Explain why the functions with the given graphs can't be solutions of the differential equation dy dt = et(y − 1)2.
Answers
Please see attached document for the graphs:
The functions with the given graphs can't be solutions of
the differential equation dy dt = et(y − 1)2.
(a) won’t work, since it has negative slope on portions of its solutions. The
slope, e t (y − 1)2 , is a nonnegative function.
(b) won’t work, since it has positive slope at y = 1, where the slope must be flat.
Functions with given graphs cannot be solutions to the differential equation dy / dt = e^t(y-1)^2 because their graphs don't satisfy the conditions imposed by the equation, such as non-oscillatory behavior and non-linear variation with time.
Explanation:The question pertains to why certain functions represented by their graphs cannot be solutions to the differential equation dy / dt = et(y-1)2. The explanation lies in the structure of the given differential equation and the properties of function graphs.
Equation dy / dt = et(y-1)2 is a non-linear first order differential equation. To be a solution to this equation, a function's graph must satisfy certain conditions imposed by the equation. However, if certain function graphs represent an undefined curve or if their graphs demonstrate oscillatory behavior, they do not satisfy these criteria.
For instance, the differential equation demands non-oscillatory behavior as seen in the general solution provided in the reference: Yn(x) = Ce-Bx +De+Bx. This form describes a gradual attenuation of y(x), i.e., it does not oscillate. Similarly, if a graph represents a function that varies non-linearly with time (like In[A] vs. Time), it does not represent a solution to the differential equation as well.
Thus, the inability of certain function graphs to satisfy the conditions required by the given differential equation is the reason they cannot be its solutions.

The best leaper in the animal kingdom is the puma, which can jump to a height of 12 ft when leaving the ground at an angle of 45 degrees. with what speed in si units, must the animal leave the ground to reach that height?
Answers
1 feet = 0.3048 m
12 feet = 12 x 0.3048 = 3.6576 m
For a vertical jump:
velocity = sqrt(2gh) = sqrt(2 x 9.8 x 3.6576) = 8.4669 meter/second
Therefore, at an angle of 45 degrees:
velocity = vertical velocity / sin(45)
= 8.4669 / sin(45)
= 11.974 meter/second

It also means that the cannonball was launched above ground level.Yes, because the projectile hits the ground 30 feet from the cannonWhich methods can be used to evaluate the polynomial?1. f(x) is the output of the projectile function, where;
x = The input which is the distance
Therefore;
f(x) = The vertical distance (height) of the cannonball at point x.2. The zeros are the points where the height, f(x) = 0
Therefore;
The zeros represent the points at which the cannonball is at ground level3. The net should be placed where the cannonball is expected to reach ground level.
Therefore;
The zeros indicates where the net should be placed4. The given polynomial can be equated to 0 as follows;
x² - 26·x - 120 = 0
5. x² - 26·x - 120 = x² - 30·x + 4·x- 120
Which gives;
x·(x - 30) + 4·(x- 30) = (x - 30)·(x + 4)
(x - 30)·(x + 4) = x² - 26·x - 1206. Where; (x + p)·(x + q) = a·x² + b·x + c
We have;
The values of p and q that give the correct factors are;
p = -30, and q = 47. The polynomial, -0.05·(x² - 26·x - 120) = 0 in factored form is therefore;
-0.05·(x² - 26·x - 120) = -0.05·(x - 30)·(x + 4)8. From the factors, we have;
-0.05·(x² - 26·x - 120) = -0.05·(x - 30)·(x + 4)
The roots of the equations, are given as follows;
x - 30 = 0 and x + 4 = 0
Which gives;
x = 30 or x = -49. The roots of the equation are therefore;
x = 30, and x = -410. The zeros for the function, are the values of x at which f(x) = 0
At x = 30 f(30) = -0.05 × (30² - 26 × 30 - 120) = 0
At x = -4, f(-4) = -0.05 × ((-4)² - 26 × (-4) - 120) = 0
The zeros of the function are x = 30, and x = -411. Yes. The zeros are the same as the roots found given that at the roots, f(x) = 0
12. The zeros of the function are x = 30 and x = -4, which are points at
which the projectile (cannonball) is at ground level. The negative zero, x
= -4, means that, apart from the point x = 30, the projectile can (also/only)
be at ground level at a point before the location where the projectile is
launched, (-4) which means that at the point at which the cannonball is
launched, which is at x = 0, the cannonball was not on the ground, but
at the lip of the barrel or at a more elevated position.
What the negative zero means are therefore;
It is a location before the point where the cannonball is launchedThe cannonball is launched from a height above ground level13. At 30 feet, x = 30, which is a zero of the function, and the cannonball
is at ground level, such that a net placed at 30 feet from the cannon

Complete the following steps to calculate the altitude of the parallelogram using area methods. The area of the sheet of paper is square inches. The combined area of the triangle cutouts is square inches. The area of the parallelogram is square inches. The altitude of the parallelogram rounded to two decimals is square inches.
Answers
Answer:
96
36
60
6.51
Step-by-step explanation:
The area of a shape is the amount of space it occupies.
The area of the paper is 96 square inchesThe combined area of the triangle cutouts is 36 square inchesThe area of the parallelogram is 60 square inchesThe altitude of the parallelogram is 6.51 inchesThe dimension of the paper is given as: 12-inch by 8-inch
So, its area is:
[tex]\mathbf{A_1 =12 \times 8}[/tex]
[tex]\mathbf{A_1 =96}[/tex]
The dimensions of the 4 right triangles are: Two 2 inches by 9 inches, and two 3 inches by 6 inches
So, the combined area is:
[tex]\mathbf{A_2 = 2 \times \frac 12 \times 2 \times 9 + 2 \times \frac 12 \times 3 \times 6}[/tex]
[tex]\mathbf{A_2 = 36}[/tex]
The area of the parallelogram is the difference between the areas of the paper and the four right triangles.
So, we have:
[tex]\mathbf{A_3 = A_1 - A_2}[/tex]
[tex]\mathbf{A_3 = 96 - 36}[/tex]
[tex]\mathbf{A_3 = 60}[/tex]
The area of a parallelogram is:
[tex]\mathbf{Area = Base \times Altitude}[/tex]
The base is given as 9.22
So, we have:
[tex]\mathbf{60 = 9.22\times Altitude}[/tex]
Divide both sides by 9.22
[tex]\mathbf{6.51 = Altitude}[/tex]
Rewrite as:
[tex]\mathbf{Altitude = 6.51}[/tex]

How tall is a building that casts a 73 foot shadow when the angle of elevation of the sun is 29
Answers
For this problem, we are given the angle and the ADJACENT length (73). We want to find the OPPOSITE side's length.
TOA
We must use the tangent function.
TOA helps us remember this relationship:
tan( theta ) = opposite / adjacent.
Plug in our values:
tan(29 degrees) = opposite / 73
Multiply by 73 to isolate "opposite" and solve for it.
73 * tan(29) = opposite.
Using a calculator, the answer is approximately 40.46 ft.
The height of the building is approximately 40.39 feet.
Explanation:To find the height of the building, we can use the concept of similar triangles. The height of the building is proportional to the length of its shadow. We can set up a proportion using the angle of elevation of the sun and the length of the shadow.
Let x be the height of the building. The proportion can be set up as:
(x / 73) = tan(29°)
Using a calculator, we can find the value of tan(29°) to be approximately 0.5543. Solving for x, we get:
x = (73 * 0.5543)
Therefore, the height of the building is approximately 40.39 feet.

The RideEm Bicycles factory can produce 160 bicycles in a day at a total cost of $10,100. It can produce 180 bicycles in a day at a total cost of $11,000. What are the company's daily fixed costs
Answers
Answer:
$2,900
Step-by-step explanation:
The additional 180 - 160 = 20 bicycles cost an additional $11,000 - 10,100 = $900. That means the 180 bicycles cost 9·$900 = $8100, and the fixed costs are $11,000 - 8,100 = $2,900.
_____
Each group of 20 bikes costs $900, so 9 groups of 20 (180 bikes) cost 9×$900 = $8100.
To find the daily fixed costs of RideEm Bicycles factory, subtract the variable cost from the total cost.
Explanation:To find the daily fixed costs of RideEm Bicycles factory, we need to determine the fixed cost component of the total cost. We can do this by subtracting the variable cost from the total cost. The formula for calculating fixed cost is:
Fixed Cost = Total Cost - (Variable Cost per Unit x Number of Units)
Using the given information:
Number of bicycles produced when the total cost is $10,100: 160 bicycles
Number of bicycles produced when the total cost is $11,000: 180 bicycles
Variable cost per unit: (Total Cost - Fixed Cost) / Number of Units

To be eligible for a basketball tournament, a basketball team must win at least 60% of its remaining games. If the team has 21 game remaining, how many games must the team win to qualify for the tournament?
Answers
The basketball team must win at least 13 out of their 21 remaining games to qualify for the tournament, as they need to win at least 60% of the games.
Explanation:To determine how many games a basketball team must win out of 21 to qualify for a tournament, given they must win at least 60%, we perform the following calculation:
First, multiply the total number of remaining games, which is 21, by 60% (or 0.60) to find the minimum number of games they need to win.Next, solve for the number: 21 games × 0.60 = 12.6.Since a team can't win a fraction of a game, they must win at least the next whole number of games, which is 13.Therefore, the team must win at least 13 games out of the remaining 21 to be eligible for the tournament.

How long will it take a $800 investment to be worth $900 if it is continuously compounded at 11% per year?
Answers
It takes approximately 1.083 years, or around 1 year and 1 month for an $800 investment to grow to $900 when continuously compounded with an 11% yearly interest rate.
Explanation:To calculate how long it will take for an $800 investment to grow to $900 with continuous compounding at an 11% yearly interest rate, we use the formula for continuously compounded interest, P = Pert, where P is the final amount, Pe is the original principal, r is the interest rate, and t is time in years.
Rearranging the equation to find t, we have, t = ln(P/Pe) / r.
Substitute P as $900, Pe as $800, and r as 0.11 into the formula.
Therefore, t = ln(900/800) / 0.11 = approximately 1.083 years or around 1 year and 1 month.

We deal from a well-shuffled 52-card deck. calculate the probability that the 13th card is the first king to be dealt.
Answers
Final answer:
The probability that the 13th card is the first king to be dealt is 1/52.
Explanation:
To calculate the probability that the 13th card is the first king to be dealt from a well-shuffled 52-card deck, we need to consider the number of favorable outcomes and the total number of possible outcomes. There are 4 kings in the deck, so the probability of the first king being the 13th card is 1/52.
Final answer:
The probability that the 13th card is the first king to be dealt in a shuffled 52-card deck is 1/13.
Explanation:
In a well-shuffled 52-card deck, the probability that the 13th card is the first king to be dealt can be calculated as follows:
First, let's determine the number of favorable outcomes. Since there are 4 kings in the deck, there are 4 possible kings that can be the first king dealt.
Next, let's determine the number of possible outcomes. Since there are 52 cards in the deck, there are 52 possible cards to be the 13th card dealt.
Therefore, the probability is calculated as:
Probability = Number of favorable outcomes / Number of possible outcomes
Probability = 4 / 52
Probability = 1 / 13
So, the probability that the 13th card is the first king to be dealt is 1/13.

If a company has 5 employees with annual salaries of $30,000, $50,000, $30,000, $80,000, and $70,000, respectively, what is the mean annual salary at the company?
Answers
Answer:
Annual mean salary at the company is $52,000
Step-by-step explanation:
Given : If a company has 5 employees with annual salaries of $30,000, $50,000, $30,000, $80,000, and $70,000, respectively.
We have to determine the mean annual salary at the company.
Consider the given salaries of 5 employee of the company
$30,000, $50,000, $30,000, $80,000, and $70,000
The annual mean salary at the company is the sum of salary of the employees divided by the number of employees.
Annual mean salary =[tex]\dfrac{30,000+50,000+30,000+70,000+80,000}{5}=\frac{2,60,000}{5}[/tex]
Thus, Annual mean salary at the company is $52,000
