Answer:
C
Step-by-step explanation:
Because, you have to move the decimal 7 times and to get it to 871, you have to move it over 2 times so there will be 5 zeros at the end because 2+5=7

Explanation:
If y has an exponent of 2, 4, 6, etc (basically any even number) then it leads to having inputs with multiple outputs.
Consider something like y^2 = x. If x = 100, then y = 10 or y = -10 are possible. A function can only have exactly one y output for any valid x input. Similar issues happen for things like y^4 = x and so on. So this is why A and C are not functions.
The other equations do not have y values with such exponents, so we can solve for y and have each x input lead to exactly one y output. Therefore, they are functions.
Answer:
18^5
Step-by-step explanation:
18^9 ÷ 18^4
= 18 ^ (9-4)
= 18 ^ 5
Answer:
2 * 10^2 times
Step-by-step explanation:
Given:
Population of Bloomington = 2.4 * 10^6
Population of Smallville = 12000
How many times greater is the population of Bloomington than Smallville ;
Population of Bloomington / Population of Smallville
2.4 * 10^6 / 12000
2.4 * 10^6 / 1.2 * 10^4
= 2 * 10^(6 - 4)
= 2 * 10^2
= 2 * 10^2 times
