If sin theta = -5/7 , which of the following are possible?
Sav [38]

Solution:

we are given that

sin \theta=-5/7

As we know that

cos \theta =\sqrt{1-sin^2 \theta}  \\

Substitute the value we get

cos \theta=\sqrt{1-(\frac{-5}{7})^2}  \\
\\
cos \theta=\sqrt{1-(\frac{25}{49})}  \\
\\
cos \theta=\sqrt{(\frac{24}{49})} =\frac{\sqrt{24}}{7}\\

Since sec \theta=\frac{1}{cos \theta}\\

So here sec \theta=\frac{7}{\sqrt{24}}\\

As we know that

tan \theta=\frac{sin \theta}{cos \theta}\\
\\  \text{Substitute the values we get}\\
\\
tan \theta=\frac{-5/7}{\frac{\sqrt{24}}{7}}\\
\\
tan \theta=\frac{-5}{\sqrt{24}}\\

Hence the correct option is C.

How many cube roots does 0.216 have explain
fgiga [73]

Answer:

0.216 has exactly one cube root, which is 0.6.

Step-by-step explanation:

Note that the third root of 0.216 is 0.6, obtained on a calculator by typing in 0.216^(1/3).  Verify this root by cubing 0.6:  0.6*0.6*0.6 = 0.216.  Thus, 0.216 has exactly one cube root.

The number of CDs sold in 2010 was 114 million, down from 147 million the previous year. Find the Absolute and relative (percent
sesenic [268]

Answer:

Absolute decrease = 33 million

Relative decrease = 22.45%

Step-by-step explanation:

The number of CD's sold the previous year (2009) was 147 million, and in 2010 it was 114 million. The absolute decrease is 147 million -114 million = 33 million.

The relative decrease is just the percent decrease and it is:

33 million/147 million =22.45% decrease.
