x^5 (x^3)^3
= x^5*x^9 (Since (a^m)^n = a^mn)
= x^5+9 (Since a^m*a^n = a^m+n)
= x^14
Therefore: x^5(x^3)^3 = x^14
Answer:
C.
There is no repeated x or y values
We know that a relation is a function, when each input of x value gives exactly one output of y-value.
In a function two or more x-coordinates can give same y-value, but one x-value cannot give two y-values.
We can see that in our given set each x-value corresponds to exactly one y-value, therefore, the given set represents a function.
Step-by-step explanation: Hopefully this helped, if not HMU and I will get you a better answer

I'm guessing we have
S1 = 1000
S2 = 1000 + 500
S3 = 1000 + 500 + 250
S4 = 1000 + 500 + 250 + 125
S5 = 1000 + 500 + 250 + 125 + 62.5
Just adding that up, S5 is
Answer: 1937.5
Do they want you to use the geometric series formula? We'll check it that way.
We have first term a=1000 and common ratio r=1/2. In general
For us that's
S5 = (1000 (1 - (1/2)^5))/(1 - 1/2) = 2000(1 - 1/32)
= 2000(31)/32 = 62000/32 = 1937.5 √
Math works!
