1.6% change in the level of oxygen for each 1000 feet of level change.

let the oxygen level at ground be x

so the oxygen level at 2000 feet above sea level is 0.18x

ans the oxygen level at 4500 feet above sea level is 0.14x

so total change = 0.04x for 2500 feet

so per feet height change  = 0.04x/2500

for every 1000 feet of elevation change the percentage change is given by  = (0.04*1000)/2500

=> 0.016x

so percentage change = 0.016x/x * 100

=> 1.6 %

so for every 1000 feet 1.6% change in the oxygen level is observed at that elevation.

For every 1000 feet of elevation variation, the oxygen level changes by 1.6%.

In most cases, elevation is used to describe locations on the surface of the Earth, whereas altitude or geopotential height is used to describe locations above the surface, such as those of flying airplanes or orbiting satellites, and depth is used to describe locations below the surface.

Let the ground's oxygen level be x.

the oxygen concentration is 0.18x at 2000 feet above sea level.

ans the oxygen concentration is 0.14x at 4500 feet above sea level.

hence the overall change for 2500 feet is 0.04x.

as a result, per foot height change, 0.04x/2500

The formula is (0.04*1000)/2500, where 1000 feet of elevation change equals 1000 feet of change in percentage.

=> 0.016x

Consequently, % change = 0.016x/x * 100.

=> 1.6 %

Therefore, at that elevation, there is a 1.6% variation in the oxygen level for every 1000 feet.

The point at which the triangle's three interior angle bisectors intersect appears to be the incenter.

The incenter of a triangle seems to be the point at which the triangle's three interior angle bisectors intersect. This point is equidistant from the triangle's sides.

∠ARU angle = 40°

AU length = 20°

∠QPA = 35°

A diagram is included here.

AR is the angle bisector of angle URK.

As a result, ∠ARU = ∠ARK = 40°.

Because the incenter point is equidistant from the triangle's sides.

As a result, AT = AU = AK = 20.

Because PA is the angle bisector of angle QPU.

As a result, ∠QPA = ∠UPA.

3x + 2 = 4x - 9

4x - 3x = 9 + 2

x = 11

Changing the value of x in the angle 3x + 2

We obtain ∠QPA = 3(11) + 2 = 35°.

The practical range of the function is between $100 and $625.

This can be calculated using the formula y=10x, where x is the number of subscriptions sold each week and y is the amount of money earned. To calculate the amount of money earned for selling t subscriptions each week, we can use the formula y = 10t. This can be interpreted as saying the amount of money (y) is equal to 10 times the number of subscriptions sold (t). For example, if Clarence sells 15 subscriptions each week, then we can calculate the amount of money he earns by plugging in t = 15. y = 10(15) = 150. This means Clarence earns $150 each week by selling 15 subscriptions. For example, if Clarence sells 10 subscriptions each week, he would earn $100 (10 x 10 = 100). If he sells 25 subscriptions each week, he would earn $625 (25 x 25 = 625). The practical range of the function is therefore $100 to $625.

The solution set for the given graph is (2,1). The solution has been obtained using linear equations.

What is a linear equation?

It is a linear equation that has the greatest degree of one. In a linear equation with an exponent greater than one, this indicates that there are no variables. A straight line is produced on the graph by this equation.

We are given two lines on the graph

The points of the red line are (3,0) and (0,3)

So, the equation of the line comes out to be

y=−x+3      ...(1)

The points of the blue line are (3,2) and (-1,-2)

So, the equation of the line comes out to be

y=x−1     ...(2)

To find the solution set, we need to solve the equations

Substituting (1) in (2), we get,

⇒−x+3 = x−1

⇒−2x = -4

⇒x = 2

So, y = 1

Hence, the solution set for the given graph is (2,1).

The two solutions of the system of equations are (4, -1) and (-1, 4).

Here we want to solve the system of equations below:

x + y = 3

x^2 + y^2 = 17

We can isolate x on the first equation to get:

x = 3 - y

And replace that in the other equation to get:

(3 - y)^2 + y^2 = 17

9 - 6y  + y^2 + y^2 = 17

2y^2 - 6y + 9 - 17 = 0

2y^2 - 6y - 8 = 0

y^2 - 3y -4 = 0

Using the quadratic formula we will get the solutions:

[tex]y = \frac{3 \pm \sqrt{(-3)^2 - 4*1*(-4)} }{2} \\\\y = \frac{3 \pm5 }{2}[/tex]

So the two solutions are:

y = (3 + 5)/2 = 4

y = (3 - 5)/2 = -1

The correspondent values of x are given by evaluating the line.

x + 4 = 3

x = 3 - 4 = -1

So we have the point (-1, 4)

x - 1 = 3

x = 3 + 1

x = 4

So we have the point (4, -1)

Answer: The expected probability that the coin will land with the tails side facing up the next time it is tossed can be calculated by taking the ratio of the number of times the tails side came up to the total number of tosses. In this case, the coin landed tails 12 times out of 30 tosses. So the probability of tails is:

12/30 = 0.4

Therefore, the expected probability that the coin will land with the tails side facing up the next time it is tossed is 0.4 or 40%.

It's important to notice that this probability is based on the assumption that the coin is fair, meaning it has an equal chance of landing heads or tails each time it is tossed.

In mathematics, division is the process of breaking a number into equal parts and determining how many equal parts can be made. For example, dividing 15 by 3 divides 15 into three equal groups of five.

The symbol '÷' or '/' is used to represent division.

Any positive number with no decimal or fractional part is referred to as a whole number. Because these criteria are met, the numbers 1,2,15,500, and 1546 are all whole numbers.

Children will practise dividing whole numbers as they begin to learn their multiplication tables. This is due to the fact that all of the numbers in the times tables are whole numbers!

They will also learn that division is the inverse operation to multiplication, which simply means that division and multiplication perform opposite functions in mathematics.

The correct statement is C. The angular acceleration of each of the wheels is 4 (rad/s)^2.

The car has a uniform acceleration from 10 m/s to 20 m/s, so the average speed is (10 m/s + 20 m/s) / 2 = 15 m/s. The time it takes to travel the 150-metre-long track at this average speed can be found using the equation:

distance = speed x time

time = distance / speed = 150 m / 15 m/s = 10 s

The linear acceleration of a point on each wheel can be found using the equation:

a = (vf - vi) / t = (20 m/s - 10 m/s) / 10 s = 1 m/s^2

The angular acceleration of each wheel can be found using the equation:

alpha = a / r = 1 m/s^2 / 0.25 m = 4 rad/s^2

The initial angular velocity of each wheel is not given in the problem, so statement D is not necessarily true.

In this problem we find the definition of cubic equation as a product of a linear equation and a quadratic equation, the latter one has four unknown real coefficients, whose values can be found by expanding the product and comparing coefficients. First, write the entire equation:

4 · x³ + 12 · x² + 3 · x - 5 = (2 · x - 1) · (p · x² + q · x + r)

Second, expand the expression:

4 · x³ + 12 · x² + 3 · x - 5 = (2 · x - 1) · p · x² + (2 · x - 1) · q · x + (2 · x - 1) · r

4 · x³ + 12 · x² + 3 · x - 5 = 2 · p · x³ - p · x² + 2 · q · x² - q · x + 2 · r · x - r

4 · x³ + 12 · x² + 3 · x - 5 = 2 · p · x³ + (- p + 2 · q) · x² + (- q + 2 · r) · x - r

Third, find the values of p, q, r by comparison:

2 · p = 4

- p + 2 · q = 12

- q + 2 · r = 3

- r = - 5

Then:

p = 2, r = 5

q = - (3 - 2 · r)

q = - (3 - 2 · 5)

q = - (- 7)

q = 7

- 2 + 2 · 7 = 12

We determine the value of x by solving the expression.

In the question;

(2.1 - 0.7) + (x + 3.4) is equivalent to -3.95 + 2.7

Finding the value of the variable is part of solving an algebraic expression. We must perform certain algebraic operations to determine the value of one of the variables in the linear equations before we can substitute that value to determine the value of another variable.

We can write it as

(2.1 - 0.7) + (x + 3.4) = -3.95 + 2.7

Simplify the expression

1.4 + x + 3.4 = -1.25

x + 4.8 = -1.25

Subtract 4.8 on both side, we get

x = -6.05
