What is Algebra?

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

We given C gives the cost, in dollars, to shred w pounds of confidential documents of a company.

Also, the modeled equation :C’(500)=80

which shows that for 500 pounds of documents, the cost is increasing at a rate of $80 dollars/pound.

Hence, one pound costs $80.

How do you do this question?

Answers

Answer:

(a) y = ¼ sin(x² + C)

(b) y = ¼ sin(x²)

Step-by-step explanation:

(a) dy/dx = ½ x √(1 − 16y²)

dy / √(1 − 16y²) = ½ x dx

4 dy / √(1 − 16y²) = 2x dx

sin⁻¹(4y) = x² + C

4y = sin(x² + C)

y = ¼ sin(x² + C)

(b) When x=0, y=0.

0 = ¼ sin(C)

C = 0

y = ¼ sin(x²)

What this is saying is it is taking the cubed root (which is like a square root, except it is using a 3 instead of 2) of x to the power of 10 divided by 64.

The equation is also saying:

[tex]\frac{\sqrt[3]{x^{10} }}{\sqrt[3]{64} }[/tex]

We can simplify the bottom half of the fraction to be 4. The cube root of something is essentially saying its the number times itself 3 times (in this case, divided by that original number). The number to get to 64 was 4 and it was done like this: 4 times 4 times 4 (which equals 64).

As for the top equation, it will simplify down to [tex]x^{3} \sqrt[3]{x}[/tex].

Since [tex]x^{10}[/tex] can be broken up to be x and [tex]x^{9}[/tex], we cube root the [tex]x^{9}[/tex] to become [tex]x^{3}[/tex], while the x remains the same.

We come to result of [tex]\frac{x^{3}\sqrt[3]{x} }{4}[/tex], which is the answer.

There are 36 squares on each red and white checkered tablecloth. How many squares are there on 7,011 tablecloths? huryyyyyyyyyyyyyyyyyyy plz :(

Answers

252396 squares i think

Multiplying means adding a value a given number of times to zero

The number of squares in 7,011 tablecloths is 252,396 squares

The above number of squares in 7,011 tablecloths is correct for the following reason:

The known number of squares on each red and white checkered tablecloth = 36 squares

Required:

The number of squares in 7,011 tablecloths

Solution;

To find the number of squares on the 7,011 tablecloths, we have;

Number of squares in a given number of units of tablecloth = Number of squares per unit of tablecloth × Number of tablecloths

∴ Number of squares in 7,011 tablecloths = 36 squares × 7,011 tablecloth

Number of squares in 7,011 tablecloths = 36 squares × 7,011 tablecloth = 252,396 squares

The number of squares in 7,011 tablecloths = 252,396 squares

The old man had been drinking, and in that state wandered away, and was found by some peasants, who carried him to their king, Midas. Midas recognized him, and treated him hospitably, entertaining him for ten days and nights with an unceasing round of jollity.[2] On the eleventh day he brought Silenus back, and restored him in safety to his pupil. Whereupon Bacchus offered Midas his choice of a reward, whatever he might wish. He asked that whatever he might touch should be changed into gold. Bacchus consented, though sorry that he had not made a better choice.[3] Midas went his way, rejoicing in his new-acquired power, which he hastened to put to the test. He could scarce believe his eyes when he found a twig of an oak, which he plucked from the branch, become gold in his hand. He took up a stone; it changed to gold. He touched a sod; it did the same. He took up an apple from the tree; you would have thought he had robbed the garden of the Hesperides. His joy knew no bounds, and as soon as he got home, he ordered the servants to set a splendid repast on the table. Then he found to his dismay that whether he touched bread, it hardened in his hand; or put a morsel to his lip, it defied his teeth. He took a glass of wine, but it flowed down his throat like melted gold.[4] In consternation at the unprecedented affliction, he strove to divest himself of his power; he hated the gift he had lately coveted. But all in vain; starvation seemed to await him. He raised his arms, all shining with gold, in prayer to Bacchus, begging to be delivered from his glittering destruction. Bacchus, merciful deity, heard and consented. "Go," said he, "to River Pactolus, trace its fountain-head, there plunge yourself and body in, and wash away your fault and its punishment." He did so, and scarce had he touched the waters before the gold-creating power passed into them, and the river sands became changed into gold, as they remain to this day.Select two key details that could be included in a summary of the myth.A. Bacchus sent Midas to the river to wash away his golden touch.B. Bacchus sometimes found his teacher Silenus missing.C. Midas could not eat because of the wish Bacchus granted.D. Midas entertained Silenus in his kingdom for ten days.E. Silenus was found by peasants and carried to Midas. Jeremy's password is the combination of letters and numbers shown below.
