Emma loans $4,225 to a friend and charges them 15% interest, compounded annually. How much interest will Emma's friend pay her back if it takes 2 years?

2 x^2 -3x+p

sum of roots = 3/2

let other root be x

3+ x = 3/2

x= 3/2 - 3 = -3/2

product of roots = p/2

3× -3/2 = p/2

-9 = p

⭐⭐

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1
