You have the maximum height happens at 5 seconds.
Replace t with 5 and solve for h(t):
h(5) = -0.2(5)^2 + 2(5)
h(5) = -0.2(25) + 10
h(5) = -5+10
h(5) = 5
The maximum height is 5 feet.

Answer:
- 63 in the class
- (C+B)P' = 25
- (C+B+P)' = 18
Step-by-step explanation:
The number of students in the class is the total of all numbers on the diagram:
9 +5 +11 +6 +3 +4 +7 +18 = 63 . . . students in the 2015 senior class
__
Students taking Chem or Biology, but not Physics are those in the colored area, excluding those in the green:
9 +5 +11 = 25 science students not taking Physics
__
Students not taking science are those outside the colored areas:
18 students are not taking science
Answer:
The value of x is 21 .
Step-by-step explanation:
We are given that x varies directly as y
--- A
We are given that x = 7 and y = 28
Substitute the values in A
7 = 28k
Now equations becomes :
y = 84
Hence The value of x is 21 .

Answer:
Missing frequency = 4
Step-by-step explanation:
Given:
Qty Number
1 5
2 6
3 5
4 6
5 □
6 5
7 8
8 4
9 4
10 3
Total 50
Find:
Missing frequency
Computation:
Missing frequency = Total frequency - Counted
Missing frequency = 50 - 46
Missing frequency = 4
