Find the value of x that maximized the volume of the following:

Mathematics

Shtirlitz [24]2 years ago
5 0

Check the picture below.

as you can see, the graph of the volume function comes from below goes up up up, reaches a U-turn then goes down down, U-turns again then back up to infinity.

the maximum is reached at the close up you see in the picture on the right-side.

Why we don't use a higher value from the graph since it's going to infinity?

well, "x" is constrained by the lengths of the box, specifically by the length of the smaller side, namely 5 - 2x, so whatever "x" is, it can't never zero out the smaller side, and that'd happen when x = 2.5, how so? well 5 - 2(2.5) = 0, so "x" whatever value is may be, must be less than 2.5, but more than 0, and within those constraints the maximum you see in the picture is obtained.

An expression is defined as a set of numbers, variables, and mathematical operations. The value of x for which the expression (x-1)(x-7)=0 is 1 and 7.

<h3>What is an Expression?</h3>

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

For the given expression, (x-1)(x-7), the value of x for which the expression will be equal to 0 can be found by equation the factors of the expression to 0. Therefore,

x-1 = 0

x = 1

and

x-7=0

x = 7

Hence, the value of x for which the expression (x-1)(x-7)=0 is 1 and 7.

State the domain and range and determine if it's a function?
Dmitriy789 [7]

Answer:

The domain is the set of all "x" values and the range is set of all "y" values in a set of ordered pairs. ... If each x-value corresponds with only one y-value, then the relation is a function.-by-step explanation:

The picture below shows Annie and her younger brother Tommy’s money. They want to combine their money to buy something together.
Inga [223]

Answer:

$5.47

Step-by-step explanation:

Given data:

Annie has 4 dollar , 11 dimes, 4 pennies.

Tommy has 3 dimes, 3 pennies.

To add the money, let us first convert dime and penny into dollar.

1 dollar = $1

11 dime = $1.1

4 penny = $0.04

3 dime = $0.3

3 penny = $ 0.03

Total money = Annie’s money + Tommy’s money

                     = $4 + $1.1 + $ 0.04 + $0.3 + $0.03

                     = $5.47

So, they have $5.47 in all.
