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)

Rebecca earned $115 in simple interest for 8 months at an annual interest rate of 3%. How much money did she start with in her account?
The amount of money she started with is $5750
How to determine the amount she start with?The given parameters are:
Interest = $115
Rate = 3%
Time = 8 months
The amount she start with (P) is calculated using:
P = I/(RT/12)
This gives
P = 115/(3% * 8/12)
Evaluate the product
P = 115/(0.02)
Divide
P = 5750
Hence, the amount of money she started with is $5750

The area of rectangle is 2356 square meters. The length is 38 meters. What is the width?
Answer:
62 meters
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:
[tex]2356 m^2 = 38 m * w[/tex]
Divide both sides by 38 m
[tex]62 m = w[/tex]

pls help asap, find the height of the cylinder and round to the nearest tenth
Answer:
h = 2.4
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h where r is the radius and h is the height
271.4 = pi ( 6)^2 *h
271.4 = 36* pi* h
Letting 3.14 = pi
271.4 = 113.04 h
Divide each side by 113.04
271.4 /113.04 = 113.04h/113.04
2.424805379 = h
Rounding to the nearest tenth
2.4 = h
OR if we use the pi button
271.4 = 36 * pi *h
Divide each side by 36 pi
271.4/36pi = h
h=2.3997
Rounding to the nearest tenth

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°
What is the primary importance of benefits 1and 2 as discussed in "the pros and cons of patents"?
Benefits 1 and 2 in the 'Pros and Cons of Patents' significantly throws light on the opportunity of owning a market, and securing funds respectively.
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.
If an invention is not protected, no one will put their money at risk The only way an invention can ensure a return is through patent protection since investors don't care about good intentions; they only care about money.

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.

What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.Researching the problem on the internet, there was a base fee of $18.99, which is the y-intercept, and there was an additional charge of 75 cents for each mile driven, which is the slope, hence the cost function for m miles driven is given by:
C(m) = 18.99 + 0.75m.
He paid $199, hence the number of miles he drove is found as follows:
C(m) = 18.99 + 0.75m.
