Answer:

1/4th

Step-by-step explanation:

This comes from knowing the unit circle in both radians and degrees. However, you could also calculate it from knowing that 360 degrees is 2\pi radians. What you'll find is that \frac{\pi }{2} radians is 90 degrees, or 1/4th of the circle. This means that an arc measuring \frac{\pi }{2} radians will be 1/4th of the entire circumference.

I hope this helps!

Suppose you decide to put $12,500 in an account earning 9% interest compounded quarterly. How much interest would you earn after
Vesnalui [34]

Step-by-step explanation:

you add 9% to a number by multiplying that number by 1.09.

because adding 9% gives us in the end 109% of the original amount.

anyway, the formula for quarterly compounded interest is

Cq = P [ (1+r)^(4*n) – 1 ]

P is the starting principal amount

r is the interest rate per quarter (= interest rate / 4)

n would be the number of years (= 1 in our case).

so, the interest after 1 year is

12500((1 + 0.09/4)⁴ - 1) = 12500(1.0225⁴ - 1) =

= 12500 × 0.093083319 = $1,163.541485 ≈ $1,163.54
