Mathematics
1 answer:
Strike441 [17]3 years ago
4 0

Answer:

a_{10} = \frac{5}{8}

Step-by-step explanation:

The n th term of a geometric sequence is

a_{n} = a_{1} r^{n-1}

Substitute in values

a_{10} = 320 × (\frac{1}{2}) ^{9}

                         = 320 × \frac{1}{512} = \frac{320}{512} = \frac{5}{8} = 0.625

Solve for x in the given interval.<br><br> sec x= -2√3/3, for π/2 ≤x≤π
drek231 [11]

Answer:

b. x=\frac{5\pi}{6}

Step-by-step explanation:

The given function is

\sec x=-\frac{2\sqrt{3} }{3},\:\:for\:\:\frac{\pi}{2}\le x \le \pi

Recall that the reciprocal of the cosine ratio is the secant ratio.

This implies that;

\frac{1}{\cos x}=-\frac{2\sqrt{3} }{3}

\Rightarrow \cos x=-\frac{3}{2\sqrt{3} }

\Rightarrow \cos x=-\frac{\sqrt{3}}{2}

We take the inverse cosine of both sides to obtain;

x=\cos^{-1}(-\frac{\sqrt{3}}{2})

x=\frac{5\pi}{6}
