Answer: a. This line's slope-intercept equation: y=-9.7x+417.1
b. 31 minutes after the experiment started, there would be 116.4 grams of gas left.
c. If a linear model continues to be accurate,43 minutes since the experiment started, all gas in the container will be gone.
Step-by-step explanation:
Linear equation: y=mx+c (slope-intercept equation)
, where m= rate of change in y with respect to change in x , c= Initial value.
Let y= Mass of remaining gas after x minutes.
m= -9.7 (given)
At x= 8, y=339.5
Thus,
[tex]339.5=(-9.7)(8)+c\\\\\Rightarrow\ 339.5=-77.6+c\\\\\Rightarrow\ c= 339.5+77.6=417.1[/tex]
a. This line's slope-intercept equation: y=-9.7x+417.1
b. At x= 31 minutes
y=-9.7(31)+417.1
⇒ y=-300.7+417.1
⇒ y=116.4
31 minutes after the experiment started, there would be 116.4 grams of gas left.
c. Put y=0, we get
[tex]0=-9.7x+417.1\\\\ x=\dfrac{417.1}{9.7}\\\\ x=43[/tex]
If a linear model continues to be accurate,43 minutes since the experiment started, all gas in the container will be gone.
A man crosses a distance of 48 meters while going round a quadrilateral field twice. What will be the cost of fencing the field at the cost $1.75 per meter?
A man crosses a distance of 48 meters while going round a quadrilateral field twice. For 24 m cost of fencing the field is $42.
What is perimeter?The circumference of an object is known as its perimeter. For instance, your home has a yard that is enclosed. The length of the fence is the perimeter. The length of your fence is 200 feet if the yard is 50 feet by 50 feet. P = length + breadth + length + breadth is the equation for a rectangle's perimeter. Add the lengths of the four corners of a rectangle to find its perimeter. You can quickly locate all four sides if you only know the width and height (two sides are each equal to the height and the other two sides are equal to the width). Add the outcomes after dividing the height and breadth by two.Perimeter of the field is the total lengths of its boundary = 48/2 m = 24 m
For 1 m, cost of fencing the field = $1.75
Therefore, for 24 m cost of fencing the field = $(1.75 × 24) = $42

The population of a town increased from 3600 in 2007 to 4700 in 2011. Find the absolute and relative (percent) increase.
1100 Absolute is a 30.55% increment relative percent
To find an Increment percentage in population we need the Number of increases in population.
4700- 3600 = 1100
That is absolutely increased number.
For relative increment, we need to find the Percentage -
Increment Percentage = (value / total value) * 100%so the population in 2007 was 3600
so percentage = 1100/3600*100
=> 30.55%
SO Relative increase = 30.55%

since they are complementary their angles should add up to 90.
18+(8x-28)=90
you solve from there
add common values
8x-10+90
add 10 to both sides
8x=100
divide by 8
x=12.5
The answer is:
x = 12.5Work/explanation:
Since we're given both angles, we can set up an equation and find x.
The sum of two complementary angles is 90°.
Now, set up the equation:
[tex]\sf{8x-28+18=90}[/tex]
[tex]\sf{8x-10=90}[/tex]
Add 10 on each side
[tex]\sf{8x=100}[/tex]
Divide each side by 8

Answer:
5509 yes votes
Step-by-step explanation:
We will start by adding together our ratio, so we know how many voters there were in a total ratio, so we can divide our total number of people by it, and then multiply it by the number of people who said yes (7 people).
Our ratio was 7:4, so adding those two numbers together gives us 11. Then, dividing 8657 by 11 gives us:
8657 / 11 = 787
Now, we will multiply 787 by 7, since that was the number of people who said yes:
787 * 7 = 5509
So, there were 5509 yes votes.

Since the points on this graph represent a relationship between x- and y-values, a statement about the relationship which is true include the following: A, it cannot be proportional because the straight line through the points does not go through the origin.
What is a proportional relationship?In Mathematics, the graph of any proportional relationship between two (2) variables is always characterized by a straight line with the data points starting from the origin (0, 0) and passes through other unique data points on the cartesian coordinate.
By critically observing the graph which shows a relationship between the x-values and y-values, we can logically deduce that it does not start from the origin (0, 0) and as such, it does not represent a proportional relationship.

Answer:
-35/24
Step-by-step explanation:
5/8 - (3 - 1/4) + 2/3 =
Distribute the negative sign to 3 and -1/4. When a negative sign is distributed to a negative number, that number becomes positive:
- (3 - 1/4) ==> -3 + 1/4
5/8 - 3 + 1/4 + 2/3 =
Now multiply the equation by 24/24 = 1. Multiplying anything by 1 results in the same equation. For example, 8 * 1 = 8.
Also multiply the equation by 24/24 because 24 is the LCM (Least Common Multiple) of the denominators 8, 4, and 3: 8*3=24. 6*4=24.
(5/8 - 3 + 1/4 + 2/3) * 24/24 =
(5*24/8 - 3*24 + 1*24/4 + 2*24/3) / 24 = ==> multiply each term by 24 and

What is an expression?When used to represent a quantity or a mathematical relationship, symbols and numbers are combined to form an expression in mathematics. It may contain exponents, brackets, variables, constants, and mathematical operations like addition, subtraction, multiplication, and division.
To simplify the expression 5/8 - (3 - 1/4) + 2/3, we need to follow the order of operations (also known as PEMDAS):
First, we need to simplify the expression inside the parentheses (3 - 1/4):
3 - 1/4 = 12/4 - 1/4 = 11/4
Next, we need to subtract 11/4 from 5/8:
5/8 - 11/4 = 5/8 - 22/8 = -17/8
Finally, we need to add 2/3 to the result:
-17/8 + 2/3
To add these two fractions, we need to find a common denominator. The least common multiple of 8 and 3 is 24, so we can rewrite the fractions with a denominator of 24:
-17/8 + 2/3 = (-51/24) + (16/24) = -35/24

To compute the Laplace transform of a function, we use the integral definition , F(s) = L{f(t)} = ∫ f(t) e^(-st) dt.
What is integral definition ?
The integral definition of the Laplace transform is a mathematical method used to find the Laplace transform of a function. It is defined as,
F(s) = L{f(t)} = ∫ f(t) e^(-st) dt , Where F(s) is the Laplace transform of the function f(t), s is a complex variable known as the frequency domain variable, and t is the time domain variable.
Given the functions f(t) provided ,
f(t) = e^(-8t)sin(5t)
F(s) = L{e^(-8t)sin(5t)} = ∫ e^(-8t)sin(5t) e^(-st) dt = (5/(s+8+5i))(e^(-8-s)) - (5/(s+8-5i))(e^(-8-s))
f(t) = e^(-st)sinh(7t)
F(s) = L{e^(-st)sinh(7t)} = ∫ e^(-st)sinh(7t) e^(-st) dt = (7/(s^2+49))(e^(-s-7i)) - (7/(s^2+49))(e^(-s+7i))
f(t) = -7t cosh(5t)
F(s) = L{-7t cosh(5t)} = ∫ -7t cosh(5t) e^(-st) dt = (-7/s^2)(e^(-s-5)) - (7/s^2)(e^(-s+5))
f(t) = 9t sin(ut)
F(s) = L{9t sin(ut)} = ∫ 9t sin(ut) e^(-st) dt = (9/(s^2 + u^2))(e^(-su)) - (9/(s^2 + u^2))(e^(su))
Note that in all cases, we should check if the integral converges, and that the limits of integration are appropriate.

The area of the right triangle shown is 24 square feet. Which equations can be used to find the lengths of the legs of the triangle? Select three options. 0.5(x)(x + 2) = 24 x(x + 2) = 24 x2 + 2x – 24 = 0 x2 + 2x – 48 = 0 x2 + (x + 2)2 = 100
There are only three correct equations for the area of the right triangle which are:
0.5(x)(x + 2) = 24x² + 2x - 48 = 0x² + (x + 2)² = 100.Area of a triangleThe area of a triangle is calculated by dividing the product of the base and height of the triangle.
base of the triangle = x
height of the triangle = x + 2
area of the triangle = 1/2(x)(x + 2)
so
1/2(x)(x + 2) = 24...(1)
1/2 is also 0.5, so the equation 0.5(x)(x + 2) = 24 is correct.
by cross multiplication, equation (1) becomes;
x(x + 2) = 48
x² + 2x = 48 {expand the left hand side}
x² + 2x - 48 = 0 {subtract 48 from both sides}
so the equation x² + 2x - 48 = 0 is correct.
Considering the last equation, x² + (x + 2)² = 100
x² + x² + 4x + 4 = 100
2x² + 4x = 100 - 4 {collect like terms}
2x² + 4x = 96 {divide through by 2}
x² + 2x = 48
x² + 2x - 48 = 0
so the equation x² + (x + 2)² = 100 is equivalent to the equation (1) and so is also correct.
Therefore, the equations 0.5(x)(x + 2) = 24, x² + 2x - 48 = 0, and x² + (x + 2)² = 100 are correct and can be used to find the length of sides for the right triangle.

=> A = 120[tex](1.016)^{4t}[/tex]
The function is A = 120[tex](1.016)^{4t}[/tex]. Now years t = 6 then
=> A = A = 120[tex](1.016)^{4*6}[/tex] = 120[tex](1.016)^{24}[/tex]
=> A = $175.64
Hence the function is A = 120[tex](1.016)^{4t}[/tex] and the balance after 6 years is $175.64 .

Pedro and Bella are reading the same book for their language-arts class. On Saturday, Pedro starts the day at page 20 and reads at an average rate of 25 pages per hour. Bella starts reading at the same time, but she starts at page 60 and reads at an average rate of 18 pages per hour.
Answer: If Pedro starts reading at page 20 and reads at an average rate of 25 pages per hour, and Bella starts reading at the same time but starts at page 60 and reads at an average rate of 18 pages per hour,
We can use the formula: distance = rate x time
To find out when they will meet we need to find out when they are on the same page.
let's say t be the time in hours, Pedro will be reading t25 pages, and Bella will be reading t18 pages.
So we can write the equation: 20+t25 = 60+t18
Solving this equation we get t = 2
So, they will meet after 2 hours.
Pedro will be on page 20+225 = 70, and Bella will be on page 60+218 = 96
So they will meet at page 70 when Pedro reaches that page after 2 hours of reading, which means Bella will have read 26 pages more than Pedro on that point.

Which equation could be used to find the missing side of the triangle shown?
10 m
am
5 m
O a² +52
10²
O 5² + 10² a²
O2 (5) +2 (10) = 2a
O a² + 10² 5²
=
O a² + 10² 5² =25 + 100 =2a ,2a=125 , a=\sqrt{125} , a=11.18 m
Therefore, the missing side (a) is 11.18 m.
Calculate the missing side (a) of the triangle
We are trying to find the missing side (a) of the triangle shown in the diagram.
To do this, we will use the Pythagorean Theorem, which states that the sum of the squares of the two shorter sides of a right triangle is equal to the square of the longest side.
The two shorter sides of the triangle are 5 m and 10 m.
We will use the Pythagorean Theorem to calculate the missing side (a).
First, we need to square the lengths of the two shorter sides:
5² = 25
10² = 100
Next, we add the squares of the two shorter sides together:
25 + 100 = 125
Finally, we take the square root of the sum to find the length of the missing side:
√125 = 11.18 m
Therefore, the missing side (a) is 11.18 m.

Researchers routinely chose an alpha level of 0.05 for testing their hypotheses. What are some experiments for which you might want a lower alpha level (e.g., 0.01)? What are some situations you might accept a higher level (e.g., 0.1)?
Researchers frequently select a level of significance of 0.05. The reason for this is that if we chose a lower threshold of significance, we will have less room to reject the null hypothesis and so a higher likelihood of making a type 2 error.
On the other hand, if the degree of significance is higher, more type 1 errors are made, leading us to reject the hypothesis even though it is correct. Therefore, 0.05 is a balanced level that is neither significantly greater nor significantly smaller. The health care and nutrition-related industries are mostly included in some of the studies where we require a lower level of importance. This type of industry has a higher error rate, which causes more fatalities and negative side effects.
We can use a higher level of relevance in a variety of circumstances, such as the entertainment and marketing-related industries. The reason for this is that even if there are more potential for error, it won't harm the person; instead, it just affects the information, which we can assess using common sense.

The values of trigonometric functions are sinα = -10 and cotα = -10/24.
What is the trigonometric functions?
In mathematics, the trigonometric functions (also called circular functions, angle functions or goniometric functions[) are real functions that relate an angle of a right-angled triangle to ratios of two side lengths.
They are widely used in all sciences that are related to geometry, such as navigation, solid mechanics, celestial mechanics, geodesy, and many others. They are among the simplest periodic functions, and as such are also widely used for studying periodic phenomena through Fourier analysis.
We have given,
tanα = -(24/10) and π α < 2π
To Find: sinα =? & cotα = ?
