By using the concept of kinetic energy, it is obtained that

Kinetic energy of the  airplane when its velocity is 300 m/s is 20250 megajoule

What is Kinetic energy?

Kinetic energy is the energy possessed by the body by virtue of its motion

If m is the mass of the body and v is the velocity of the body, then kinetic energy is given by the formula

Kinetic energy = [tex]\frac{1}{2} \times m \times v^2[/tex]

Let the mass of the airplane be m kg

Velocity = 220 m/s

Kinetic energy = [tex]\frac{1}{2} \times m \times (220)^2[/tex]

By the problem,

[tex]\frac{1}{2} \times m \times (220)^2 = 10890\times 10^6[/tex]

[tex]m = \frac{10890\times 10^6\times 2}{220\times 220}[/tex]

m = [tex]0.45 \times 10^6[/tex] kg

Now,

Velocity = 300 m/s

Kinetic energy = [tex]\frac{1}{2} \times 0.45 \times 10^6 \times 300 \times 300[/tex]

                        = [tex]20250 \times 10^6[/tex] J

                        = 20250 mega joules

Answer:

$5.92

Step-by-step explanation:

1.6 lbs. + 2.4 lbs. = 4 lbs.              

4 x 1.48 = 5.92

Since it doesn't specify whether the oranges and apples cost differently you can add both of them. Then you multiply it by 1.48 because that's the cost per pound.

The equation of a line is the mathematical function of a line thus the equation of the line that passes through the points (-4, -6) and (2, 8) will be y = (14/6)x + 10/3.

There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.

A linear equation or function is given as ;

y = mx + c

Here, m is the slope and is given as (y₂ - y₁)/(x₂ - x₁).

The slope of the line passing through (-4, -6) and (2, 8) will be,

m = (8 + 6)/(2 + 4)

m = 14/6

So, y = (14/6)x + c

Substitute,  (2, 8)

8 =  (14/6)2 + c

c = 8 - 14/3 = 10/3

Therefore, y = (14/6)x + 10/3

Hence "The equation of a line is the mathematical function of a line thus the equation of the line that passes through the points (-4, -6) and (2, 8) will be y = (14/6)x + 10/3".

The quotation for division of 7/4 that is 1 3/4 divided by 3 will be 7/12 by the rule of division that is a/b÷c/d=a/b*d/c.

A number is divided in division, which is a straightforward operation. The simplest way to conceptualize it is as a set of objects being distributed among a set of individuals, as in the example given above. A division is the division of a given sum into equal parts. For instance, we could split a group of 20 people into four groups of 5, five groups of 4, and so on. Multiplication is the opposite of division. If 3 groups of 4 add up to 12, then 12 divided into 3 groups of equal size results in 4 in each group. To determine how many equal groups are created or how many people are in each group, division is the primary objective.

Here,

1 3/4=7/4

7/4÷3/1,

a/b÷c/d=a/b*d/c

7/4*1/3=7/12

According to the division rule a/b÷c/d=a/b*d/c, the quotation for 7/4, which is 1 3/4 divided by 3, will be 7/12.

Based on an exponential model of the data, the predicted temperature of the water at 7 minutes is 39.7 °C using desmos graphing calculator.

Similar to how you discovered linear and quadratic models in prior chapters, exponential models can be found by fitting data to them. As you may already be aware, exponential functions take the form y = abx, where an is the value of y at x = 0 and b is the growth factor over each unit of time. Based on an equation like this one, the exponential model represents the degradation failure process: Y = deterioration; T = time; A and B = parameters to be calculated using the regression approach based on historical data. An expansion within a population that happens at the same pace across time is represented by the function of exponential growth. It is reasonable to suppose that data grows exponentially as populations double or triple in size.

Graph all the points on a graph. Then from the graph, we can find that at 7 minutes the temperature is 39.7°C.

According to the question,

We have the following information:

Matteo buys a basil plant that is 22 cm tall and grows 1/2 a centimeter every day.

Now, we have the following arithmetic progression with common difference, denoted by d:

22, 22.5, 23, 23.5, ...

Formula used to find the nth term:

an = a+(n-1)d where a is the first term

A) 22+(d-1)0.5 = 30

B) The plant still have to grow 8 cm because the difference between 30 and 22 is 8 cm.

C) Value of d:

22+(d-1)0.5 = 30

22+0.5d-0.5 = 30

21.5+0.5d = 30

0.5d = 30-21.5

0.5d = 8.5

d = 8.5/0.5

d = 17

The value of g in the 20 sided regular polygon is 54.

If all the polygon sides and interior angles are equal, then they are known as regular polygons.

The polygon given is a 20 sided regular polygon and the measure of each angle is 3g degrees.

Therefore, let's find g.

The sum of interior angles of a 20 sided polygon is as follows:

180(n - 2) = 180(20 - 2) = 180(18) = 3240

Therefore,

each angle = 3240 / 20 = 162

Step-by-step explanation:

The reason why I say this problem has no solution is due to the fact that it says only one person may go on Saturday yet some fraction of the people between the numbers 1 - 14 can go. We have no idea what this fraction is, leading to a paradox of multiple equations and guesses desperately trying to figure out the number. Thus, the problem has no solution.

The total amount accrued, principal plus interest, with compound interest on a principal of $12,000.00 at a rate of 14% per year compounded 12 times per year over 5 years is $24,067.32.The amount of the initial loan, or principal, is multiplied by one plus the annual interest rate raised to the number of compound periods minus one to determine compound interest.

To begin, change R from a percentage to a decimal, using the formula:

r = R/100 r = 14/100

r = 0.14 rate per year;

Next, find A by solving

A = P(1 + r/n)nt A = 12,000.00(1 + 0.14/12)(12). (5)

A = 12,000.00(1 + 0.011666666666667)(60) (60)

A = $24,067.32

Summary: The total amount accrued, principal plus interest, with compound interest on a principal of $12,000.00 at a rate of 14% per year compounded 12 times per year over 5 years is $24,067.32.

The amount of the initial loan, or principal, is multiplied by one plus the annual interest rate raised to the number of compound periods minus one to determine compound interest. You will then be left with the loan balance plus compound interest.

The dimension of pen that maximize the area is 150 ft by 150 ft.

What is the dimension of a area?

In mathematics, a dimension is the length or width of an area, region, or space in one direction. It is just the measurement of an object's length, width, and height.

Given the perimeter of the rectangular is 600 ft.

Assume that the length of the rectangular be l and the breadth be b.

The perimeter of the rectangular is 2(l+b).

According the question:

2(l+b) = 600

Divide both sides by 2:

(l+b) = 300

l = 300 - b

The area of rectangular is A = lb

Substitute the value of l in the above equation:

A = (300 - b) b

A = 300b - b^2

The maximum value of a quadratic polynomial Ax^2+BX+C is at x = - B/(2A).

Compare Ax^2+BX+C  with 300b - b^2:

A = -1 and B = 300.

Putting A = -1 and B = 300 in b= - B/(2A).

b= - 300/(2×(-1))

b = 150.

Putting b =150 in l = 300 - b

l = 300 - 150

l = 150
