12) A new amusement park decides to offer its visitors a choice between two plans. With Plan 1 they pay $6 to enter

astraxan [27]

9514 1404 393

Answer:

3 rides
$16.50

Step-by-step explanation:

The plan 1 cost for x rides will be ...

y = 6 + 3.50x

The plan 2 cost for x rides will be ...

y = 12 + 1.50x

These costs will be equal when ...

y = y

6 + 3.50x = 12 + 1.50x . . . . . substitute for y

2.00x = 6 . . . . . . . . . . . . . subtract 6+1.50x

x = 3 . . . . . . . . . . . . . . . divide by 2

For 3 rides, the cost will be the same.

For 3 rides the cost is ...

y = 6 + 3.50(3) = 6 + 10.50 = 16.50

The cost for 3 rides will be $16.50 for either plan.

5. Find the vertex and length of the latus rectum for the parabola.

olga55 [171]

Answer: (2,5)

Step-by-step explanation:

To find the x coordinate of the vertex, you will set x-2=0 and solve for x

x-2=0

+2 +2

x = 2

Now since we know the vertex has an x coordinate of 2 we have to solve for y by plotting in the x value.

y= 1/2(2-2)^2 + 5

y = 0 +5

y =5

Convert the line integral to an ordinary integral with respect to the parameter and evaluate it. modifyingbelow integral from no

vovangra [49]

Parameterize $C$ by

$\vec r(t)=(1-t)(0,0,0)+t(1,3,6)=(t,3t,6t)$

with $0\le t\le1$ . Then the line integral is

$\displaystyle\int_Cxyz\,\mathrm dS=\int_0^1x(t)y(t)z(t)\left\|\frac{\mathrm d\vec r}{\mathrm dt}\right\|\,\mathrm dt$

$=\displaystyle18\sqrt{91}\int_0^1t^3\,\mathrm dt=\boxed{\frac{9\sqrt{91}}2}$
