Answer:

Part A - Represents a function

Part B - Doesn't represent a function.

Step-by-step explanation:

A set is just a list of numbers to check. The question is asking you based on the set...

(-5, 8)

(-6, 2)

(-2, -6)

(-1, 8)

(4,6)

if it is a valid function.

At NO point should a function have multiple x values. This fails the <em>Vertical Line Test</em> if visualized on a graph.

For Part A, there are no duplicate x values, meaning this function is valid.

For Part B, there is a duplicate x value - (2,9) & (2,4). Because of this, immediately the function is invalid. There can not be any duplicate x values in a valid function, <u>PERIOD</u>. If graphed, it fails the vertical line test.

Answer:

2). Volume = 14400 feet³

3). Volume = 157.5 ft³

Step-by-step explanation:

Both the figures given in the sheet attached are a rectangular pyramid and a triangular prism.

2). In this part of the question solid given is in the shape of an rectangular pyramid.

Volume of this oblique pyramid = $\frac{1}{3}(\text{Base})(\text{Height})$

Here 'B' = area of the base

h = height of the pyramid

Volume = $\frac{1}{3}(25\times 36)\times 48$

= 14400 cubic feet

4). Volume of a triangular cone = (Area of the triangular base)×(height)

= $[\frac{1}{2}(\text{Base})(\text{height})]\times {\text{height of the prism}}$

= $\frac{1}{2}(7\times 9)\times {5}$

= 157.5 ft³

Scrat [10]

Answer:

35 grams of 11.43% solution

Step-by-step explanation:

The end solution has same volume as initial volumes of mixture.

10 + 25 = 35 g

The concentration of solution is calculated as below

10*0.15 + 25*0.1 = 4 g
4 / 35*100% = 11.43% (rounded)
