No 3/47 is not a rational number because 3/47=0.063829787 which is non repeating so it is not rational. Hope this helps! :)
Answer: 14n + 6
Step-by-step explanation: Product is multiplication so 14 times a number or n is 14n, increased by 6 so 14n+6
Answer:
The range of the function is 
.
Step-by-step explanation:
Let 
. From Function Theory we must remember that the range of function corresponds to the set of images associated to each elemenf from domain. In this case, the function has a domain composed of three elements and we need to find the image of each element:
x = -2
x = -1
x = 2
The range of the function is .

Answer:
945x^3·y^16
Step-by-step explanation:
The 5th term will be ...
C(7,4)(3x)^3(y^4)^4 = 35·27·x^3·y^(4·4)
= 945x^3·y^16
_____
The coefficients of the expansion are C(n, k) where n is the exponent of the binomial, and k+1 is the term number. This is n!/(k!(n-k)!). The general (k-th) term of the expansion (a+b)^n is C(n, k)a^(n-k)b^(k) where k ranges from 0 to n.
