4. (10 points) From the given triangle:
katrin2010 [14]

Answer:

sinθ =  y/r        sinθ = \frac{-6}{10} = \frac{-3}{5}

cosθ =  x/r       cosθ = \frac{8}{10} = \frac{4}{5}

tanθ =  y/x       tanθ =  \frac{-6}{8} =\frac{-3}{4}

cscθ =  r/y       cscθ = \frac{-5}{3}

secθ =  r/x       secθ =  \frac{5}{4}

cotθ = x/y       cotθ = \frac{4}{3}

explanation:

r = \sqrt{(8)^{2}+(-6)^{2}  }

r = 10

x = 8

y = -6

r = \sqrt{(4)^{2}+(3)^{2}  }

r = 5

x = 4

y = 3

The school that Stefan goes to is selling tickets to a choral performance on the first day of ticket sales the school sold three
Serggg [28]

The price of 1 senior citizen ticket is $ 8

<em><u>Solution:</u></em>

Let "x" be the price of 1 senior citizen ticket

Let "y" be the price of 1 child ticket

<em><u>The school sold three senior citizen tickets and one child ticket for a total of $38</u></em>

Therefore, we frame a equation as:

three senior citizen tickets x price of 1 senior citizen ticket + one child ticket x price of 1 child ticket = 38

3 \times x + 1 \times y = 38

3x + y = 38 --------- eqn 1

<em><u>The school took an $52 on the second day by selling three senior citizen tickets and two child tickets</u></em>

Therefore, we frame a equation as:

three senior citizen tickets x price of 1 senior citizen ticket + two child ticket x price of 1 child ticket = 52

3 \times x + 2 \times y = 52

3x + 2y = 52 ---------- eqn 2

<em><u>Solve eqn 1 and eqn 2</u></em>

<em><u>Subtract eqn 1 from eqn 2</u></em>

3x + 2y - 3x - y = 52 - 38

<h3>y = 14</h3>

<em><u>Substitute y = 14 in eqn 1</u></em>

3x + y = 38

3x + 14 = 38

3x = 24

<h3>x = 8</h3>

Thus the price of 1 senior citizen ticket is $ 8
