Answer:

This is direct variation.

Step-by-step explanation:

The direct variation is a relationship between two variables that are related by a proportionality constant.

It can be written as y=kx ; where k is proportionality constant .

In inverse variation the product of two variables is equal to a constant.

Given statement here is :

The number of tons of coal burned by an old coal burning locomotive under given conditions varies as the number of hours.

This is direct variation as the more the train runs, the more coal is used.

Let number of tons of coal be = t

Let the number of hours be = h

So, we can relate this as : t=k\times h

't' can be calculated if you know the constant k.

The answer for the question shown above is the first option, which is:
 - Direct.

 The explanation is shown below:
 1. The problem says that <span>The number of tons of coal  varies as the number of hours.
 2. Therefore, you can write the following equation:
 number of tons:x
 number of hours:y
 x=ky
 Where k is the constant of variation.
 3. Therere the variation is direct.</span>

P(x)=2x^3-11x^2+ax-40 if x+4 is a factor of this polynomial what is the value of a
Vika [28.1K]

Answer:

a = -86.

Step-by-step explanation:

By the Factor Theorem, if x + 4 is a factor then P(-4) = 0, so:

P(-4) = 2(-4)^3 - 11(-4)^2 + a(-4)- 40 = 0

-128 - 176 - 4a - 40 = 0

-4a = 128 +176 + 40

-4a = 344

a = -86.

Samantha has a rectangular shaped fish tank in her room. The tank has a height of 2.6 ft, a width of 2.1 ft, and a length of 3.9
andrezito [222]

Answer: the BEST approximation of the amount of water her fish tank can hold is 21ft^3

Step-by-step explanation:

The shape of Samantha's fish tank is rectangular. The volume of the rectangular fish tank would be expressed as LWH

Where

L represents length of the tank

W represents the width of the tank.

H represents the height of the tank.

The tank has a height of 2.6 ft, a width of 2.1 ft, and a length of 3.9 ft.

This means that the volume of the fish tank would be

Volume = 2.6 × 2.1 × 3.9

= 21.294 ft^3
