Write a short statement that expresses a possible function between the given variables.(price of a DVD player, demand for DVD pl
Gala2k [10]

Answer:

When the price of DVD player increases, the demand will decrease.

Step-by-step explanation:

The price and demand function have an inverse relationship. When the price of good increases its demand will decrease. This is law of demand. If the price of goods increase to a certain level its demand will start decreasing. The people will start buying lesser good and will consume less. The propensity to consume will decline and less economic goods will be consumed. When the price of DVD player is increased then the demand will decline for DVD players and people will drop the decision to buy the DVD player.

Write an expression for the volume of a rectangular prism with length 7.5 ft, width w ft, and height 4.2 ft. Enter the smaller n
Reil [10]

Answer:

volume = 31.5w  

Step-by-step explanation:

A rectangular prism is a 3 dimensional figure that have 6 faces that are rectangular in shape. To ascertain the volume of a rectangular prism you need to know the length, width and height. The formula for the volume of a rectangular prism is represented below .

volume of a rectangular prism = LHW

where

L= length

H = height

W = width

volume = LHW

L = 7.5 ft

W = w ft

H = 4.2 ft

The expression for the volume of a rectangular prism with the following value above can be represented below.

volume = 4.2 × 7.5 × w

volume = 31.5w

ASAP! Please do 1-5 and show work if possible!
Blababa [14]

Answer :

(1) The radius of a circle is 1.5 m.

(2) The diameter of a circle is 28 ft.

(3) The radius of a circle is 10 in.

(4) The circumference of circle is 47.14 m.

(5) The circumference of circle is 44 yd.

Step-by-step explanation :

Part 1:

Given: d = 3 m

Now we have to determine the radius of circle.

As we know that:

Radius of a circle = \frac{Diameter}{2}

So,

Radius of a circle = \frac{3m}{2}=1.5m

The radius of a circle is 1.5 m.

Part 2:

Given: r = 14 ft

Now we have to determine the diameter of circle.

As we know that:

Radius of a circle = \frac{Diameter}{2}

So,

Diameter of a circle = Radius\times 2

Diameter of a circle = 14ft\times 2=28ft

The diameter of a circle is 28 ft.

Part 3:

Given: d = 20 in

Now we have to determine the radius of circle.

As we know that:

Radius of a circle = \frac{Diameter}{2}

So,

Radius of a circle = \frac{20in}{2}=10in

The radius of a circle is 10 in.

Part 4:

Given: d = 15 m

Now we have to determine the circumference of circle.

Formula used:

C=\pi d

where,

C = circumference

d = diameter

So,

C=\frac{22}{7}\times 15m

C=47.14m

The circumference of circle is 47.14 m.

Part 5:

Given: r = 7 yd

Now we have to determine the circumference of circle.

Formula used:

C=\pi d

or we can write,

C=\pi (2\times r)

where,

C = circumference

d = diameter

r = radius

So,

C=\frac{22}{7}\times (2\times 7yd)

C=44yd

The circumference of circle is 44 yd.
