Answer:
Step-by-step explanation:
We are asked to write $125 billion in scientific notation.
1 billion equals $1,000,000,000.
To write a number in scientific notation, we need two factors such that one is between 0 and 10 and 2nd is a power of 10.
The first number would be 1.25.
Now, we can see that there are 11 digits after decimal, therefore, we will multiply 1.25 by 10 raised to 11th power as:
Therefore, our required number would be .

Complete the table for the function y = 0.1^x
The first step: plug values from the left column into the ‘x’ spot in the formula <u>y=0.1^x</u>.
* 0.1^-2 : We can eliminate the negative exponent value by using the rule a^-1 = 1/a. Keep this rule in mind for future problems. (0.1^-2 = 1/0.1 * 0.1 = 100).
* 0.1^-1 = 1/0.1 = 10
* 0.1^0 = 1 : (Remember this rule: a^0 = 1)
* 0.1^1 = 0.1
Our list of values: 100, 10, 1, 0.1
Now, we can plug these values into your table:
