 feet answer
