The general solution of the given second-order differential equation is

y = [tex]e^{5t}[/tex]([tex]c_{1}[/tex]cost + [tex]c_{2}[/tex]sint).

In the given question we have to find the general solution of the given second-order differential equation.

The given second-order differential equation is:

y'' − 10y' + 26y = 0

We can write this equation as

d^2(y)/dx^2 − 10dy/dx + 26 = 0

Let d/dx = D

then, d^2/dx^2 = D^2

Now the equation is:

(D^2 − 10D + 26)y = 0

Now solving the equation as a quadratic equation.

m^2 − 10m + 26 = 0

m = [tex]\frac{-(-10)\pm\sqrt{(-10)^2-4\times1\times26}}{2\times1}[/tex]

m = [tex]\frac{10\pm\sqrt{100-104}}{2}[/tex]

m = [tex]\frac{10\pm\sqrt{-4}}{2}[/tex]

m = [tex]\frac{10\pm2i}{2}[/tex]

m = 5±1

Now the general equation for quadratic equation is

y = [tex]e^{at}[/tex]([tex]c_{1}[/tex]cosbt + [tex]c_{2}[/tex]sinbt)

As a = 5 and b = 1

Now the general solution of the given second-order differential equation is y = [tex]e^{5t}[/tex]([tex]c_{1}[/tex]cost + [tex]c_{2}[/tex]sint).

2(2x-5)-7(2x-1)=3

Multiply both sides of the equation by 14, the least common multiple of 7,2.

2(2x−5)−7(2x−1)=42

Use the distributive property to multiply 2 by 2x−5.

4x−10−7(2x−1)=42

Use the distributive property to multiply −7 by 2x−1.

4x−10−14x+7=42

Combine 4x and −14x to get −10x.

−10x−10+7=42

Add −10 and 7 to get −3.

−10x−3=42

Add 3 to both sides.

Answer:

The ball will return to the ground at t = 16 seconds, so the correct answer is D.

Step-by-step explanation:

To find when the ball will return to the ground, we need to find the time at which the ball's height is equal to 0. We can do this by setting the height equation equal to 0 and solving for t.h = -16t^2 + 100t + 2

0 = -16t^2 + 100t + 2

-2 = -16t^2 + 100t

-0.125t = -2

t = 16

Answer:

B. 6.3 sec

Step-by-step explanation:

To find the time when the ball will return to the ground, we need to find the value of t when h is equal to 0 (since height = 0 means the ball is on the ground). We can do this by substituting 0 for h in the given equation and solving for t.

So, let's start by substituting 0 for h:

h = -16t^2 + 100t + 2

0 = -16t^2 + 100t + 2

-16t^2 + 100t + 2 = 0

This is a quadratic equation, which we can solve using the quadratic formula:

t = (-100 +/- sqrt(100^2 - 4(-16)(2)) ) / (-2(-16))

t = (-100 +/- sqrt(10000 + 128)) / 32

t = (-100 +/- sqrt(10128)) / 32

t = (-100 +/- 100.64) / 32

t = (200.64) / 32

t = 6.3125

Since the ball is projected into the air and then falls back down to the ground, the time when it returns to the ground must be a positive value. Therefore, the solution to the problem is t = 6.3 sec

The school district have to  purchase 8 laptops for the cost to be the same for both companies.

What is sequence?

A sequence is an enumerated group of items in mathematics where repetitions are permitted and order is important. It has members, just like a set does. The length of the sequence is the number of elements.

Given that the company 1 offers:

The cost of 1 laptop is $425.

The cost of 3 laptop is $475.

The cost of 5 laptop is $525.

The difference of cost 1 laptop to cost 3 laptop = the difference of cost 3 laptop to cost 5 laptop = $50

The company 2 offers:

The cost of 1 laptop is $250.

The cost of 3 laptop is $350.

The cost of 5 laptop is $450.

The difference of cost 1 laptop to cost 3 laptop = the difference of cost 3 laptop to cost 5 laptop = $100

Take the cost as a sequence:

The common difference of first sequence is 50/2 = 25.

The common difference of second sequence is 100/2 = 50.

Assume that the school district needs to buy n computer.

The nth term of a sequence is a + (n - 1)d, where a is the first term, d is common difference.

The nth term of the first sequence is 425 + (n - 1) 25

The nth term of the second sequence is 250 + (n - 1) 50

According to question,

425 + (n - 1) 25 = 250 + (n - 1) 50

425 + 25n - 25 = 250 + 50n - 50

25n - 50n = 250 - 50 - 425 + 25

- 25n = -200

Answer: (A) One solution

The height of the object 1 second after it was launched is equals to 243.1 feet.

Let the launching velocity /initial velocity = u ft./s

and final velocity = 0 feet/sec , because at the maximum height, the final velocity of launching is '0'.

Maximum height , s = 3136 feet

time, t = 14 sec

Using the Equation of motion,

v² - u² = -2gs

where, v --> final velocity

u --> initial velocity

g --> acceleration due to gravity and it is a constant with value 9.8 m/sec²

s --> distance ( max. height)

plugging all known values in above formula,

0 - u² = -2 (9.8)(3136) = - 61465.6

=> - u² = - 61465.6

=> u² = 61465.6

=> u = √61465.6 = 247.92 ~ 248

=> u = 248 feet/sec

Now, the height, in feet, of the object 1 second after it was launched is

s = ut + (1/2)(-g)t²

=> s = 248(1) + (1/2)(-9.8)(1)

=> s = 248 - 4.9 = 243.1 feet

So, the required height is 243.1 feet.

The equation that shows the relationship is y = 6 + x

From the question, we have the following parameters that can be used in our computation:

Initial number of pieces = 6

Additional number of pieces per week = 1

The equation that shows the relationship is represented as

Number of pieces = Initial number of pieces + Additional number of pieces per week * Number of weeks

Substitute the known values in the above equation, so, we have the following representation

Number of pieces = 6 + 1 * Number of weeks

So, we have

Number of pieces = 6 + Number of weeks

The type of reasoning used to prove the remainder theorem is; Deductive reasoning

Logical reasoning involves using a given set of facts or data to deduce other facts by reasoning logically

There are 4 major types of reasoning here and they are;

1) Deductive reasoning; This is defined as a logical process in which a conclusion is based on the concordance of multiple premises that are generally assumed to be true.

2) Inductive reasoning; This is a method of drawing conclusions by going from the specific to the general.

3) Abductive reasoning; This is defined as a syllogism in which the major premise is evident but the minor premise and therefore the conclusion only probable.

4) Reasoning by analogy; This involves using a well known situation to assert something about a less well understood situation

In this case, we are told that since (x - 5) is a factor of the polynomial x² - 25, if he performs the long division (x² - 25) ÷ (x - 5), the remainder would be zero.

To solve this problem, we can set up a system of equations to represent the given information. Let x represent the cost of one steak burger. Then we can set up the following system of equations:

3x + 2(f) = 18

2x + 3(f) = 15.75

Where f represents the cost of one order of fries.

Subtracting the second equation from the first equation gives us:

x = 18 - 2(f) - 15.75 + 3(f)

= 18 - 15.75

= 2.25

Therefore, the cost of one steak burger is $2.25, which is answer choice C.

Option B is correct. It is a plot of the independent and dependent variables.

A scatter diagram is a type of plot or graph that uses Cartesian coordinates to display the values of two variables for a set of data. It is a simple yet powerful way to visualize the relationship between two variables.

The points on the plot represent the values of two variables, the independent variable (X-axis) and the dependent variable (Y-axis). Scatter diagrams provide a visual representation of the relationship between the two variables, which makes it easier to identify patterns such as linear or non-linear relationships.

They also can show correlations, or lack thereof, between two or more variables. Additionally, scatter diagrams can provide insight into the strength of the relationship between the two variables as well as how much of the variation in the dependent variable is explained by the independent variable. For example, a correlation coefficient of 1 indicates a perfect linear relationship, while a correlation coefficient of 0 indicates no relationship between the two variables.
