What is a rational number ?
If p and q are any two numbers where q is not equal to 0, then the fraction in form p/q is called as rational number.
Let's check which of the given numbers are rational numbers.
A.
The number is √15.
= 3.8729
As , the number has non - terminating decimal , so , √15 is an irrational number.
B.
√16
= 4
As , this number is an integer and we can write it in form of fraction as , so , √16 is a rational number.
C.
√17
= 4.12310
As , the number has non - terminating decimal , so , √17 is an irrational number.
D.
√18
= 4.2426
As , the number has non - terminating decimal , so , √18 is an irrational number.
Therefore , the correct option is B that is square root of 16 i.e., 4 is a rational number.

Answer:
$13,952.30
Step-by-step explanation:
refer to attached graphic
the formula for compound interest is given as
A = P [ 1 + (r/n) ] ^ (nt)
where
A = final amount (we are asked to find)
P = principal amount = $13,500
r = rate = 3.3% = 0.033
n = 12 (compounded monthly)
t = 1 year
substituting these values into the equation
A = 13500 [ 1 + (0.033/12) ] ^ [(12)(1)]
A = 13500 [ 1 + 0.00275 ] ^ 12
A = 13500 [1.00275 ] ^ 12
A = 13500 (1.0335)
A = $13,952.30
