Make sure you use the full value of Pi to get the most accurate answer, not just 3.14!

1 ticket =.5
12=.42
25=.40
50=.5
120=.42
I would suggest that they constantly lower the rate per ticket as the number of tickets increases so for example
1t=.5/ticket
12t=.42/ticket
25t=.38/ticket
50t=.35/ticket
120t=.30/ticket

QuestionIn PQR, sin P = 1/3, sin R = 2/3,and p = 9. Find the side length r.

mamaluj [8]

Lets draw our triangle:

Lets use the "Law of Sines" to find our side r:

$\frac{p}{\sin P}=\frac{r}{\sin R}\rightarrow\frac{9}{\frac{1}{3}}=\frac{r}{\frac{2}{3}}\rightarrow9\times\frac{3}{1}\times\frac{2}{3}=r\rightarrow r=18$

So r=18

HELP ME PLZZ !!!!! I need help with this!!!

Answer: -40 - 180

Step-by-step explanation: So we have -40 feet below sea level at 2:15P.M. Notice at 2:16P.M it says 180 feet LOWER. This means if we subtract -40 feet by negative 180 feet, the answer would become -220 feet below sea level. Since we're writing an equation to express the answer, it would be -40 - 180 = -220.

Match the one-to-one functions with their inverse functions.

Nady [450]

The inverse of a function is obtained by making x the subject of the formular of the function.

Given the function
$f(x)= \frac{x}{8} -7$
the inverse of the function is obtained as follows:
$y= \frac{x}{8} -7 \\ \\ y+7=\frac{x}{8} \\ \\ x=8(y+7) \\ \\ \bold{f^{-1}(x)=8(x+7)}$

Given the function
[tex[f(x)=x+7[/tex]
the inverse of the function is obtained as follows:
$y=x+7 \\ \\ x=y-7 \\ \\ \bold{f^{-1}(x)=x-7}$

Given the function
$f(x)=1- \frac{x}{3}$
the inverse of the function is obtained as follows:
$y=1- \frac{x}{3} \\ \\ -\frac{x}{3} =y-1 \\ \\ x=-3(y-1) \\ \\ \bold{f^{-1}(x)=-3(x-1)}$

Given the function
$f(x)=20-0.25x$
the inverse of the function is obtained as follows:
$y=20-0.25x=20- \frac{1}{4} x \\ \\ \frac{1}{4} x=20-y \\ \\ x=4(20-y) \\ \\ \bold{f^{-1}(x)=4(20-x)}$
