Step-by-step explanation:

Perimeter of rectangle is \(2x^{2} +8x+16\).

The perimeter of a two-dimensional shape is the total length of the outline. To find the perimeter of a rectangle, we add the lengths of all four sides.

Given

Length of a rectangle in terms of x = \(x^{2} +2x+5\)

Width of a rectangle in terms of x = \(2x+3\)

Perimeter of rectangle = 2(length + width)

P = \(2(x^{2} +2x+5 + 2x+3)\)

P = \(2(x^{2} +4x+8)\)

P = \(2(x^{2} )+2(4x)+2(8)\)

P = \(2x^{2} +8x+16\)

Hence, Perimeter of rectangle is \(2x^{2} +8x+16\).

Step-by-step explanation:

The probability of an event {a or b} is 0.7

Probability: It is the branch of mathematics concerning numerical, descriptions of how likely an event is to occur or how likely it is that a proposition is true. the probability of an event is a number between

0 and 1.

if the two events a and b are mutually exclusive then the addition rule of probability is:

P( a or b) = P(a) + P(b) - P(a∩ b)

Given that,

P(a) = 0.6                    P(b) = 0.5

               P(a ∩ b)= 0.4

According to probability methods, if two events are mutually exclusive, then the probability of either occurring is denoted as P (a ∪ b).

Now, we know that,

P( a ∪ b) = P(a) + P(b) - P( a ∩ b)

              = 0.6 + 0.5 - 0.4

The possible values of two consecutive even integers, of which the sum of their squares is 1684, are 28 and 30 for positive integers, while for negative integers, they are  -28 and -30.

The difference between two consecutive even integers is 2.

Let the integers be a and (a+2). Then,

a² + (a + 2)² = 1684

a² + a² + 4a + 4 = 1684

2a² + 4a - 1680 = 0

a² + 2a -840 = 0

Hence, we get a quadratic equation.

There are three methods of solving a quadratic equations: by factoring, completing the square, and by using the abc formula.

Use the factoring method:

a² + 2a -840 = (a - 28) (a + 30)

a = 28  and a = -30

Hence, if the integers are positive, they are: 28 and 30.

If the integers are negative, they are -28 and -30.

The tangent vector T = (i + 3sin(t)cos^2(t))j, N = (-3sin^2(t)cos(t))i + (1 - 3sin^2(t))j, κ = 6cos(t)sin(t) / (9cos^4(t) + 9sin^4(t) - 4cos^2(t)sin^2(t))^(3/2)

The tangent vector, T, normal vector, N, and curvature, κ, for the space curve r(t) = (8cos^3 t)i + (8sin^3 t)j for 0 ≤ t ≤ π/2 are as follows:

T = (i + 3sin(t)cos^2(t))j

N = (-3sin^2(t)cos(t))i + (1 - 3sin^2(t))j

κ = 6cos(t)sin(t) / (9cos^4(t) + 9sin^4(t) - 4cos^2(t)sin^2(t))^(3/2)

To find the tangent vector, we differentiate r(t) with respect to t and normalize it to get T.

To find the normal vector, we differentiate T with respect to t, divide it by its magnitude, and multiply by -1 to get N.

To find the curvature, we use the formula κ = ||dT/dt|| / ||dr/dt||, where || || denotes the magnitude. We calculate the derivatives and substitute them into the formula to obtain κ.

The sum of interior angles of triangle sum up to 180°

Hence,

∠O + 70° + 65° = 180°

∠O = 180° - 65° - 70°

∠O = 45°

∴ The angle ∠O is 45 degrees.

Use cosine rule: a² = b² + c² - 2bc cos(A)

Hence,

TO² = 3² + 3² - 2(3)(3) cos(65)

TO² = 10.39287129

To = √10.4

TO = 3.22 ≈ 3 meters (rounded to nearest whole number)

When changing the sign of the constant a from positive to negative, the domain remains the same. But the range changes.

A function's range is the set of all values it can accept, whereas its domain is the set of all values for which it is defined.

Consider the given function f(x)=a|x|. Let us consider "a" takes positive values that is \(a\geq0\). Then, the given function is defined as follows,

\(f(x)=\begin{cases}a(x)=ax}\; &x\geq0\\{a(-x)=-ax\;&x < 0\end{cases}\)

To determine the probabilities, we can use a standard normal distribution table or a statistical software. Here are the probabilities for each scenario:

(a) P(z < 2.36) = 0.9900

(b) P(z > 2.36) = 1 - P(z < 2.36) = 1 - 0.9900 = 0.0100

(c) P(z < -1.22) = 0.1112

(d) P(1.13 < z < 3.35) = P(z < 3.35) - P(z < 1.13) = 0.9992 - 0.8708 = 0.1284

(e) P(-0.77 < z < -0.55) = P(z < -0.55) - P(z < -0.77) = 0.2912 - 0.2815 = 0.0097

(f) P(z > 3) = 1 - P(z < 3) = 1 - 0.9987 = 0.0013

(g) P(z < -3.28) = 0.0005

(h) P(z < 4.98) = 1 (since the standard normal distribution extends to positive and negative infinity)

The probabilities listed above are determined using the standard normal distribution. The standard normal distribution is a specific case of the normal distribution with a mean of 0 and a standard deviation of 1.

In the standard normal distribution, probabilities are calculated based on the area under the curve. The values in the standard normal distribution table represent the cumulative probabilities up to a certain z-score (standard deviation value).

To calculate the probabilities:

For (a), P(z < 2.36), we look up the z-score 2.36 in the standard normal distribution table and find the corresponding cumulative probability, which is 0.9900.

For (b), P(z > 2.36), we subtract the cumulative probability P(z < 2.36) from 1, as the total area under the curve is equal to 1. Thus, we get 1 - 0.9900 = 0.0100.

For (c), P(z < -1.22), we find the cumulative probability for the z-score -1.22 in the standard normal distribution table, which is 0.1112.

For (d), P(1.13 < z < 3.35), we calculate the cumulative probability for z = 3.35 and subtract the cumulative probability for z = 1.13 from it. This gives us 0.9992 - 0.8708 = 0.1284.

For (e), P(-0.77 < z < -0.55), we find the cumulative probability for z = -0.55 and subtract the cumulative probability for z = -0.77 from it. This yields 0.2912 - 0.2815 = 0.0097.

For (f), P(z > 3), we subtract the cumulative probability P(z < 3) from 1, which results in 1 - 0.9987 = 0.0013.

For (g), P(z < -3.28), we find the cumulative probability for z = -3.28 in the standard normal distribution table, which is 0.0005.

For (h), P(z < 4.98), since the standard normal distribution extends to positive and negative infinity, the probability of any value being less than 4.98 is equal to 1.

The probabilities listed are rounded to four decimal places for simplicity and clarity.
