Answer: cos(13pi/36)
Step-by-step explanation: just did the assignment
Answer:
1-cos2A/sin2A
=(1-cos^2 A+sin^2 A)/(2sinAcosA)
=(sin^2 A+sin^2A)/2sinAcosA
=2sin^2 A/2sinAcos^2 A
=sinA/cosA
=tanA
Answer:
If you are being bullied you should tell someone immediately so they can help you stand up to that bully. I know this isn't your answer but you should take this seriously.
Step-by-step explanation:
t = 15 + x and t = 5 + 2x represents the system of equations for this real world situation
<em><u>Solution:</u></em>
<em><u>Workout Gym has a sign up fee of $15 and charges $1 per day for membership</u></em>
Therefore,
Sign up fee = $ 15
Charge per day = $ 1
Let "x" be the number of days charged for membership
Let "t" be the total charge for membership
<em><u>Thus, we frame a equation as:</u></em>
Total fee = sign up fee + charge per day (number of days)
Total fee = 15 + 1(x)
t = 15 + x ------- eqn 1
<em><u>Healthy Gym has a $5 sign up fee and charges a $2 daily fee</u></em>
Sign up fee = $ 5
Charge per day = $ 2
Let "x" be the number of days charged for membership
Let "t" be the total charge for membership
<em><u>Thus, we frame a equation as:</u></em>
Total fee = sign up fee + charge per day (number of days)
t = 5 + 2(x)
t = 5 + 2x ------- eqn 2
Thus eqn 1 and eqn 2 represent the system of equations for this situation
