Step-by-step explanation:

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)

Answer:

The inverse reciprocal.

The slope of a perpendicular line is always the inverse reciprocal.

Answer:

Step-by-step explanation:

Slope-Intercept Form: y = mx + b

m - slope

b - y-intercept

The slope m of a perpendicular line is always the inverse reciprocal.

Therefore, our mperpendicular  is 3.

Answer:

[tex]\frac{x^{3}\sqrt[3]{x} }{4}[/tex]

Step-by-step explanation:

*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^

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.

Answer:

Step-by-step explanation:

2x + 3 + 4x + 2 + 2x - 1 = 180 (bc the sum of the angles of a triangle = 180)

8x = 176

x = 22

2x + 3 = 47

4x + 2 = 90

2x - 1 = 43

Step-by-step explanation:

The model shows cost is increasing at a rate of $80 dollars/pound.

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.

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
