use the exact value of cos 11pi/6 and the half-angle identity for sine to find the exact value of sin 11pi/12

Answers

Recall that

\sin^2x=\frac{1-\cos2x}2

So you have

\sin^2(11\pi)/(12)=\frac{1-\cos\frac{11\pi}6}2=\frac{1-(\sqrt3)/(2)}2=\frac{2-\sqrt3}4

This means

\sin(11\pi)/(12)=\frac{√(2-\sqrt3)}2

where you take the positive square root because \sin x must be positive for angles x in the interval 0<x<\pi.

Step-by-step explanation:

In your biology class, your final grade is based on several things: a lab score, scores on two major tests, and your score on the final exam. There are 100 points available for each score. However, the lab score is worth 21% of your total grade, each major test is worth 25%, and the final exam is worth 29%. Compute the weighted average for the following scores: 60 on the lab, 81 on the first major test, 69 on the second major test, and 79 on the final exam. Enter your answer as a whole number.

Answers

Answer:

Weighted\ Average =  73

Step-by-step explanation:

Given

Lab = 21\%

Tests = 25\%

Exam = 29\%

Lab\ Score = 60

First\ Test = 81

Second\ Test = 69

Exam = 79

Required

The weighted average

To do this, we simply multiply each score by the corresponding worth.

i.e.

Weighted\ Average =  Lab\ worth * Lab\ score + Tests\ worth * Tests\ score.....

So, we have:

Weighted\ Average =  21\% * 60 + 25\% * 81 + 25\% * 69 + 29\% * 79

Using a calculator, we have:

Weighted\ Average =  73.01

Weighted\ Average =  73 --- approximated
