2n/n^2
I got n/n^2 .
Answers
Answer:
[tex]\frac{2}{n}[/tex]
Step-by-step explanation:
[tex]\frac{2n}{n^2}[/tex] (exponential rule for fraction is the number subtract each other)
[tex]2n^{-1}[/tex] (from the top n exponent of 1 minus bottom exponent of2 (1-2=-1))
since the n is a -1 exponent to make it positive you put it in the denominator
[tex]\frac{2}{n}[/tex]
(the reason it's not n/n^2 is that the two cannot just disappear or be taken away unless you are solving for something and the n/n^2 can also be simplified into the 1/n)

Solve the triangle if C = 120°, B = 50°, and c = 15.
Find A.
Round to the nearest tenth.
Answers
Answer:
A = 10°a = 3.0b = 13.3Step-by-step explanation:
The law of sines is useful. First we need to find the remaining angle.
A + B + C = 180°
A = 180° - B - C = 180° -50° -120°
A = 10°
Now we can find the other two sides.
a/sin(A) = c/sin(C)
a = c(sin(A)/sin(C)) = 15(sin(10°)/sin(120°)) ≈ 3.00767 ≈ 3.0
b/sin(B) = c/sin(C)
b = c(sin(B)/sin(C)) = 15(sin(50°)/sin(120)) ≈ 13.2683 ≈ 13.3
___
The solution is A = 10°, a = 3.0, b = 13.3.
A train is moving at a rate of 65 miles/hour toward a railroad marker located 200 miles away. Which equation could be used to find the time it will take for the distance between the train and the railroad marker to be 4 miles apart, where h represents the time in hours? A. |4 + 65h| = 200 B. |200 − 65h| = 4 C. |65 − 4h| = 200 D. |200 − 4h| = 65
Answers
Answer:
|200-65h|=4
Step-by-step explanation:
The required equation to find the time it will take for the distance between the train and the railroad marker to be 4 miles apart, where h represents the time in hours is | 200 - 65h | = 4. Option B is correct.
Given that,
A train is moving at a rate of 65 miles/hour toward a railroad marker located 200 miles away.
Distance is defined as the object traveling at a particular speed in time from one point to another.
Let the time be h and the distance traveled by train in time h is 65h.
Since at time h the distance between the train and rail road maker is 4 miles,
So the expression can be given as train traveled 65h distance to reduce the distance of 200 miles to 4 miles
| 200 - 65h | = 4
MODULUS is used because distance can never be negative.
Thus, the required equation to find the time it will take for the distance between the train and the railroad marker to be 4 miles apart, where h represents the time in hours is | 200 - 65h | = 4.

Soccer balls go on sale for $7.50 each. The store also sells footballs and the manager wants to earn a daily profit of $400 from both items. The equation y=-4x^2+80x-150 models the store’s daily profit, y, for selling footballs at x dollars. Explain how to find the price per football needed to meet the goal.
Answers
Answer:
The price for footballs is $5.46 and $14.54.
Step-by-step explanation:
Using the information that we have about the soccer ball prices, we can find out their daily profit to see how much the footballs daily profit should be. Plugging in 7.50 into the equation, we get 232.5 as their daily profit. To find what the footballs daily profit should be, we must minus 232.5 from 400. This ends up with 167.5
Now to find the price of the footballs, we must plug 167.5 into the equation and use the quadratic formula to find the prices.
Hope this helps : )
Answer:
At $7.50 per soccer ball, they earn a daily profit of $232.50.
The store needs to earn a daily profit of $400 – $232.50 = $167.50 from footballs.
Solve 167.50 = –4x2 + 80x – 150 to find the price for footballs: x = $5.46 and $14.54.

Considering that the lower intersection is a translation of the upper intersection what does this mean about the measures of the corresponding angles
Answers
This mean about the measures of the corresponding angles the lower intersection is a translation of the upper intersection. This means that corresponding angles overlap each other on translation. So, the corresponding angles are congruent This is further explained below.
What is angles?Generally, angles is simply defined as the angle formed when two lines or surfaces meet, or the distance between them (typically measured in degrees).
In conclusion, What does this imply about the sizes of the associated angles Simply said, the bottom intersection is a literal translation of the higher one. What this indicates is that, when translated, the relevant angles overlap. As a result, the two angles are equal.
