A race car on a 150-metre-long track has a uniform acceleration from 10 m/s to 20 m/s travelling the full distance of the track. Each wheel of the car has a 250-millimetre radius. Which statement must be true?

A. The time the car is accelerating is 5 seconds.
B. The linear acceleration of a point on each of the wheels is
4 (m/s)^2.
C. The angular acceleration of each of the wheels is 4 (rad/s)^2.
D. The initial angular velocity of each of the wheels is 20 rad/s.

Answers

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.

a climber measures the oxygen content of the air at 2,000 feet above sea level at 18%. the climber measures it again at 4,500 feet, this time at 14%. by how much does the oxygen content of the air change for every 1,000 feet of elevation?\

Answers

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

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 answer to the above graphing problem is that we can easily infer that the graph will initially begin to decline before quickly increasing.

Graph: What is it?

A graph is a mathematical structure that joins a number of points together to represent a certain function. It establishes a pairwise link between the things. The vertices of a network, also known as its nodes, are the edges that link them (lines).

The graph's objective is to graphically portray numerical data for rapid, easy, and clear comprehension. Consequently, graphs are visual representations of data. Data can also be presented as a table, despite the fact that a graphical depiction is simpler to grasp.

Here,

If she first moves in the direction of the petrol station, the graph will be lowering.

As she fills her tank at the gas station, the graph moves upward.

As she approaches the market, the graph will eventually start to decline.

In light of the information,

We can easily deduce that the graph will start out falling, quickly climb, and then keep falling until we reach our target.

As a result, we can quickly deduce that the graph will rapidly increase after initially dropping as the answer to the given graph problem.

Clarence sells yearly subscriptions to a particular magazine. he sells at least 10 and no more than 25 subscriptions each week. the function represents the amount of money earned for selling t subscriptions each week. what is the practical range of the function?

Answers

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.

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.

∠ARU angle = 40°

AU length = 20°

∠QPA = 35°

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

Answers

The total number of boys enrolled in the course is 170.

Here are 374 children, are there are 5 boys to every 6 girls.

If the ratio of boys to girls is 5 to 6, then 5 out of every 11 students are boys and 6 out of every 11 students are girls.

Set up a proportion for the boys, where b = the total number of boys.

5/11 = b/374

11b = 1870

b = 1870/11

b = 170

There are 170 boys.

The total number of student is 374, so the number of girls, is 374 -b.

There are 374-170= 204 girls.

Finding a proportionality constant would be another algebraic solution to this issue. The total number indicated by the ratio is 5 + 6 or 11, which is equal to the total number of children when multiplied by the proportionality constant.

Let x = the proportionality constant

Parallelograms lack right angles, not all of them can be rectangles. There must be right angles for a parallelogram to be considered a rectangle.

Not every parallelogram has a rectangular component. A rhombus is not a square since its angles are not 90 degrees, yet a square is a rhombus. In a parallelogram, the opposing angles are equal (or congruent) The complementary angles to each other are consecutive angles (that means they add up to 180 degrees).A parallelogram's diagonals cut each other in half.

How to find the values of missing coefficients in a cubic equation

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

- 2 + 14 = 12

12 = 12

The values of real coefficients are (p, q, r) = (2, 7, 5).

A zero correlation indicates that there is no relationship between 2 variables.

What is correlation?

The relationship between variables is described by correlation. It can be either strong or weak, as well as positive or negative. Correlation is a statistical measure that expresses how closely two variables are related linearly (meaning they change together at a constant rate). It's a common tool for describing simple relationships without stating a cause and effect relationship. A correlational study can yield three outcomes: a positive correlation, a negative correlation, or no correlation. A positive correlation is a two-variable relationship in which both variables move in the same direction.

grew graph B for graph A

A coin has heads on one side and tails on the other side. The coin is tossed 30 times to see if it lands heads or tails. The table below summarizes the results. Heads Tails 18 12 Based on these results, enter the expected probability that the coin will land with the tails side facing up the next time it is tossed. Enter your answer as a decimal.​

Answers

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.

knowing that a centimeter is 10 times larger than a millimeter, how much more volume is a cubic centimeter (cm3) than a cubic millimeter (mm3)?

Answers

A cubic centimeter is 1000 times larger than a cubic millimeter because 1 centimeter equals 10 millimeters, and a volume is calculated by multiplying the length.

Width and height, so 1cm x 1cm x 1cm = 1cm3 and 0.1mm x 0.1mm x 0.1mm = 0.001mm3. A measure of volume in the metric system. One thousand boxy centimeters equal one liter. Also called cc, milliliter, and mL.  

A cubic centimeter ( symbol cm ³ or cc)(U.S. spelling boxy centimeter) is a generally used unit of volume extending the deduced SI-unit boxy meter. It corresponds to the volume of a  cell measuring 1 cm × 1 cm × 1 cm.

A cubic centimetre is 1000 times greater than a cubic millimetre.

A volume is derived by multiplying the length, width and height.

As we know.

1 centimetre equals 10 millimetres.

Therefore 0.1mm x 0.1mm x 0.1mm = 0.001mm^3

And 1cm x 1cm x 1cm = 1cm^3.

A volumetric measurement using the metric system.

One litre is equivalent to one thousand boxy centimetres. Also known as cc, mL, and millilitre.

the 2 digit number which becomes 5/6th of itself when its digits reversed

Answers

The 2 digit number is 45 which becomes 5/6th of itself when its digits reversed.

What is number?

A number is a numerical unit of measurement and labelling in mathematics. The natural numbers 1, 2, 3, 4, and so on are the first examples.

Let the two digits of the number are x and y.

So, the number is 10x + y.

When its digits reversed: the number becomes: (10y + x)

According to the question:

(10y + x) = 5/6 (10x + y)

60y + 6x = 50x + 5y

60y - 5y = 50x - 6x

55x = 44y

x/y = 44/55

x/y = 4/5

Hence, the two digits of the number are 4 and 5 and the number is 45.
