slavikrds [6]

Answer:

It will travel high enough

Step-by-step explanation:

Find the vertex of the parabola:

x=-b/2a

x=-11/2(-16)

x=-11/-32

x=11/32

Plug x=11/32 into quadratic to get the y-coordinate:

h=-16(11/32)^2+11(11/32)+5.5

h=7.391

Since 7.391>7.3, the volleyball will travel high enough (aka. yes)

Answer:

The missing value of x is 3

Step-by-step explanation:

Given Table:

  x     y

 3      10

__    20

The relation of x and y (x,y) is not a function.

Relation is function if it is one-to-one.

One-to-one means to different value of x to get different value of y.

If function is not a function then one value of x to get two different value of y.

For first value of x=3, y=10

For which value of x= ? , y=20

x must be 3

x=3 to get y=20

The missing value of x is 3 because same of x we get two different value of y.
