Answer: \((5+6)^2-(\frac{15}{5} )\) and solved is 118
Step-by-step explanation:
Finding the sum of 5 and 6 indicates the addition
5+6
It then says raise it to the power of two so let's put it in parenthesis so it can be solved before raising it to the power of two
\((5+6)^2\)
The quotient of 15 and 5 indicates division so we can put that in its own parenthesis too and then subtract it when solved.
\((5+6)^2-(\frac{15}{5} )\)
If you need to solve start by solving the parenthesis
\((5+6)^2-(\frac{15}{5} )\\ (11)^2-(3)\)
then raise 11 to the power of 2
121-3
finally, subtract

Qd=95−4P
Qs=5+P
a. What is Qd if P=5 ? b. What is P if Qs=20 ? β=9 c. If Qd=Qs, solve for P.
P = 90 is the solution for the given equation.
Given: Qd=95−4
PQs=5+P
To find Qd if P=5:
Put P = 5 in the equation
Qd=95−4P
Qd = 95 - 4 x 5
Qd = 75
So, Qd = 75.
To find P if Qs = 20:
Put Qs = 20 in the equation
Qs = 5 + PP
= Qs - 5P
= 20 - 5P
= 15
So, P = 15.
To solve Qd=Qs, substitute Qd and Qs with their respective values.
Qd = Qs
95 - 4P = 5 + P
Subtract P from both sides.
95 - 4P - P = 5
Add 4P to both sides.
95 - P = 5
Subtract 95 from both sides.
- P = - 90
Divide both sides by - 1.
P = 90
Thus, P = 90 is the solution for the given equation.

Answer:
slope = -1
Step-by-step explanation:
gradient = (difference in y)/(diffidence in X)
m = (7-3)/(-2-2)
m = 4/-4
m = -1
what is the slope-intercept form of the equation of the line that contains the points (-3,-3) and (4,5)
Answer:
\(y=1.14x+0.420\)
Step-by-step explanation:
Given the following question:
Point A = (-3,-3) = (x1, y1)
Point B = (4, 5) = (x2, y2)
To write the points in slope intercept form we must first calculate the slope using rise over run. Once we have the slope, we substitute the values into the formula for slope intercept which is y = mx + b and then solve for b to have our answer.
\(m=\frac{y2-y1}{x2-x1}\)
\(m=\frac{5--3}{4--3} =\frac{8}{7}\)
\(8\div7=1.14\)
\(m=1.14\)
Now that we have the slope substitute the values:
\(y=mx+b\)
\(y=-3\)
\(m=1.14\)
\(x=-3\)
\(-3=1.14(-3)+b\)
\(1.14\times-3=-3.42\)
\(-3=-3.42+b\)
\(-3.42+3.42=0\)
\(-3+3.42=0.42\)
\(0.42=b\)
\(b=0.42\)
\(y=1.14x+0.420\)
Your answer is "y = 1.14x + 0.420."

Eastman Publishing Company is considering publishing an electronic textbook about spreadsheet applications for business. The fixed cost of manuscript preparation, textbook design, and web site construction is estimated to be $172,000. Variable processing costs are estimated to be per book. The publisher plans to sell single-user access to the book for $4.
Through a series of web-based experiments, Eastman has created a predictive mode that estimates demand as a function of price. The predictive model is demand 4,000-sp, where p is the price of the e-book
(a) Construct an appropriate spreadsheet model for calculating the profit/s at a given single-user access price taking into account the above demand function. What is the profit estimated by your model for the given costs and single user access price (in dollars)
(b) Use Goal Seek to calculate the price (in dolars) that results in breakeven (Round your answer to the nearest cent.)
(c) Use a data table that varies price from $50 to $400 in increments of $25 to find the price (in dollars) that maximizes proft
(a) To construct an appropriate spreadsheet model for calculating profits at a given single-user access price, we need to consider the fixed costs, variable costs, and the demand function. Let's assume the single-user access price is represented by the variable "p."
The total cost for producing a certain number of books can be calculated as:
Total Cost = Fixed Cost + (Variable Cost per book) * (Number of books)
The number of books demanded can be estimated using the demand function:
Demand = 4,000 - sp
The revenue from selling the books can be calculated as:
Revenue = (Price per book) * (Number of books demanded)
Finally, the profit can be calculated as:
Profit = Revenue - Total Cost
Given the information provided, the fixed cost is $172,000, and the variable cost per book is $4.
Let's calculate the profit for a single-user access price of $4:
Total Cost = $172,000 + ($4 * Number of books)
Revenue = ($4 * Demand)
Profit = Revenue - Total Cost
Substituting the demand function:
Profit = ($4 * (4,000 - 4p)) - ($172,000 + ($4 * Number of books))
(b) To calculate the price that results in breakeven, we can use the Goal Seek feature in the spreadsheet software. We set the profit formula to be equal to zero and use Goal Seek to find the corresponding price that makes the profit zero. By doing this, we find the price at which the revenue covers all costs, resulting in breakeven.
(c) To find the price that maximizes profit, we can use a data table in the spreadsheet software. We create a data table that varies the price from $50 to $400 in increments of $25 and calculate the profit for each price. By analyzing the data table, we can identify the price that yields the highest profit.
The specific calculations for parts (b) and (c) require the actual spreadsheet data and formulas to be implemented in the software. The steps mentioned above provide a general approach to address those questions.

L=-5.6 +1.1d
After tracking a species of migratory bird for ten years, the latitude, L, in degrees north for the
species of bird d days after March 1 and until May 1 is approximated by the equation above. By
approximately how many degrees north does the latitude of the bird species change each day
between March 1 and May 1?
Considering the given linear function, the latitude of the bird species changes on average 1.1º a day between March 1 and May 1.
What is the linear function that models this situation?The Latitude L, in degrees north, in d days after March 1 is given by:
L = -5.6 + 1.1d.
Hence, on March 1, which is the day 0, the Latitude is given by:
L(0) = -5.6 + 1.1 x 0 = -5.6º.
May 1st is 61 days after March 1st, hence the Latitude on this day is given by:
L(61) = -5.6 + 1.1 x 61 = 61.5º.
Hence the average rate of change of the latitude is given by the change in the output, which is the latitudes, by the change in the input, which is of 61 days, hence:
[61.5 - (-5.6)]/61 = 1.1.

You finally put the order in for the family shirts! You order 40 shirts and two-
fifths of the shirts are children-sized. How many of the shirts that you ordered
are adult-sized shirts?
There are 24 adult-sized shirts in the Order.
The number of adult-sized shirts in the order, we need to calculate two-fifths of the total number of shirts and subtract it from the total.
Given that the order consists of 40 shirts and two-fifths of the shirts are children-sized, we can calculate the number of children-sized shirts as follows:
Children-sized shirts = (2/5) * 40
= (2/5) * 40
= 16
Since the remaining shirts are adult-sized, we can find the number of adult-sized shirts by subtracting the number of children-sized shirts from the total number of shirts:
Adult-sized shirts = Total shirts - Children-sized shirts
= 40 - 16
= 24
Therefore, there are 24 adult-sized shirts in the order.

suppose that integral of (f(x) dx) from (3) to (4)= -4. find integral of (9 f(u) du) from (3) to (4)and integral of (- f(u) du) from (3) to (4)
The definite integral of -f(u) from 3 to 4 is 4.
Since we know the definite integral of f(x) from 3 to 4 is -4, we can use the following formula to find the definite integral of 9f(u) from 3 to 4:
∫[3 to 4] 9f(u) du = 9 ∫[3 to 4] f(u) du
This is because we can factor the constant 9 outside of the integral, and we're left with the integral of f(u) from 3 to 4.
So, we can substitute -4 for the integral of f(x) from 3 to 4:
∫[3 to 4] 9f(u) du = 9(-4) = -36
Therefore, the definite integral of 9f(u) from 3 to 4 is -36.
Now, let's find the definite integral of -f(u) from 3 to 4. We can use a similar method:
∫[3 to 4] -f(u) du = -∫[3 to 4] f(u) du
This is because we can factor out the constant -1, which changes the sign of the integral. So, we can substitute -4 for the integral of f(x) from 3 to 4:
∫[3 to 4] -f(u) du = -(-4) = 4
Therefore, the definite integral of -f(u) from 3 to 4 is 4.

(hint: the formula for the volume of a cone is v
When the pile is 22 feet high, the height of the pile changes to 20/1089π.
Given (dV)/(dt) = 20, h = 22 feet , dh /dt =?
The volume of cone is V = 1/3 * pi * r ^ 2 * h
d=3h
2r = 3h
r = (3h)/2
V = 1/3 * pi * r ^ 2 * h

The value of the relative frequency distribution of the first interval, having a frequency of 14, and the total frequency given is 40, is 0.35.
In a Relative Frequency Distribution, we list how often a data value appears and scale it using the total frequency.
The sum of Relative Frequencies adds to 1.
In the question, we are informed that the first interval has a frequency of 14.
This implies that the data appears 14 times in the first interval.
Also, we are told that the total frequency is 40.
Thus, the relative frequency can be calculated as the ratio of the frequency of the interval to the total frequency.
Therefore, Relative frequency = 14/40 = 0.35.
Thus, the value of the relative frequency distribution of the first interval, having a frequency of 14, and the total frequency given is 40, is 0.35.

a connected planar graph has 9 vertices having degrees 2, 2, 2, 3, 3, 3, 4, 4, and 5. how many edges are there? how many faces are there?
The given connected planar graph has 15 edges and 8 faces.
To find the number of edges in a connected planar graph with the given degrees of vertices, we can use the formula known as Euler's formula. Euler's formula states that for a connected planar graph, the number of vertices (V), edges (E), and faces (F) are related by the equation V-E+F=2.
Using the given information, we can calculate the total number of vertices as 9. The sum of the degrees of these vertices is 30, which means the total number of edges can be calculated as (30/2) = 15.
To find the number of faces, we can use another formula: F = E - V + 2. Substituting the values we know, we get F = 15 - 9 + 2 = 8. Therefore, the given connected planar graph has 15 edges and 8 faces.
It's worth noting that the degrees of the vertices play an important role in determining the structure of a planar graph. In particular, the fact that all the vertices in this graph have low degree means that it is likely to have a simple and straightforward structure. By contrast, if the degrees were all high, the graph would be more complex and harder to visualize.
