Step-by-step explanation:

what is the problem here you don't understand ?

you understand the words "equality" and "inequality" ?

this is all about the question, if something is equal to something else or not - meaning of they are the same or at least the same size.

an expression without an equal ("=") or unequal sign ("<", ">", ">=", "<=", "<>" - if you don't understand these symbols, please ask, they are simply basic keyboard symbols for the scientific symbols) is not any form of that - no equality, and no inequality.

so,

1. is NOT

2. is NOT because it has an equality symbol

3. is a quadratic inequality (when doing the multiplication of both bracket terms, there will be an x×x=x² part) - it has a ">" (greater) symbol

4. is a quadratic inequality (there is a x² term as highest power of x included) - it has a "<=" (smaller or equal) symbol

5. is a quadratic inequality (there is a x² term as highest power of x included) - it has a ">" (greater) symbol

A cylinder shaped can needs to be constructed to hold 400 cubic centimeters of soup. The material for the sides of the can costs

LenKa [72]

Answer:

The dimensions of the can that will minimize the cost are a Radius of 3.17cm and a Height of 12.67cm.

Step-by-step explanation:

Volume of the Cylinder=400 cm³

Volume of a Cylinder=πr²h

Therefore: πr²h=400

$h=\frac{400}{\pi r^2}$

Total Surface Area of a Cylinder=2πr²+2πrh

Cost of the materials for the Top and Bottom=0.06 cents per square centimeter

Cost of the materials for the sides=0.03 cents per square centimeter

Cost of the Cylinder=0.06(2πr²)+0.03(2πrh)

C=0.12πr²+0.06πrh

Recall: $h=\frac{400}{\pi r^2}$

Therefore:

$C(r)=0.12\pi r^2+0.06 \pi r(\frac{400}{\pi r^2})$

$C(r)=0.12\pi r^2+\frac{24}{r}$

$C(r)=\frac{0.12\pi r^3+24}{r}$

The minimum cost occurs when the derivative of the Cost =0.

$C^{'}(r)=\frac{6\pi r^3-600}{25r^2}$

$6\pi r^3-600=0$

$6\pi r^3=600$

$\pi r^3=100$

$r^3=\frac{100}{\pi}$

$r^3=31.83$

r=3.17 cm

Recall that:

$h=\frac{400}{\pi r^2}$

$h=\frac{400}{\pi *3.17^2}$

h=12.67cm

The dimensions of the can that will minimize the cost are a Radius of 3.17cm and a Height of 12.67cm.

50 POINTS IF YOU ANSWER CORRECTLY!

melisa1 [442]

Answer:

Problem 4: Option C, 32

Problem 5: You need to have the 2 and the x combine. Make the table 2x than 16.

Problem 6: x = 17

Problem 7: She drew a 2, x and an 16. Instead you must have 2x and 16. 2x + 16 = 50

Step-by-step explanation:

Problem 4

2 + x + 16 = 50

x + 18 - 18 = 50 - 18

x = 32

Answer: Option C, 32

Problem 5

You need to have the 2 and the x combine. Make the table 2x than 16.

Answer: You need to have the 2 and the x combine. Make the table 2x than 16.

Problem 6

2x + 16 - 16 = 50 - 16

2x / 2 = 34 / 2

x = 17

Answer: x = 17

Problem 7

She drew a 2, x and an 16. Instead you must have 2x and 16. 2x + 16 = 50

Answer: She drew a 2, x and an 16. Instead you must have 2x and 16. 2x + 16 = 50
