Just took the test ;)
Square root numbers are always irrational.
0 = rational.
-1/16 is rational.
Function for compound interest:
Amount = Initial amount * ( 1 + (r/n) ) ^ (nt)
where r = interest rate per year, n = period per year
n = 2, r = 0.01
Answer: F(t) = 2,800 * [ 1 + (0.01/2) ] ^ 2t
Answer:x + 5y is greater than or equal too $50
Step-by-step explanation:
If x is equal to the amount of $1 then there is no need for a coefficient. Being that y is represented as $5 there needs to be a coefficient of because it’s five dollars times however many you have. Then it is greater than or equal to $50 because the problem states there is at least $50 in the register.
