.Evaluate the line integral ∫C F⋅dr where F= 〈−4sinx, 4cosy, 10xz〉 and C is the path given by r(t)=(2t3,−3t2,3t) for 0 ≤ t ≤ 1
∫C F⋅dr = ...........

Answers

Answer 1

The value of the line integral ∫C F⋅dr = 1.193.

To evaluate the line integral ∫C F⋅dr, we first need to calculate F⋅dr, where F= 〈−4sinx, 4cosy, 10xz〉 and dr is the differential of the vector function r(t)= (2t^3,-3t^2,3t) for 0 ≤ t ≤ 1.

We have dr= 〈6t^2,-6t,3〉dt.

Thus, F⋅dr= 〈−4sinx, 4cosy, 10xz〉⋅ 〈6t^2,-6t,3〉dt

= (-24t^2sin(2t^3))dt + (-24t^3cos(3t))dt + (30t^3x)dt

Now we integrate this expression over the limits 0 to 1 to get the value of the line integral:

∫C F⋅dr = ∫0^1 (-24t^2sin(2t^3))dt + ∫0^1 (-24t^3cos(3t))dt + ∫0^1 (30t^3x)dt

The first two integrals can be evaluated using substitution, while the third integral can be directly integrated.

After performing the integration, we get:

∫C F⋅dr = 2/3 - 1/9 + 3/5 = 1.193

Therefore, the value of the line integral ∫C F⋅dr is 1.193.

In conclusion, we evaluated the line integral by calculating the dot product of the vector function F and the differential of the given path r(t), and then integrating the resulting expression over the given limits.

(x^2+3x^2-kx-24)÷(x+3) what's the value of k??​

Answers

Answer:

-4

Step-by-step explanation:

since x+3 is a factor of the polynomial (x^2+3x^2-kx-24), then;

x+3 = 0

x = -3

Substitute x = -3 into the polynomial

x^2+3x^2-kx-24 = 0

(-3)^2+3(-3)^2-(-3)k-24 = 0

9 + 27 + 3k - 24 = 0

36-24 + 3k = 0

12 = -3k

k = -12/3

k = -4

Hence the value of k is -4

The team won 18 of its 30 games. What was the team’s won-lost ratio?

Answers

Answer:

18:12 (accurate)

3:2 (simplified)

Step-by-step explanation:

The team won 18 games out of 30 total games. Find the amount of games lost by simply subtracting 18 with 30:

30 - 18 = 12

The ratio you are trying to find is won to lost, or won:lost. Plug in the corresponding numbers to the corresponding terms:

won:lost ⇒ 18:12

18:12 is the ratio.

If the teacher asks you to simplify, factor both sides. Divide 6 from both sides:

(18)/6 : (12)/6

3:2

3:2 is your simplified ratio.

Bert is driving along a country road at a constant speed of 30 miles per hour. How long does it take for him to travel 50 miles?

Answers

30 miles/60 minutes = 50 miles/ x minutes
Cross multiply, and you have 3000 = 30x. x = 100 minutes, or 1 hour 40 minutes

The time of 1 hour 40 minutes Bert takes for him to travel 50 miles.

What is the distance?

Distance is defined as the product of speed and time.

What are Arithmetic operations?

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.

The operator that performs the arithmetic operation is called the arithmetic operator.

Operators which let do a basic mathematical calculation

+ Addition operation: Adds values on either side of the operator.

For example 4 + 2 = 6

- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.

for example 4 -2 = 2

* Multiplication operation: Multiplies values on either side of the operator

For example 4*2 = 8

Given that Bert is driving along a country road at a constant speed of 30 miles per hour

To determine the time it takes for him to travel 50 miles.

Let the time of x minutes it takes for him to travel 50 miles.

⇒ 30 miles/60 minutes = 50 miles/ x minutes

Cross multiplication apply in above equation,

⇒ 30x. x = 60x50

⇒ 3000 = 30x.

⇒ x = 100 minutes, or

1 hour 40 minutes

Answers

Answer:

Length of tape required to wrap 12 presents is 48 centimeters.

Length of tape required to wrap 7 presents = 28 centimeters

Length of tape required to wrap 1 present = [tex]\frac{28}{7}=4[/tex] centimeters

Therefore,

Length of tape required to wrap 12 presents = 12 × Length of tape required to wrap 1 present

= 12 × 4
