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.

On a long-distance biking trip, annike started biking at 7 a.M., and her average speed was 11 miles per hour. Celia started at 8 a.M., and her average speed was 14 miles per hour
Answer:
3.67 hours
Step-by-step explanation:
Speed is the ratio of distance to time, it is given by the formula:
Speed = Distance / time
For annike her average speed was 11 miles per hour and she started at 7 am.
At 8 am (time = 1 hr i.e 7 am to 8 am) the distance she would have covered is given as:
11 miles/hr = distance / 1 hr
Distance = 11 miles per hr × 1 hr = 11 miles
After 8 am, the distance traveled at time t is:
11 = distance/t
distance = 11t
Total distance = 11t + 11
For Celia she started at 8 am at 14 miles per hour, at time t, the distance traveled is:
14 = distance/t
Distance = 14t
Given that both bikers traveled the same distance, hence:
14t = 11t + 11
3t = 11
t = 11/3
t = 3.67 hours

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 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.

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].

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.
Ben's favorite deli says the average serving time is 12 minutes. Ben notices that the wait time at the deli varies at different times of day, before and after noon. His observations when the wait time is as advertised can be represented by the equation 2|x − 2| − 12 = 0. Solve for the times when the serving time is as advertised, relative to noon.
Answer:
Step-by-step explanation:
Given Ben's observations when the wait time is as advertised represented by the equation 2|x − 2| − 12 = 0, to get the times when the serving time is as advertised, relative to noon, we will calculate for the value of x in the equation;
Note that the modulus of the function |x-2| will return both positive and negative value.
For the positive value of |x-2|;
2|x − 2| − 12 = 0
2(x − 2) − 12 = 0
open the parenthesis
2x-4 - 12 = 0
2x - 16 = 0
add 16 to both sides
2x-16+16 = 0+16
2x = 16
x = 16/2
x = 8
For the negative value of |x-2|;
2|x − 2| − 12 = 0
-2(x − 2) − 12 = 0
open the parenthesis
-2x+4 - 12 = 0
-2x - 8 = 0
add 8 to both sides
-2x-8+8 = 0+8
-2x = 8
x = -8/2
x = -4
Hence the times when the serving time is as advertised, relative to noon are 8minutes and 4minutes

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.
