Andrew's training plan can be modeled by an exponential function, and Sebastian's training plan can be modeled by a linear function. So, correct option is c) .

A linear function is a mathematical function that maps a set of inputs to a set of outputs in such a way that the output is proportional to the input. In other words, if the input changes by a certain amount, the output changes by a constant factor.

The equation of a linear function has the form:

y = mx + b

where x is the input variable, y is the output variable, m is the slope of the line, and b is the y-intercept. The slope represents how much the output changes for each unit change in the input, and the y-intercept represents the output value when the input is zero.

Linear functions are represented by straight lines on a graph. If you plot the input and output values for a linear function on a graph, the resulting points will form a straight line. The slope of the line represents the rate of change of the output with respect to the input, and the y-intercept represents the initial value of the output.

In Andrew's training plan, the weight he lifts is increasing by a constant percentage each week, which is characteristic of exponential growth. In Sebastian's training plan, the weight he lifts is increasing by a constant amount each week, which is characteristic of linear growth.

The exposure time when x = 560 is: 13.66 hour

A method of simulating the relationship between two sets of variables is quadratic regression. The outcome is a regression equation that may be applied to the data to generate predictions. The formula for the equation is: y = ax² + bx + c, where a ≠ 0. Situations that may be approximated by quadratic functions include tossing a ball, firing a cannon, jumping from a platform, and striking a golf ball. Researchers may find the quadratic model to be a useful tool for data analysis in identifying the combined impact of success objectives on academic accomplishment. We anticipate that future studies on the impact of academic performance objectives will frequently use the quadratic model to analyse their data.

Given that,

T = 0.0002x² - 316x + 127.9

exposure time = T

Now, calculate exposure time when x = 560

So, T = 0.0002x² - 0.316x + 127.9

T = 0.0002×(560)² - 0.316 × (560) + 127.9

T = 62.72 - 176.96 + 127.9

T = 13.66 hour

The least number of significant digits we can trust in the solution is 2.

The relative approximate error (RAE) of 0.004% gives us an indication of the precision of the solution at the end of an iteration, but it does not directly indicate the number of significant digits that can be trusted in the solution.

In general, the number of significant digits that can be trusted in a solution depends on several factors, such as the accuracy of the initial guess, the choice of method for finding the root, and the behavior of the function being evaluated.

As a rough estimate, it is common to assume that the number of significant digits in the solution is equal to the number of significant digits in the RAE, minus one.

In this case, the RAE is 0.004%, which has three significant digits, so the least number of significant digits we can trust in the solution would be

Step-by-step explanation:

If a triangle has one side of 7 meters and another side of 12 meters, the other side is approximately 13.928 meters long.

A triangle is a three-sided polygon that has three angles and three sides. The sides of a triangle are connected by its angles, and the sum of the angles of a triangle is always equal to 180 degrees. The length of the sides of a triangle affects the size of its angles, and the size of its angles affects the length of its sides.

Now, in the case of a triangle where one side is 7 meters and another side is 12 meters, the length of the third side can be calculated using the Pythagorean theorem.

The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides.

Mathematically, it can be written as

=> a² + b² = c²,

where a and b are the lengths of the two sides, and c is the length of the hypotenuse.

Using the Pythagorean theorem, we can find the length of the third side of the triangle. Let's call the length of the third side "x". So,

=> x² = 7² + 12² = 49 + 144 = 193.

Taking the square root of both sides, we get

x = √(193) = 13.928.

So, the third side of the triangle is approximately 13.928 meters long.

The height of the pyramid is 6 cm and the angle EBD is 36.87 degrees

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

AD = 8cm CD = 5cm CE = 10cm

Given that the apex E is directly over the centre, we have

Height (h^2) = CE^2 - AD^2

So, we have

h^2 = 10^2 - 8^2

This gives

h = 6

Here, we can use the definition of tangent which is represented as

tan(EBD) = h/AD

So, we have

tan(EBD) = 6/8

tan(EBD) = 0.75

Take the arctan of both sides

the voltage across the circuit ([tex]V_{0}[/tex]) is 80 volts.

In the superposition theorem, the voltage across any element in a linear circuit is equal to the sum of the voltages caused by each source acting independently. In other words, in a linear circuit, each source is treated as the only source, and the other sources are replaced with their internal resistances.

With the resistance value of 8 ohms, we can calculate the voltage across the circuit using the superposition theorem.

First, consider [tex]I_{1}[/tex] as the only source, and set [tex]I_{2} = 0 A[/tex]. The voltage across the circuit can be found using Ohm's law (V = IR), where R is the resistance in the circuit.

[tex]V_{1} = i1 * R = 6 A * 8 ohms = 48 V[/tex]

Next, consider [tex]I_{2}[/tex] as the only source, and set [tex]I_{1} = 0 A[/tex]. The voltage across the circuit can be found using Ohm's law (V = IR), where R is the resistance in the circuit.

[tex]V_{2} = i2 * R = 4 A * 8 ohms = 32 V[/tex]

Finally, the voltage across the circuit ([tex]V_{0}[/tex]) is the sum of the voltages found in steps 1 and 2.

[tex]V_{0} = V_{1} + V_{2} = 48 V + 32 V = 80 V[/tex]

So, the voltage across the circuit ([tex]V_{0}[/tex]) is 80 volts.

Answer:

In feet: [tex]\boxed{158,892 \textrm{ feet}}[/tex]

In miles: [tex]\boxed{\textrm{ 3.11 \;miles}}[/tex]

Step-by-step explanation:

A diagram really helps here and so I have drawn one for your understanding

From the diagram we see that Point A refers to the location of the plane when it is 50 miles away from the airport at am altitude of 30,500 feet

In a 2D coordinate system where x refers to the horizontal distance from the airport value and y refers to the altitude,
=> Point A has coordinates (50, 30500)

When the plane is 20 miles away from the airport, the altitude has dropped down to 18000 feet

This location is represented as point B(20, 18000)

The horizontal distance traveled by the plane is 50 - 20 = 30 miles

The vertical distance traveled by the plane(drop in altitude) is 30,500 - 18,000 = 12, 500

These two form the legs of a right triangle with the actual path of descent as the hypotenuse of the right triangle (see figure)

The distance c traveled by the plane is the distance from Point A to Point B which can be computed using the Pythagorean theorem given the two legs of the right triangle

The general formula is :

[tex]\mbox{\large c = \sqrt{a^{2} + b^{2}}}[/tex]

where c is the length of the hypotenuse, a and b are the lengths of the other two sides

We have a = 12, 500 feet and b = 30 miles

Convert miles to feet to get same units:

a = 12, 500 feet

b = 30 miles = 30 x 5280 feet = 158400

[tex]\mathbox{ c = \sqrt{158400^{2} + 12500^{2}}}[/tex]

[tex]c = \sqrt{25090560000 + 156250000}[/tex]

[tex]c = \sqrt{25246810000}[/tex]

[tex]\mathrm{c = 158,892.45 \;feet}\\[/tex]

[tex]\mathbox{ \textrm{c = 158,892 feet (to the nearest foot)}}[/tex]

So the distance traveled by the plane is 158, 992 feet (to the nearest foot)

This works out to 158992/5280 miles = 30.11 miles which is pretty close to 3.09
