Step-by-step explanation:

Answer:

\(\textsf{B)} \quad f(x) = 5 \sin (16x) + 7}\)

Step-by-step explanation:

The sine function is periodic, meaning it repeats forever.

\(\boxed{f(x) = A \sin (B(x + C)) + D}\)

where:

Given values:

Calculate the value of B:

\(\dfrac{2\pi}{B}=\dfrac{\pi}{8}\implies 16\pi=B\pi\implies B=16\)

Substitute the values of A, B C and D into the standard formula:

\(f(x) = 5 \sin (16(x + 0)) + 7\)

\(f(x) = 5 \sin (16x) + 7\)

Therefore, the sine function with an amplitude of 5, a period of π/8, and a midline at y = 7 is:

\(\Large\boxed{\boxed{f(x) = 5 \sin (16x) + 7}}\)

According to the image, the missing angle is 100°.

When we want to calculate an angle of a triangle we must take into account the following information:

If we know the value of two angles (angles 2 and 3) of the triangle we must add the measure of the two angles we know.

Now we must subtract the sum total of the two known angles from 180°.

So the value of angle 1 would be 100°. Additionally, 180° is a rule that we must follow, because the angles of a triangle must always add up to 180°.

The time spent higher than 26 meters above the ground is 0.42 minutes. Answer: 0.42

A Ferris wheel is 30 meters in diameter and boarded from a platform that is 4 meters above the ground.

The six o'clock position on the Ferris wheel is level with the loading platform.

The wheel completes 1 full revolution in 2 minutes.

We have to find how many minutes of the ride are spent higher than 26 meters above the ground.

So, let's start with some given data,Consider the height of a person at the six o'clock position = 4 meters

So, the height of a person at the highest point = 4 + 15 = 19 meters (since the diameter is 30 meters, the radius will be 15 meters)

Also, the height of a person at the lowest point = 4 - 15 = -11 meters

Therefore, the Ferris wheel completes one cycle from the lowest point to the highest point and back to the lowest point.

So, the total distance travelled will be = 19 + 11 = 30 meters.

Also, we are given that the wheel completes 1 full revolution in 2 minutes.

We need to calculate the time spent higher than 26 meters above the ground.

So, the angle between the 6 o'clock position and 2 o'clock position will be equal to the angle between the 6 o'clock position and the highest point.

This angle can be calculated as follows:

Angle = Distance travelled by the Ferris wheel / Circumference of the Ferris wheel * 360 degrees

Angle = 30 / (pi * 30) * 360 degrees

Angle = 360 degrees / pi

= 114.59 degrees

So, the total angle between the 6 o'clock position and the highest point is 114.59 degrees.

Now, we need to find out how much time is spent at an angle greater than 114.59 degrees.

This can be calculated as follows:

Time = (Angle greater than 114.59 degrees / Total angle of the Ferris wheel) * Total time taken

Time = (180 - 114.59) / 360 * 2 minutes

Time = 0.42 minutes

Answer:

\(h = 3.5\)

\(w = 7\)

\(l = 7\)

Step-by-step explanation:

Given

\(Volume = 171.5ft^3\)

Required

The dimension that requires least material

The volume is:

\(Volume = lwh\)

Where:

\(l \to length\)

\(w \to width\)

\(h \to height\)

So, we have:

\(171.5 = lwh\)

Make l the subject

\(l = \frac{171.5}{wh}\)

The surface area (A) of an open-top rectangular tank is:

\(A = lw + 2lh + 2wh\)

Substitute: \(l = \frac{171.5}{wh}\)

\(A = \frac{171.5}{wh} * w + 2*\frac{171.5}{wh}*h + 2wh\)

\(A = \frac{171.5}{h} + 2*\frac{171.5}{w} + 2wh\)

\(A = \frac{171.5}{h} + \frac{343}{w} + 2wh\)

Rewrite as:

\(A = 171.5h^{-1} + 343w^{-1} + 2wh\)

Differentiate with respect to h and w

\(A_h = -171.5h^{-2} +2w\)

\(A_w = -343w^{-2} +2h\)

Equate both to 0

\(-171.5h^{-2} +2w=0\)

Make w the subject

\(2w = 171.5h^{-2}\)

Divide by 2

\(w = 85.75h^{-2}\)

\(-343w^{-2} +2h = 0\)

Make h the subject

\(2h = 343w^{-2}\)

Divide by 2

\(h = 171.5w^{-2}\)

\(h = \frac{171.5}{w^2}\)

Substitute \(w = 85.75h^{-2}\) in \(h = \frac{171.5}{w^2}\)

\(h = \frac{171.5}{(85.75h^{-2})^2}\)

\(h = \frac{171.5}{85.75^2*h^{-4}}\)

\(h = \frac{2}{85.75*h^{-4}}\)

Multiply both sides by \(h^{-4}\)

\(h^{-4} * h = \frac{1}{85.75*h^{-4}} * h^{-4}\)

\(h^{-3} = \frac{2}{85.75}\)

Rewrite as:

\(\frac{1}{h^3} = \frac{2}{85.75}\)

Inverse both sides

\(h^3 = 85.75/2\)

\(h^3 = 42.875\)

Take cube roots

\(h = 3.5\) ---- height

Recall that: \(w = 85.75h^{-2}\)

\(w = 85.75 * 3.5^{-2}\)

\(w = 7\) --- width

Recall that: \(l = \frac{171.5}{wh}\)

\(l = \frac{171.5}{3.5 * 7}\)

\(l = 7\) --- length

The only solution for the equation 8 tan^2 θ = 3 cos^2 θ in the given Range is θ ≈ 19.47 degrees.

a) We are given the equation 8 tan θ = 3 cos θ.

Dividing both sides of the equation by cos θ, we have:

8 tan θ / cos θ = 3

Using the identity tan θ = sin θ / cos θ, we can substitute it into the equation:

8 (sin θ / cos θ) / cos θ = 3

Simplifying further, we get:

8 sin θ / cos^2 θ = 3

Now, multiplying both sides of the equation by cos^2 θ, we have:

8 sin θ = 3 cos^2 θ

Using the identity cos^2 θ = 1 - sin^2 θ, we can substitute it into the equation:

8 sin θ = 3(1 - sin^2 θ)

Expanding the equation, we get:

8 sin θ = 3 - 3 sin^2 θ

Rearranging the terms, we have:

3 sin^2 θ + 8 sin θ - 3 = 0

Therefore, we have successfully shown that the equation can be rewritten in the form 3 sin^2 θ + 8 sin θ - 3 = 0.

b) Now, let's solve the equation 3 sin^2 θ + 8 sin θ - 3 = 0.

To solve the quadratic equation, we can use factoring, quadratic formula, or other appropriate methods.

In this case, the equation factors as:

(3 sin θ - 1)(sin θ + 3) = 0

Setting each factor equal to zero, we have two equations:

3 sin θ - 1 = 0    or    sin θ + 3 = 0

For the first equation, solving for sin θ, we get:

3 sin θ = 1

sin θ = 1/3

Taking the inverse sine (sin^-1) of both sides, we find:

θ = sin^-1(1/3) ≈ 19.47 degrees (to 2 decimal places)

For the second equation, solving for sin θ, we have:

sin θ = -3

Since the range of sine is between -1 and 1, there are no solutions for this equation in the given range (0 ≤ θ ≤ 90 degrees).

Therefore, the only solution for the equation 8 tan^2 θ = 3 cos^2 θ in the given range is θ ≈ 19.47 degrees.

The key features of this quadratic relation y = -3x² - 24x - 36 include;

In Mathematics and Geometry, the graph of a quadratic function would always form a parabolic curve because it is a u-shaped.

Since the leading coefficient (value of a) in the given quadratic function y = -3x² - 24x - 36 is negative 16, we can logically deduce that the parabola would open downward and the x-intercept (roots) is given by the ordered pair (-6, 0) and (-2, 0).

When x = 0, the y-intercept can be determined as follows;

y = -3x² - 24x - 36

y = -3(0)² - 24(0) - 36

y = -36

Axis of symmetry, Xmax = -b/2a

Axis of symmetry, Xmax = -(-24)/2(-3)

Axis of symmetry, Xmax = -4

For the vertex, we have:

y(-4) = -3x² - 24x - 36

y(-4) = -3(-4)² - 24(-4) - 36

y(-4) = 12

In conclusion, the quadratic function has a maximum value at 12.

Step-by-step explanation:

A) First, you need to Combine Like Terms on the right side of the =

98-248 = -150

Now, you need to Isolate the variable by getting rid of the -178. What you do to one side, you must do the the other.

56a-178(+178) = -150(+178)

56a = 28

Finally, you must remove that 56 on the a. Since it stands for 56 x a, you must do the same you did with the -178 except with Division.

56a/56 = 28/56

a = 0.5

Answer:

DF

Explanation:

To know the order of the sides, we need to identify all three interior angles.

So, to know the missing angle, we will apply that the sum of all interior angles of a triangle is equal to 180°. It means that:

∠D + ∠E + ∠F = 180

∠D + 61 + 59 = 180

∠D + 120 = 180

∠D = 180 - 120

∠D = 60°

Now, the relation between every side and its opposite angle is proportional. It means that if the greatest angle is E, the longest side is the opposite one or DF.

So, the ordered angles and sides are:

∠E = 61° -----> DF

∠D = 60° -----> EF

∠F = 59° -----> DE

Therefore, the sides in the order form longest to shortest are:

Amplitude is the maximum displacement of a function on a graph.

Amplitude is the maximum displacement of a function on a graph. It refers to the maximum height or distance from the baseline of a wave or oscillation.

It is often used in physics and engineering to describe the strength or size of a signal, vibration, or wave. In simple terms, it can be thought of as the "peak-to-peak" distance of a waveform, or the height of the waveform above and below the baseline.

But the minimum displacement of a function on a graph would typically be referred to as the minimum value or the "valley" of the function.
