Answer:

Step-by-step explanation:

The value of cos(x/2) is required.

The required value is \(\cos(x/2)=-\sqrt{\dfrac{5-2\sqrt{5}}{10}}\)

The given value is

\(\tan x=\dfrac{1}{2}\) where x is in quadrant III.

From trigonometric identities we have

\(\sec^2x=1+\tan^2x\\\Rightarrow \sec^2x=1+(\dfrac{1}{2})^2\\\Rightarrow \sec^2x=\dfrac{5}{4}\\\Rightarrow \cos^{2}x=\dfrac{4}{5}\\\Rightarrow \cos x=\dfrac{2}{\sqrt{5}}\)

If x lies in quadrant III then x/2 lies in quadrant II.

Cos is negative in quadrant III so,

\(\cos x=-\dfrac{2}{\sqrt{5}}=-\dfrac{2\sqrt{5}}{5}\)

\(\cos \dfrac{x}{2}=\pm \sqrt{\dfrac{1+\cos x}{2}}\\ =\pm\sqrt{\dfrac{1-\dfrac{2\sqrt{5}}{5}}{2}}\\ =\pm\sqrt{\dfrac{5-2\sqrt{5}}{10}}\)

Since, x/2 lies in the second quadrant and cos (x/2) is negative.

The required value is \(-\sqrt{\dfrac{5-2\sqrt{5}}{10}}\)

a = 4, b = -21, c = -18

to keep from getting "mixed up", evaluate the discriminant first ...

b² - 4ac = (-21)² - 4(4)(-18) = 729

sqrt(729) = 27

x = (21 +/- 27)/8

x = -3/4, x = 6

since the discriminant is a perfect square, the original quadratic will factor ...

4x² - 21x - 18 = 0

(4x + 3)(x - 6) = 0

x = -3/4, x = 6

Answer:729

Step-by-step explanation: Use the values of a, b and c to find the discriminant. Which is 729

To design ac to meet the specifications in problem 1c, we need to determine the desired closed-loop pole location. Once we have the desired pole location, we can design the PD compensator to place one of the poles at that location.

To design a PID compensator to meet the specifications in problem 1b, we need to consider both the desired pole location and zero location. The pole location determines the system's transient response, while the zero location affects the steady-state response. By adjusting the locations of the pole and zero, we can achieve the desired performance specifications.

To sketch the , we plot the loci of the closed-loop poles as we vary the compensator gain. We include the effect of the compensator in the open-loop transfer function and analyze how the poles move in the complex plane. The sketch helps us understand the stability and transient response characteristics of the system with the compensator

To obtain MATLAB plots of the step and ramp responses for the PD and PID compensators, we can use the `step` and `lsim` functions in MATLAB. By simulating the response of the system with different compensator gains, we can observe the system's performance in terms of settling time (Ts), maximum overshoot (Mp), and steady-state error. We can adjust the compensator parameters until the desired performance specifications are met. Overall, designing the PD and PID compensators involves determining the desired closed-loop pole and zero locations, sketching the compensated root locus, and simulating the system's response using MATLAB to fine-tune the compensator parameters and meet the given specifications.

What exactly are expressions?

Expressions in mathematics are mathematical assertions that comprise at least two phrases that contain numbers, variables, or both, and are connected by an operator in between. Addition, subtraction, multiplication, and division are examples of mathematical operators. For example, x + y is an expression in which x and y are terms separated by an addition operator. There are two sorts of expressions in mathematics: numerical expressions, which include simply numbers, and algebraic expressions, which contain both numbers and variables.

e.g. A number is 6 more than half of another number, which is x. In a mathematical expression, this proposition is expressed as x/2 + 6. Complex riddles are solved using mathematical expressions.

In Analysis of variance,  X (bar) is not affected by whether or not the population means are equal.

Analysis of variance  is a statistical method for examining differences in means. It consists of a number of statistical models and the accompanying estimating techniques (such as the "variation" within and between groups). Ronald Fisher, a statistician, created Analysis of variance. The rule of total variance, on which the Analysis of variance is based, divides the observed variance in a given variable into components owing to various causes of variation.

ANOVA generalizes the t-test beyond two means by offering a statistical test to determine if two or more population means are equal. In other words, the Analysis of variance is employed to determine whether two or more means differ from one another.

The diver collected water samples at every 3 meters, starting from 5 meters below the water surface, up to a final depth of 35 meters.

We can find the number of samples collected by dividing the total depth range by the distance between each sample and then adding 1 to include the first sample.

The total depth range is:

35 m - 5 m = 30 m

The distance between each sample is 3 m, so the number of samples is:

(30 m) / (3 m/sample) + 1 = 10 + 1 = 11

Therefore, the diver collected a total of 11 water samples.

Answer:

Kylie needs 58 m of fencing to fencing material to go around her lend.

Given that,
Kylie needs to build a fence around her land to keep her dog in.
Her land is a rectangle that is 15m long and 14m wide.

The rectangle is a four-sided polygon whose opposites sides are equal and has an angle of 90° between its sides.

Perimeter is the measure of the figure on its circumference.

Since in question how many meters of fencing material will kylie need to go all around her land is to be determined.

From the given, we have the length and width of rectangle land which are 15 m  and 14 m respectively.

Since Kylie needs to do fencing all around her land so she must know the perimeter of her land in order to evaluate how much fencing material will be needed.

Perimeter of her land = 2  * length + 2 * width
                                 = 2 * 15 + 2 * 14
                                 =  58 m

To show that the pmf of W = X + Y is given by the convolution formula h(w) = ∑f(x)g(w-x) for w = 0, 1, 2, ..., let's follow these steps:

Step 1: Express the probability of W = w.
We need to find the probability of W = w, which can be written as P(W = w) = h(w).

Step 2: Recognize the mutually exclusive events.
As hinted, there are w+1 mutually exclusive events corresponding to (x, y) pairs, where x = 0, 1, 2, ..., w and y = w - x. Since X and Y are independent, the probability of each pair is the product of their individual probabilities: P(X = x) * P(Y = w - x).

Step 3: Use the independence of X and Y.
Since X and Y are independent, we can use their respective pmfs, f(x) for X and g(y) for Y. Thus, the probability of each pair becomes f(x) * g(w - x).

Step 4: Sum over all mutually exclusive events.
Now, we sum the probabilities of all these mutually exclusive events to get the probability of W = w:
h(w) = ∑f(x)g(w-x) for x = 0, 1, 2, ..., w.

So, the pmf of W = X + Y is given by the convolution formula h(w) = ∑f(x)g(w-x) for w = 0, 1, 2, ....

To show that the pmf of W = X+Y is given by the convolution formula h(w)=\sum_{x=0}^{w}f(x)g(w-x), w=0, 1, 2, ... , we will follow these steps:
Step 1: We want to find the probability h(w) = P(W = w), where W = X + Y.
Step 2: Rewrite h(w) in terms of X and Y probabilities.
h(w) = P(X + Y = w)
Step 3: Apply the independence property of X and Y. Since X and Y are independent, we know that the joint probability mass function (pmf) is the product of their individual pmfs: P(X=x, Y=y) = f(x)g(y).
h(w) = \sum_{x=0}^{w} P(X=x, Y=w-x)
Step 4: Sum over all possible values of X that satisfy the condition.
h(w) = \sum_{x=0}^{w} f(x)g(w-x)
So, the pmf of W = X+Y is given by the convolution formula h(w)=\sum_{x=0}^{w}f(x)g(w-x), w=0, 1, 2, ...
