Answer:
(2n / n^2 + 7) - 3 i think
Step-by-step explanation:
hope this helped a little bit :))
The mathematical expression will be (2n / n² + 7) - 3.
What is an expression?The mathematical expression is the combination of numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also be used to denote the logical syntax's operation order and other properties.
Given that the quantity three is less than twice this number divided by the quantity 7 more than the square of this number.
The required expression will be written as:-
E= (2n / n² + 7) - 3.
Therefore, the mathematical expression will be (2n / n² + 7) - 3.

A regulation baseball field measures 90 feet between each base.What is the distance around the bases in meters?
Answer:
360 ft
Step-by-step explanation:
to find the total distance between the bases, you would multiply 90 by 4!
if it helps, since there are 4 bases, each of them being the same distance apart, they would make a square. each side of the square would be 90 ft. then find the perimeter! 90×4=360!

Simplify each expression using an exponent rule learned in class. [tex](\frac{y}{x} )^{4}[/tex]
Hey there! I'm happy to help!
If you raise a fraction to an exponent, you apply that exponent to the numerator and the denominator. This would give us [tex]\frac{y^4}{x^4}[/tex].
Have a wonderful day! :D
Since the exponent is outside the fraction, you apply the exponent to both the numerator and denominator.
(y/x)^4 = y^4/x^4

If [tex]f(x)=x^2-2[/tex] and [tex]g(x)=3x[/tex], what is [tex](f\circ g)(2)[/tex]?
Answer:
[tex]\boxed{f(6) = 34}[/tex]
Step-by-step explanation:
Composition of functions occurs when we have two functions normally written similar or exactly like f(x) & g(x) - you can have any coefficients to the (x), but the most commonly seen are f(x) and g(x). They are written as either f(g(x)) or (f o g)(x). Because our composition is written as [tex](f \circ g)(2)[/tex], we are replacing the x values in the g(x) function with 2 and simplifying the expression.
[tex]g(2) = 3(2)[/tex]
[tex]g(2) = 6[/tex]
Now, because we are composing the functions, this value we have solved for now replaces the x-values in the f(x) function. So, f(x) becomes f(6), and we use the same manner as above to simplify.
[tex]f(6) = (6)^2-2[/tex]
[tex]f(6) = 36-2[/tex]
[tex]f(6) = 34[/tex]
Therefore, when we compose the functions, our final answer is [tex]\bold{f(6) = 34}[/tex].
Answer:
[tex]\large\boxed{34}[/tex]
Step-by-step explanation:
[tex]f(x) = x^2 - 2[/tex]
[tex]g(x) = 3x[/tex]
[tex](fog)(2)[/tex]
Find g(2)
[tex]g(x) = g(2)[/tex]
[tex]x=2[/tex]
[tex]3x = 3(2) = 6[/tex]
[tex]g(2) = 6[/tex]
Find f(6)
[tex]f(x) = x^2-2[/tex]
Substitute
[tex]f(6) = x^2 - 2[/tex]
[tex]x^2 - 2 = 6^2 - 2[/tex]

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.
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.

Solve the triangle if C = 120°, B = 50°, and c = 15.
Find A.
Round to the nearest tenth.
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.

Leah scored 35 points in a basketball game and she scored x points in the
first half of the game. Write an expression to determine the number of
points she scored in the second half of the game. Then, find the number
of points she scored in the first half of the game if she scored 17 points in
the second half of the game.
x = # of points scored in the first half of the game
35 - x <---- This expression tells us how many points Leah scored in the second half of the game.
Leah scored 17 points in the second half of the game, let's set our expression equal to 17
35 - x = 17
Subtract 35 from both sides
-x = -18
Divide both sides by -1
x = 18
Leah scored 18 points in the first half of the game.
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
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.
