A sale price for the bicycles that would allow this company to achieve a profit of $189,800 is: B. $230.
How to determine the sale price for the bicycles?In order to determine the sale price for the bicycles that would make it possible for this company to achieve a profit of $189,800, we would simply evaluate the profit function by substituting the value of the profit as follows:
P(x) = −2x² + 920x + 84,000
189,800 = −2x² + 920x + 84,000
Re-arranging the profit function by collecting like terms, we have:
2x² + 920x + 189,800 - 84, 000 = 0
2x² - 920x + 105,800 = 0
Dividing both sides by 2, we have:
x² - 460x + 52,900 = 0
Next, we would solve the quadratic equation by using factorization method:
x² - 230x -230x + 52,900 = 0
x(x - 230) + 230(x - 230) = 0
(x - 230)(x + 230) = 0
x = 230 or -230
Since the price cannot be negative, the required sale price for this company is equal to $230.

At the start of a trip, a car's gas tank contains 12 gallons of gasoline. During the trip, the car consumes 10 gallons of gasoline. How much gasoline is left in the tank? Should you represent this amount with a positive or negative value? Why?
If the tank contains 12 gallons and then the car consumes 10, we can know how much gasoline is left by substracting 12 with 10:
12 - 10 = 2
Then, 2 gallons of gasoline is left in the tank
Since there is still gasoline because 12 is higher than 10, then we represent this amount with a positive value.

Show that ABCD is a kite. Give a reason for each stage of your working
(The diagram is attached)
Thanks, by neve124
It is to be noted that by the proof given below, the attached shape ABCD is a kite.
What is a kite in Euclidean Geometry?A kite is a quadrilateral having reflection symmetry across a diagonal in Euclidean geometry. A kite has two equivalent angles and two pairs of adjacent equal-length sides as a result of its symmetry.
The proof is as follows:
AB = AD [Given]
∠ADC = 115° [Angles on a Straight line]
That is 180 - 65 = 115°
∠BCD = 20° [Vertical Angles are equal]
∠ABC = (360 - (20+115+110))
= 115° [Angles in a quadrilateral]
Hence,
ABCD = Kite [Definition of a Geometric Kit]
That is
It two equivalent angles (∠ABC and ∠ADC)It also has two pairs of adjacent equal-length sides (that is |AD| ≈ |AB|.QED

For Problems 3–6, find the opposite of the number.4.5
ANSWER
-4.5
EXPLANATION
We want to find the opposite of the number 4.5
The opposite of a number is the number that is the same distance from 0 on the number line but on the other side.
So, if the number is on the right hand side, its opposite is on the left hand side.
In simpler terms, the opposite of a number is the negative of a number.
So, the opposite of 4.5 is -4.5.
A salesperson works 40 hours per week at a job where he has two options for being paid option a is an early wage of $19 option B is a commission rate of 8% sales how much does he need to sell in a given week to earn the same amount with each option
The salesperson needs to make weekly sales of $9,500 to earn the same amount with each option.
The amount he earns by option A can be calculated as follows;
As he works 40 hours per week and the hourly wage is $19; therefore the amount he will earn can be determined by multiplication as follows;
Option A earning: 40 × 19 = $760
Thus, the salesperson earns $760 through option A.
Consider x to be the amount of weekly sales;
As the commission rate is 8% of sales therefore 8% of x should be equal to $760 for the salesman to earn the same amount with both options.
(8/100)x = 760
0.08x = 760
x = 760 / 0.08
x = 9,500
Hence the salesman needs to make weekly sales of $9,500 to earn the same amount with both options.
Although there is a mistake in your question, you might be referring to this question;

You have 8 times as many dimes as nickels. You have 18 dimes and nickels altogether how much money do you have in all?
For the given condition of dimes is 8 times of nickel and there are 18 dimes and nickels altogether, then total money is equal to $1.
As given in the question,
Let x be the number of dimes
Then number of nickels are 8x.
As per given condition,
Total number of dimes and nickels = 18
⇒ x + 8x = 18
⇒ 9x = 18
⇒ x= 2
Number of dimes =2
Number of nickels = 8(2)
= 16
Conversion:
1 dime = 0.10$
1 nickel = 0.05$
Total amount of money in dollars
= 2 ×(0.10) + 16× (0.05)
= 0.20 + 0.80
= 1.00
Therefore, for the given condition of dimes is 8 times of nickel and there are 18 dimes and nickels altogether, then total money is equal to $1.

The equation of the line that is perpendicular to the line 5x + 6y = 18 and passes through the point (10,7)
Answer:
y = ( 6 / 5 )x - 5;
Step-by-step explanation:
Perpendicular Line Theoryy = - ( 1 / m )x + c;
AlgebraConvert dual intercept to standard form.
5x + 6y = 18;
Subtract 5x from both sides.
6y = - 5x + 18;
Divide both sides by 6.
y = ( - 5x + 18 ) / 6;
y = ( - 5x / 6 ) + ( 18 / 6 );
y = ( - 5 / 6 )x + 3;
Get the perpendicular line.
y = ( 6 / 5 )x + c;
Substitute the point.
7 = ( 6 / 5 )( 10 ) + c;
7 = 12 + c;
Subtract 12 from both sides.
- 5 = c;
c = - 5;
y = ( 6 / 5 )x - 5;
Data were collected on the distance a baseball will travel when hit by a baseball bat at a certain speed. The speed, s, is measured in miles per hour, and distance, y, is measured in yards. The line of fit is given by ŷ = 3.98 + 53.59s. If the ball travels for a duration of 5 seconds, what is the predicted distance of the ball?
The predicted distance of the ball would be 27.1.93 yards when the ball travels for a duration of 5 seconds.
What is the velocity?Velocity is defined as the displacement of the object in a given amount of time and is referred to as velocity.
The distance, y, is measured in yards and the speed, s, is measured in miles per hour.
The regression line is defined as ŷ = 3.98 + 53.59s ... (i)
The slope and y-intercept of the regression line must be determined.
The general equation for a linear regression line is y = a + bx...(ii), where x is a variable. The variable is indicated by s in the above equation.
When I and (ii) are compared, we obtain a = 3.98 and b = 53.59.
It indicates that the slope is 53.59 and the y-intercept is 3.98.
The slope, b = 53.59, implies that for every mile per hour of speed, the distance rises by 53.59 yards.
The ball travels for a duration of 5 seconds
Substitute the value of s = 5 in equation (i) to get
ŷ = 3.98 + 53.59(5)
ŷ = 271.93
Thus, the predicted distance of the ball would be 27.1.93 yards.

A box has a width of 12 cm and a length of 9 cm. the volume of the box is decreasing at a rate of 541 cubic cm per second, with the width and length being held constant. what is the rate of change of the height, in cm per second, when the height is 6 cm?
With the width and length being held constant, the height of the box decreases at rate 5 cm/s
Let:
l = length
w = wide
h = height
Then, the volume of the box is given by:
V = l . w. h
The length and the width are assumed to be constant. Hence, the derivative with respect to time is:
dV/dt = l . w dh/dt
Parameters given:
dV/dt = - 541 cm³/dt

Write an equation of a parabola with a vertex at the origin and a directrix at y=5
SOLUTION
The equation of the parabola is defined using
[tex]y=\frac{1}{4(f-k)}(x-h)^2+k[/tex]Since the vertex is at the origin the equation becomes
[tex]\begin{gathered} y=\frac{1}{4(f-0)}(x-0)^2+0 \\ y=\frac{1}{4f}x^2 \end{gathered}[/tex]Since the directrix is y=5
The distance from the focus to the vertex is equal to the distance from the vertex to the directrix
It follows
[tex]\begin{gathered} f-k=k-5 \\ f=-5 \end{gathered}[/tex]Thus the equation becomes

The approximate range of the current is 299.5.
How to estimate the approximate range of the current?The current is defined as rate of flow of charge I = dq/dt
Let the equation be [tex]$q=\int i d t$[/tex]

We will substitute it in the above equation
q = [tex]$$\int[/tex] 10 cos(120πt - 12π) + 5 dt
now here limits of time is from t = 0.1 to t = 60 s
so here it will be given as
