Write a few sentences explaining how to determine whether a relation shown in a table or a graph is a function.

ohaa [14]

Answer:

y=f(x)

y=5x

y=3x

are examples of function

Step-by-step explanation:

definition of a function

if there is one to one relation between a relation

then it is defined as a function

for example

y=5x is a function

because when we put some value of x it gives back only one value of y as output.

y=±5x is not a function because one value of x gives two values(positive and negative) values of y hence not a function.

A building in the shape of a square pyramid is being built in Las Vegas. The height of the building will be 309 feet, and a size

finlep [7]

Answer: 51.5 cubic feet.

Step-by-step explanation:

Since, The height of the building will be 309 feet, and a size of the base measures 250 feet.

And, we know that the volume of the square pyramid = $(size of the base)^2\times \frac{height}{3}$

Here, size of the base of the square pyramid = 250 feet.

And, height = 309 feet.

Therefore, the volume of the given square pyramid,

$V=(250)^2\times\frac{309}{3}$

⇒ $V=62500 \times\frac{309}{3}$

⇒ $V= \frac{19312500}{3}$ = 6437500 cubic feet.

Again according to the question,

The scale model that is displayed at a convention is one fiftieth the size of the actual building.

Therefore, Volume of the scale model = the volume of the given square pyramid/125000

= 6437500/125000= 51.5 cubic feet.

Thus, the volume of the scale model is 51.5 cubic feet.

ASAP!! Find the length of side x in simplest form with a rational denominator

lidiya [134]

Answer:

$x=\sqrt{14}$

Step-by-step explanation:

This triangle is a 45-45-90 triangle.

By using the image I posted, we can find x easily.

So, we have $\sqrt{7}$ as one of the sides.

They hypotenuse, which is x is just $\sqrt{7} \sqrt{2}$

Simplify and we get x = $\sqrt{14}$
