Given cos 0 = 3/5 and 0 is in Quadrant I, what is the value of tan 0 ?

4 / 3

Step-by-step explanation:

cos θ = 3 / 5

cos 53 = 3 / 5

θ = 53

tan θ = sin θ / cos θ

sin 53 = 4 / 5

tan 53 = sin 53 / cos 53

= ( 4 / 5 ) / ( 3 / 5 )

= ( 4 / 5 ) x ( 5 / 3 )

= ( 4 x 5 ) / ( 5 x 3 )

tan 53 = 4 / 3

ROI is 75% .

Step-by-step explanation:

Formula

As given

Andrew invested $20,000 in mutual funds and received a sum of $35,000 at the end of the investment period.

Final value of investment = $35000

Initial value of investment = $20000

Put all the values in the formula

ROI = 75%

Therefore ROI is 75% .
