The quadratic function g(x) = (x - 5)² + 1 passes through the points (2, 10) and (8, 10) and has a vertex at (5, 1).

In this question we have a graph of a quadratic equation translated to another place of a Cartesian plane, whose form coincides with the vertex form of the equation of the parabola, whose form is:

g(x) = C · (x - h)² - k     (1)

Where:

By direct comparison we notice that (h, k) = (5, 1) and C = 1. Now we proceed to check if the points (x, y) = (2, 10) and (x, y) = (8, 10) belong to the parabola.

x = 2

g(2) = (2 - 5)² + 1

g(2) = 10

x = 8

g(8) = (8 - 5)² + 1

g(8) = 10

The quadratic function g(x) = (x - 5)² + 1 passes through the points (2, 10) and (8, 10) and has a vertex at (5, 1).

Step-by-step explanation:

First one 80% because it is LIKELY to occur meaning having good odds of happening.

Based on the information provided in the question:

Car b finished in the second position in the first race.

Velocity:

Velocity is the directional velocity of a moving object, observed from a given frame of reference and indicating the rate of change of position measured at a given time reference (eg 60 km/h northward). Velocity is a fundamental concept in kinematics, a branch of classical mechanics that describes the motion of bodies.

Velocity is a physical vector quantity. Both magnitude and direction are required to define it. The scalar absolute value (magnitude) of velocity is called velocity, and its magnitude is a consistent derived unit measured in the SI (metric) system as meters per second (m/s or m⋅s−1). For example, "5 meters/second" is a scalar, but "5 meters/second east" is a vector. An object is said to be accelerating if its velocity, direction, or both change.

According to the question:

Let tₐ = time of finish of car A in sec

Let \(t_b\)= time of finish of car B in sec

Let \(t_c\)  = time of finish of car C in sec

Let \(t_d\) = time of finish of car D in sec

Let \(t_e\) = time of finish of car E in sec

According to the above information:

(1) \(t_a = t_d -1\)

(2) \(t_b= t_e -6\)

(3) \(t_e =t_a +3\)

(4) \(t_a = t_c+5\)

Now,

From (3),

(3) \(t_a = t_e -3\)

and

(2) \(t_e =t_b+6\)

and

(1)\(t_d =t_a +1\)

Therefore, the series would be

The approximate probability that a randomly chosen 10-year-old is between 60 and 65 inches is 15.58%.

To solve this problem, we need to standardize the values using the z-score formula:

z = (x - μ) / σ

where x is the value we want to find the probability for, μ is the mean, and σ is the standard deviation.

In this case, we want to find the probability that a randomly chosen 10-year-old is between 60 and 65 inches, so:

z1 = (60 - 55) / 6 = 0.83

z2 = (65 - 55) / 6 = 1.67

We can use a standard normal distribution table or calculator to find the probabilities associated with these z-scores.

P(0.83 < z < 1.67) = P(z < 1.67) - P(z < 0.83)

Using a standard normal distribution table or calculator, we find that P(z < 0.83) = 0.7967 and P(z < 1.67) = 0.9525.

So,

P(0.83 < z < 1.67) = 0.9525 - 0.7967 = 0.1558

Therefore, the approximate probability that a randomly chosen 10-year-old is between 60 and 65 inches is 0.1558, or about 15.58%.

Using trigonometric substitution and solving  ∫√y²−25y³dy we get, ∫(5√(125/2))(cosθ)((1 - cos2θ)/2) dθ.

What is an integral?

An integral is a fundamental concept in calculus that represents the accumulation or total of a quantity over an interval.

What is trigonometric substitution?

Trigonometric substitution is a technique used in calculus to simplify integrals involving expressions that contain square roots or higher powers of trigonometric functions. It is particularly useful when dealing with algebraic expressions that can be rewritten in terms of trigonometric functions.

To solve the integral ∫√(y² - 25y³) dy using trigonometric substitution, we can proceed as follows:

Let's make the substitution y = 5sin²θ. This substitution is chosen because it simplifies the integral by transforming the radical expression into a trigonometric function.

Differentiating y = 5sin²θ with respect to θ, we get:

dy/dθ = 10sinθcosθ dθ

To express dy in terms of dθ, we can solve for dθ:

dθ = (dy / (10sinθcosθ))

Substituting y = 5sin²θ and dy = 10sinθcosθ dθ into the integral, we have:

∫√(y² - 25y³) dy = ∫√((5sin²θ)² - 25(5sin²θ)³) * 10sinθcosθ dθ

Simplifying the expression inside the square root:

∫√(25sin⁴θ - 125sin⁶θ) * 10sinθcosθ dθ

∫√(25sin⁴θ(1 - 5sin²θ)) * 10sinθcosθ dθ

Using trigonometric identities, we can rewrite sin²θ = (1 - cos2θ)/2:

∫√(25(sin⁴θ)(1 - 5sin²θ)) * 10sinθcosθ dθ

∫√(25(sin⁴θ)(1 - 5(1 - cos2θ)/2)) * 10sinθcosθ dθ

∫√(25(sin⁴θ)(1 - 5 + 5cos2θ)/2) * 10sinθcosθ dθ

∫√((25/2)(5cos2θ - 4cos²θ)) * 10sinθcosθ dθ

Simplifying further:

∫√((125/2)(cos2θ - cos²θ)) * 10sinθcosθ dθ

Using the trigonometric identity cos2θ = 2cos²θ - 1:

∫√((125/2)(2cos²θ - cos²θ - 1)) * 10sinθcosθ dθ

∫√((125/2)(cos²θ - 1)) * 10sinθcosθ dθ

Factoring out the constant:

∫(5√(125/2))(cosθ)(sinθ)√(1 - cos²θ) dθ

The expression (√(1 - cos²θ)) is equivalent to sinθ, so we can further simplify:

∫(5√(125/2))(cosθ)(sinθ)√(1 - cos²θ) dθ

∫(5√(125/2))(cosθ)(sinθ)(sinθ) dθ

∫(5√(125/2))(cosθ)(sin²θ) dθ

Using the identity sin²θ = (1 - cos2θ)/2:

∫(5√(125/2))(cosθ)((1 - cos2θ)/2) dθ

Therefore, using trigonometric substitution the answer is ∫(5√(125/2))(cosθ)((1 - cos2θ)/2) dθ

The probability of selecting a red marble followed by a yellow marble, with replacement, can be found to be 1/6.

When a marble is selected with replacement, it means that after each draw, the marble is placed back into the bag, and the total number of marbles remains the same. Since there are 3 red marbles out of a total of 6 marbles in the bag, the probability of selecting a red marble on the first draw is 3/6.

After replacing the marble, the bag still contains 6 marbles, but the number of red marbles remains the same (3) and the number of yellow marbles remains the same (2). Therefore, the probability of selecting a yellow marble on the second draw is 2/6.

To find the probability of both events occurring, we multiply the probabilities:

P(Red then Yellow) = (3/6) × (2/6) = 1/6.

Therefore, the probability of drawing a red marble followed by a yellow marble is 1/6.

The transfer function H(s) is given by the ratio of the output Y(s) to the input U(s):

H(s) = Y(s)/U(s) = C(sI - A)^(-1)B + D

To find the open-loop transfer function H(s) associated with the given state equations, we need to perform a Laplace transform on the state equations.

The state equations can be written in matrix form as:

ẋ(t) = A*x(t) + B*u(t)

y(t) = C*x(t) + D*u(t)

Where:

ẋ(t) is the vector of state derivatives,

x(t) is the vector of state variables,

u(t) is the input,

y(t) is the output,

A is the system matrix,

B is the input matrix,

C is the output matrix,

D is the feedforward matrix.

Given the system matrices:

, C = [100 20 10 0], and D = [0]

We can write the state equations in Laplace domain as:

sX(s) = AX(s) + BU(s)

Y(s) = CX(s) + DU(s)

Where:

X(s) is the Laplace transform of the state variables x(t),

U(s) is the Laplace transform of the input u(t),

Y(s) is the Laplace transform of the output y(t),

s is the complex frequency variable.

Rearranging the equations, we have:

(sI - A)X(s) = BU(s)

Y(s) = CX(s) + DU(s)

Solving for X(s), we get:

X(s) = (sI - A)^(-1) * BU(s)

Substituting X(s) into the output equation, we have:

Y(s) = C(sI - A)^(-1) * BU(s) + DU(s)

Finally, the transfer function H(s) is given by the ratio of the output Y(s) to the input U(s):

H(s) = Y(s)/U(s) = C(sI - A)^(-1)B + D

Substituting the values of A, B, C, and D into the equation, we can calculate the open-loop transfer function H(s).

The sum of the angle measures of the polygon is 540°, the value of x is 5.

The sum of the angle measures of the polygon is 540°.

We know that the sum of the interior angles of a polygon of n sides = (n – 2) × 180°. = 3× 180°= 540°

If a polygon has x sides, then the sum of its angle measures can be found using the formula:

Therefore, for a polygon with x sides, the equation becomes:

⇒(x-2) * 180° = 540°

Solving for x, we get:

⇒x = (540° + 360°) / 180° + 2

⇒x = 3 + 2

⇒x = 5

So, the polygon has 5 sides.

Therefore, the value of  x is 5.
