If the cos 0=3/5 use the Pythagorean identity to find sin 6
Oksanka [162]

The Pythagorean identity is

sin²Ф + cos²Ф=1

or

sin²Ф= 1- cos²Ф

Now in the problem we are given that

cos Ф=3/5

Now to find sin Ф, we can plug the value of cos Ф in the identity

So

sin²Ф= 1- cos²Ф = 1-(3/5)² = 1- 9/25 = (25-9)/25 = 16/25

Sin²Ф= 16/25

take square root on both sides

Now when we take square root on both sides we have to always remember that we will get one positive and one negative answer

So

Sin Ф = 4/5 or -4/5

trevor tutors french for $15 and hour and scoops ice cream for $10 an hour. he is going to work 15 hours this week. at least how
yaroslaw [1]
Total number of hours = 15

Let the hours spent tutoring french be x.

Therefore hours spent on scooping ice cream = (15 - x)

Amount:    Tutoring french is $15 an hour, total for x hours = 15x

For scooping ice cream  it is $10 an hour   10*(15 - x) = 150 - 10x

To make more than $180

15x  + (150 - 10x)  > 180

15x + 150 - 10x > 180

15x - 10x > 180 - 150

5x > 30

x > 30/5

x > 6

So he needs to tutor more than 6 hours in order to make more than $180
