Is this relation a function? EXPLAIN WHY OR WHY NOT
olga_2 [115]

This relation is a function, because you are assigning one y-value to each x-value. In other words, you can perform the vertical line test: you can see that every vertical line crosses the graph at most once.

Answer:

\large\boxed{\begin{array}{c|c|c|c}Length:&4cm&2cm&8cm\\Width:&6cm&12cm&3cm\\Height:&9cm&9cm&9cm\end{array}}

Step-by-step explanation:

The formula of a volume of a cube with side length a:

V=a^3

We have a = 6cm. Substitute:

V=6^3=216\ cm^3

\begin{array}{c|c}216&2\\108&2\\54&2\\27&3\\9&3\\3&3\\1\end{array}

216=2\cdot2\cdot2\cdot3\cdot3\cdot3=(2\cdot2)\cdot(2\cdot3)\cdot(3\cdot3)=4\cdot6\cdot9\\\\216=2\cdot2\cdot2\cdot3\cdot3\cdot3=2\cdot(2\cdot2\cdot3)\cdot(3\cdot3)=2\cdot12\cdot9\\\\216=2\cdot2\cdot2\cdot3\cdot3\cdot3=(2\cdot2\cdot2)\cdot3\cdot(3\cdot3)=8\cdot3\cdot9\\\vdots

One side of a triangle is 2 times the second side. The third side is 5 ft longer than the second side. The perimeter of a triang
TiliK225 [7]

Answer:

The length of each side of triangle are 19 ft, 24 ft and 38 ft.

Step-by-step explanation:

Let the length of second side be x.

Now given:

Length of first side is 2 times length of second side.

Length of first side = 2x

Also, Length of third side is 5 ft longer than the second side.

Length of third side = 5+x

Perimeter of triangle = 81 ft.

We need to find the length of each side.

Now perimeter of triangle is sum of all three sides of triangle.

Therefore;

Perimeter of triangle =  Length of first side + length of second side + Length of third side.

2x+x+5+x=81 ft\\4x+5=81ft\\4x= 81 -5 ft\\4x = 76ft\\x= \frac{76}{4} = 19 ft

Length of Second Side = 19 ft.

Length of First side = 2x= 2\times19 = 38 ft

Length of Third side = 5+x= 5+19=24ft

Hence the Length of triangles are 19 ft,38 ft,24 ft.
