Emily says she can prove the Pythagorean Theorem using the following diagram. She explains that she can divide the squares on the two shorter sides into grids with equal-sized grid squares. She says she can then rearrange the grid squares to cover the area of the square on the hypotenuse, which proves that the sum of the squares on the two shorter sides equals the square on the hypotenuse. A 3 by 3 square, a 4 by 4 square, and a 5 by 5 square, put together to form a right triangle with legs 3 and 4 and hypotenuse 5. Is this a valid geometrical proof that a2 + b2 = c2 for all right triangles? Yes, because there are 9 grid squares on one side, 16 grid squares on the other side, and 25 grid squares on the hypotenuse, and 9 + 16 = 25. Yes, because it shows that you can rearrange the squares on the shorter sides to fill up the area of the square on the larger side. No, because a proof needs to have equations in order to be valid. No, because this proof only works when you can draw grids on the squares. It does not work for all right triangles.

128= 4^2x times 2^x
What is x?
Answers
Answer:
x=7/5
Step-by-step explanation:
We can write it in exponential form
128= 2^2*2x * 2^x
2^4x+x=5x
2^5x=128
2^5x=2^7
5x=7
x=7/5
The value of x in the equation given is
[tex] \frac{7}{5} [/tex]
To solve :
[tex]128 = {4}^{2x} \times {2}^{x} [/tex]
Change all values to have the same root :
[tex] {2}^{7} = {2}^{2(2x)} \times {2}^{x} [/tex]
[tex] {2}^{7} = {2}^{4x} \times {2}^{x} [/tex]
[tex] {2}^{7} = {2}^{(4x + x)} [/tex]
[tex] {2}^{7} = {2}^{5x} [/tex]
The roots cancel out
[tex] 7 = 5x[/tex]
Divide both sides by 5
[tex]x = \frac{7}{5} [/tex]
Therefore, the value of
[tex]x = \frac{7}{5} [/tex]

Answers
Answer:
A= 4
B= 4
C= -1
D= 4
E= -1
F= 4
G= -1
Step-by-step explanation:
The expected value equation is the probability of something happening multiplied by the amount of times it happens. In this case you have four equal sized sections, so you have a one in four chance to land in any of these sections. A, B, D, and F represent the four for this one in four chance. C, E, and G represent the amount of points you get when you land on those sections, in this case -1

An equation shows the equality of two variables while an inequality shows the inequality of two variables.
Answer: Equations and inequalities are both mathematical sentences formed by relating two expressions to each other. In an equation, the two expressions are deemed equal which is shown by the symbol =. Where as in an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.

A farmer wants to fence an area of 6 million square feet in a rectangular field and then divide it in half with a fence parallel to one of the sides of the rectangle. Let y represent the length (in feet) of a side perpendicular to the dividing fence, and let x represent the length (in feet) of a side parallel to the dividing fence. Let F represent the length of fencing in feet. Write an equation that represents F in terms of the variable x.
Answers
If the rectangular field has notional sides X and y then it has area
A(x) =xy { =6•10^6 sq ft }
The length of fencing required, if
x
is the letter that was arbitrarily assigned to the side to which the dividing fence runs parallel, is:l (x) = 3x +2y
It matters not that the farmer wishes to divide the area into 2 exact smaller areas.
Assuming the cost of the fencing is proportional to the length of fencing required, then
C(x)=a L (x)
To optimise cost, using the Lagrange Multiplier
λ
, with the area constraint :
So the farmer minimises the cost by fencing-off in the ratio 2:3, either-way
The relationship between variable F and x is 2x + 12000000/x
Let y represent the length (in feet) of a side perpendicular to the dividing fence, and let x represent the length (in feet) of a side parallel to the dividing fence.
Let F represent the length of fencing in feet.
Area of fencing = 6000000 ft²
Area of fencing = x * (y + y) = x * 2y
Area of fencing = 2xy
6000000=2xy
xy = 3000000
y = 3000000/x
The perimeter is:
F = x + y + y + x + y + y
F = 2x + 4y
F = 2x + 4(3000000/x)
F = 2x + 12000000/x
Therefore the relationship between variable F and x is 2x + 12000000/x

After the paint dries, Jackson cuts the cube in half. He makes the cut along the diagonal of one pair of
parallel faces. Rounded to the nearest thousandth, the diagonal has a length of 7.071 centimeters. Once
the cut is made, Jackson has two identical triangular prisms.
What is the combined area, in square centimeters, of the surfaces of the two prisms that were not painted?

70.71 cm²Step-by-step explanation:
There are two faces that are not painted.
They are rectangles with one side 5 cm, and another side 7.071 cm.
