How do you write 0.0000248 in scientific notation?
2 answers:
Step-by-step explanation: To write a number in scientific notation, first write a decimal point in the number so that there is only one digit to the left of the decimal point.
In this case, In this case, there is already a decimal point in the number and notice there is only one digit to the left of it.
Now, we need to count the number of places the decimal point would need to move in order to get to a number that is between 1 and 10.
In this case, we would need to move the decimal point 5 places in order to get to the number 2.48 which is a number between 1 and 10.
To get from 2.48 back to 0.0000248, we would need to move the decimal point five places top the left which gives us an exponent of -5. Lastly, we multiply 2.48 by 10 to the -5th power.
Therefore, 0.0000248 can be written in scientific notation as 2.48 x

Correct Question:
Which term could be put in the blank to create a fully simplified polynomial written in standard form?
Options
Answer:
Step-by-step explanation:
Given
Required
Fill in the missing gap
We have that:
From the polynomial, we can see that the power of x starts from 3 and stops at 0 while the power of y is constant.
Hence, the variable of the polynomial is x
This implies that the power of x decreases by 1 in each term.
The missing gap has to its left, a term with x to the power of 3 and to its right, a term with x to the power of 1.
This implies that the blank will be filled with a term that has its power of x to be 2
From the list of given options, only can be used to complete the polynomial.
Hence, the complete polynomial is:
