Determine tan(t) if cos(t)= -3/5 and sin(t) >0

kupik [55]

$\bf cos(\theta)=\cfrac{adjacent}{hypotenuse}
\qquad 
% tangent
tan(\theta)=\cfrac{opposite}{adjacent}\\\\
-------------------------------\\\\
cos(t)=-\cfrac{\stackrel{adjacent}{3}}{\stackrel{hypotenuse}{5}}$

now, the hypotenuse is just a radius unit, so, is never negative, so, the fraction is negative because the numerator is negative, that is, the adjacent side is -3.

now, let's use the pythagorean theorem to find the opposite side.

$\bf \textit{using the pythagorean theorem}\\\\
c^2=a^2+b^2\implies \pm\sqrt{c^2-a^2}=b\qquad 
\begin{cases}
c=hypotenuse\\
a=adjacent\\
b=opposite\\
\end{cases}
\\\\\\
\pm\sqrt{5^2-(-3)^2}=b\implies \pm\sqrt{25-9}=b\implies \pm 4=b$

ok... so, which is it? the +/-? well, we also know that <span>sin(t) >0, namely that the sine of the angle is positive, so, then is +4 then.

</span> $\bf tan(\theta)=\cfrac{opposite}{adjacent}\qquad \qquad tan(t)=\cfrac{4}{-3}\implies \boxed{tan(t)=-\cfrac{4}{3}}$ <span>
</span>

Harvard University accepts 6 students for every 100 applicants. How many students will be accepted in 850 applicants apply for a

LenKa [72]

Answer:

51 students.

Step-by-step explanation:

First you need to establish a rate 6/100+3/50

8*100=800 6*8=48

3/50

850-800=50 3/50

48+3=51
