Evaluate (if possible) the six trigonometric functions of the real number. (If not possible, enter IMPOSSIBLE.)

kotegsom [21]

$\sin(t) = \frac{1}{2} 
\\
\\ \cos(t) = - \frac{ \sqrt{3} }{2} 
\\
\\ \tan(t) = \frac{\sin(t)}{\cos(t)}= - \frac{1}{ \sqrt{3} } 
\\
\\ \csc(t) = \frac{1}{\sin(t)}= 2 
\\
\\ \sec(t) =\frac{1}{\cos(t)}=- \frac{2}{ \sqrt{3}} 
\\
\\ \cot(t) = \frac{1}{\tan(t)}=- \sqrt{3}$

Identify the slope and y-intercept of 3/5 - 1/3 x

Rudiy27

Your 3/5 - (1/3)x is an expression, not an equation. You must write out the entire equation in question:

"Identify the slope and y-int. of y = 3/5 - (1/3)x."

The y-intercept is obvious: It's 3/5.

The slope is (1/3).

Solve for r<br> rs / a - 3 = k

Jobisdone [24]

You can isolate r to one side of the equation by dividing by adding three, dividing by s, multiplying by a and you get:

r=a(3+k)/s

. You and a friend have dinner at a restaurant . Your meal costs $15.85 and you leave an 18% tip and your friend's meal cost $14

Allushta [10]

Answer:

$1.54

Step-by-step explanation:

18% of $15.85 is 2.853, so your total is $18.703

20% of $14.30 is 2.86, so their total is $17.16

So the difference is $1.543, rounded (since your dealing with money) would be $1.54
