Answer:
Step-by-step explanation:
Compound interest:
The compound interest formula is given by:
Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.
$12000 cash
This means that 
Compounded at 4% interest annually.
This means that 
What equation will calculate the value in x years?
Answer:
-36864
Step-by-step explanation:
100 ÷ 10=10
(a)=a
(46-5x6) power 3=16
9x16 power 3 =36864
10-36864
=-36864
Answer:
let the third side be x
using pythagoras theorem we get
(7)^2+(6)^2=(x)^2
49+36=x^2
√(85)=x
x=9.21
Answer:
C. And the reference angle is pi/3
Step-by-step explanation:
Let me give you a little quick way to do this. You’re probably trying to memorize the unit circle and figure out what 2pi/3 equals. However, all you need is a bit of math.
Start with the denominator and multiply the numerator by its correct angle
Anything with 3 in it’s denominator, is a multiple of a 60 degree angle. The numerator is 2 so do 60 x 2, which equals 120. Your angle is 120 and will land in the top left quadrant.
Moving on to the reference angle. Think of this as being what you have left on the horizontal axis. The angle took up 120 degrees. Now find the rest. 180 - 120 = 60. Pi/3 equals 60 degrees
