In 1787 the French scientist Jacques Charles observed that when he plotted the graph of volume of a fixed amount of air versus the temperature of the air, the points lay along a straight line. Therefore, he concluded that volume of a gas varies linearly with temperature. Suppose that at 27º C a certain amount of air occupies a volume of 500 cm3. When it is warmed to 90º C, it occupies 605 cm3.
a) Write the particular equation in slope-intercept form expressing volume in terms of temperature.
b) Predict the volume at 60º C.
c) The process of predicting a value between two data points is called “interpolation”.
What is the origin of the word?
d) Predict the volume at 300º C.
e) The process of predicting a value beyond any given data points is called
“extrapolation”. What is the origin of this word?
f) Extrapolate your mathematical model back to the point where the volume is zero.
That is, find the temperature-intercept.
g) What is the special name given to the temperature in part f)?

Answers

Answer 1

The relationship between the volume, V, and temperature, T, of a given mass of gas, found by the French scientist Jacques Charles, gives;

a) The slope–intercept form of the equation that expresses the volume in terms of the temperature of the gas is; [tex] \displaystyle{ V = 1. \bar 6 \cdot T + 455}[/tex]

b) The volume at 60 °C is 555 cm³

c) Interpolation originates from the verb interpolare

d) The temperature at 300 °Cis 955 cm³

e) Extrapolation originates from 'extra' (meaning outside) and the shortened form of Interpolation

f) The temperature–intercept is -273 °C

g) The special name is the absolute zero temperature

What is Charles law for gases?

Charles law states that the volume of a given mass of gas is directly proportional to its temperature given in Kelvin.

Mathematically, Charles Law states that; V = K•T

Where;

V = The volume of the gas

T = The gas temperature

K = The proportionality constant

The volume occupied by the gas at 27 °C = 500 cm³

The volume occupied at 90 °C = 605 cm³

a) To write the equation in slope–intercept form, we have;

[tex] \displaystyle{ Slope = \frac{605 - 500}{90 - 27} =1. \bar{6} =1. \bar{6}}[/tex]

The equation of the line in point and slope form is therefore;

Point–slope form; [tex] \displaystyle{ V - 500 = 1. \bar{6} \times (T - 27) }[/tex]

[tex] \displaystyle{ V = 1. \bar{6} \cdot T -45 + 500 = 1. \bar{6} \cdot T + 455}[/tex]

The equation in slope–intercept form of expressing the volume, V, in terms of the temperature, T, is therefore;

Volume equation; [tex] \displaystyle{ V = 1. \bar{6} \cdot T + 455}[/tex]

b) The volume at 60 °C is given from the equation that gives the volume, V, in terms of time, T as follows;

[tex] \displaystyle{ V(T) = 1. \bar{6} \cdot T + 455}[/tex]

When T = 60 °C

[tex] \displaystyle{ V(60) = 1. \bar{6} \times 60 + 455=555}[/tex]

The volume occupied by the gas at 60 °C is 555 cm³

c) The word interpolate originated from the Latin word interpolare which means to alter or refurbish

d) The volume occupied by the gas at 300 °C is given by the function for the volume, V, in terms of temperature, T, equation as follows;

When T = 300 °C

[tex] \displaystyle{ V(300) = 1. \bar{6} \times 300 + 455 = 955}[/tex]

The volume of the gas at 300 °C is 955 cm³

e) Extrapolation originate from the word 'extra' which refers to the outside of an area. Extra is combined with a short form of interpolate to give the word, extrapolation

f) When the volume is zero, the volume function equation can be used to find the temperature as follows;

Volume function; [tex] \displaystyle{ V = 1. \bar{6} \cdot T + 455}[/tex]

When V = 0

[tex] \displaystyle{ V = 0 =1. \bar{6} \cdot T + 455}[/tex]

[tex] \displaystyle{ -455 = 1. \bar{6} \cdot T }[/tex]

[tex] \displaystyle{T = \frac{3 \times (-455)}{5}= -273 }[/tex]

The temperature at which the volume of the gas is zero is -273 °C

g) The special name given to -273 °C of the gas is the absolute zero temperature.

general rule!

Sum of three angles in a triangle is always equal to 180°

1) let unknown angle be x
The other two angles are 29° , 105°
As per rule,
=> 29 + 105 + x = 180°
=> 134 + x = 180°
=> x = 180-134 = 46° (unknown angle)

2)To find measure of Angle 1 , let us find the measure of Angle 2

=> Angle 2 + 78 + 55 = 180

=> Angle 2 = 180-133 = 47°(answer for third question)

Getting back to second equation,

We find angles are supplemental or on straight line ,

Angle 1 + Angle 2 = 180°

=> Angle 1 = 180 - 47 = 133°

4) The measure of of exterior angle is always equal to the measure of adjacent interior angles because exterior angle is supplement to adjacent angle.

Answer:

1) 180°-105°-29°

=46° (angles in ∆)

2) 180-78-55

180-78-55 =47° (angle ²)

then angle ¹ is

180-78-47

We have a vertical and a horizontal lines, the equations are:

Line A: x = -5  (vertical one)

Line B: y = -5  (horizontal one)

How to find the equations of the two lines?

Remember that the general linear equation in the slope-intercept form is:

y = a*x + b

Where a is the slope and b is the y-intercept.

If the line passes through the points (x₁, y₁) and (x₂, y₂) then the slope is:

a = (y₂ - y₁)/(x₂ - x₁)

Now, line A passes through  (–5, –2), (–5, 7), then the slope is:

a = (7 + 2)/(-5 + 5) = 9/0

Notice that if we divide by zero, the slope tends to infinity, so we have a vertical line.

In this case, the line A will be x = -5.

Now line B passes through points: (7, –5), (–2, –5)

Then the slope is:

a = (-5 + 5)/(-2 - 7) = 0/-9 = 0

Then the line is:

y = 0*x + b

And passes through (7, –5), then:

-5 = 0*7 + b

-5 = b

What is addition?

Combining things and counting them as one big group is done through addition. In math, addition is the process of adding two or more integers together. Addends are the numbers that are added, while the total refers to the outcome of the operation. The sum is the entire value, and the addends are the integers that are being added. The mathematical operation of addition is the process of adding two or more numbers together to determine the total, or sum.

Given that,

The position function s(t) = 2.3t² + 225.

The velocity of the ball after 5 seconds is

s(t) = 2.3t² + 225.

t= 5

s(5) = 2.3(5)² + 225.

s(5) = 2.3(25) + 225.

Find the mean of the data set first, then use that value to calculate the mean absolute deviation of the data. Divide the total number of data values by the sum of the individual data values. Assess the magnitude of the absolute difference between each data point and and the mean.

The measured data is

x = [10.56, 9.52, 9.73, 9.80, 9.78, 10.91]

There are 6 measurements.

Calculate the mean.

m = (10.56+9.52+9.73+9.80+9.78+10.91)/6 = 10.05

Calculate deviations from the mean.

y = |x - m|

  = [0.51, 0.53, 0.32, 0.25, 0.27, 0.86]

The greatest deviation from mean is d = 0.86.

Calculate the average absolute deviation.

(0.51+0.53+0.32+0.25+0.27+0.86)/6 = 0.4567

The answer is: d = 0.86

last week, 3/4 of the students in Mr. Zanker's class went on a field trip. 5/8 of the students in Mr. Haynes's went. What is the average fraction of students in the two classes who went on the field trip?

Answers

The average fraction of students in  Mr. Zanker's class and  Mr. Haynes  who went on the field trip is 11/8.

How can the fraction be calculated?

From the question, the fraction of the students in Mr. Zanker's class that attended the field trip is  3/4.

The  fraction of the students in  Mr. Haynes class that attended the field trip is 5/8 .

Then the we can calculate the average fraction of student in the class of the two teacher is

= (3/4 + 5/8) = 11/8.

Therefore, the average fraction of the number of the student can be calculated as 11/8.

The numerical value of x in the two congruent alternate exterior angles is 20.

What is the numerical value of x?

Alternate exterior angle theorem states that "if a transversal intersects two parallel lines, the alternate angle s formed are congruent.

From the diagram, the two angles forms an alternate exterior angle , the two angles are congruent.

( 5x - 8 ) = ( 3x + 32 )

Solve for x

5x - 8 = 3x + 32

Collect like terms by moving all terms containing variable x to left and the constant terms to the right side of the equation.

5x - 8 = 3x + 32

5x - 3x = 32 + 8

2x = 40

Divide both sides by 2

2x/2 = 40/2

x = 40/2

x = 20

Therefore, the numerical value of x is 20.

The probability of happening of the events either B or C is [tex]\frac{2}{3}[/tex]

What is Addition Rule in Probability?

The probability that event A or event B happens is equal to the

probability that A happens plus the probability that B happens minus the probability that both happen. If events A and B are mutually exclusive, then the probability that event A or B happens is simply the sum of the probabilities. Given that

A = rolling a number greater than four

B = rolling an even number

C = rolling a multiple of 3

So,

P(A) = [tex]\frac{2}{6} =\frac{1}{3}[/tex]

P(B)=[tex]\frac{3}{6} =\frac{1}{2}[/tex]

P(C) = [tex]\frac{2}{6} =\frac{1}{3}[/tex]

Now, We have to find the probability of occurence of either event B or C

So, We know that

P(B or C ) = P(B) + P(C) + P(B or C)

P(B or C )= [tex]\frac{3}{6} +\frac{2}{6} -\frac{1}{6} =\frac{4}{6}[/tex]

P(BorC)= [tex]\frac{2}{3}[/tex]

Therefore, the probability of occurence of either event B or C is [tex]\frac{2}{3}[/tex].
