Inever learned how to do this in my class, halp : c

We will start with basic trigonometric equation

(sinΘ)Λ2+ (cosΘ)Λ2=1  First we divide whole equation with (cosΘ)Λ2

and get (tanΘ)Λ2 + 1 =1/(cosΘ)Λ2 we know that tanΘ=sinΘ/cosΘ

(tanΘ)Λ2= 1/(cosΘ)Λ2 - 1 => (tanΘ)Λ2=(- 13/5)Λ2 -1 => (tanΘ)Λ2= 169/25 - 1

(tanΘ)Λ2= (169-25)/25= 144/25 => tanΘ= + -√144/25= 12/5

We have chosen a positive solution because the sinΘ<0

The correct answer is tanΘ=12/5

Good luck!!!

i believe the correct answer is b.

this is the formula: v = the value of investment at the end of the time period

p = the principal amount (the initial amount invested)

r = the annual interest rate

n = the annual frequency of compounding (how many times a year interest is added)

t = the number of years the money is invested

^ means raise to the power of
