What is Linear Equation in Two Variable?

A linear equation in two variables is one that is stated in the form ax + by + c = 0, where a, b, and c are real integers and the coefficients of x and y, i.e. a and b, are not equal to zero.

Solution:

Let, Number of People who kows the Code be x

Number of Peoplee who do not know the Code be y

According to the Question:

x + y = 7338 ----------(i)

2x + 5y = 17487 ----------(ii)

Multiplying Equation (i) by 2

2x + 2y = 14676 ---------(iii)

Substracting Equation (iii) from Equation (ii)

3y = 2811

y = 937

This means x = 6401

Answer:

Explanation:

Here, we want to compare values

The operator we put in the box will be dependent on the relationship between the two numbers

a) Here, we know that 1.1 is greater than 1.09, thus the operator between this too will be the less-than operator

b) Here, we want to compare a fraction and a decimal;

To make it easy, we turn them into the same form. For example, in this case, we can make the fraction, decimal and that means it will be greater than the original decimal

Thus, we use the greater than operator as shown below:

c) For negative numbers, the lower ones are usually the ones with a higher value

Take for example. we know that -2 is less than -1

Thus, in this case, we use the greater than operator as shown below:

d) This is a similar one to the last question

From (b) above, we know that 8/7 is greater, but since we are considering their negative equivalents, we are going to use the less-than operator as follows:

The velocity vector is v(t) = \(2tj + 24t^2k\) and the position vector is \(r(t) = tj + (12t^2 - 1)k.\)

The acceleration vector a(t) is given as \(2i + 6tj + 12t^2k.\) The initial velocity vector v(0) is given as i and the initial position vector r(0) is given as j - k. To find the velocity vector, we must integrate the acceleration vector with respect to time. This gives us the velocity vector \(v(t) = 2tj + 24t^2k.\)To find the position vector, we must integrate the velocity vector with respect to time. This gives us the position vector \(r(t) = tj + (12t^2 - 1)k.\) Therefore, the velocity vector and position vector of the particle are \(v(t) = 2tj + 24t^2k\)and \(r(t) = tj + (12t^2 - 1)k\) respectively.

Answer:

No

Step-by-step explanation:

No, y = 2x^3 + 5 is not a linear function. A linear function is a function that can be written in the form y = mx + b, where m and b are constants and x is the independent variable.

In the function y = 2x^3 + 5, we have a cubic term (x^3), which means that the function is not linear. The graph of a cubic function will have a curved shape, unlike a linear function, which will always be a straight line.

17.32 meters

Step-by-step explanation:

Let’s call the height of the tower H. The distance from the point to the base of the tower is 10 m. The angle of elevation from the point to the top of the tower is 60 degrees.

Using trigonometry, we can calculate that:

tan (60) = H / 10

H = 10 * tan (60)

H = 10 * √3

H = 17.32 m

Therefore, the height of the tower is 17.32 meters.

The probability that in a given game the lions will score less than 3 goals is 0.80.

The probability distribution for the number of goals the lions soccer team makes per game is given below:

number of goals probability 0 0.30 1 0.35 2 0.15 3 0.10 4 0.10. The probability that in a given game the lions will score less than 3 goals is 0.80.

To find the probability that in a given game the lions will score less than 3 goals, we need to add up the probabilities for scoring 0, 1, or 2 goals.

P(Less than 3 goals) = P(0 goals) + P(1 goal) + P(2 goals)

We have the following probabilities:

P(0 goals) = 0.30

P(1 goal) = 0.35

P(2 goals) = 0.15

Therefore,

P(Less than 3 goals) = P(0 goals) + P(1 goal) + P(2 goals)

                                 = 0.30 + 0.35 + 0.15

                                 = 0.80

Answer:

Step-by-step explanation:

If the angle of elevation at point B is 7.4°, then the sun is 90° -7.4° = 82.6° from the vertical. This is the measure of the central angle between the two points. That represents a fraction of a circle that is ...

  82.6°/360° = 413/1800 ≈ 0.229444...(repeating)

The relation between the given distance and the circumference is ...

  0.294444C = 2105 mi

  C = 2105 mi/0.294444 ≈ 9174 mi

The radius of the spherical planet is this divided by 2π:

  r = C/(2π) = 9174 mi/(2π) ≈ 1460 mi

The radius of the planet is about 1460 miles; the circumference is about 9174 miles.

When a customer pays interest to borrow money from a bank, for example, interest is referred to as a payment from the borrower in the finance industry.

The customer would pay an amount that is greater than the amount they borrowed due to interest.

The principal is the sum of money that was first invested or lent and upon which interest is based.

We refer to the process of calculating fresh interest based on the new principal (which is the old principal plus interest) at the conclusion of the subsequent payment period as compound interest when we add interest to interest.

So, compound interest is interest that is paid on both the principal and interest that has already been generated.

We may calculate compound interest using the following straightforward formula:

That has to be clarified in order for us to address the issue at hand:

17400 invested at a 2.5% annual compounded rate for an 8-year period.

In a polynomial, a term will generally be a constant, or a constant multiplied by a variable or some product of variables.

In other kinds of expressions, we often describe explicitly what we're considering to be a term. For example, we might say that in 3√(x+2), the term (x+2) must be non-negative. If this radical expression were part of something larger, we might describe all of it as being a term.

Answer

2617.

Step-by-step explanation

To estimate the number of people that can fit into a circular arena with a diameter of 100 yards, we first need to find the area of the arena. To do this, we can use the formula for the area of a circle, which is equal to pi times the radius squared. Since the diameter of the arena is 100 yards, the radius would be half of that, or 50 yards. Plugging this value into the formula for the area of a circle, we get:

Area = pi * 50^2

Since pi is approximately equal to 3.14, we can plug this value into the equation to get:

Area = 3.14 * 50^2

This simplifies to:

Area = 3.14 * 2500

Which gives us an area of approximately 7850 square yards.

Since one person requires a personal space of 3 square feet, we can divide the total area of the arena by 3 to find the number of people that can fit in the arena. This gives us:

7850 square yards / 3 square feet/person = 2616.666... people

Rounded to the nearest whole number, this means that approximately 2617 people could fit in the circular arena with a diameter of 100 yards.
