Use the formula,
I = Prt
P = Principal amount = 400
I = interest = 18
r = annual rate
t = time in years = 9/12 = 3/4
so,
18 = 400*r*3/4
r = 0.06
so the annual interest rate is 0.06 or 6%.
Answer:
{x | x ≥ 0}
Step-by-step explanation:
We have the function, 
.
Now, for the square root function, the values inside the square root must be positive.
Here, we have that the values of 'x' must be greater than or equal to 0.
i.e. x ≥ 0.
Hence, the domain of the function is {x | x ≥ 0}.
Arc length, (s)=(radius, r)(central angle, q)
s=rq
q=s/r
q=4/10
q=2/5, or 0.4 radians
To determine his gross pay, we need the amount of money he earns per hour and the rate of overtime per hour since he exceeded 40 hours of work. But since the rate for his overtime was not given. A general expression is what the most I can do. It is as follows:
Gross pay = 13.40(49) + overtime rate(9)
Hope this helps. Have a nice day.
