Answer:
Well 7 x 10^-5 would mean you moved the decimal 5 Times because the power at the end of 10 is how many times the decimal is moved till it’s a number greater or equal to 1. So the scientific notation of that is: 0.00003
The -5 means that it was moved to the right. Positive always means left. Negative is always right.
Answer:
-9
Step-by-step explanation:
The other numbers are floating point numbers
Hi
we can write: f(x)= (x-2)^2
So for f(x+2), we replace x in f(x) by x+2
That means: f(x+2)= (x+2-2)^2=x^2.
Then the answer is x^2 and you are right.
Hope that you understand.
Answer:
9 square root of 7
Step-by-step explanation:
You’re going to break apart radical 28 into square root of 4 and square root of 7.
The square root of 4 is 2 so you add the 2 to the 3 and it equals 5 and since the square root of 7 can’t be simplified and it stays the same. So all you do is add 4 radical 7 and 5 radical 7 which equals 9 radical 7.
