Elena-2011 [213]

1. $\dfrac{9}{25}$ of students ride the bus to school. Note that

$\dfrac{9}{25}=\dfrac{9\cdot 2}{25\cdot 2}=\dfrac{18}{50}.$

2. $\dfrac{19}{50}$ of students walk to school.

3. The fraction of students that ride the bus or walk to school is

$\dfrac{18}{50}+\dfrac{19}{50}=\dfrac{18+19}{50}=\dfrac{37}{50}.$

Answer: the fraction of students that ride the bus or walk to school is $\dfrac{37}{50}.$

The point (1,-1) is on the terminal side of angle theta in standard position what are the values of sine cuisine and tangent of

pickupchik [31]

$\bf \textit{terminal point }\implies 
\begin{array}{lclcll}
(&1&,&-1)\\
&\uparrow &&\uparrow \\
&x&&y
\end{array}
\\\\\\
sin(\theta)=\cfrac{y}{r}
\qquad 
% cosine
cos(\theta)=\cfrac{x}{r}
\qquad 
% tangent
tan(\theta)=\cfrac{y}{x}\\\\
-----------------------------\\\\
\textit{so, what's the radius "r"?}\implies r^2=x^2+y^2\implies r=\sqrt{x^2+y^2}$
