Step-by-step explanation:

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).

Answer:

y > -2/3x + 2, y [tex]\geq[/tex] x

[tex]\left \{ {{y > -2/3x + 2} \atop {y \geq x}} \right.[/tex]

Step-by-step explanation:

Knowledge Needed

A system of linear inequalities is graphing 2 lines.

If the line's y side is less than it's x-side (y </ [tex]\leq[/tex] x), shade below.

If the line's y side is greater than it's x-side (y </ [tex]\leq[/tex] x), shade above.

If the line is dotted, it is < or >.

If the line is filled in, it is [tex]\leq[/tex] or [tex]\geq[/tex].

Where both regions are shaded is the solution.

Question

Examine the dotted line.

1) We know it is < or > because it is dotted.

2) We know it is y > .... because if it was less than, it would be shaded below, which is impossible because the shaded region is above.

3) We know the y-intercept, when x=0, is 2.

4) We know the slope, how much the y-value of a line changed when the x-value changes by 1, is -2/3.

y > -2/3x + 2

Examine the solid line.

1) We know it is [tex]\geq[/tex] or [tex]\leq[/tex] because it is solid.

2) We know it is y [tex]\geq[/tex] .... because if it was less than, it would be shaded below, which is impossible because the shaded region is above.

3) We know the y-intercept, when x=0, is 0.

4) We know the slope, how much the y-value of a line changed when the x-value changes by 1, is 1.

y [tex]\geq[/tex] 1x + 0

y [tex]\geq[/tex] x

The solution to the linear inequality is when both lines are shaded in (true), which means both lines are the solution together.

y > -2/3x + 2, y [tex]\geq[/tex] x

Answer:

------------------------------

Find the lines first, then determine inequalities based on the shaded region and types of lines.

One line has positive slope and passes through the origin. Its x and y-coordinates are same, hence it is:

The shaded region is above this line and the line is solid, therefore the inequality is:

The second line has a negative slope and it has y-intercept at (0, 2), x- intercept at (3, 0).

Its slope is m = (0 - 2)/(3 - 0) = - 2/3.

So the line is:

Again, the shaded region is above the line, and the line is dashed, hence the inequality is:

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.

Answer: root 70

Step-by-step explanation:

starting info:

KL = 2NM

KM = 20

NO = 7

Using the fact the ratio of similar sides must be equal:

KL/NO = KM/NM

Therefore sub in values…

KL/7 = 20/NM

As KL = 2NM

2NM/7 = 20/NM

Rearrange:

2(NM)^2 = 140

(NM)^2 = 70

NM = root(70)

(Obviously take positive as can’t have negative length)

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.

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.

Now, this is an example of deductive reasoning because it has used the initial premise to draw a conclusion on the remainder.

P (two red counters) = 1/15

P (two green counters) = 2/15

P (two yellow counters) = 1/145

P (white and then red) = 1/30

P (white or yellow, in either order but not both) = 3/10

P (white or red, in either order but not both) = 2/5

The probability of drawing a white or yellow counter first and then any

color second = 7/30

It is the chance of an event to occur from a total number of outcomes.

The formula for probability is given as:

Probability = Number of required events / Total number of outcomes.

We have,

Number of red counters = 3

Number of green counters = 4

Number of yellow counters = 2

Number of white counters = 1

Total number of counters = 3 + 4 + 2 + 1 = 10

The probability of drawing 2 red counters.

= [tex]^3C_2[/tex] / [tex]^{10}C_2[/tex]

= 3 / 5 x 9

= 1/ 15

The probability of drawing 2 green counters.

= [tex]^4C_2[/tex] / [tex]^{10}C_2[/tex]

= 2 x 3 / 5 x 9

= 2/15

The probability of drawing 2 yellow counters.

= [tex]^2C_2[/tex] / [tex]^{10}C_2[/tex]

= 1 / 45

The probability of drawing one white and then one red counter.

= 1/10 x [tex]^3C_1[/tex]/[tex]^{9}C_1[/tex]

= 1/10 x 1/3

= 1/30

The probability of drawing one white or one yellow counter.

= 1/10 + 2/10

= 3/10

The probability of drawing one white or one red counter.

= 1/10 + 3/10

= 4/10

Answer:

16%

Step-by-step explanation:

Let's assume the original price of the item was Rs. 100.

After the price increased by 45%, the new price became:

New price = Original price + (45% of Original price)

New price = 100 + (0.45 x 100)

New price = Rs. 145

Now, the price dropped by 20% from the increased price of Rs. 145:

Final price = New price - (20% of New price)

Final price = 145 - (0.2 x 145)

Final price = Rs. 116

We can calculate the overall change in price by finding the difference between the final price and the original price:

Overall change in price = Final price - Original price

Overall change in price = 116 - 100

Overall change in price = 16

So, the price increased by Rs. 16. To find the percentage increase, we can use the formula:

Percentage increase = (Overall change in price / Original price) x 100%

Plugging in the values, we get:

Percentage increase = (16 / 100) x 100%

Percentage increase = 16%

Therefore, the price of the item increased by 16%.
