Answer:

2) II and IV

Step-by-step explanation:

A function will have only one output value for any given input.

I. The table has two different outputs for an input of x=2.

II. The first values of the ordered pairs are all unique. This is a function.

III. The graph shows two different output values for each x input that is greater than 0.

IV. A polynomial always represents a function.

The representations in II and IV are functions.

Find the missing dimension of each prism.

Leto [7]

Given:

Volume of the prism = 60 in³

Breadth = 2.5 in

Height = 4 in.

To find:

The length of the prism.

Solution:

We know that, volume of a prism is

$V=l\times b\times h$

where, l is length, b is breadth and h is height.

Putting V=60, b=2.5 and h=4, we get

$60=l\times 2.5\times 4$

$60=l\times 10$

Divide both sides by 10.

$\dfrac{60}{10}=l$

$6=l$

Therefore, the missing dimension of the prism is 6 in.
