Find all values of $x$ such that $\sqrt{4x^2} - \sqrt{x^2} = 6$.
Eddi Din [679]

9514 1404 393

Answer:

  x = -6 or 6

Step-by-step explanation:

The square root is always positive, so the equation simplifies to ...

  \sqrt{4x^2}-\sqrt{x^2}=6\\\\2|x|-|x|=6\\\\|x|=6\\\\x=\{-6,\ 6\}

_____

The graph shows the solutions to f(x) = 0, where f(x) = √(4x²) -√(x²) -6.

there are four semi trailer trucks parked in a line at the rest stop after the first truck each truck in the line weighs 2 tons
alexira [117]
Call the weght of the first truck "w_{1}". We then know that the truck after that is 2 tons more, and the next and the next. i.e:
w_{2} = w_{1} + 2
w_{3} = (w_{2} + 2) = (w_{1}+4)
w_{4} = (w_{3} + 2) = (w_{1}+6)

We also know that total is 32 tons. 
w_{total} = 32 = (w_{1}) + (w_{2}) + (w_{3}) + (w_{4})
32 = (w_{1})+(w_{1}+2)+(w_{1}+4)+(w_{1}+6)
32= 4(w_{1})+12
20=4(w_{1})
w_{1} = 5 tons

Therefore the trukcs weigh 5,7,9 and 11 tons for a total of 32 tons.

Converting to pounds, the trucks weigh 10,000, 14,0000, 18,0000 and 22,000 pounds.

Can u help me here I have more the next one is part 2 for this question
Harlamova29_29 [7]

The circumference of the vase is 18.84 inches.

<u>Step-by-step explanation:</u>

The circumference of the cylinder is same as the circumference of its base.

Moreover, the base of the cylinder is actually a circle.

So we need to find the circumference of the circle to find the circumference of the cylinder.

From the given figure, we know that the diameter of the base d= 6 inches.

∴The formula for the circumference of the circle = 2πr or dπ.

⇒ circumference = 6×3.14.

                             = 18.84.

So the circumference of the circle is 18.84 inches.

∴The circumference of the cylindrical vase is also 18.84 inches.

Examine the data below for a stalk of corn. Logarithmic regression Use logarithmic regression to find an equation of the form y
masya89 [10]

The value of <em>a</em> and <em>b</em> for the data values of stalk of corn using the logarithmic regression is -76.2038 and 37.6735 respectively.

<h3>What is logarithmic regression?</h3>

Logarithmic regression is a type of regression which is used to model the statement in which the growth or decay initially at rapid rate, and then slow down with respect to time.

The data of the table for the day and height of the stalk of corn is listed below.

Day (<em>x</em>)                9    12    22    40    

Height (<em>y</em>) in        5    17    45    60  

Mean of x values,

m_x=\dfrac{9+12+22+40}{4}\\m_x=17.5581

Mean of y values,

m_y=\dfrac{5+17+45+60}{4}\\m_y=31.75

For the above table, the value of correlation coefficient is 0.99133. For these values, the logarithmic regression can be given as,

y = -76.2038+37.6735\ln(x)

Compare it with the following logarithmic regression equation, we get

y = a+b\ln(x)

a=-76.2038\\b=37.6735

Hence, the value of <em>a</em> and <em>b</em> for the data values of stalk of corn using the logarithmic regression is -76.2038 and 37.6735 respectively.
