evaluate x^2/y^4/3 ds where c is the curve x=t^2 y=t^3 from 1

Answers

Answer 1

The value of the line integral is:

[tex](1/27) (49^{(3/2)} - 13^{(3/2)})[/tex]

≈ 36.724

To evaluate the line integral:

[tex]\int C x^2/y^{(4/3)} ds[/tex]

C is the curve given by x = t² and y = t^3, and ds is the element of arc length along the curve.

We can parameterize the curve as:

r(t) = (t², t³), 1 ≤ t ≤ ∛2

Then the tangent vector to the curve is:

r'(t) = (2t, 3t²)

The length of the tangent vector is:

|r'(t)| = √(4t² + 9t⁴ = t√(4 + 9t²)

So, the element of arc length ds is:

ds = |r'(t)| dt = t√(4 + 9t²) dt

The integral becomes:

[tex]\int C x^2/y^{(4/3)} ds[/tex]

=[tex]\int(1 to 3\sqrt 2) (t^4)/(t^{(8/3)}) (t\sqrt{(4 + 9t^2)}) dt[/tex]

= [tex]\int (1 to 3\sqrt 2) t^{(2/3)}\sqrt (4 + 9t^2) dt[/tex]

To evaluate this integral, we can make the substitution u = 4 + 9t²:

u = 4 + 9t²

du/dt = 18t

dt = du/(18t)

The limits of integration become:

u(1) = 13

u(∛2) = 49

The integral becomes:

[tex]\int C x^2/y^{(4/3)} ds[/tex]

= [tex](1/18) \int (13 to 49) u^{(1/2)} du[/tex]

=[tex](1/27) (49^{(3/2)} - 13^{(3/2)})[/tex]

So, the value of the line integral is:

[tex](1/27) (49^{(3/2)} - 13^{(3/2)})[/tex]

≈ 36.724

Elena is ordering dried chili peppers and corn husks for her cooking class. Chili peppers cost $16.95 per pound and corn husks cost $6.49 per pound.

Elena spends less than $50 on d pounds of dried chili peppers and h pounds of corn husks.

Can Elena purchase 1.5 pounds of dried chili peppers and 3 pounds of corn husks and spend less than $50? Explain your reasoning.

Answers

Yes she can. If she buy 1.5 pounds of dried chili peppers and 3 pounds of corn husks they will cost $45 so yes she will spend less than $50

Yes, Elena purchase 1.5 pounds of dried chili peppers and 3 pounds of corn husks and spend less than $50.

What is the reference as the equation?In its most basic form, an equation is an assertion that demonstrates that two formulas are equal. 63x + 5 = 14, for example, is an equation wherein 63x + 5 and 14 are two representations separated by a 'equal' sign.

For the given question;

Let the pounds of dried chili peppers be 'd'.Let pounds of corn husks be 'h'.Chili peppers cost $16.95 per pound Corn husks cost $6.49 per pound.

The equation becomes;

16.95 d + 6.49 h

16.95 (1.5) + 6.49 (3)

  25.425 + 19.47

        44.895 < $50

Thus, Elena purchase 1.5 pounds of dried chili peppers and 3 pounds of corn husks and spend less than $50.

A five feet tall man casts a shadow rhat is 4 1/3 feet long. A telephone pole casts a shadow that is 25.5 feet long. How tall is the telephone pole in inches

Answers

Answer:

22.1 inches

Step-by-step explanation:

The shadow is formed at a specific factor of the original image hence if a 5 feet tall man casts a shadow rhat is 4 1/3 feet long then a  telephone pole casts a shadow that is 25.5 feet long must have a length

5 / 4 1/3 = x / 25.5

where x is the length of the pole

5 / 13/3 = x/ 25.5

15/13 = x/25.5

cross multiply

15 * x = 13 * 25.5

Divide both sides by 15

x = 13 * 25.5 / 15

x = 22.1 inches

The telephone pole in inches is 22.1 long

Sam wants to make a sketch of the white house with a scale factor of 2 inches to 15 feet. She knows that the white house is about 85 feet wide and 152 feet long. What will the width and height of her model be?

Answers

Answer: The width of the model = 11.33 inches and the height of the model = 20.27 inches.

Step-by-step explanation:

Given: Scale factor:  2 inches in model =  15 feet in actual.

White house is about 85 feet wide and 152 feet long.

Width of model = [tex]\dfrac2{15}\times85=\dfrac{34}{3}=11.33\text{ inches}[/tex]

Height of model = [tex]\dfrac{2}{15}\times152\approx20.27\text{ inches}[/tex]

Hence, the width of the model = 11.33 inches and the height of the model = 20.27 inches.

How do I expand this

Answers

Step-by-step explanation:

We have

[tex](sc^2x-1)^2[/tex]

Which is the same as

[tex](sc^2x-1)(sc^2x-1)[/tex]

To expand this polynomial, we can use the FOIL method. Meaning that we multiply the Fronts, Outsides, Insides, and Lasts together and then add each of these products.

The two fronts are [tex]sc^2x[/tex] and [tex]sc^2x[/tex],

[tex](sc^2x )(sc^2x )=s^2c^4x^2[/tex]

The two Outsides are [tex]sc^2x[/tex] and [tex]-1[/tex],

[tex](sc^2x )(-1)=-sc^2x[/tex]

The two Insides are [tex]-1[/tex] and [tex]sc^2x[/tex],

[tex](-1)(sc^2x )=-sc^2x[/tex]

The two lasts are [tex]-1[/tex] and [tex]-1[/tex],

[tex](-1)(-1)=1[/tex]

Speed is the time rate at which an object is moving along a path,

Given that car traveling at an average rate of 60 miles per hour will drive 270 miles in 4.5 hours.

We have to check whether the statement is true or false.

To check, we can use the formula:

distance = rate x time

Substituting the given values, we get:

distance = 60 x 4.5 = 270 miles

Therefore, the statement is true.
