Answer:

Step-by-step explanation:

x=r cos \theta=7 cos150=7cos(180-30)=-7cos ~30=-\frac{7\sqrt{3} }{2} \\y=r~sin~\theta=7~sin ~150=7~sin~(180-30)=7~sin~30=\frac{7}{2} \\so ~coordinates ~are~(-\frac{7\sqrt{3}}{2} ,\frac{7}{2} )\\C

atroni [7]

Step-by-step explanation:

10\% \: of \: x =  39

\frac{10}{100} x = 39

\frac{1}{10} x = 39

x = 39 \times 10 = 390

Therefore , the no. is 390

Write the expression in terms of sine and cosine and simplify so that no quotients appear in the final expression. Show work.
AlexFokin [52]
<h3>Answer:</h3>

sec²(x)

<h3>Explanation:</h3>

As required:

... = (sin²(x)/cos²(x))(1 +(cos²(x)/sin²(x))

... = (sin²(x)·(sin²(x)+cos²(x)) / (cos²(x)·sin²(x))

... = 1/cos²(x) = sec²(x)

_____

Alternatively, multiply out the given expression, then use trig identities.

... = tan²(x) + (tan(x)·cot(x))² = tan²(x) +1 = sec²(x)
