The line created by the ends of phasors whose lengths represent the magnitude, or amplitude gain, of the system and which are drawn at angles according to their phase is known as the polar plot of the frequency response of a system.

In a polar plot, the area between the curve and the origin is shown as a shaded region. You can use the definite integral to calculate the area of this area. The following is the general formula for calculating the distance between a polar curve and the origin:

A = 1/2 * ∫r^2 dθ from θ1 to θ2

where r = 4 + 3 sin(θ) and θ1 and θ2 represent the bounds of the shaded region in terms of theta.

To find the exact bounds, you need to determine the values of θ for which the curve intersects the r-axis (i.e., when sin(θ) = 0). In this case, r = 4 and θ = 0, 2π, 4π, ...

The probability of getting an odd number or number less than three is 5 / 6.

Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

Probability = Number of favourable outcomes / Number of samples

The samples are given below:-

S = { 1, 2 , 3 , 4 , 5 , 6 }

Favourable outcome = Odd numbers = { 1 , 3 , 5 } = 3

Less than three = { 1 , 2 } = 2

The probability will be calculated as:-

Probability = ( 3 / 6 )  + ( 2 / 6 )

Probability = ( 1 / 2 )  + ( 1 / 3 )

The hint about this being a linear function is a critical piece of information.

A linear function has a fixed slope, so you can use the slope formula to find that slope using the two given points, (-3,-5) and (-1,-1).

        [tex]m=\dfrac{y_2-y_1}{x_2-x_1} = \dfrac{-1-(-5)}{-1-(-3)} = \dfrac{4}{2}=2[/tex]

Now you can use that slope and a point to find the equation of the function.

g(x) = mx + b, but m=2, so g(x) = 2x + b

If we plug in one of the points, we can calculate b:

     -5 = 2(-3) + b

     -5 = -6 + b

       1 = b

Now you have your function: g(x) = 2x + 1

You can use it to calculate the missing values in the table.

The function phi(x) = 2/1-ce³ˣ  is a one-parameter family of solutions to the differential equation dy/dx = 3y² - 6y/2.

A function is a one-parameter family of solutions to a differential equation if it satisfies the equation for all values of the arbitrary constant "c".

In this case, the function phi(x) = 2/1-ce³ˣ is a one-parameter family of solutions to the differential equation because, no matter what the value of "c" is, the function will always satisfy the equation.

So, when we say that

=> phi(x) = 2/1-ce³ˣ

is a one-parameter family of solutions to the differential equation

=> dy/dx = 3y² - 6y/2,

we mean that the function can be used to describe the rate of change of y with respect to x for a range of values of y.

By changing the value of the constant "c", we can get different specific solutions to the differential equation, each corresponding to a different curve in the x-y plane.

x*0.1 + y*0.25 =7.35

x+y =39 so x = 39-y

(39-y)*0.1 +0.25y =7.35

0.15y = 3.45

y=23

Speed of a car traveling 5 miles in 20 minutes is 0.25 miles/ min.

To calculate the speed of a car, we can divide the total distance it has traveled by the time it took to travel that distance. In this case, the car traveled 5 miles in 20 minutes.

Speed = Distance ÷ Time

Speed = 5 miles ÷ 20 minutes = 0.25 miles/minute

So, the car was traveling at a speed of 0.25 miles per minute, or 15 miles per hour.

It's important to note that this speed only tells us how fast the car was moving at a specific moment in time, and it might have changed throughout its journey. Additionally, this calculation assumes that the car was traveling at a constant speed, which might not always be the case. To get a more accurate representation of the car's speed, we would need to take into account its speed at various points along its route and average those speeds over the entire journey.

Answer:

square root of (l^2 + b^2)

The formula for the diagonal of a rectangle is given by the d = √(l² + w²).

What is the length of the diagonal of the rectangle?

We can find the diagonal of a rectangle if you have the width and the height. The diagonal equals the square root of the width squared plus the height squared.

The diagonal of a rectangle is a line segment connecting two opposite corners of the rectangle and passes through the interior of the rectangle.

The formula for the diagonal of a rectangle is given by the Pythagorean theorem:

d = √(l^2 + w^2)

Where,

d is the length of the diagonal,

l is the length of the rectangle,

and w is the width of the rectangle.

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

In the case of a rectangle, the two shorter sides are the length and the width of the rectangle, and the longest side is the diagonal.

Therefore, the diagonal of a rectangle can be considered as the hypotenuse of a right triangle with sides equal to the length and width of the rectangle.

The four random errors of his measurement are 0.0, 0.1, 0.1, and 0.0.

Random errors are errors in experimental measurements that are caused by unpredictable and unknown changes in the experiment and do not occur in any describable pattern. One example of random errors is Measuring blood pressure.

Bias or systematic errors are due to chance and their source of error is detectable. This type of error can be calculated for an experiment and then it can be added to the measurements that we take.

We know that the Measured value = the Real value of the experiment + Random errors + Systematic errors (Bias). So, to calculate the random error we have to deduct the real value and the systematic error or bias from the measured value of the experiment.

That is,

Random error in 1st observation = 3.0 - 2.9 - 0.1 = 0.0

Random error in 2nd observation = 2.9 - 2.9 - 0.1 = - 0.1

Random error in 3rd observation = 3.1 - 2.9 - 0.1 = 0.1

where θ is the angle between vectors A and n.

The projection of A onto a plane perpendicular to n can be represented as:

A - (An) = A - (||A||cos(θ))n = ||A||sin(θ)nₜ,

where nₜ is a unit vector perpendicular to n.

Combining these two results, we have:

A = (An) + (A - (An)) = (||A||cos(θ))n + ||A||sin(θ)nₜ
