The angle of incidence can be found using Snell's law: n1 * sin(theta1) = n2 * sin(theta2), where n1 and n2 are the indices of refraction of the two mediums and theta1 and theta2 are the angles of incidence and refraction, respectively.

a. The angle of incidence can be found by rearranging Snell's law and substituting the given values:

n1 * sin(theta1) = n2 * sin(theta2)

sin(theta1) = (n2 / n1) * sin(theta2)

sin(theta1) = (1 / 1.31) * sin(38 degrees)

theta1 = arcsin((1 / 1.31) * sin(38 degrees))

b. To find the angle of refraction in the water, we need to use Snell's law again, this time with the indices of refraction of ice and water:

n1 * sin(theta1) = n2 * sin(theta2)

sin(theta2) = (n1 / n2) * sin(theta1)

sin(theta2) = (1.31 / n2) * sin(theta1)

theta2 = arcsin((1.31 / n2) * sin(theta1))

The probability of Anne's name being added to the winners' board is 0.0625, or 6.25%.

Based on the information given, we know that Anne comes in first place half of the time. This means that her probability of winning a single race is 0.5 or 50%.

To calculate the probability of her winning all 4 races in the tournament, we need to multiply her probability of winning each individual race together.

So, the probability of Anne winning the first race is 0.5, the probability of her winning the second race is also 0.5, and so on. Therefore, the probability of Anne winning all 4 races is:

0.5 x 0.5 x 0.5 x 0.5 = 0.0625 or 6.25%

So, it is quite unlikely that Anne's name will be added to the winners' board if she needs to win all 4 races in the tournament. However, if there are other factors that can contribute to her name being added to the board (such as cumulative scores), then her chances may be better.

For function linear approximation would be (i) y = f(x) = (x - 4), xo = 5:

a. Compute the linear approximation of f(x) around xo:

To compute the linear approximation of f(x) around xo, we use the formula for the linear approximation (or tangent line) at xo:

L(x) = f(xo) + f'(xo)(x - xo)

In this case, f'(x) represents the derivative of f(x).

The derivative of f(x) = (x - 4) is f'(x) = 1.

Plugging in xo = 5 and f'(xo) = 1, we have:

L(x) = f(5) + f'(5)(x - 5)

    = (5 - 4) + 1(x - 5)

    = 1 + (x - 5)

    = x - 4

Therefore, the linear approximation of f(x) around xo = 5 is L(x) = x - 4.

b. Compute the linearized/approximated value of f(x) at:

(i) x = 6:

To compute the linearized value of f(x) at x = 6, we substitute x = 6 into the linear approximation:

L(6) = 6 - 4

    = 2

(ii) x = 3.5:

To compute the linearized value of f(x) at x = 3.5, we substitute x = 3.5 into the linear approximation:

L(3.5) = 3.5 - 4

       = -0.5

For function (ii) y = [tex]f(x) = (1 + 2x)^2, xo = 4:[/tex]

a. Compute the linear approximation of f(x) around xo:

To compute the linear approximation of f(x) around xo, we use the same formula as before:

L(x) = f(xo) + f'(xo)(x - xo)

The derivative of [tex]f(x) = (1 + 2x)^2 is f'(x) = 4(1 + 2x).[/tex]

Plugging in xo = 4 and f'(xo) = 4(1 + 2(4)) = 36, we have:

L(x) =[tex]f(4) + f'(4)(x - 4)[/tex]

    = [tex](1 + 2(4))^2 + 36(x - 4)[/tex]

   [tex]= 25 + 36(x - 4) = 36x - 71[/tex]

Therefore, the linear approximation of f(x) around xo = 4 is L(x) = 36x - 71.

b. Compute the linearized/approximated value of f(x) at:

(i) x = 6:

To compute the linearized value of f(x) at x = 6, we substitute x = 6 into the linear approximation:

L(6) = 36(6) - 71

    = 185

(ii) x = 3.5:

To compute the linearized value of f(x) at x = 3.5, we substitute x = 3.5 into the linear approximation:

Step-by-step explanation:

The rate at which the searchlight is rotating when Sophie is at 10 ft from the point on the path closest to the searchlight is approximately -0.005 rad/s.

Let O be the position of the searchlight, and let A be the point on the path closest to the searchlight. Let B be Sophie's current position on the path, and let C be the foot of the perpendicular from B to the line OA, as shown in the diagram below:

           O

          /|

         / |

        /  |

       /   |20 ft

      /θ   |

     /     |

    /_ _ _A|

   B     C

Since Sophie is walking at a speed of 2 ft/s, we have BC = 2t, where t is the time elapsed since she passed through A. By the Pythagorean theorem, we have AC = sqrt(20^2 + BC^2) = sqrt(400 + 4t^2).

Differentiating both sides with respect to time, we get:

d/dt (AC) = d/dt (sqrt(400 + 4t^2))

= 4t / sqrt(400 + 4t^2)

When Sophie is at 10 ft from A, we have BC = 10 ft and t = 5 s. Therefore, AC = sqrt(400 + 45^2) = 10sqrt(5) ft.

The distance from the searchlight to Sophie is always constant at 20 ft, so we can write:

OA = AC + 20

= 10*sqrt(5) + 20

Differentiating both sides with respect to time, we get:

d/dt (OA) = d/dt (10*sqrt(5) + 20)

= 0

Therefore, the rate at which the searchlight is rotating is given by the derivative of angle theta at time t=5, which we can find using trigonometry:

tan(theta) = BC / 20

= 1/10

Differentiating both sides with respect to time, we get:

sec^2(theta) * d/dt (theta) = -BC / 20^2 * d/dt(BC)

= -1/100 * 2

Substituting theta = arctan(1/10) and d/dt(BC) = 2, we get:

d/dt (theta) = -2*sec^2(arctan(1/10)) / 100

≈ -0.005 rad/s

Therefore, the rate at which the searchlight is rotating when Sophie is at 10 ft from the point on the path closest to the searchlight is approximately -0.005 rad/s.

The half-life of the radioactive element is approximately 315.16 days and It will take approximately 61.84 days for a sample of 100 mg to decay to 88 mg.

(a) To determine the half-life of the radioactive element, we can use the fact that the radioactivity decreases by 45 percent in 300 days.

Since the half-life is the time it takes for the radioactivity to decrease by half, we can set up the equation:

0.45 = (1/2)^(300/h),

where 'h' represents the half-life we are trying to find.

To solve for 'h', we can take the logarithm of both sides with base 1/2:

log(0.45) = (300/h) * log(1/2).

Rearranging the equation, we have:

h = 300 / (log(0.45) / log(0.5))

≈ 315.16 days (rounded to two decimal places)

(b) To determine how long it will take for a sample of 100 mg to decay to 88 mg, we can use the concept of exponential decay. The decay follows the equation:

y = a * (1/2)^(t/h),

where 'y' is the final amount, 'a' is the initial amount, 't' is the time passed, and 'h' is the half-life.

Substituting the given values, we have:

88 = 100 * (1/2)^(t/h).

To solve for 't', we can rearrange the equation:

t = h * log(88/100) / log(1/2)

≈ 61.84 days (rounded to two decimal places).

To determine if the function f(z) = 1/[tex](1-z)^2[/tex] is complex differentiable at z = 0, we need to check if the limit of the difference quotient exists as z approaches 0. Let's compute the difference quotient:

f'(z) = lim (h→0) [f(z+h) - f(z)]/h

Substituting the function f(z) = 1/[tex](1-z)^2[/tex], we get:

f'(z) = lim (h→0) [tex][(1/(1-(z+h))^2 - 1/(1-z)^2][/tex]/h

Simplifying the expression, we obtain:

f'(z) = lim (h→0)[tex][(1/(1-2z-h+z^2))^2 - (1/(1-z))^2][/tex]/h

Using algebraic manipulations and the limit properties, we find that the limit of the difference quotient exists and is equal to 2/[tex](1-z)^3[/tex]. Therefore, f(z) is complex differentiable at z = 0.

Now, let's find its power series expansion. We can express f(z) as a geometric series by using the formula 1/(1-x) = Σn=0 to ∞ x^n. Plugging in x = z^2 into this formula, we obtain:

f(z) =[tex]1/(1-z^2) = Σn=0 to ∞ (z^2)^n = Σn=0 to ∞ z^(2n)[/tex]

The ODE for which f1(x) = e^x and f2(x) = e^(2x) are solutions is 0 = 0, which is an identity and does not represent a meaningful ODE.

To find the ordinary differential equation (ODE) for which f1(x) = e^x and f2(x) = e^(2x) are solutions, we can use the fact that if f1(x) and f2(x) are solutions to an ODE, then their linear combination c1*f1(x) + c2*f2(x) is also a solution for any constants c1 and c2.

Let's find the ODE by considering the derivatives of f1(x) and f2(x).

f1(x) = e^x, taking the derivative gives:

f1'(x) = d/dx(e^x) = e^x.

f2(x) = e^(2x), taking the derivative gives:

f2'(x) = d/dx(e^(2x)) = 2e^(2x).

Now, let's find the constants c1 and c2 such that c1*f1(x) + c2*f2(x) satisfies an ODE.

c1*f1(x) + c2*f2(x) = c1*e^x + c2*e^(2x).

To find the ODE, we differentiate c1*f1(x) + c2*f2(x) and equate it to zero.

(d/dx)(c1*f1(x) + c2*f2(x)) = c1*e^x + c2*2e^(2x) = 0.

For this equation to hold for all x, the coefficients of the exponential terms must be zero. Therefore, we have the following system of equations:

Based on the sample of 67 LMC students, we have the proportion:

49 (number of students with family, job, and school) / 67 (sample size) = x (number of students with family, job, and school) / 7560 (total number of LMC students).

We can solve this proportion by cross-multiplying and then solving for "x":

49 * 7560 = 67 * x

x = (49 × 7560) / 67 ≈ 5652

Therefore, using the proportion, we estimate that approximately 5652 out of the total 7560 LMC students have a family, job, and go to school.

To find the extremizer point that minimizes the expression x₂ – (x₁ – 2)³ + 3, subject to the constraint x₂ ≥ 1, we need to evaluate the given expression for different values of x₁ and x₂. The extremizer point that satisfies the constraint and minimizes the expression is x = [1,2].

To determine the extremizer point, we need to consider the given expression x₂ – (x₁ – 2)³ + 3 and the constraint x₂ ≥ 1.
Let's evaluate the expression for different values of x₁ and x₂:For x = [1,2]: x₂ – (x₁ – 2)³ + 3 = 2 – (1 – 2)³ + 3 = 2 – (-1)³ + 3 = 2 + 1 + 3 = 6
For x = [2,2]: x₂ – (x₁ – 2)³ + 3 = 2 – (2 – 2)³ + 3 = 2 – 0 + 3 = 5
For x = [0,2]: x₂ – (x₁ – 2)³ + 3 = 2 – (0 – 2)³ + 3 = 2 – (-2)³ + 3 = 2 + 8 + 3 = 13
For x = [0,1]: x₂ – (x₁ – 2)³ + 3 = 1 – (0 – 2)³ + 3 = 1 – (-2)³ + 3 = 1 + 8 + 3 = 12
For x = [1,1]: x₂ – (x₁ – 2)³ + 3 = 1 – (1 – 2)³ + 3 = 1 – (-1)³ + 3 = 1 + 1 + 3 = 5
For x = [2,1]: x₂ – (x₁ – 2)³ + 3 = 1 – (2 – 2)³ + 3 = 1 – 0 + 3 = 4

Among these values, the extremizer point that minimizes the expression and satisfies the constraint x₂ ≥ 1 is x = [1,2], which evaluates to 6. Therefore, the correct answer is O x = [1,2].

To approximate the integral using composite Simpson's rule, we divide the interval [a, b] into n subintervals, where n is an even number. The formula for composite Simpson's rule is:

∫[a,b] f(x) dx ≈ (h/3) [f(x₀) + 4f(x₁) + 2f(x₂) + 4f(x₃) + 2f(x₄) + ... + 4f(xₙ₋₁) + f(xₙ)]

Given n = 3, we have four equally spaced points x₀, x₁, x₂, x₃, and the interval [a, b] can be divided into three subintervals. Applying composite Simpson's rule:

∫[a,b] cos(x³ + 10) dx ≈ (h/3) [f(x₀) + 4f(x₁) + 2f(x₂) + 4f(x₃) + f(x₄)]

Using the given approximation formula, we have:

∫[a,b] cos(x³ + 10) dx ≈ (1/3) [cos(x₀³ + 10) + 4cos(x₁³ + 10) + 2cos(x₂³ + 10) + 4cos(x₃³ + 10) + cos(x₄³ + 10)]

Calculating the values for each term using x₀, x₁, x₂, x₃, and x₄, and substituting them into the formula, we find:

∫[a,b] cos(x³ + 10) dx ≈ 1.01259

Therefore, the correct answer is: O 1.01259.

The absolute maximum value of f(x) = x^3 - 12x on the interval [-3, 3] is 16, and the absolute minimum value is -16.

To find the absolute extreme values of the function f(x) = x^3 - 12x on the interval [-3, 3], we need to evaluate the function at its critical points and endpoints, and then compare the function values.

Find the critical points:

To find the critical points, we need to find the values of x where the derivative of f(x) is equal to zero or undefined.

First, let's find the derivative of f(x):

f'(x) = 3x^2 - 12

Setting f'(x) equal to zero and solving for x:

3x^2 - 12 = 0

x^2 - 4 = 0

(x - 2)(x + 2) = 0

So we have two critical points: x = -2 and x = 2.

Evaluate the function at the critical points and endpoints:

Now we need to evaluate the function f(x) at the critical points and the endpoints of the interval [-3, 3].

For x = -3:

f(-3) = (-3)^3 - 12(-3) = -27 + 36 = 9

For x = -2:

f(-2) = (-2)^3 - 12(-2) = -8 + 24 = 16

For x = 2:

f(2) = (2)^3 - 12(2) = 8 - 24 = -16

For x = 3:

f(3) = (3)^3 - 12(3) = 27 - 36 = -9

Compare the function values:

Now we compare the function values at the critical points and endpoints to determine the absolute extreme values.

The function values are:

f(-3) = 9

f(-2) = 16

f(2) = -16

f(3) = -9

The maximum value is 16, which occurs at x = -2.

The minimum value is -16, which occurs at x = 2.

Therefore, the absolute maximum value of f(x) = x^3 - 12x on the interval [-3, 3] is 16, and the absolute minimum value is -16.

The positions are 3, 7, or 13 from 407

To determine if 407 is an N position under the normal game rule, we need to consider all possible moves from this number. Since the set is {3, 7, 13}, we can subtract either 3, 7, or 13 from 407. Let's examine each option:

Subtracting 3 from 407:

This yields 404. Now, we need to consider the possible moves from 404. In this case, we can subtract either 3, 7, or 13. If we subtract 3, we get 401, and so on.

Subtracting 7 from 407:

This results in 400. Similar to before, we need to consider the possible moves from 400.

Subtracting 13 from 407:

This gives us 394. Again, we need to consider the possible moves from 394.

At each step, we continue exploring the possible moves until we reach a point where no valid move can be made. This process is known as game tree traversal.

The difference quotient for the given function f(x) = x² - 5x, specifically for the expression f(-2+h) - f(-2)/h, is (h² + 4h)/h.

The difference quotient for the function f(x) = x² - 5x, specifically for the expression f(-2+h) - f(-2)/h, can be calculated as follows:

First, we substitute the values into the function:

f(-2 + h) = (-2 + h)² - 5(-2 + h)

f(-2) = (-2)² - 5(-2)

Next, we simplify the expressions:

f(-2 + h) = h² + 4h + 4 - (-10 + 5h)

f(-2) = 4 + 10

Now, we can subtract the two simplified expressions:

f(-2 + h) - f(-2) = h² + 4h + 4 - (-10 + 5h) - (4 + 10)

Simplifying further, we have:

f(-2 + h) - f(-2) = h² + 4h + 4 + 10 - 4 - 10

f(-2 + h) - f(-2) = h² + 4h

Finally, we divide the expression by h:

(f(-2 + h) - f(-2))/h = (h² + 4h)/h

The difference quotient for f(-2+h) - f(-2)/h is (h² + 4h)/h.

In summary, the difference quotient for the given function f(x) = x² - 5x, specifically for the expression f(-2+h) - f(-2)/h, is (h² + 4h)/h.

This represents the rate of change of the function as h approaches 0, indicating the slope of the function at a particular point.

The sum Sn is equal to n/2 times the sum of the first and last term, which is (3n - 3)/2.

The sum of the arithmetic series 0 + 3 + 6 + ... + (3n - 3) can be calculated using the formula for the sum of an arithmetic series.

In an arithmetic series, where each term differs from the previous term by a constant difference, we can find the sum of the series by using the formula Sn = n/2(a + l), where Sn is the sum, n is the number of terms, a is the first term, and l is the last term.

In this case, the first term a is 0, and the last term l is (3n - 3). Substituting these values into the formula, we get Sn = n/2(0 + (3n - 3)) = n/2(3n - 3) = (3n^2 - 3n)/2.

Therefore, the sum of the series 0 + 3 + 6 + ... + (3n - 3) is (3n^2 - 3n)/2
