Woodland Bicycles makes two models of off-road bicycles: the Explorer, which sells for $250, and the Grande Expedition, which sells for $350. Both models use the same frame, but the painting and assembly time required for the Explorer is 2 hours, while the time is 3 hours for the Grande Expedition. There are 375 frames and 450 hours of labor available for production. How many of each model should be produced to maximize revenue?
Answers
To maximize revenue, we need to determine the number of each model of off-road bicycles that should be produced based on the given constraints. The revenue generated from selling each model is multiplied by the number of units sold. We set up a system of equations to represent the constraints and objective function, and then use graphical methods or linear programming algorithms to find the optimal solution.
Explanation:To maximize revenue, we need to determine the number of each model of off-road bicycles that should be produced. Let's assume x represents the number of Explorer bicycles and y represents the number of Grande Expedition bicycles.
The revenue generated from selling the Explorer bicycles is 250x, while the revenue from selling the Grande Expedition bicycles is 350y.
We are given that the painting and assembly time required for the Explorer is 2 hours, so the total time used for producing the Explorer bicycles is 2x hours. Similarly, the total time used for producing the Grande Expedition bicycles is 3y hours.
We also know that there are 375 frames and 450 hours of labor available. Each bicycle requires one frame and a certain number of labor hours, so the total number of frames used is x + y, and the total labor hours used is 2x + 3y.
We can set up the following system of equations to represent the constraints:
x + y ≤ 375 (due to the limited number of frames)
2x + 3y ≤ 450 (due to the limited number of labor hours)
To maximize revenue, we need to maximize the objective function R = 250x + 350y. Since we are dealing with a linear programming problem, we can use graphical methods or linear programming algorithms to find the optimal solution.

A. $4,373.68
B. $2,725.67
C. $4,358.69
D. $1,722.25
Answers
Your formula is r = n(ln(A/P)/(nt)) R being the interest rate of what your trying to find. So A= 3,634.51 P = 2,564.65 N is the number of times compounded per year.N= 2 and t is the number of years t= 13. Also while doing so use PEMDAS Let me know if you need any more help!
Compound interest formula is :
[tex]A=p(1+\frac{r}{n} )^{nt}[/tex]
1.
A = 3634.51
p = 2564.65
r = ?
n = 2
t = 13
Putting the values in formula, we get
[tex]3634.51=2564.65(1+\frac{r}{2} )^{2*13}[/tex]
=> [tex]3634.51=2564.65(1+\frac{r}{2} )^{26}[/tex]
=> [tex]\frac{3634.51}{2564.65}=(\frac{2+r}{2} )^{26}[/tex]
=> [tex]1.417=(\frac{2+r}{2} )^{26}[/tex]
We get [tex]\sqrt[26]{1.417}=\frac{2+r}{2}[/tex]
We get r = 0.02699 and r = -4.02699 (neglecting the negative value)
We get r = 0.027 (rounded)
And in percentage, it is 2.7%.
So, option C is the answer.
2.
p = 2651.43
r = 2.8% or 0.028
n = 2
t = 18
Putting the values in formula we get;
[tex]A=2651.43(1+\frac{0.028}{2} )^{2*18}[/tex]
=> [tex]A=2651.43(1.014)^{36}[/tex]
A = $4373.67
So, interest earned = [tex]4373.67-2651.43=1722.24[/tex] dollars
Hence, option D. $1,722.25 is the answer.
For which to pairs of function is (f•g) (x) =x
Answers
if f(x) = 2/x and g(x) = 2/x
f(g(x)) = [2 /(2/x)]
f(g(x)) = [2 * x/2 ]
f(g(x)) = x .............matching the function
answer is
B. f(x) = 2/x and g(x) = 2/x
Answer:
[tex]f(x)=\frac{2}{x}[/tex] and [tex]g(x)=\frac{2}{x}[/tex]
Step-by-step explanation:
To prove that we have to demonstrate [tex](f*g)(x)=x[/tex]
This proof is about a composition of functions, where we have to enter one function inside another, in this case, [tex]g(x)[/tex] goes inside [tex]f(x)[/tex]. So if results in [tex]x[/tex], then will be proved.
[tex](f*g)(x) = \frac{2}{\frac{2}{x} }[/tex]
As you can see, the composition is to replace [tex]g(x)[/tex] for the variable of [tex]f(x)[/tex].
Solving the expression:
[tex](f*g)(x) = \frac{2}{\frac{2}{x} }=\frac{2x}{2}=x[/tex]
After replacing and applying the composition, we have [tex]x[/tex] as a result. Therefore, we can say that the pair of functions of option B is the answer, because they satisfy the expression given.
Find the critical numbers of the function f(x) = x6(x − 1)5 what does the first derivative test tell you that the second derivative test does not?
Answers
The first derivative is
f'(x) = 6x⁵(x-1)⁵ + 5x⁶(x-1)⁴
= x⁵(x-1)⁴(6x - 6 + 5x)
= x⁵(x-1)⁴(11x - 6)
The critical values are the zeros of f'(x). They are
x = 0, 6/11, and 1.
The critical values indicate that turning points exist for f(x) at the critical points. However, we do not know the nature of the turning points.
Write the first derivative in the form f'(x) = (x-1)⁴(11x⁶ - 6x⁵).
The second derivative is
f''(x) = 4(x-1)³(11x⁶ - 6x⁵) + (x-1)⁴(66x⁵ - 30x⁴)
= (x-1)³(44x⁶ - 24x⁵ + 66x⁶ - 30x⁵ - 66x⁵ + 30x⁴)
= (x-1)³(110x⁶ - 120x⁵ + 30x⁴)
= 10x⁴(x-1)³(11x² - 12x + 3)
The sign of f''(x) at the critical values tell us the nature of the turning point.
f''(0) = 0, therefore a point of inflection exists at x = 0.
f''(6/11) > 0, therefore a local minumum exists at x = 6/11.
f''(1) = 0, therefore a point of inflection exists at x=1.
The graphs shown below confirm these results.
The critical numbers of [tex]\( f(x) = x^6 (x-1)^5 \)[/tex] are [tex]\( x = 0, 1, \frac{5}{6} \)[/tex]. The first derivative test determines maxima/minima by sign change, while the second derivative test confirms concavity but not explicit categorization.
1. Calculate the first derivative [tex]\( f'(x) \)[/tex]:
Use the product rule and simplify:
[tex]\[ f(x) = x^6 (x-1)^5 \] \[ f'(x) = 6x^5 (x-1)^5 + x^6 \cdot 5(x-1)^4 \] \[ f'(x) = 6x^5 (x-1)^4 [x + 5(x-1)] \] \[ f'(x) = 6x^5 (x-1)^4 (6x - 5) \][/tex]
2. Find critical points:
Critical points occur where [tex]\( f'(x) = 0 \)[/tex] or is undefined.
Set [tex]\( f'(x) = 0 \)[/tex]:
[tex]\[ 6x^5 (x-1)^4 (6x - 5) = 0 \][/tex]
This equation is zero when:
[tex]\( 6x^5 = 0 \) -- \( x = 0 \)\\ \( (x-1)^4 = 0 \) -- \( x = 1 \)\\ \( 6x - 5 = 0 \) -- \( x = \frac{5}{6} \)[/tex]
So, the critical numbers are [tex]\( x = 0, 1, \frac{5}{6} \)[/tex].
3. First Derivative Test vs. Second Derivative Test:
- First Derivative Test: This test uses the sign of the derivative ( f'(x) ) to determine the nature of critical points:
- If [tex]\( f'(x) > 0 \) to \( f'(x) < 0 \)[/tex] at x, then ( f(x) ) has a local maximum at x.
- If [tex]\( f'(x) < 0 \) to \( f'(x) > 0 \)[/tex] at x, then ( f(x) ) has a local minimum at x.
- Second Derivative Test: This test uses the sign of the second derivative [tex]\( f''(x) \)[/tex]:
- If [tex]\( f''(x) > 0 \), \( f(x) \)[/tex] has a local minimum at x.
- If [tex]\( f''(x) < 0 \), \( f(x) \)[/tex] has a local maximum at x.
4. Difference between the tests:
- The first derivative test provides information about the nature (whether maximum or minimum) of critical points based on the sign change of the derivative.
- The second derivative test provides more precise information by confirming the concavity of the function around the critical point, but it does not give explicit information about whether the critical point is a maximum or minimum (it only confirms the direction of concavity).
If ABC and DEF are supplementary, then ABC and DEF form a linear pair
Answers
The statement is true. If two angles are supplementary meaning their sum is 180 degrees, they form a linear pair because in a linear pair too, the sum of the two angles is 180 degrees.
Explanation:The question is related to the concept of angles in geometry. When angles are supplementary, it means that the sum of the two angles is 180 degrees. In a linear pair, two adjacent angles form a straight line, which also sums up to 180 degrees.
So, if angles ABC and DEF are supplementary, meaning ABC + DEF = 180 degrees, they indeed form a linear pair. Because in a linear pair too, the sum of the two angles is 180 degrees. Therefore, the statement 'If ABC and DEF are supplementary, then ABC and DEF form a linear pair' is true.

The lines are parallel if and only if the values of their slopes are equal. In a standard form of the equation of the line, the slope is the numerical coefficient of x. Given this condition, we determine the value of a by equation a + 12 and 4a.

Answer:
The equation of the line would be y = 6x + 2
Step-by-step explanation:
Since we have a slope (6) and a point (0,2) we can use them in point slope form. The slope goes in for m and the point goes in for (x1, y1).
y - y1 = m(x - x1)
y - 2 = 6(x - 0)
y - 2 = 6x
