Answer:

Step-by-step explanation:

He will have 0 because if he hit the first one, he gets 25 points and if he missed the 2nd time, he loses 25 points. So u do 25 - 25 to get 0 points.

Answer:

Seth will have 0 points

Step-by-step explanation:

He hit the target the first time at gained 25 points and then missed and lost 25 so 25-25=0

I hope this helped let me know if this is wrong

Have an amazing day:)

Use the surface integral in Stokes' Theorem to calculate the circulation of the field Bold Upper F equals x squared Bold i plus

Alinara [238K]

Answer:

The circulation of the field f(x) over curve C is Zero

Step-by-step explanation:

The function $f(x)=(x^{2},4x,z^{2})$ and curve C is ellipse of equation

$16x^{2} + 4y^{2} = 3$

Theory: Stokes Theorem is given by:

$I= \int \int\limits {{Curl f\cdot \hat{N }} \, dx$

Where, Curl f(x) = $\left[\begin{array}{ccc}\hat{i}&\hat{j}&\hat{k}\\\frac{∂}{∂x} &\frac{∂}{∂y} &\frac{∂}{∂z} \\F1&F2&F3\end{array}\right]$

Also, f(x) = (F1,F2,F3)

$\hat{N} = grad(g(x))$

Using Stokes Theorem,

Surface is given by g(x) = $16x^{2} + 4y^{2} - 3$

Therefore, tex]\hat{N} = grad(g(x))[/tex]

$\hat{N} = grad(16x^{2} + 4y^{2} - 3)$

$\hat{N} = (32x,8y,0)$

Now, $f(x)=(x^{2},4x,z^{2})$

Curl f(x) = $\left[\begin{array}{ccc}\hat{i}&\hat{j}&\hat{k}\\\frac{∂}{∂x} &\frac{∂}{∂y} &\frac{∂}{∂z} \\F1&F2&F3\end{array}\right]$

Curl f(x) = $\left[\begin{array}{ccc}\hat{i}&\hat{j}&\hat{k}\\\frac{∂}{∂x} &\frac{∂}{∂y} &\frac{∂}{∂z} \\x^{2}&4x&z^{2}\end{array}\right]$

Curl f(x) = (0,0,4)

Putting all values in Stokes Theorem,

$I= \int \int\limits {Curl f\cdot \hat{N} } \, dx$

$I= \int \int\limits {(0,0,4)\cdot(32x,8y,0)} \, dx$

I=0

Thus, The circulation of the field f(x) over curve C is Zero

SOLVE THIS PROBLEM! EXTRA POINTS!!!!!!!<br><br><br> 3025/5.5 = A/90.75

I am Lyosha [343]

Step-by-step.

30255.5=a90.75

Step 1: Cross-multiply.

30255.5=a90.75

(3025)*(90.75)=a*(5.5)

274518.75=5.5a

Step 2: Flip the equation.

5.5a=274518.75

Step 3: Divide both sides by 5.5.

5.5a5.5=274518.755.5

a=49912.5

A town has a population of 13000 and grows at 4.5% every year. To the nearest tenth of a year, how long will it be until the pop

ELEN [110]

Answer:

Correct answer: n = 5.96 ≈ 6 years

Step-by-step explanation:

Given:

Currently population P = 13,000

The percentage annual population growth is 4.5 % or in decimal notation

p = 1.045

Population after n years Pₙ = 16,900

Work:

After first year it will be P₁ = P · p

After second year it will be P₂ = P₁ · p = P · p²

After third year it will be P₃ = P₂ · p² = P · p³

.....................................................................................

After n-th year it will be Pₙ = P · pⁿ

pⁿ = Pₙ / P

n = log p (Pₙ / P) = ln (Pₙ / P) / ln p

n = ln (16,900/ 13,000) / ln 1.045 = ln 1.3 / ln 1.045 = 5.96 ≈ 6

If we accept n = 5.9 we will get:

Pₙ = P · pⁿ = 13.000 · 1.045⁵°⁹ = 16,855

If we accept n = 5.96 we will get:

Pₙ = P · pⁿ = 13.000 · 1.045⁵°⁹⁶ = 16,899.6

If we accept n = 6 we will get:

Pₙ = P · pⁿ = P₆ = P · p⁶ = 13.000 · 1.045⁶ = 16,929.38

What you will accept is yours choice.

God is with you!!!
