Function g(x) is function f(x) translated 3 units to the left and 2 units down.

Here we know that the function f(x) = (x − 2)³ is transformed to g(x) = (x + 1)³ − 2.

Remember that:

A vertical translation of N units is written as:

g(x) =f(x) + N

if N > 0, the translation is up.

If N < 0, the translation is down.

A horizontal translation of N units is written as:

g(x) =f(x) + N

if N > 0, the translation is left.

If N < 0, the translation is right.

Here we can see that:

g(x) = f(x + 3) - 2

Then we have a translation of 3 units to the right and 2 units downñ.

The rate of change for Modis building stairwell is 0.68 feet per step.

The speed formula can be defined as the rate at which an object covers some distance. Speed can be measured as the distance travelled by a body in a given period of time. The SI unit of speed is m/s.

Part A: In the Modis building, he climbs 22 steps for every 15 ft of horizontal travel.

Now, rate = 15/22

= 0.68 feet per step

In Sears Tower, he climbs 17 steps for every 7 ft of horizontal travel

Here, rate 7/17

= 0.41 feet per step

Part B: Sears Tower steps are easy to climb, because rate is lesser than Modis building steps.

Therefore, the rate of change for Modis building stairwell is 0.68 feet per step.

The spot on the shoreline is moving at a rate of about 1.764 feet per minute when it is 13 feet from the point on the shoreline closest to the lighthouse.

What is differentiation?

Differentiation is a mathematical operation that is used to find the rate at which a function changes. More specifically, it is the process of finding the derivative of a function.

The derivative of a function at a given point is a measure of how quickly the function is changing at that point. It gives the slope of the tangent line to the graph of the function at that point. The derivative can be thought of as the instantaneous rate of change of the function at that point.

Let's call the point on the shoreline closest to the lighthouse "P". We know that the distance from the spotlight to P is 130 feet, and we want to find the rate at which the distance from the spotlight to P changes when the spotlight is 13 feet from P.

To do this, we can use the chain rule to differentiate the distance formula with respect to time. Let's call the distance between the spotlight and P "d". Then:

                           d²= 130² + x²

Taking the derivative of both sides with respect to time gives:

                   2d * dd/dt = 0 + 2x * dx/dt

We can solve for dd/dt by plugging in the values we know:

130² + 13² = d²

d = [tex]\sqrt{(130^2 + 13^2)}[/tex] = 130.325 ft

2(130.325) * dd/dt = 2(13) * dx/dt

dd/dt = (13/130.325) * dx/dt

We know that the spotlight revolves at a rate of 281 rad/min, or 281/2π ≈ 44.7 revolutions per minute. Each revolution of the spotlight covers a distance of 2π * 130 feet, so its speed is:

(2π * 130 ft/rev) * (44.7 rev/min) = 18410.8 ft/min

To find dx/dt when x = 13, we need to find the angular velocity of the spotlight at that point. The spotlight makes one full revolution every 60/14 ≈ 4.29 seconds, so its angular velocity is:

2π radians/rev ÷ 4.29 s/rev = 1.47 radians/s

At any given moment, the angle between the spotlight and the line connecting the lighthouse and P is equal to the arctangent of x/130. When x = 13, this angle is:

arctan(13/130) ≈ 5.71°

The rate at which the angle is changing is equal to the angular velocity of the spotlight, so we can use the formula for the derivative of the arctangent to find dx/dt:

dx/dt = 130 * tan(5.71°) * (1.47 radians/s)

dx/dt ≈ 17.602 ft/min

Finally, we can substitute this value into the expression we found for dd/dt:

dd/dt = (13/130.325) * 17.602

dd/dt ≈ 1.764 ft/min

So the spot on the shoreline is moving at a rate of about 1.764 feet per minute when it is 13 feet from the point on the shoreline closest to the

To show that the wave function y=e^(b(x-vt)) is a solution of the linear wave equation (eq. 16.27), we need to plug the wave function into the equation and see if it satisfies the equation.

The linear wave equation (eq. 16.27) is given by:

∂^2y/∂x^2 = (1/v^2) ∂^2y/∂t^2

Plugging in the wave function y=e^(b(x-vt)) into the equation, we get:

∂^2(e^(b(x-vt)))/∂x^2 = (1/v^2) ∂^2(e^(b(x-vt)))/∂t^2

Taking the second derivative with respect to x, we get:

b^2 e^(b(x-vt)) = (1/v^2) ∂^2(e^(b(x-vt)))/∂t^2

Taking the second derivative with respect to t, we get:

b^2 e^(b(x-vt)) = (1/v^2) b^2 v^2 e^(b(x-vt))

Simplifying, we get:

b^2 e^(b(x-vt)) = b^2 e^(b(x-vt))

This shows that the wave function y=e^(b(x-vt)) satisfies the linear wave equation (eq. 16.27) and is therefore a solution of the equation.

The required equation represents the inverse function b(a), which takes the trapezoid's area is B(a) = a/6 - 9.

A trapezoid is a quadrilateral having two parallel bases and one set of other sides called as legs.

We have been given that the trapezoid's base is nine and its height is twelve.

As an outcome, 'b' is the base's parallel side.

The function that represents the trapezoid's area is given by:

A(b) = [12(b + 9)]/2

Let's consider A(b) = a

Then, a =  [12(b + 9)]/2

Now solving for b, we get

2a = 12(b + 9)

a = 6(b + 9)/2

a = 6b + 54

6b = a - 54

b = (a - 54)/6

b = a/6 - 9

Assuming that the length of the side parallel to the base 'b' = B(a), the equation will be:

B(a) = a/6 - 9

Thus, the correct answer would be option A. B(a) = a/6 - 9.

The probability that all four of the selected bolts are torqued to the proper limit is approximately 0.28.

To calculate the probability that all four of the selected bolts are torqued to the proper limit, we need to find the number of combinations of 4 bolts out of 20 that have been torqued to the proper limit.

Let's call the number of proper bolts n = 20 - 5 = 15.

The number of combinations of 4 proper bolts out of 15 is given by the binomial coefficient nCk, where n is the number of bolts and k is the number of bolts selected.

nCk = n! / (k! (n - k)!).

So, the number of combinations of 4 proper bolts out of 15 is:

15C4 = 15! / (4! (15 - 4)!) = 15! / (4! 11!) = 1365.

Therefore, the probability of selecting all 4 proper bolts out of 20 is:

P = number of combinations of 4 proper bolts / number of combinations of 4 bolts = 1365 / 20C4 = 1365 / 4845 = 0.28

So, the probability that all four of the selected bolts are torqued to the proper limit is approximately 0.28.

A line of reflection in a triangle can be any line that acts as a mirror image, such that the reflected image of the triangle is congruent to the original triangle.

This line is perpendicular to the plane of the triangle and bisects the angle between the two sides that are being reflected.

To be sure that each point was reflected across this line, we apply the reflection rule.

The reflection rule states that the distance from a point to the line of reflection is equal to the distance from its reflection to the line of reflection. This ensures that the reflected image of the triangle is congruent to the original triangle.

In an isosceles right triangle, two of its sides are congruent. This means that it satisfies the Angle-Side-Angle (ASA) congruence theorem. The ASA theorem states that if two triangles have two congruent angles and a congruent side between them, then the two triangles are congruent.

In addition to satisfying the ASA congruence theorem, an isosceles right triangle also satisfies the Pythagorean theorem. The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

Finally, the reflection of a triangle is considered a rigid motion, as it preserves the size and shape of the triangle.

Rigid motions do not change the lengths of the sides or the angles between them. They only change the position of the triangle in space. In the case of reflection, the triangle is flipped over the line of reflection, but its size and shape remain unchanged
