Answer:
see explanation
Step-by-step explanation:
The error is in Step 1, by not adding 2 on the left side, that is
Given
7.7 = w - 2 ( add 2 to both sides )
7.7 + 2 = w - 2 + 2
9.7 = w
<span>if we take square root (x - 3)^2 + y^2
y = x^2
(x - 3)^2 + x^4
f(x) = x^4 + x^2 - 6x + 9.
first derivation:
f'(x) = 4x^3 + 2x - 6.
4x^3 + 2x - 6 = 0.
one solution is x = 1
second derivation
f"(x) = 12x^2 + 2
it is positive for x = 1
hope it helps

Answer: A.
Step-by-step explanation:
To find mean, average the numbers in the data set by adding them together and dividing by the number of values.
(96 + 77 + 82 + 91 + 89) / 5 = 87.
To find median, take the "middle" value of the data set. To find this, you can sort the numbers in ascending order and remove the same amount of values from each side.
77 / 82 / 89 / 91 / 96, the median is 89.
Therefore, the mean is less than the median.
3.75, 3.9, 4.256, 4.258, 4.5
So how do you find out? It is really easy.
First you look the the number, we all know 3 is less then 4 so the 3s go first
Then you look the tenths, the choices are 3.75 and 3.9. The tenth 9 and 7, and we all know 7 is less then 9, so 3.75 is the first one, then 3.9.
Now let's look at the 4s. The choices are 4.5, 4.258, and 4.256. The tenths are 5, 2, and 2. 2 is less then 5 so they go before 4.5.
Then we look at the hundredth, the choices are 4.256 and 4.258. Since they have same hundreds, we look at the thousands. They are 6 and 8. 6 is less then 8 so 4.256 go before 4.258.
