Trigonometric Identities and Applications? help

Vadim26 [7]

$\bf h=-15cos\left( \frac{2\pi }{5}t \right)\qquad \boxed{h=8}\qquad 8=-15cos\left( \frac{2\pi }{5}t \right)
\\\\\\
\cfrac{8}{-15}=cos\left( \frac{2\pi }{5}t \right)\implies cos^{-1}\left( \frac{8}{-15}\right)=cos^{-1}\left[ cos\left( \frac{2\pi }{5}t \right) \right]
\\\\\\
cos^{-1}\left( \frac{8}{-15}\right)=\cfrac{2\pi }{5}t\implies \cfrac{5}{2\pi }\cdot cos^{-1}\left( \frac{8}{-15}\right)=t\\\\
-------------------------------$

$\bf cos^{-1}\left( \frac{8}{-15}\right)=\stackrel{radians}{\stackrel{II~quadrant}{\approx 2.13}~~,~~\stackrel{III~quadrant}{\approx 4.15}}\qquad \qquad 
t=
\begin{cases}
\frac{5}{2\pi }\cdot 2.13\\\\
\frac{5}{2\pi }\cdot 4.15
\end{cases}$

Help please with my "science" hw everything relates to math ugh

sergeinik [125]

1. 3.0 mL * (1 L )/((1000 mL) = 0.003 L

2. 0.24 dag * (10 g)/(1 dag) * (1000 mg)/(1 g) = 2,400.0 mg

3. 1350.0 mm * (1 m)/(1000 mm) = 1.35 m

4. 20.0 kg * (1000 g)/(1 kg) = 20,000.0 g

5. 0.4 cL * (1 L)/(100 cL) * (1 hL)/(100 L) = 0.00004 hL

6. 310.0 m * (1 km)/(1000 m) = 0.31 km
