Answer:

Price of the adult ticket is $13

Price of the child ticket is $3

Step-by-step explanation:

Lets x be the adult ticket and y be the child ticket.

Given:

School sold 14 adult tickets and 14 child tickets for a total of $224, so the first equation is.

14x+14y=224-------------(1)

And the school took in $44 on the  second day by selling 2 adult tickets and 6 child tickets, so the second equation is.

2x+6y=44---------------(2)

We find the price of an adult ticket and the  price of a child ticket by solving above system of equation.

Now, equation 2 multiplied by 7.

7(2x+6y=44)

14x+42y=308---------(3)

Now, equation 1 subtracted by equation 3.

14x+42y=308

14x+14y=224

-______________

14x is cancelled in both equations, so we get the equation.

28y=84

y=\frac{84}{28}

y = 3

Now, we substitute y = 3 in equation 2.

2x+6(3)=44

2x+18=44

2x=44-18

2x=26

x=\frac{26}{2}

x = 13

Therefore, the price of the adult ticket is $13 and the price of the child ticket is $3.

1. Write out the law of cosines and find the hypotenuse of triangle with 2 sides lengths equal to three and the included angle m
LUCKY_DIMON [66]

Answer:

1.) \sqrt{13.341}  ≈ 3.652

2.) I would say something about how the A in front of cos in the equation would change to 90, rather than stay 75 (in the equation for the step by step), but it would be easier to just use the Pythagorean theorem.

Step-by-step explanation:

I think we may have the same class so hopefully this helps:

1.) a^2 = b^2 + c^2 - 2bccosA --> law of cosines formula.

   a^2 = 3^2 + 3^2 - 2(3)(3)cos(75) --> plugged in numbers; when you draw the triangle, the included angle would be A, and the opposite side would be a. B and b, and C and c are opposite each other. In this case, a is the hypotenuse.

   a^2 = 18 - 18cos75 --> in between steps.

   a^2 = 13.341 --> more simplifying.

   a(hypotenuse) = \sqrt{13.341} or 3.652 --> answer

2.) This one is just an explanation: The 75 in the equation is the given angle, which is a. If this changes, it would just change in the equation too. And obviously, if it's 90 degrees, you can just use Pythagorean theorem a^2+b^2=c^2.

Good luck! :)

\\ \rm\Rrightarrow x^3(-2x^3+x-5)-3x(-2x^3+x-5)+4(-2x^3+x-5)

\\ \rm\Rrightarrow -2x^6+x^4-5x^3+6x^4-3x^2+15x-8x^3+4x-20

\\ \rm\Rrightarrow -2x^6+7x^4-13x^3-3x^2+19x-20

#b

Yes

It's because multiplication law states that ab=ba
