Log_(10)(x² - 4x + 7) = 2
Take the base 10 anti log of both sides.
x² - 4x + 7 = 10² = 100
x²- 4x - 93 = 0
Quadratic Formula
x = [4 ± √(4²-4(1)(-93))]/[2(1)] = [4 ± 2√97)]/2 = 2 ± √97
Answer:
3/4
Step-by-step explanation:
5 3/8 - 4 5/8
We need to borrow from the whole number
5 becomes 4 and the one becomes 8/8
4 + 8/8+ 3/8 - 4 5/8
4 11/8 - 4 5/8
Subtract the fractions
6/8
Simplify the fractions
3/4
Answer:
Non Response: In conducting a survey some people did not respond to our survey, this sometimes affects our survey result very much.
For Example: It can happen that some people may refuse to participate in a survey, as the question asked to people contain personal detail or illegal activities or asking any embarrassing information, so people refused to participate in the survey. This non-response cause the results of the survey to be biased
Answer:
The answer is 5a-35.
Step-by-step explanation:
So, since you told me to explain, if a number is right next to a parentheses without any signs you multiply it.
But instead of doing 5 times 7a, you multiply both of them separately.
5 times a is pretty much just 5a. 5 times -7 is -35.
As a result, you will be left with 5a-35.
If you have anymore questions, let me know.
