Answer:
See explanation and proof below.
Step-by-step explanation:
For this case we want to proof this identity:
And we need to us the double angle formula given by:
If we use a substitution for example we see that the double angle formila is given by:
And we got:
And if we apply sqaure root on both sides we got:
And that complete the proof
Answer:
96 points
Step-by-step explanation:
Because each question is worth more than the previous one, a student would obtain the highest score answering only 8 questions by skipping the first two and answering questions 3-10. Question 3 is worth 5 points and each question is worth 2 more points than the previous one, so if you got questions 3-10 right you'd get 5 + 7 + 9 + 11 + 13 + 15 + 17 + 19 = 96 points.
