The constant of variation is 1/4 .

The inverse variation property states that , whenever the product of values of two quantities is a constant value then there is opposite variation between these two corresponding values. Or we can also say that if the productive nature of two corresponding values is constant, then one quantity is inversely varies with second quantity. That means if one value increases than another one will automatically decrease and vice versa.

Let say if x and y are two values and k is a constant value, then

According to inverse variation,

k = xy or y = k/x

In the given question,

Take the order pair  \((\frac{3}{8} ,\frac{2}{3} )\)

As it is an inverse variation, we can substitute it

y=k/x  or k = xy

put the values from order pair

k = \(\frac{3}{8}\) × \(\frac{2}{3}\)

k = \(\frac{1}{4}\)

Therefore, the constant of variation for order pair  \((\frac{3}{8} ,\frac{2}{3} )\) is 1/4 .

The slope of the line shown in the graph is __2/3__

and the y-intercept of the line is __6___

The general linear equation is written as follows:

y = ax + b

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

On the graph we can see that the y-intercept is y = 6, then we can write the line as:

y = ax + 6

The line also passes through the point (-9, 0), replacing these values in the line we will get:

0 = a*-9 + 6

9a = 6

a = 6/9

It will take a minimum of 10 clock hours (not driving hours) for the truck driver to travel 450 miles from Charlotte, NC to Pittsburgh, PA.

The current Hours of Service (HOS) rules for truck drivers stipulate that a truck driver cannot drive for more than 11 hours after 10 consecutive hours off duty.

Additionally, the driver is not allowed to drive beyond 14 hours after coming on duty.

The driver's shift includes both driving and non-driving time.

Therefore, it is necessary to consider the total amount of time spent on the job.

The truck driver will have to stop for rest breaks, refueling, or other reasons during the 450-mile journey to Pittsburgh, Pennsylvania. The driver is required to take a 30-minute break after eight hours of driving.

Therefore, the minimum number of clock hours (not driving hours) it will take the truck driver to travel the 450-mile distance from Charlotte, NC to Pittsburgh, PA is calculated as follows:

Time for the trip = (Distance ÷ Average Speed) + Breaks

Time for the trip = (450 ÷ 50) + (30 ÷ 60) × 2

Time for the trip = 9 + 1

Time for the trip = 10 clock hours

Therefore, it will take a minimum of 10 clock hours (not driving hours) for the truck driver to travel 450 miles from Charlotte, NC to Pittsburgh, PA.

David bought 12 pounds of nuts.

Given, The cost of nuts per pound is $3.75.

David paid a total of $45 for nuts.

Let's assume the pounds of nuts that David bought be x.

Total cost of nuts bought = $45

Cost per pound of nuts = $3.75

Now we need to find how many pounds of nuts did David buy.

So, the equation that relates the cost of nuts and the pounds of nuts is as follows:

Total cost of nuts bought = Cost per pound of nuts * Pounds of nuts bought

$45 = $3.75x

Solving for x,

we get; x = $45 / $3.75x

= 12 pounds.

The total arc length AB that the pendulum travels is approximately 13.96 inches.

To find the total arc length traveled by the pendulum, we can use the formula for the arc length of a pendulum given by:

Arc length (s) = θ × r

where θ is the angle in radians and r is the length of the pendulum.

However, in this case, we are given the angle in degrees, so we need to convert it to radians. The formula for converting degrees to radians is:

θ (in radians) = (π/180) × θ (in degrees)

Given that the angle is 80°, we can convert it to radians as follows:

θ (in radians) = (π/180) × 80° = (4π/9) radians

Now, we can calculate the arc length:

Arc length (s) = (4π/9) radians × 10 inches

The total arc length traveled by the pendulum is therefore:

Arc length (s) = (40π/9) inches

To approximate the answer, we can use the value of π as approximately 3.14:

Arc length (s) ≈ (40 × 3.14/9) inches

Arc length (s) ≈ 13.96 inches

Therefore, the total arc length AB that the pendulum travels is approximately 13.96 inches.

Please note that this calculation assumes that the pendulum swings in a perfect arc without any friction or external factors affecting its motion. In reality, there may be slight variations due to factors such as air resistance or imperfections in the pendulum's motion.

The seventh term of the sequence is 364.5

From the question, we are to determine the seventh term of the sequence

Using the formula,

\(a_{n} = ar^{n-1}\)

Where \(a_{n}\) is the nth term

a is the first term

and r is the common ratio

From the given information,

a = 1/2

r = 3

Thus,

\(a_{7} = (\frac{1}{2}) 3^{7-1}\)

\(a_{7} = (\frac{1}{2}) 3^{6}\)

\(a_{7} = \frac{1}{2} \times 729\)

\(a_{7} = 364\frac{1}{2} \ OR \ 364.5\)

Answer:

P(-5) = 109

Step-by-step explanation:

     If the polynomial p(x) is divided by the linear polynomial (x-a), the remainder is p(a).

   Dividend = divisor * quotient + remainder.

   p(x) = (x-a) * q(x) + p(a)

Here, q(x) is the quotient and p(a) is the remainder.

      P(x) = 4x² - x + 4

     P(-5) = 4*(-5)² - 1*(-5) + 4

              = 4*25 + 5 + 4

Step-by-step explanation:

The mean of the test is M = 53

Given data ,

On a test that has a normal distribution, a score of 47 falls one standard deviation below the mean, and a score of 65 falls two standard deviations above the mean.

Now , A score of 47 falls one standard deviation below the mean, so we have:

47 = μ - σ

A score of 65 falls two standard deviations above the mean, so we have:

65 = μ + 2σ

We now have a system of two equations with two variables (μ and σ). We can solve this system of equations to find the mean (μ).

From the first equation, we can isolate μ:

μ = 47 + σ

Substituting this value into the second equation:

65 = (47 + σ) + 2σ

65 = 47 + 3σ

Rearranging the equation:

3σ = 65 - 47

3σ = 18

σ = 6

Substituting the value of σ back into the first equation to find μ:

47 = μ - 6

μ = 47 + 6

μ = 53

Hence , the mean of the test is 53
