X²+v=w (move v to w)
x²=w-v
x=√w-v (then square root w-v)

Substract v to both sides of the equation: x^2+v-v = w-v
you get x^2=w-v
Now take the square root of both sides: root(x^2) = root(w-v)
you get x= sq root (w-v) or x= +/- sq root(w-v)

Answer:

Option c

Step-by-step explanation:

Best Fit Regression Model

When experimental data is collected, scientists frequently ask themselves if there is a relationship between some of the variables under study. It's crucial in modern times where artificial intelligence technology is trying to find key answers where traditional approaches hadn't before.

One of the most-used tools to find relations between variables is the regression model and its best fit lines to try to find an expression who relates variable x (years from 1960) and variable y (minimum wage requirement) as of our case.

The provided data was entered into a digital spreadsheet and an automatic function was applied to find the best-fit model.

We found this equation:

$y=0.11363x+0.6906$

when rounded to three decimal places, we find

$y=0.114x+0.691$

Which corresponds to the option c.

Thank you for the help guys! Find m ABC

Akimi4 [234]

Vertical angles are equal

7x - 19 = 4x + 2
7x - 4x = 2 + 19
3x = 21
x = 21/3
x = 7

m∠ABC = 4x + 2 = 4*7 + 2 = 28 + 2 = 30°

Tom's school report must be more than 12 pages, he writes at the rate of a half a page a day.

soldi70 [24.7K]

Answer:

24 days (or more)

Step-by-step explanation:

I assume you want to figure out how long it will take Tom to write the minimum amount of pages for his school report at that rate?

Since Tom writes 1/2 a page a day and he must write 12 or more pages, then it will take him 2 days to write one page, thus, 24 days to write 12 pages.

Therefore, Tom needs at least 24 days to write his school report.

sertanlavr [38]

Answer:

Height = 6000 m

Step-by-step explanation:

$Volume = length \times breadth \times height \\\\480000 = 10 \times 8 \times height\\\\480000 = 80 \times height\\\\height = \frac{480000}{80} = 6000 \ m$
