Answer:

64w^4 - 48w^2 + 9

Step-by-step explanation:

(I rearranged the terms so I could solve it easier)

Expanding the square:

(-8w^2 + 3)^2

(-8w^2 + 3)(-8w^2 + 3)

Combining like terms:

64w^4 - 24w^2 - 24w^2 + 9

64w^4 - 48w^2 + 9

Final answer: 64w^4 - 48w^2 + 9

Answer: x = 108

Step-by-step explanation: In this problem, we're given a diagram and

we're asked to find the value of x that would make m ll n.

We can see that the angles that are marked in the diagram

are same-side interior angles since they lie on the same side

of the transversal and they lie on the interior of lines m and n.

Therefore, in order for line m to be parallel to line n,

these angles must be supplementary.

In other words, they must add to 180 degrees.

So we can setup the equation x + 72 = 180.

Subtracting 72 from both sides gives us x = 108.

So the value of x that would make line m ll n is 108.

===============================================

Explanation:

Highlight the path that starts with A and then leads to D

Multiply the values highlighted to get 0.5*0.6 = 0.3

Effectively we've computed the following

P(A and D) = P(A)*P(D given A)

P(A and D) = 0.5*0.6

P(A and D) = 0.3

The notation "D given A" indicates we know event A has happened. We cannot simply say P(D) because there is another event D that happens on the lower branch B; so instead we say P(D given A). You can replace the word "given" with a vertical bar to write P(D | A), though in my opinion the vertical bar could be easily mistaken for the uppercase letter i, a lowercase letter L, or the numeric digit "one". I find its easier to describe what is going on rather than use the vertical bar notation.

A buyer would have to pay $533.45 for an article whose marked prices $567.50.

Step-by-step explanation:

Marked price = $567.50

Discount=6%

Price after discount = 567.50 - 6% of 567.50

                                  [tex]=\:567.50\:-\frac{6}{100}\:\times \:567.50[/tex]

                                   [tex]=567.5-34.05[/tex]

                                    [tex]=533.45[/tex] $

Therefore, a buyer would have to pay $533.45 for an article whose marked prices $567.50.

Answer:

38 units (rounded off to the nearest unit)

Step-by-step explanation:

The perimeter of the given figure will be 38 units.

Its the sum of length of the sides used to made the given figure.

We are given that Measures of three linear sides as 5, 10, 10, 5 units.

Radius of the circular part = 5 units

Since Perimeter of a polygon = Measure of the circumference of the polygon

The Perimeter of the figure = measure of the three straight lines + measure of the circumference of the quarter circle

Thus Measure of linear sides = 5 + 10 + 10 + 5 = 30 units

Circumference of the quarter circle =  2πr

=  2π(5)

= 7.85 units

Perimeter of the figure = 30 + 7.85

                                     = 37.85

                                     ≈ 38 units

Therefore, the perimeter will be 38 units.

Annelies Marie "Anne" Frank was a German-born Jewish girl who kept a diary in which she documented life in hiding under Nazi persecution. She is a celebrated diarist who described everyday life from her family hiding place in an Amsterdam attic.

Given are excerpts from Anne Frank's diary and play version.

I would prefer the play version of excerpts from Anne Frank's Diary as watching a play is better than reading because the characters come to life, as does the way they relate to and interact with each other.

Answer:

The quotient of: [tex]\frac{2.64\cdot 10^{-3}}{8.0\cdot 10^0}[/tex] is: [tex]\mathbf{3.3\times 10^{-4}}[/tex]

Step-by-step explanation:

We need to find quotient of: [tex]\frac{2.64\cdot 10^{-3}}{8.0\cdot 10^0}[/tex]

We know that [tex]10^0=1[/tex]

Now solving:

[tex]\frac{2.64\cdot 10^{-3}}{8.0\cdot 10^0}\\=\frac{2.64\cdot 10^{-3}}{8.0}\\=\frac{0.00264}{8}\\=0.00033[/tex]

Writing it in scientific notation

[tex]0.00033\\=3.3\times10^{-4}[/tex]

So, the quotient of: [tex]\frac{2.64\cdot 10^{-3}}{8.0\cdot 10^0}[/tex] is: [tex]\mathbf{3.3\times 10^{-4}}[/tex]

(0, -2) and (1, 1) both work in this system of equations.

Step-by-step explanation:

Happy to help! The best way to find if it is a solution is to look for those points on the graph. When we graph the point, it needs to fall in an area where both lines or shaded or on a solid line.  

Look carefully and see if you can find points like these!

(0, -2) falls on a solid line.  

(1, 1) falls in the double shaded area.

Therefore, (0, -2) and (1, 1) both work in this system of equations.

Step-by-step explanation:

A = Surface area of the Earth = [tex]1.5\times 10^8\ \text{km}^2[/tex]

Total number of people on Earth = 7.594 billion as of 2018 = [tex]7.594\times 10^9[/tex]

We need to find the number of people living in each square km of land area.

So, we need to divide the number of people by the land area of the Earth.

[tex]1.5\times 10^8\ \text{km}^2=7.594\times 10^9\ \text{people}[/tex]

[tex]\Rightarrow 1\ \text{km}^2=\dfrac{7.594\times 10^9}{1.5\times 10^8}[/tex]

[tex]\Rightarrow 1\ \text{km}^2=50.63\approx 51\ \text{people}[/tex]

So, 51 people will inhabit each square km of land area.

Answer:

[tex]y-\frac{1}{3} =\frac{3}{4} (x-4)[/tex]

Step-by-step explanation:

To see which equations have the slope of 3/4, we just need to focus on the right half of the equations to see what the multiplier of x is.

Equations 1 and 3 can be eliminated because they have a slope of [tex]\frac{1}{3}[/tex] and 4 respectively.

Now we can decide between 2 and 4 by plugging in the point [tex](4,\frac{1}{3})[/tex] to see which works properly.

Simplify equation 2

[tex]y-\frac{1}{3} =\frac{3}{4} (x-4)\\\\y-\frac{1}{3} =\frac{3}{4}x-3\\\\y=\frac{3}{4}x-\frac{8}{3}[/tex]

Plug in the point

[tex]\frac{1}{3} =\frac{3}{4}(4)-\frac{8}{3} \\ \\\frac{1}{3} =3-\frac{8}{3} \\\\\frac{1}{3} =\frac{9}{3} -\frac{8}{3} \\\\\frac{1}{3} = \frac{1}{3}[/tex]

This checks out, so equation 2 is your answer.

The rounding number of 10676 nearest 100 is 10,700.

What is Rounding number?

To making a number simpler but keeping its value close to what it was, is called Rounding.

Given that;

The number is 10,676

Now, To round the number nearest to the 100 , we check the tens digit ,if the digit is equal to 5 or more then round up, and if the number is less than 5 then its round down.

Here, In the number 10,676 the digit in the tens place is 7 which is more than 5, so we can round up.

Hence, The rounding number = 10,700

Thus, The rounding number of 10676 nearest 100 is 10,700.
