A company sells widgets. The amount of profit, y, made by the company, is related to
the selling price of each widget, x, by the given equation. Using this equation, find out
what price the widgets should be sold for, to the nearest cent, for the company to
make the maximum profit.
y = -x2 + 72x – 458
Answer:
In order to make the maximum profit, the company should sell each widget at (the currency isn't given, so I'll be assuming USD) $36.
Step-by-step explanation:
The amount of profit y made by the company from selling each widget at x price is modeled by the equation:
[tex]y=-x^2+72x-458[/tex]
Since this is a quadratic with a negative leading coefficient, its maximum will occur at its vertex point. We want to find the price that the widget should be sold to make the maximum profit. So, we want to find the x-coordinate of the vertex. This is given by the formula:
[tex]\displaystyle x=-\frac{b}{2a}[/tex]
In this case, a = -1, b = 72, and c = -458. Substitute and evaluate:
[tex]\displaystyle x=-\frac{72}{2(-1)}=36[/tex]
In order to make the maximum profit, the company should sell each widget at (the currency isn't given, so I'll be assuming USD) $36.

The following table shows the salary of 7 people in an office last year.
Name Income
Andy £13500
Bevan £27500
Cheryl £13750
Deva £79000
Elliott £18750
Frankie £27500
Grace £15000
a) Work out the mean income to 2 DP.
b) Deva was given a large bonus for 30 years service.
Excluding Deva's income, what was the mean income for the remaining 6 workers to 2 DP?
Answer:
Mean of worker's salary = £27,785.71 (Approx.)Mean of worker's salary[Excluding Deva's income] = £16,500 (Approx.)Step-by-step explanation:
Given:
Total number of worker = 7
Find;
1] Mean of worker's salary
2] Mean of worker's salary[Excluding Deva's income]
Computation:
Mean = Sum of all observation / Total number of observation
1] Mean of worker's salary = [13,500 + 27,500 + 13,750 + 79,000 + 18,750 + 27,500 + 15,000] / 7
Mean of worker's salary = [194,500] / 7
Mean of worker's salary = £27,785.71 (Approx.)
2] Mean of worker's salary[Excluding Deva's income] = [13,500 + 27,500 + 13,750 + 18,750 + 27,500 + 15,000] / 6
Mean of worker's salary[Excluding Deva's income] = [115,500]/7
Mean of worker's salary[Excluding Deva's income] = £16,500 (Approx.)

If m ABC = 122°, and mZABD = 71°,
then mZDBC = [ ? 1°
Enter
Answer:
[tex]122 - 71 = 51 \\ m < 51[/tex]
Answer:
DBC= 40˚
Step-by-step explanation:
Since we already know what ABC and ABD is we could use these information to get what DBC is.
Since ABD and DBC adds together to sum up to ABC we could use this info to create this equation:
ABD+DBC=ABC
Replace ABD and ABC with the number that it is equal to
71˚+DBC=112˚
Move 71˚ to the other side by subtracting
DBC=112˚-72˚
Which is 40˚
So the answer is 40˚

Step-by-step explanation:
P(appetizers with cheese) = number with cheese / total = 1/5
P(entrees with cheese) = number with cheese / total = 1/3
It is the P(a) + P(b) - P(a and b)
We cannot double count the cheese and cheese event)
P( cheese and cheese) = 1/3 * 1/5 = 1/15
1/5 + 1/3 - 1/15
3/15 + 5/15 -1/15

The number of students using a cell phone application doubles every seven days. The initial number of users is 100. Write an equation for f(t) which represents the number of students who are using the application after t days
Answer:
Following are the solution to the given question:
Step-by-step explanation:
Initial number of users
[tex]N_0=100[/tex] [tex]\text{growth rate=doubles every seven days}[/tex]
[tex]100\% \longrightarrow 7\ days\\\\\frac{100}{100} \longrightarrow 7\ days\\\\1 \longrightarrow 7\ days\\\\[/tex]
When:
[tex]N=N_0\ 2^{rt}\\\\[/tex]
[tex]=100\times 2^{rt}\\\\=100\times 2^{t\cdot \frac{1}{7}}\\\\=100\times 2^{ \frac{t}{7}}\\\\[/tex]
Checking the value:
After 14 days:
[tex]N=100\times 2^{ \frac{14}{7}}=400\\\\100 \overset{100\ days}{\rightarrow} 200 \overset{7 \ days}{\rightarrow}\ 400[/tex]

Answer:
-6
Step-by-step explanation:
since x = - 5 is < 3
for x < 3,
f(x) = 3x + 9
placing the value of x as - 5
f(x) = 3× (-5) + 9
= -15 + 9

Jorden has already saced 35$. He wants to have 80$. He earns $6 per hour doing yard work which function will help jorden gigure out how many more hours [h] he needs to work
Answer:
Number of hours= 7.5
Step-by-step explanation:
Giving the following information:
Amount saved= $35
Hourly rate= $6
Total objective= $80
To calculate the number of hours to be saved, we need to use the following formula:
Number of hours= difference needed / hourly rate
Number of hours= (80 - 35) / 6
Number of hours= 45/6
Number of hours= 7.5

Answer:
I dont see the whole question
Step-by-step explanation:
Answer:
Remember the relation:
Distance = Speed*Time.
Then if we define:
y = distance
x = time
Speed = 50km/hr
Then we can write the relation between distance and time is:
y = (50km/hr)*x
This is the equation we need to graph.
To graph it, we can just find two points of that equation, and then draw a line that connects them:
For example if we have x = 0hr then:
y = (50km/hr)*0hr = 0km
then we have the point (0hr, 0km)
If now we use the point x = 1hr, then:
y = (50km/hr)*1hr = 50km
Then we also have the point (1hr, 50km)
Now we can draw these two points and connect them by a line, that line is the graph of the equation.
The graph of the equation can be seen below:

Answer:
r = 16, q = 16√2
Step-by-step explanation:
This is a 45° 45° 90° triangle. In this type of triangle, the legs of said shape will be equal and the hypotenuse will be the leg length multiplied by √2.
Therefore, r = 16 and q = 16√2.
Answer:
r = 16, c = 22.63
Step-by-step explanation:
tan 45° = 16/r
r = 16/ tan 45°
r = 16
c² = a² + b²
c² = 16² + 16²
c² = 256 + 256
c² = 512
c = 22.63

Write the explicit formula for the sequence below and use it to find the 47th term:
-3, 5, 13, 21, . . .
Given:
The sequence is:
[tex]-3,5,13,21...[/tex]
To find:
The explicit formula for the given sequence then find the 47th term.
Solution:
We have,
[tex]-3,5,13,21...[/tex]
The difference between two consecutive terms are:
[tex]5-(-3)=8[/tex]
[tex]13-5=8[/tex]
[tex]21-13=8[/tex]
The given sequence has a common difference. So, the given sequence is an arithmetic sequence with first term -3 and common difference 8.
The explicit formula for an arithmetic sequence is:
[tex]a_n=a+(n-1)d[/tex]
Where, a is the first term and d is the common difference.
Putting [tex]a=-3[/tex] and [tex]d=8[/tex] in the above formula, we get
[tex]a_n=-3+(n-1)8[/tex]
[tex]a_n=-3+8n-8[/tex]
[tex]a_n=8n-11[/tex]
Putting [tex]n=47[/tex], we get
[tex]a_{47}=8(47)-11[/tex]
[tex]a_{47}=376-11[/tex]
[tex]a_{47}=365[/tex]
Therefore, the explicit formula for the given sequence is [tex]a_n=8n-11[/tex] and the 47th term is 365.

The sum of two numbers is 44. The smaller number is 14 less than the larger number. What are the numbers?
Larger Number:
Smaller Number:
Answer:
Smaller number = 15
Larger number = 29
Step-by-step explanation:
Let smaller number be S
Let larger number be L
Given :
Sum = 44. That is , S + L = 44
Smaller number is 14 less than larger number. That is , S = L - 14
Therefore the equations are :
S + L = 44 ------(1)
S = L - 14 ------(2)
Substitute (2) in ( 1 )
(L - 14 ) + L = 44
L - 14 + L = 44
2 L = 44 + 14
2 L = 58
L = 29
Substitute L in (1) : S = L - 14 = 29 - 14 = 15
Answer:
Larger Number: 29
Smaller Number: 15
Step-by-step explanation:
By assigning the letters "L" and "S", to the larger number and smaller number respectively, we can solve this using simultaneous equations:
L+S = 44
L-14 = S
By substituting S = L-14 into the first equation, we get:
L+L-14 = 44 (add 14 to both sides)
L+L = 58 ( divide by 2 as L+L becomes 2L)
L=29
When L= 29, S= 29-14 which is 15

Suppose a city with a population of 700,000 has been growing at a rate of 7% per year. If this rate continues, find the population of this city in 25 years. The population in 25 years will be approximately...?
Answer:
approximately 1,925,000
Step-by-step explanation:
700,000 * 0.07 = 49,000 this would be the growing rate per year.
49,000 * 1,225,000 this would be the population grown in 25 years.
700,000 + 1,225,000 = 1,925000 this would be the total population that was in the city and the population that has grown in the 25 years.

Use SOH CAH TOA to identify the Cosine C.
Explanation:
This is because cosine is the ratio of adjacent over hypotenuse
cos(angle) = adjacent/hypotenuse
In this case, 20 is the adjacent side to the reference angle C. The hypotenuse is the longest side 29.
