Answer:adult=75

Students = 200

Children=75

Step-by-step explanation:

Let x= adult tickets, y=students, z=child

x+y+z =350

Since x=z

y+2z= 350 -----------1

20x +12y + 10z = 4650

Since y=z

12y +30z = 4650 --------2

Using elimination method to solve eqn 1&2

Multiply eqn 1 by 12

12y + 24z = 4200

12y +30z = 4650

Subtract equ 2 from 1

-6z =-450

z=75, x = 75

y=350 -(75+75)

y= 200 tickets

You need a 30-year, fixed-rate mortgage to buy a new home for $225,000. your bank will lend you the money at an apr of 5.5 perce
bulgar [2K]
Loan amount, P = 225000
interest = 5.5%/12  per month
Monthly payment, A = 1000

At the end of 30 years, 
Future value of loan (with zero repayment)
F1=225000*(1+.055/12)^(30*12)
=1167162.264

Future value of repayment, A=1000 per month
F2=\frac{A((1+i)^n-1)}{i}
=\frac{1000((1+.055/12)^{360}-1)}{.055/12}
=913611.893

Therefore balloon payment
= F1-F2
=1167162.264-913611.893
=253550.37   (to the nearest cent)

Find the remainder for (x^10 + x^9 +...+x+1) divided by (x^2 - 1)
Assoli18 [71]

Since x^2-1=(x-1)(x+1), by the remainder theorem we have

\dfrac{p(x)}{x-1} = q(x) + \dfrac{p(1)}{x-1} = q(x) + \dfrac{11}{x-1}

where p(x) = x^{10}+x^9+\cdots+x+1.

Then

\dfrac{p(x)}{x^2-1} = q^*(x) + \dfrac{q(-1)}{x+1} + \dfrac{11}{x^2-1} = q^*(x) + \dfrac{q(-1)(x-1) + 11}{x^2-1}

The only missing piece is <em>q(x)</em>, which we can get through usual polynomial division:

\dfrac{x^{10}+x^9+\cdots+x+1}{x-1} = \underbrace{x^9 + 2x^8 + 3x^7 + \cdots + 9x + 10}_{q(x)} + \dfrac{11}{x-1}

so that

q(-1) = (-1)^9 + 2(-1)^8 + \cdots + 9(-1) + 10 = 5

Then the remainder we want is

\dfrac{p(x)}{x^2-1} = q^*(x) + \dfrac5{x+1} + \dfrac{11}{x^2-1} = q^*(x) + \dfrac{5(x-1)+11}{x^2-1} = q^*(x) + \dfrac{\boxed{5x+6}}{x^2-1}
