<h3>Answer:  Choice B</h3>

\frac{\sqrt{91}}{10}

sqrt(91)/10

========================================

Work Shown:

Angle \theta is in Q1 since 0 \le \theta \le 90

\sin \theta = \frac{3}{10}

\sin^2 \theta = \left(\frac{3}{10}\right)^2 = \frac{9}{100}

\cos^2\theta = 1-\sin^2\theta

\cos^2\theta = 1-\frac{9}{100}

\cos^2\theta = \frac{100}{100} - \frac{9}{100}

\cos^2\theta = \frac{91}{100}

\cos\theta = \sqrt{\frac{91}{100}} .... cosine is positive in Q1

\cos\theta = \frac{\sqrt{91}}{\sqrt{100}}

\cos\theta = \frac{\sqrt{91}}{10}

If the first 4 terms of an infinite geometric sequence are 150, 120, 96, and 76.8, then the sum of all the terms in the sequence
hammer [34]

The sum of the sequence is 750

<h3>How to determine the sum of the series?</h3>

The series is given as:

150, 120, 96, and 76.8,

Start by calculating the common ratio using:

r = T2/T1

This gives

r = 120/150

r = 0.8

The sum of the series is then calculated as:

S = \frac{a}{1 - r}

This gives

S = \frac{150}{1 - 0.8}

Evaluate

S = 750

Hence, the sum of the sequence is 750
