How much would $120 invested at 6% interest compounded monthly be worth after 21 years? Round your answer to the nearest cent.
A(t)= P(1+r/n)^nt

$421.72

Step-by-step explanation:

Compounded Monthly Interest Rate Formula: A = P(1 + 4/12)^12t

Simply plug in our known variables:

A = 120(1 + 0.06/12)²¹⁽¹²⁾

A = 120(1.005)²⁵²

A = 120(3.51437)

A = 421.724

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi

i think da answer is

d.square root of 3
