9 less than a number is <em><u>9 - n</u></em>
Where n is that number
Answer:
Step-by-step explanation:
In order to convert 0.0004578, which is in decimal, to scientific notation, all we need to do in this case is to move our decimal point to the right till we arrive at the first number that is not a zero, and then eliminate all the zero.
In this case, we will have to move the decimal point 4 spaces to our right, which would mean our exponent would be negative. The number of decimal spaces we moved to our right would be the value of our exponent, which is -4 in this case.
Thus, we have:

Answer: B
Step-by-step explanation:
The range of a function is the set of all possible values for the function's dependent variable. In this case, that variable is y, so we can look at the graph to observe what possible y-values fit in the range.
There are no y-values below -1 on the chart, and the function goes upwards to infinity, so the correct answer is B, y is greater than or equal to -1.

Answer:
-6
-6i
6i
6
Step-by-step explanation:
1) √4 . √-3 . √-3


-6
2) √-4 . √-3 . √-3
.
Therefore,
- 6i
3) √4 . √3 . √-3


6i
4) √4 . √3 . √3


Therefore, √4 . √3 . √3 = 2 . 3 = 6
