Reflect shape A in the y-axis.
Answer:
(-1,1) (-4,1) (-4,3)
Step-by-step explanation:
literally mirror shape A to the y-axis
the original cordinates:
(1,1) (4,1) (4,3)
would now be
(-1,1) (-4,1) (-4,3) because it's reflected
Translate (5, 1) to the right 3 units.
Then reflect the result over the y-axis.
What are the coordinates of the final point?
Answer:
Step-by-step explanation:
Answer
When you translate either left or right, the x coordinate is the one that you change. To go right when you are dealing with a point, you must add the amount you are asked to go right. So when you go right 3 units, add 3 to the 5.
(5 + 3,1) = (8,1)
when going across the y axis, you are still only changing the x coordinate.
All you need do is put a minus sign in front of the x coordinate. So your final answer is (-8,1)

Two shops, Lidal and Oldi, sell the same brand of toilet rolls but with different package sizes.
Calculate the price per roll for each shop.
Write which shop is the best value for money in the comment box.
lidal:8 for 2.80
oldi:9 for 3.24
The price per roll for Lidal and Oldi shop is 0.35 and 0.36 respectively.
Therefore Lidal shop is the best value for money.
Given,
Lidal shop:
8 rolls costs 2.80
∴ one roll costs = 2.80/8
= 0.35
Oldi shop:
9 rolls costs 3.24
∴ one roll costs = 3.24/9
= 0.36
Hence we get the per price for the shops as 0.35 and 0.36
we can see that for lidal shop if per roll it is 0.35 then if a person wants to buy 9 rolls then it will cost him 3.15, whereas in the case of oldi shop the price for 9 rolls is 3.24.Therefore, lidal shop is the best value for money.

What is the primary importance of benefits 1 and 2?
Benefit 1 of 'Pros and Cons of Patents' is about the possibility of owning a market.
Since the US government will protect your creation for 20 years, you will essentially control the market for that product during that time. For instance, Eli Lilly invented Prozac in 1987 and had the monopoly for 14 years until 2001.
Benefit 2 of 'Pros and Cons of Patents' concerns around attracting and accumulating the sources of funding and investors.

Answer:
According to the article, patents allow inventors to “own the market” for their ideas, meaning the US government has deemed the idea original and protected the idea from being reproduced by others for 20 years. This makes the idea more marketable, which allows the inventor to attract investors. These benefits support the idea that patents promote invention.

100 POINTS!! Find the indicated angle or side. Give an exact answer.
Find the measure of angle A in degrees.
Answer:
A = 120
Step-by-step explanation:
To find angle A we will need to use the law of cosines, since we know the three sides of the triangle.
a^2=b^2+c^2−2*b*c*cosA
(2 sqrt(13)) ^2 = 6^2 + 2^2 + 2 * 6 * 2 cos A
4*13 = 36 + 4 - 24 cos A
52 = 40- 24 cos A
12 = -24 cos A
-1/2 = cos A
Take the inverse cos of each side
cos^-1(-1/2) = cos^-1(cos A)
120 = Cos A or 240 = Cos A
A cannot be greater than 180 so A = 120
Answer:
A = 120°
Step-by-step explanation:
We can use the cosine rule to solve for angle A, since lengths of all sides are known:
[tex]a^2 = b^2+ c^2 - 2(b)(c) \space\ cos A[/tex]
where a, b, and c are the sides opposites angles A, B, and C respectively.
∴ a = 2√3 , b = 6, c = 2
• Rearranging the formula to make A the subject:
[tex]2(b)(c) \space\ cos A = b^2 + c^2 -a^2[/tex]
⇒ [tex]cos A = \frac{b^2 + c^2 -a^2}{2(b)(c)}[/tex]
⇒ [tex]A = cos^{-1}(\frac{b^2 + c^2 -a^2}{2(b)(c)} )[/tex]
• Now we can substitute the values into the equation to calculate the value of angle A:
[tex]A = cos^{-1}(\frac{6^2 + 2^2 -(2\sqrt{13})^2}{2(6)(2)} )[/tex]
⇒ [tex]A = cos^{-1} (-\frac{1}{2} )[/tex]
⇒ A = 120°

Answer:

Step-by-step explanation:
So the area of a rectangle can be defined as: [tex]A = wl[/tex] where A=area, w=width, l=length. So if we plug in the known values we can solve for the unknown, which in this case is the width. So let's plug in the known values:

The Volume of the composite figure = Volume of the rectangular prism + Volume of the square pyramid = 4,050 ft³.
How to Find the Volume of a Composite Figure?The composite figure shown is composed of a square pyramid and a rectangular prism. To find the volume of the composite figure, find the volume of the square pyramid and the volume of the rectangular prims respectively.
Volume of the square pyramid = 1/3(B)(h), where:
Base area (B) = (l)(w) = (15)(15)
Base area (B) = (l)(w) = 225 ft³.
h = 9 ft
Volume of the square pyramid = 1/3(225)(9)
Volume of the square pyramid = 675 ft³.
Volume of the rectangular prism = (length)(width)(height)
Volume of the rectangular prism = (15)(15)(15)
Volume of the rectangular prism = 3,375 ft³.

Use the given degree of confidence and sample data to construct a confidence interval for the population proportion p. n = 195, x = 126; 95% confidence
Using the z-distribution, the 95% confidence interval for the population proportion is (0.5791, 0.7133).
What is a confidence interval of proportions?
A confidence interval of proportions is given by:
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which:
[tex]\pi[/tex] is the sample proportion.z is the critical value.n is the sample size.In this problem, we have a 95% confidence level, hence[tex]\alpha = 0.95[/tex], z is the value of Z that has a p-value of [tex]\frac{1+0.95}{2} = 0.975[/tex], so the critical value is z = 1.96.
The other parameters are given as follows:
[tex]n = 195, \overline{p} = \frac{126}{195} = 0.6462[/tex]
Hence the bounds of the interval are:
[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.6462 - 1.96\sqrt{\frac{0.6462(0.3538)}{195}} = 0.5791[/tex]
[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.6462 + 1.96\sqrt{\frac{0.6462(0.3538)}{195}} = 0.7133[/tex]
