C. y(x)=xe^x
D. y(x)=e^x
E. y(x)=xe^−x
F. y(x)=−e^x
G. y(x)=0

Answers

Answer 1

Option (B) and (E) functions are solutions of the differential equation y′′+2y′+1y=0.

What is differential equation?

An equation known as a differential equation describes the derivative or derivatives of an unknown function. Because they are equations involving a function and its derivatives (where the variable is a function rather than a number) (the functions obtained by differentiating it). Save this response. Common differential equations are used in everyday life to compute the flow of electricity, the motion of an item back and forth like a pendulum, and to illustrate the principles of thermodynamics. Additionally, in medical terminology, they are employed to graphically monitor the progression of illnesses.

Given that,

y′′+2y′+1y = 0

A.E = m² + 2m + 1 = 0

or, (m + 1)² = 0

or, m = ± 1

y = (c₁ + c₂x)e⁻ˣ

y = c₁e⁻ˣ + c₂xe⁻ˣ

Thus, option (B) and (E) are solutions  of the differential equation:

y′′+2y +1y = 0.

Could the lengths 6 8 and 15 represent the sides of the triangle?

Answers

The lengths 6, 8 and 15 cannot represent the sides of the triangle. The solution has been obtained by using the triangle inequality theorem.

What is the triangle inequality theorem?

The triangle inequality theorem outlines the relationships between a triangle's three sides. According to this theorem, the lengths of any triangle's two shorter sides add up to be longer than the triangle's third side. In other terms, this theorem states that the shortest path between any two places is always a straight line.

We are given the lengths to be 6, 8 and 15.

Using the triangle inequality theorem,

⇒ 6 + 15 > 8

⇒ 21 > 8

Also,

⇒ 8 + 15 > 6

⇒ 23 > 8

Also,

⇒ 6 + 8 > 15

But,

⇒ 14 < 15

Hence, the lengths 6, 8 and 15 cannot represent the sides of the triangle.

find the value of the integral ∫ (∇ × a® ).® if the vector a® = eˆ eˆ eˆ and is the surface defined by the paraboloid = 1 − 2 − 2 , where ≥ 0.

Answers

The integral is equal to zero, since the divergence of a constant vector is always zero.

The integral ∫ (∇ × a® ).® is equal to zero. This is due to the fact that the curl of a constant vector is always zero. The vector a® is given to be eˆ eˆ eˆ, therefore it is a constant vector. Since the divergence of a constant vector is always zero, the integral is equal to zero.

To further illustrate this point, we can expand the integral in terms of its components. ∇ × a® is equal to 0 as it is the curl of a constant vector. Similarly, a® .® is equal to 0 since the inner product of two constant vectors is always zero. Therefore, the integral is equal to 0.

The surface defined by the paraboloid is not used in this calculation, as the surface does not affect the value of the integral. The surface is used to define the range of the integral, but not to calculate the value of the integral itself.

-2.25 is larger when it compares to -3, because when you order negative numbers, the larger the number after the negative sign, the smaller the number actually is. This means -2.25 > -3

What is negative numbers?

On a number line, numbers always move from right to left and grow (become "more positive") in that direction. The numbers to the right are bigger than the numbers to the left, while the numbers to the left are smaller. Numbers with a minus sign before them are considered negative numbers. They could be fractions, decimals, or integers. Negative numbers include, for instance, -4, -15, -4/5, and -0.5. A negative number in mathematics represents the reverse. A negative number is one that is less than zero in the real number system. Negative numbers are frequently used to indicate how great a loss or a shortage is.

-2.5>-3 because the bigger a negative number is like -15,-18, etc the smaller it’s value actually gets so -2.5 is greater because it is closer to 0 on a number line.

Given the following table with selected values of the linear functions g(x) and h(x), determine the x-intercept of g(h(x))

Answers

The x-intercept of the composition is x = -1/2.

How to find the x-intercept of the composition?

Remember that a linear function can be written as:

y = a*x + b

Where a is the slope and b is the y-intercept.

If a liear function passes through two points (x₁, y₁) and (x₂, y₂), then the  slope is:

a = (y₂ - y₁)/(x₂ - x₁)

For g(x) we can use (-1, 2) and (1, 6), the slope is:

a = (6 - 2)/(1 + 1) = 2

Then the function is something like:

g(x)=  2x + b

To find the value of b, we use again the point (1, 6)

g(1) = 6 = 2*1 + b

      6 - 2 = b

         4 = b

So:

g(x) = 2x + 4

Now the same for h(x), we can use the points (-1, -1) and (1, 7), we will get:

a = (7 + 1)/(1 + 1) = 4

h(x) = 4x + b

Using the point (1, 7)

h(1) = 7 = 4*1 + b

        7 - 4 = b

        3 = b

h(x) = 4x + 3

The composition is:

g( h(x)) = 2*h(x) + 4

           = 2*(4x + 3) + 4

            = 8x + 10

The x-intercept is the value of x such that:

0 = 8x + 4

-4 = 8x

carbon-14 has a half-life of 5,730 years. if a sample contains 80 mg originally, how much is left after 17,190 years?

Answers

Answer:

After 17,190 years, the amount of carbon-14 left would be approximately 5 mg.

The half-life of carbon-14 is 5,730 years, which means that every 5,730 years, half of the remaining carbon-14 decays. To calculate the amount of carbon-14 remaining after 17,190 years, we can use the formula:

A = A0 * (1/2)^(t/T)

where:

A0 is the initial amount (80 mg)

t is the time elapsed (17,190 years)

T is the half-life (5,730 years)

A = 80 * (1/2)^(17,190/5,730)

A = 80 * (1/2)^3

A = 80 * (1/8)

A = 10 mg * 1/2

A = 5 mg

What is the math formula for mortgage?

These factors include the total amount you're borrowing from a bank, the interest rate for the loan, and the amount of time you have to pay back your mortgage in full. For your mortgage calc, you'll use the following equation: M = P [ i(1 + i)^n ] / [ (1 + i)^n – 1].

Calculate H = P*J, this is your current monthly interest.

Calculate C = M - H, this is your monthly payment minus your monthly interest, so it is the amount of principal you pay for the month.

Calculate Q = P - C, this is the new balance of your principal of your loan.

P = the payment.

L = the loan value.

c = the period interest rate, which consits of dividing the APR as a decimal by the frequency of payments. ...

n = the total number of payments in the life of the loan (for monthly loan payments this is the loan term in years times twelve)

With given data:

123,500 x 1.05% =$1,296.75 percentage of the fee.

Total mortgage brokerage fees

Answer:

a) $2125

b) $2000

Step-by-step explanation:

In this problem, we are asked to solve for the manufacturing price of different printers if the printer company sells their printers at a price that makes them 25% profit, assuming there are no extra expenses.

We can solve this type of problem by manipulating ratios, like for example:

manufacturing price : sale price

           100                  :       125

This ratio represents the the sale price being 25% more than the manufacturing price.

a) We can equate the above ratio to the ratio of the manufacturing price (in this problem, $1700) to the sale price of the printer (represented by x).

100 : 125 = 1700 : x

This can be solved for x when the ratios are represented as fractions.

[tex]\dfrac{100}{125} = \dfrac{1700}{x}[/tex]

↓ simplify the fraction on the left side

[tex]\dfrac{4}{5} = \dfrac{1700}{x}[/tex]

↓ cross multiply

[tex]4x = 1700 \cdot 5[/tex]

↓ divide both sides by 4

[tex]x=\$ \, 2125[/tex]

So, the price that the customer would pay for a printer that the company bought for $1700 is $2125.

b) We can solve in the same way that we did for section a.

However, this time, the variable (y) represents the manufacturing price, NOT the sale price.

100 : 125 = y : 2500

↓ rewrite with fractions

[tex]\dfrac{100}{125} = \dfrac{y}{2500}[/tex]

↓ simplify the fraction on the left side

[tex]\dfrac{4}{5} = \dfrac{y}{2500}[/tex]

↓ cross multiply

[tex]5y = 2500 \cdot 4[/tex]

↓ divide both sides by 5

[tex]y = \$ \, 2000[/tex]

So, the price that the company would pay for a printer that a customer buys for $2500 is $2000.

Given the points by which a basketball team either won or lost 6 games.

- Won by 7 points = +7

- Lost by 10 points = -10

- Won by 8 points = +8

- Won by 11 points = +11

- Lost by 2 points = -2

- Won by 10 points = +10

Thus;

Mean difference of the 6 games is;

= (+7 - 10 + 8 + 11 - 2 + 10)/6

= 24/6

= 12

Hence, the mean difference in game scores over the six games is 12

22 miles in 20 minutes A < B > C = 38 miles in 30 minutes

Answers

It is found that 22 miles in 20 minutes is LESS

What is Algebra?

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

We have to compare the two rates:

=> 22 miles in 20 minutes

=> 38 miles in 30 minutes

Let's simplify each rate by finding the speed, which is distance divided by time.

That is:

Speed = distance/time

For the first one:

s = 22/20 = 1.1 milesl/min

For the second one:

s = 38/30 = 1.27 milesl/min

Since 1.1 is less than 1.27, so, 22 miles in 20 minutes is less than 38 miles in 30 minutes.

Six Republicans and six Democrats orally cast their vote in the U.S. Senate. In how many orders can they vote they must alternate Republican, Democrat, Republican, Democrat, and so on, and if a Republican must always be the first to vote?

Answers

If Six Republicans and six Democrats orally cast their vote in the U.S. Senate , if they are alternate Republican, Democrat, Republican, Democrat, and so on, and if a Republican must always be the first to vote then the number of ways in which they can vote is 518400 ways .

the number of Republicans for voting is = 6 ;

the number of Democrats for voting is = 6 ;

so , total number of voters is = 12 ,

they have to vote alternately starting with a Republicans .

the first republican has to choose from = ⁶C₁ = 6 ;

the second republicans has to choose from the remaining 5 republicans , = ⁵C₁ = 5 ;

Similarly following the pattern ,

we get ;

Total chances of required way of casting votes ;

= 6×6×5×5×4×4×3×3×2×2×1×1

= (1×2×3×4×5×6)²

= (6!)² = (720)² = 518400 ways .

Therefore , the number of ways of voting is 518400 ways .

Answers

When u, v are nonzero vectors, then span{u, v} contains the line through u and the origin, as well as the line through v and the origin, this statement is false.

The span of two nonzero vectors, u and v, is the set of all linear combinations of u and v. This can be a line, a plane, or even the entire space, depending on the vectors u and v. In general, the span of two nonzero vectors does not contain the line through each vector and the origin, unless the two vectors are collinear (i.e. they lie on the same line).

Though most parts of France agreed to this, lawmakers in Paris hesitated. Pierre Lemerre the Younger made the case for the slaves. "All men are equal," he insisted in 1716exactly sixty years before the Declaration of Independence.To say that "all men are equal" in 1716, when slavery was flourishing in every corner of the world and most eastern Europeans themselves were farmers who could be sold along with the land they worked, was like announcing that there was a new sun in the sky. In the Age of Sugar, when slavery was more brutal than ever before, the idea that all humans are equal began to spreadtoppling kings, overturning governments, transforming the entire world.Sugar was the connection, the tie, between slavery and freedom.Clarkson and others who believed as he did, who in the coming decades would be called abolitionists, realized that while that link gave the English a stake in slavery, it also gave the antislavery forces an opportunity. If they could reverse the flowmake the horrors of slavery visible to those who benefited from itthey might be able to end the vile practice forever.The abolitionists were brilliant. They created the most effective public relations campaign in history, inventing techniques that we use to this day. When he spoke, Clarkson brandished whips and handcuffs used on slaves; he published testimonials from sailors and ship doctors who described the atrocities and punishments on slave ships. When Olaudah Equiano published his memoir, he educated his readers about the horrors of the slave trade. And then, when the English began to understand what slavery really was, Clarkson and others organized what we would call a boycott of "the blood-sweetened beverage."Which statement best explains how the authors develop their claim across the two passages?Both passages use evidence to develop the claim that the general public needed to know about the terrors of involuntary servitude.Both passages use evidence to develop the claim that Eastern European farmers and enslaved people on sugar plantations shared a common goal.Both passages use evidence to show that knowledge of the extreme brutality of the sugar trade changed viewpoints about enslavement.Both passages use evidence to support the claim that lawmakers had more power and influence than abolitionists had. is the standard enthalpy of combustion of glucose likely to be higher or lower at blood temperature than at 25c?
