The account balance resulting from a principal of P and an interest rate of r over t years is
A = P(1 +rt)
Substitute the given values and solve for t.
11424 = 5600(1 + .08t)
(11424/5600) -1 = .08t
1.04/.08 = t = 13

i) the least positive coterminal angle can be found by subtracting 2pi from your original angle. We subtract 2pi because 11pi/3 is larger than 2pi.
So: 11pi/3 - 2pi = 11pi/3 - 6pi/3 = 5pi/3 or 
ii) The reference angle is the smallest angle you can make with the x-axis. Since 5pi/3 is in Quadrant IV, the reference angle is found by:
2pi - 5pi/3 = 6pi/3 - 5pi/3 = pi/3 or 
iii) 5pi/3 or 300 degrees is found in Quadrant IV.
Answer:
x=
x=-
Step-by-step explanation:
I would agree with the answer of c, hope this helps
The would be -3,, because your doing y2-y1 over x2-x1
