Max height is the vertex
convert to vertex form (y=a(x-h)^2+k) by completeing the square
h(t)=-16(t²-4t)+80
h(t)=-16(t²-4t+4-4)+80
h(t)=-16((t-2)²-4)+80
h(t)=-16(t-2)²+64+80
h(t)=-16(t-2)²+144
vertex is (2,144)
at t=2, the height is 144
max height is 144ft

That is 1075 / 56 = 19.2
Answer: 19
It is number C.
It is -11,2,7,8,22
Answer:
The correct option is B.
Step-by-step explanation:
In a program the variables are defined as
int a, b =2;
float c = 4.2;
The given statement is
a = b * c
a = 2 * 4.2
a = 8.4
It is given that variable a is an integer. So, only integer value can be stored in a.
a ≈ 8
It means 8 will be stored in a. Therefore the correct option is B.
To determine which seating arrangement would be able to seat more people you will find the distance around each table.
For the rectangle, you will find the perimeter:
P = 2l + 2w
2 x 6 + 2 x 4
P = 20 feet
For the circle you will find the circumference:
C = pi x d
3.14 x 6
C = 18.84 feet
The rectangle would seat more people because the distance around the table is longer.
You would be able to fit about 7-8 people around the rectangular table and 6-7 people around the circular table.
