Given cos theta = - 2/5 and sin theta < 0, find the six trigonometric values. I need help with this

Lena [83]

Answer:

$\sin\,\theta =-\frac{\sqrt{21} }{5}$

$\tan\,\theta =\frac{\sqrt{21} }{2}$

$\sec\,\theta = \frac{-5}{2}$

$cosec\,\theta =\frac{-5}{\sqrt{21} }$

$\cot\,\theta =\frac{2}{\sqrt{21} }$

Step-by-step explanation:

$\cos\theta =\frac{-2}{5}$

As both $sin\,\theta$ ,

$\theta$ lies in the third quadrant.

In the third quadrant,

$\sin\theta$

$\sin\,\theta =-\sqrt{1-\cos^2\,\theta} \\=-\sqrt{1-(\frac{-2}{5})^2 } \\\\=-\sqrt{1-\frac{4}{25} }\\\\=-\sqrt{\frac{25-4}{25} }\\\\=-\frac{\sqrt{21} }{5}$

$\tan\,\theta = \frac{\sin\,\theta}{\cos\,\theta }\\\\=\frac{\frac{-\sqrt{21} }{5} }{\frac{-2}{5} }\\\\=\frac{\sqrt{21} }{2}$

$\sec\,\theta =\frac{1}{\cos\,\theta }\\\\=\frac{1}{\frac{-2}{5} }\\\\=\frac{-5}{2}$

$\ cosec \,\theta = \frac{1}{sin\,\theta }\\\\=\frac{1}{\frac{-\sqrt{21} }{5} }\\\\=\frac{-5}{\sqrt{21} }$

$\cot\,\theta =\frac{1}{\tan\,\theta}\\\\=\frac{1}{\frac{\sqrt{21} }{2} }\\\\=\frac{2}{\sqrt{21} }$

What is the ratio 16 to 40 written as a fraction in lowest terms? plz help 50 points

Luda [366]

Answer:- $\frac{2}{5}$

Step-by-step explanation:

The given ration is 16 :40

In fraction, the above ratio can be written as : $\frac{16}{40}$

To write the above fraction in lowest terms, we need to divide the numerator and the denominator by the greatest common divisor.

Since, $16=2\times8\\40=5\times8$ , Hence, 8 is the greatest common divisor of 16 and 40.

Now, divide the numerator and denominator by 8, we get

$\frac{16}{40}=\frac{2}{5}$

Matilda mixed 8 parts cranberry juice with 4 parts apple juice to make cran-apple juice. what is the ratio of cranberry juice to

Paladinen [302]

The ratio of cranberry juice to apple juice is 2:1 or 2 to 1

Both 8 and 4 can be divided by 4 so divide (cranberry juice—>) 8 by 4 to get 2. Divide (apple juice—>) 4 by 4 to get 1, now put them in the correct spot which equals 2:1 or 2 to 1
