The equation in slope intercept form to represent the equation is y = 2.5x

From the question, we have the following parameters that can be used in our computation:

The graph

On the graph, we have the following points

(x, y) = (0, 0) and (10, 25)

A linear equation is represented as

y = mx + c

Where

c = y when x = 0

So, we have

y = mx + 0

y = mx

Next, we have

25 = 10m

This gives

m = 2.5

So, we have

y = 2.5x

Hence, the equation is 2.5x

Step-by-step explanation:

To solve the system of equations:

5x + y = 9

10x - 7y = -18

We can use the elimination method by multiplying the first equation by 7 and subtracting it from the second equation:

35x + 7y = 63 (multiplying first equation by 7)

10x - 7y = -18

45x = 45

Dividing both sides by 45, we get:

x = 1

Substituting x = 1 into the first equation:

5(1) + y = 9

Simplifying, we get:

y = 4

Therefore, the solution to the system of equations is x = 1 and y = 4.

Step-by-step explanation:

If a projectile ascends vertically, and after 3 seconds it reaches its maximum height, calculate the velocity that it carries to the middle of its downward trajectory

Let the maximum height is h and initial velocity is u.

From first equation of motion

v = u + at

0 = u - g x 3

u = 3 g.....(1)

Use third equation of motion

\(v^2 = u^2 - 2 gh \\\\0 = 9 g^2 - 2 gh \\\\h = 4.5 g\)

Let the speed at half the height is v'.

\(v^2 = u^2 + 2 gh \\\\v'^2 = 0 + 2 g\times 2.25 g\\\\v'^2 = 4.5\times 9.8\times9.8\\\\v' = 20.8 m/s\)

Answer: 36.25°

Step-by-step explanation:

Use SOHCAHTOA (sin, cosine and tangent)

SOHCAHTOA:

SOH: Sin(θ) = Opposite / Hypotenuse

CAH: Cos(θ) = Adjacent / Hypotenuse

TOA: Tan(θ) = Opposite / Adjacent

When you have an angle that you want to solve, look at what information you're given. In this problem, we're give nthe sides that are opposite to and adjacent to the angle we want to solve. So, we use TAN.

And just as a note, θ this symbol is called theta, and it represents an angle.

TAN(θ) = Opposite / Adjacent = 11/15

Then, use the inverse of tan (you can find the button on a calculator). You can use the inverse of sine, cosine or tangent whenever you want to switch them from one side of the equation to the other.

TAN(θ) = \(\frac{11}{15}\)

θ = \(tan^-1(\frac{11}{15} )\)

Then, using a calculator, solve. The answer is about 36.25°

Hi Student!

This question is pretty straight-forward because it is asking for us to solve to equation using square roots.  We don't need to find any important information as this problem is pretty simple.  We just need to use some algebra to move numbers around and we will get our answer.

Add 81 to both sides

Square root both sides

Therefore, after solving for x we were able to determine that the solutions that we have for this equation are both 9 and -9.  If we want to test this we can plug in the values into x and we would see that both 9 and -9 would produce the same results as negatives don't matter when we are squaring numbers.

Answer:

Perpendicular, CD has a slope of -5/2

Step-by-step explanation:

Parallel lines have the same slope, perpendicular have slopes that are negative reciprocals, or in other words if one slope is m then the other's slope is -1/m and if it is neither fo those then it is neither parallel or perpendicular.  Also,  if two lines have the same slope you have to make sure they are not the same line.  

Now, to find the slope  when you have two points you use the formula (y2 - y1)/(x2 - x1), where the points are (x1, y1) and (x2, y2).  You can make either point point 1 or point 2.  Just make sure x1 and y1 are from one point and x2 and y2 are from the other point.  

So the two lines are AB and CD.  Since the question asks I will start with CD.  The points are (1,8) and (3,3)  So I will call C point 1 and D point 2.  

(y2 - y1)/(x2 - x1)

(3 - 8)/(3 - 1)

-5/2

Thankfully this is lowest terms.

Now for AB.  A will be point 1 and B will be point 2

(y2 - y1)/(x2 - x1)

(4-2)/(5-0)

2/5

So they are not the same, so what if you take negative 1 over one of the slopes.  

well. -1/(2/5) = -5/2

So these are perpendicular.  

If you would like an explanation for how to find the full equation of a line I can explain that.

Mean  is 14.5 years and standard deviation is 0.34 years

The standard deviation is a measurement of how much a group of values vary or are dispersed. While a high standard deviation suggests that the values are dispersed throughout a wider range, a low standard deviation suggests that the values tend to be close to the established mean.

Given in the question:

Mean = 14.5 years, standard deviation, σ = 2.5 years and Sample size = 55 students.

The mean of the sample of 55 students will now stay the same for 14.5 years, and the formula will be used to determine the sample's standard deviation.:

= σ/√n

here n is the sample size

thus, Standard deviation of the sample of 55 students, σₓ =  \(\frac{2.5}{\sqrt{55} }\)

= 0.337 ≈ 0.34

Hence, the Mean  = 14.5 years and standard deviation = 0.34 years.

Mean of the sampling distribution is 14.5 . Standard Deviation of the sampling distribution is 0.45

The mean of the sampling distribution is equal to the mean of the population, which in this case is 14.5 years.

The standard deviation of the sampling distribution is calculated using the following formula:

Standard deviation of the sampling distribution \(= \frac{standard \ deviation \ of \ the \ population}{sample \ size}\)

Plugging in the values given in the problem, we get:

Standard deviation of the sampling distribution = \(\frac{(2.5 years)} {\sqrt55}= 0.45\) years

So the mean of the sampling distribution is 14.5 years, and the standard deviation of the sampling distribution is 0.45 years.

Standard deviation is a measure of the spread or dispersion of a set of data values. It is the square root of the variance, which is defined as the average of the squared differences from the mean. It is used to calculate how much variation exists from the average (mean) value of a set of data.

Based on the product of powers rule, the missing power in the given calculation is 2/3.

The product of powers rule is used in simplifying exponents. In a given term a^x, a number or variable raised to a power is called the base, while the superscript number is called the exponent, or power. According to the rule, if the bases are the same in the multiplication problem, it can be simplified by adding the exponents. Hence, for any number a and all integers m and n:

a^m * a^n = a^(m+n)

The given calculation is:

5^1/3*5^□ = 5

5^1/3*5^□ = 5^1

Hence, the sum of the powers would be one. Let the missing power be x. Therefore,

The measure of the arc angle JA is 76 degrees.

The sum of angles in a cyclic quadrilateral is 360 degrees. The opposite angles in a cyclic quadrilateral is supplementary.

The measure of an arc intercepted by an angle of a quadrilateral that is inscribed in a circle is equal to two times the measure of the inscribed angle.

Therefore,

26x + 1 = 1 / 2 (18x + 4 + 6 + 32x)

26x + 1 = 1 / 2 (50x + 10)

26x + 1 = 25x + 5

26x - 25x = 5 - 1

x = 4

Therefore,

arc angle JA = 18x + 4

arc angle JA = 18(4) + 4

arc angle JA =72 + 4

A firm using two inputs, x and y, is using them in the most efficient manner when it is producing the maximum output with the given inputs or it is producing a given output with minimum input cost.

This is known as the concept of efficiency or optimization in economics.

Mathematically, if the firm is maximizing its output subject to a given cost constraint, the optimization problem can be stated as follows:

Maximize f(x, y)

Subject to: p_x*x + p_y*y <= C

Where f(x, y) is the production function representing the output produced with inputs x and y, p_x and p_y are the prices of the inputs, and C is the total cost available to the firm.

Similarly, if the firm is minimizing its input cost subject to a given level of output, the optimization problem can be stated as:

Minimize C = p_x*x + p_y*y

Subject to: f(x, y) = Y

Where Y is the desired level of output, and C is the cost of the inputs x and y.

The solutions to these optimization problems give the efficient or optimal input combination for the firm, which can be used to produce the maximum output or achieve the given output level at minimum cost.

Mean number of hours watched: 12

Median number of hours watched: 13.5

Step-by-step explanation:

To find the mean and median number of hours for the students, we'll use the following data:

12, 4, 19, 16, 7, 8, 15, 15

Mean:

To find the mean (average), we sum up all the numbers and divide the sum by the total count.

Sum = 12 + 4 + 19 + 16 + 7 + 8 + 15 + 15 = 96

Count = 8

Mean = Sum / Count = 96 / 8 = 12

Therefore, the mean number of hours watched is 12.

Median:

To find the median, we arrange the numbers in ascending order and determine the middle value.

Arranged in ascending order: 4, 7, 8, 12, 15, 15, 16, 19

Since we have 8 values, the median will be the average of the two middle values, which are 12 and 15.

Median = (12 + 15) / 2 = 27 / 2 = 13.5

Therefore, the median number of hours watched is 13.5 (rounded to the nearest tenth).

Without the specific information about the production rate and flow rate of the process, it is not possible to provide a precise calculation of the WIP inventory accumulation between steps a and b in 16 hours.

To determine the number of units of work-in-process (WIP) inventory that will accumulate between steps a and b in 16 hours, we need additional information regarding the production rate and the flow rate of the process. The accumulation of WIP inventory depends on the production rate and the time it takes for a unit to flow from step a to step b.

Without specific information about the production rate or the time it takes for a unit to flow from step a to step b, it is not possible to provide an accurate calculation of the WIP inventory accumulation.

However, I can explain the concept of WIP inventory and its accumulation in a manufacturing process.

WIP inventory refers to the partially completed units that are in the production process at any given time. It includes all the materials, components, and partially completed products that are at various stages of the production process.

The accumulation of WIP inventory occurs when the production rate exceeds the flow rate of the process. In other words, if the rate at which new units enter the process is higher than the rate at which units move from one step to another, WIP inventory will accumulate.

To calculate the accumulation of WIP inventory, we need to know the production rate, the flow rate, and the time period over which we want to measure the accumulation. With this information, we can determine the net inflow rate and the outflow rate of units from the process.

Once we have the inflow and outflow rates, we can calculate the net accumulation of WIP inventory by subtracting the outflow rate from the inflow rate. Multiplying this net accumulation rate by the given time period will give us the total accumulation of WIP inventory.

However, without the specific information about the production rate and flow rate of the process, it is not possible to provide a precise calculation of the WIP inventory accumulation between steps a and b in 16 hours.

In conclusion, to determine the number of units of WIP inventory that will accumulate between steps a and b in 16 hours, we need additional information about the production rate and the flow rate of the process. These factors are essential in calculating the net accumulation of WIP inventory. Without this information, it is not possible to provide an accurate answer.
