Answer:

$59.50

Step-by-step explanation:

Lets work out the equation for the given relationship.

This is a linear relationship.

Find the slope first:

(21.75 - 19.50)/(3 - 2) = 2.25

Use one pair of points to get the equation:

c - 19.50 = 2.25(m - 2)
c - 19.50 = 2.25m - 4.50
c = 2.25m + 15

We see the yearly fee is $15 and monthly rate is $2.25.

If we apply the changes to rates the equation becomes:

c = (2.25*2)m + (15 - 5) = 4.5m + 10

Find the cost of 11 months of membership:

c = 11*4.5 + 10 = $59.50

Answer:

well i think its over 103.10 because 11 months divide 2 fraction then take 1 carry or instead use calculator and type 0077239812 this binary!! and divide by 23 and thats the answer its only like decimals from the point!!

Answer:320 children and 262 adults swam in the public pool

Step-by-step explanation:

Let x represent the number of children that swam in the public pool.

Let y represent the number of adults that swam in the public pool.

582 people used the public swimming pool. This means that

x + y = 582

The daily prices are $1.50 for children and $2.00 for adults. The receipts for admission totaled to $1004.00. This means that

1.5x + 2y = 1004 - - - - - - - - - -1

Substituting x = 582 - y into equation 1, it becomes

1.5(582 - y) + 2y = 1004

873 - 1.5y + 2y = 1004

- 1.5y + 2y = 1004 - 873

0.5y = 131

y = 131/0.5 = 262

Substituting y = 262 into x = 582 - y, it becomes

x = 582 - 262 = 320

puteri [66]

Answer:

15 days

Step-by-step explanation:

Since he used both of the weights today, he will only do both on the day they come together.

weights: 3 days, 6 days, 9 days, 12 days, 15 days

machine: 5 days, 10 days, 15 days

Because the numbers both were the same on 15 days, then that is when he will do both of them

Use Stokes' Theorem to evaluate C F · dr where C is oriented counterclockwise as viewed from above. F(x, y, z) = 2yi + xzj + (x

Lady_Fox [76]

By Stokes' theorem, the line integral of $\vec F$ over $C$ is given by the surface integral of the curl of $\vec F$ over $S$ , where $S$ is the region of intersection of the plane $z=y+6$ and the cylinder $x^2+y^2=1$ with $S$ having positive/upward orientation.

Parameterize $S$ by

$\vec s(u,v)=u\cos v\,\vec\imath+u\sin v\,\vec\jmath+(u\sin v+6)\,\vec k$

with $0\le u\le1$ and $0\le v\le2\pi$ .

Take the normal vector to $S$ to be

$\vec s_u\times\vec s_v=-u\,\vec\jmath+u\,\vec k$

The curl of $\vec F$ is

$\nabla\times\vec F(x,y,z)=(1-x)\,\vec\imath-\vec\jmath+(z-2)\,\vec k$

Then the line integral is equivalent to

$\displaystyle\int_C\vec F\cdot\mathrm d\vec r=\iint_S(\nabla\times\vec F)\cdot\mathrm d\vec S$

$=\displaystyle\int_0^{2\pi}\int_0^1\bigg((1-u\cos v)\,\vec\imath-\vec\jmath+(u\sin v+4)\,\vec k\bigg)\cdot\bigg(-u\,\vec\jmath+u\,\vec k\bigg)\,\mathrm du\,\mathrm dv$

$=\displaystyle\int_0^{2\pi}\int_0^1(5u+u^2\sin v)\,\mathrm du\,\mathrm dv=\boxed{5\pi}$
