a) show how pip can complete the circuit by adding less than 120cm of track
b) show how pip can complete the circuit by adding more than 270cm of track
c) explain why, no matter how the circuit is completed, pip must place an even number of additional curved plates
d) explain why, no matter how the circuit is completed, pip must place an odd number of additional straight plates
In order to complete the circuit, the curved plate on the topmost right side of the circuit must be moved downwards to the end. The length of the total plates to be added is 100cm. Refer to the use of polygons.
How did we arrive at 100cm above?Step 1
In order to complete the circuit, the curved plate on the topmost right side of the circuit must be moved downwards to the end. This is already existing on the circuit so it is not part of the plate to be added.
Step 2
Using the plate with the straight line, the other spaces which are 5 in number will be completed. The total length of plates used will amount to 100cm.
Because the plate is equal in length and height, the total number of plates used is:
20 * 4 = 100cm.

Please help!!!you must use the desmos caculator
Part (a)
Open up Desmos and click on the button that looks like a plus sign. It's at the upper left corner. We're going to want to add a table.
Type all of the values into the table. This table is stacked vertically compared to yours which is laid out horizontally. It's the same thing pretty much. It depends on your preference on which you like better.
After the data values are typed in (which is a bit of a tedious process if you ask me), you'll then move to the next input box to type the following
[tex]y_1 \sim mx_1 + b[/tex]
Type it in exactly as you see it. To get the small '1's as subscripts, you'll need to use an underscore. So you'll type y_1 to mean [tex]y_1[/tex]
The ~ symbol is likely found in the upper left portion of your keyboard.
After typing that into the second input box, you should get what you see in the screenshot below.
The parameters your teacher wants are the m and b values.
Desmos is showing these values:
m = 0.125873b = -7.11916These values are approximate. As the instructions state, do not round the values mentioned.
Therefore, we go from y = mx+b to y = 0.125873x-7.11916 approximately
This is the regression line. It is the closest line to all of the points.
Answer: y = 0.125873x-7.11916===========================================================
Part (b)
The year 2022 is 2022-1900 = 122 years after the year 1900.
This means we'll plug x = 122 into the regression equation to find the predicted value for y.
y = 0.125873x-7.11916
y = 0.125873*122-7.11916
y = 8.237346
I used the Desmos input box as a calculator. Simply type in 0.125873*122-7.11916 exactly as you see it and it should produce the value 8.237346
That then rounds to 8.24
We predict in the year 2022, the minimum wage should be about $8.24
This is an estimated value because the regression line isn't perfect. In fact, the further we move away from the main known points, the worse off the estimation will likely get. This is why extrapolation could be a bad idea. However, it's a fairly good way to see what's going on.

(2) P(A) = 0.8, P(B) = 0.25
(3) P(A/B) = 0.2, P(B) = 0.2
(4) P(A) = 0.15, P(B) = 0.05
Answer: answer choice 2) P(A) = 0.8, P(B) = 0.25
Step-by-step explanation:
The True statement is P(A) = 0.8, P(B) = 0.25.
The correct option is (B).
What is Conditional Probability?Conditional probability is a measure of the probability of an event occurring, given that another event has already occurred.
1. 0.4 ·0.3≠ 0.2,
2. 0.8 · 0.25 = 0.2
3. P(A|B)= P(A)= 0.2
0.2 ≠ 0.2 · 0.2
4. 0.2 ≠ 0.15 · 0.05
Hence. the only condition is satisfied is (B).

In the figure below, the segments WX and W Y are tangent to the circle centered at 0. Given that OX= 4 and OW = 8.5, find WY.
Answer:
7.5
Step-by-step explanation:
because OY is a radius like OX they will have equal length of 4 so OY = 4
Because of the circle theorem that says that tangents meet the the radius of a circle at 90 degrees, angle OYW is 90 degrees so the triangle OYW is a right angle triangle and we can use pythagoras theorem to get WY as:
[tex]8.5^{2} - 4^{2} = WY^{2} \\\sqrt{WY^{2}}=WY=7.5[/tex]
x^2+y^2−4x+2y=b
The radius of the circle is 7 units. What is the value of b in the equation?
Answer:
b = 44
Step-by-step explanation:
We can complete the square(s) to put the equation in standard form. Then we can find the value of b that makes the radius be 7 units.
__
x^2 +y^2 -4x +2y = b . . . . . given
(x^2 -4x) +(y^2 +2y) = b . . . . group by variable
(x^2 -4x +4) +(y^2 +2y +1) = b + 4 + 1 . . . . complete the squares
(x -2)^2 +(y +1)^2 = b +5 = 7^2 = 49 . . . . . write as squares, show radius

What is trigonometry?The connection between the lengths and angles of a triangular shape is the subject of trigonometry.
In triangle ABC, the side AB is 9 in, the side BC is 27 in, and the angle B is 97 degrees.
Then the other two angles and the side CA will be
The side CA is given by the cosine rule. Then we have
[tex]\rm CA^2 = AB ^2+ BC^2 - 2 \times AB \times BC \cos B\\\\\\CA^2 = 9^2 + 27^2 - 2 \times 9 \times 27 \cos 97^o\\\\\\CA^2 = 810 + 59.23\\\\\\CA ^2 = 869.23\\\\\\CA \ = 29.48 \ in[/tex]
Then angle A will be given by the sine rule. Then we have
[tex]\dfrac{27}{\sin A} = \dfrac{29.48}{\sin 97^0}\\\\\\\sin A = \dfrac{27 \sin 97^0}{29.48}\\\\\\\sin A = 0.9090\\\\\\A \ \ \ \ = 65.37^0[/tex]
Then the angle C will be
∠A + ∠B + ∠C = 180°
65.37° + 97° + ∠C = 180°
∠C = 17.63°
