The graph of the model is illustrated below and  the resistance when x = 85 is 1.12

The resistance of a conductor (such as a wire) is a measure of the opposition it presents to the flow of electric current. The resistance of a wire is dependent on various factors such as its length, cross-sectional area, and material. In this case, we are looking at the resistance of 1000 feet of solid copper wire, where the diameter of the wire is given in mils (0.001 inches).

The resistance of the wire can be approximated using the mathematical model:

=> y = 10,770/x² - 0.375,

where x is the diameter of the wire in mils and y is the resistance in ohms. The model is valid for values of x ranging from 5 to 100.

To complete the table, you need to plug in different values of x into the model and solve for y. For example, when x = 10,

=> y = 10,770/(10²) - 0.375 = 106.975 ohms.

The graph of the model can then be plotted by plotting the points (x,y) from the table and connecting them with a smooth curve. The graph can be used to estimate the resistance of the wire when x = 85.5 mils by finding the y-coordinate of the corresponding point on the graph.

Finally, you can use the model to algebraically confirm the estimate you found from the graph by plugging in the value x = 85.5 into the model and solving for y then we get the value as 1.12. This should give you the same answer as you found from the graph.

In conclusion, the resistance of a wire can be estimated using the mathematical model and can be used to make predictions about the resistance for different wire diameters.

The probabilities from least to greatest are P(8), P(>4), P(odd) and P(prime).

What is probability?

Calculating probability is a method of determining how likely something is to occur. The probability scale runs from 0 to 1, where 0 denotes impossible and 1 denotes certainty.

We are given that a single die is rolled 100 times.

So, the outcomes can be {1,2,3,4,5,6}

Now,

P(odd) = Probability of odd numbers

Odd numbers are 1, 3 and 5

So, P(odd) = 3/6 = 1/2

P(>4) = Probability of numbers greater than 4

Numbers greater than 4 are 5 and 6

So, P(>4) = 2/6 = 1/3

P(prime) = Probability of prime numbers

Prime numbers are 1, 2, 3 and 5

So, P(prime) = 4/6 = 2/3

P(8) = Probability of number 8

In a dice, the maximum number is 6

So, P(8) = 0

Hence, the probabilities from least to greatest are P(8), P(>4), P(odd) and P(prime).

The rocket peaks at 5000 meters above sea-level.

The height of the rocket as a function of time is given by h(t) = -5t^2 + 1000t. To find the peak, we need to find the maximum height, which can be done by taking the derivative of the function and setting it equal to zero:

h'(t) = -10t + 1000

h'(t) = 0 => t = 100

So the rocket peaks at t = 100 seconds, and to find the height at this time, we plug t = 100 into the original function:

h(100) = -5 * 100^2 + 1000 * 100 = -50000 + 10000 = 5000

Given n balls, m of which are red and n - m are blue, if a collection of n < min{m, n - m} balls is taken out at random without replacement, the probability that exactly k balls are red can be calculated using the Hypergeometric Distribution. The formula for the probability that exactly k balls are red is given by: P(k red balls) = (C(m, k) * C(n - m, n - k)) / C(n, n)

where C(n, k) denotes the number of combinations of n things taken k at a time, and is given by: C(n, k) = n! / (k! * (n - k)!).

The standard deviation of the sample mean decreases as the sample size increases. This is because the larger the sample size, the more accurately it reflects the population mean.

The standard deviation of the sample mean is a measure of how close the sample mean is to the population mean. The sample mean is an estimate of the population mean, and the standard deviation of the sample mean is a measure of how accurate that estimate is. When the sample size is increased, the sample mean becomes a more accurate estimate of the population mean, thus the standard deviation of the sample mean decreases. This is because the larger the sample size, the more accurately it reflects the population mean, and the closer the sample mean is to the population mean, the lower the standard deviation of the sample mean.

The final value of z = xy will be 1.05 times the original value.

The formula for calculating the growth rate of z = xy is z’/z = (x’/x)+(y’/y). The prime symbol (‘) denotes the rate of growth. In this case we can substitute the given rates of growth of x and y: x’/x = 2% and y’/y = 3%. By substituting these values into the formula we can calculate the rate of growth of z. z’/z = (2% + 3%) = 5%.

Therefore z = xy will grow approximately by 5%. To calculate the exact change in z, we can use the formula for compound growth: z’ = z (1 + r/100)^t, where r is the rate of growth and t is the number of time periods. In this case, r = 5% and t = 1 (as the growth rate is per period). Therefore, z’ = z (1 + 5/100)^1 = z (1.05) = z * 1.05. This means that the final value of z = xy will be 1.05 times the original value.

To find the values of the trigonometric functions of t, the tan(t) value was used to calculate the sin(t) value by using the relationship sin²(t) + cos²(t) = 1. The other trigonometric functions were calculated by using the relationship among the trigonometric functions.

Sin(t) = √(1 - (tan(t))^2) = √(1 - (-12/5)^2) = √(1 - 144/25) = √(25/25 - 144/25)   = √(1/25) = 0.2

Csc(t)= 1/0.2= 5

The radius of the circle was then determined by using the arc length and the angle subtended at the center. The arc length was divided by the subtended angle to find the radius. The result was rounded off to two decimal places.

As y varies directly as (x−2)² and y = 5/3 when x = 4, then the equation for y in terms of x is y = (5/12)(x - 2)²

If the values of y varies directly as does of x, then there is a constant say "k" that is true for them, else y does not vary directly as x.

For y = 5/3 when = 4, we can solve for the constant k as follows:

A boundary condition is a mathematical expression that describes the behavior of a physical system at its boundaries, such as a surface.

Mathematically, a perfectly insulated surface is represented as an isothermal surface, meaning that the temperature is constant across the surface.

This is described by the equation (0) = 0, where эт represents the rate of heat transfer at the surface.

In other words, a perfectly insulated surface does not allow heat to flow through it.

This equation shows that the heat transfer is in the opposite direction of the temperature gradient at the surface.

Finally, the boundary condition at a perfectly insulated surface can also be expressed as эт (0,) -k = 0, which means that the heat transfer at the surface is equal to zero and there is no net heat transfer at the surface.
