Answer: In order to solve for x, we will have to use the logarithmic properties to isolate x.

f(x) = 3 - 4 In (x-2)

To solve for x, we will have to get x alone on one side of the equation by using the logarithmic property that logb(a^c) = c*logb(a).

4 In (x-2) = 3

In (x-2) = 3/4

To find x, we will raise e to the power of both sides

x-2 = e^(3/4)

x = e^(3/4) + 2

So the solution of x is e^(3/4) + 2

It's important to notice that the natural logarithm (ln) and log base e (In) are same and the solution is valid for both.

5. Check that the population size is more than 10 times the sample size.

6. Check that the population distribution is approximately normal.

A one-sample z-test for a population proportion is used to evaluate the difference between a sample proportion and a population proportion. Before conducting the test, it is important to check for independence, which is done by ensuring that certain conditions are met. First, npo > 10 and n(1-Po) > 10 must be true for both the sample and population proportions, Po. Additionally, each sample proportion must be less than or equal to 0.5, the sample size must be more than 10 times the population size, and the population size must be more than 10 times the sample size. Lastly, the population distribution must be approximately normal. These conditions must be met in order for the test to be valid and reliable. If any of these conditions are not met, the test results may be inaccurate.

The evaluation of the velocity function, v(t) = cos((π/6)·t) for the interval 0 ≤ t ≤ 12, th obtain the position and acceleration is as follows;

(a) The particle is moving to the left when 3 < t < 9

(b) The total distance is; [tex]\int\limits^6_0 {cos(\frac{\pi}{6}\cdot t) } \, dt[/tex]

(c) a(t) ≈ -0.453

(d) x(4) ≈ -0.346

Acceleration is the rate at which the velocity of the object changes.

The function for the velocity of the particle is presented as follows;

v(t) = cos((π/6)·t)

The position of the particle at time, t = 0 is x = -2

(a) When the particle is moving to the left, the velocity is negative

The value of cos(θ) is negative for π/2 < θ < 1.5·π

The range of values of θ = ((π/6)·t), for 0 ≤ t ≤ 2, are;

((π/6) × 0) ≤ θ ≤ ((π/6) × 12), from which we get;

0 ≤ θ ≤ (2·π)

When π/2 = (π/6)·t, we get;

t = (π/2)/(π/6) = 3

When 1.5·π = (π/6)·t, we get;

t = (1.5·π)/(π/6) = 9

The particle is moving to the left between time t = 3 and time t = 9, which can be expressed as follows;

(b) The total distance traveled by the particle from time t = 0 to time t  = 6 is presented using the definite integral as follows;

(c) Acceleration, a, is the rate of change of the velocity, therefore, the acceleration is the derivative of the velocity function, which can be obtained as follows;

[tex]a(t) =\frac{d}{dt} {cos(\frac{\pi}{6}\cdot t) } = -\frac{\pi}{6} \cdot sin(\frac{\pi}{6} \cdot t)[/tex]

[tex]a(t) = -\frac{\pi}{6} \cdot sin(\frac{\pi}{6} \cdot t)[/tex]

At time t = 4, we get;

[tex]a(4) = -\frac{\pi}{6} \cdot sin(\frac{\pi}{6} \times 4) = -\frac{\sqrt{3} \cdot \pi}{12}[/tex]

(d) The position of the particle at time t = 4, can be obtained by adding the the position of the particle at time t = 4 to the total distance covered between time t = 0 and time t = 4 as follows;

[tex]\int\limits^4_0 {cos(\frac{\pi}{6}\cdot t) } \, dt =[ \frac{6}{\pi}\cdot {sin(\frac{\pi}{6}\cdot t) }]^4_0[/tex]

[tex][ \frac{6}{\pi}\cdot {sin(\frac{\pi}{6}\cdot t) }]^4_0 = [ \frac{6}{\pi}\cdot {sin(\frac{\pi}{6}\times 4) }] - [ \frac{6}{\pi}\cdot {sin(\frac{\pi}{6}\times 0) }]=\frac{3\cdot \sqrt{3} }{\pi}[/tex]

B. (A UBUC)' is the empty set.

Both options A and B express that the complement of the union of the sets A, B, and C is the empty set. The complement of a set is the set of all elements that are not in that set. The union of sets is the set of all elements that are in at least one of the sets.

When taking the union of A, B, and C all the elements in U are included, so there is no element that is not in the set, making the complement of the union of A,B,C is an empty set.

The model's graph, y = 10770/x2 - 0.37, 5 x 100 demonstrates that the resistance will be about halved when the wire's diameter is doubled. This is brought on by the inverse square relationship between wire resistance and diameter.

1. Graph the model y = 10770/x² - 0.37, 5 ≤ x ≤ 100 using a graphing utility.

2. Find the resistance when x is 5.

y = 10770/5² - 0.37 = 2104.1 ohms

3. Find the resistance when x is 10.

y = 10770/10² - 0.37 = 526 ohms

4. Divide 2104.1 by 526 to find the factor by which the resistance is changed when the diameter of the wire is doubled.

2104.1/526 = 4

The graph of the model y = 10770/x² - 0.37, 5 ≤ x ≤ 100 shows that the resistance of the wire decreases as the diameter of the wire increases. Doubling the diameter of the wire will roughly halve the resistance, as can be seen by comparing the resistance when x is 5 (2104.1 ohms) to the resistance when x is 10 (526 ohms). Thus, the resistance is changed by a factor of 4 when the diameter of the wire is doubled.

Answer:

A line that is perpendicular to the line y=-2x+1 will have a slope that is the negative reciprocal of -2, which is 1/2.

The equation of a line in point-slope form is:

y - y1 = m(x - x1)

Where m is the slope of the line, and (x1, y1) is a point on the line.

Given that the point (-4,3) lies on the line, we can substitute those values for x1 and y1:

y - 3 = 1/2(x + 4)

Which is the equation of a line that is perpendicular to y=-2x+1 that passes through the point (-4,3).

Alternatively, you can also write the equation of a line in slope-intercept form y = mx + b,

The slope of a line perpendicular to y=-2x+1 is 1/2, therefore m = 1/2

We can substitute the point (-4,3) in the equation y = mx + b,

3 = (1/2)(-4) + b

b = 3.5

Therefore the equation of the line is y = 1/2x + 3.5

In triangle XYZ,

As lengths of two sides XYZ are 23 and 48 inches

The range of the third side can be computed when we already know the two sides of the triangle.

If subtracting 48 - 23, the 3rd side would have to be more than 25. Else 3rd side can not be made as two smaller legs will not meet.

and If adding 48 + 23 , the 3rd side would have to be less than 61. Else 3rd side will reach further than the other two sides could reach.

Therefore, the length of side XZ should be greater than 25 and lesser than 61.

The length of missing side is 39.

Pythagoras theorem is a mathematical statement that states that in a right triangle, the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the two other sides (the legs).

It can be expressed as a2 + b2 = c2, where a and b are the two legs of the triangle and c is the hypotenuse. The theorem is named after the ancient Greek mathematician Pythagoras, who is believed to have discovered it.

Pythagoras theorem is an important concept in geometry, and is used to calculate the length of the hypotenuse in a right triangle when the lengths of the other two sides are known.

It can also be used to determine the lengths of the other two sides when the length of the hypotenuse is known. In addition, it can be used to find the angles of a right triangle when the lengths of the sides are known.

Pythagoras theorem has many applications in everyday life. For example, it can be used to calculate the height of a building, or the distance between two points.

It can also be used in carpentry, engineering, and architecture to measure distances and angles. In addition, it can be used in trigonometry to find the values of trigonometric functions.

Finally, it can be used in navigation to calculate distances and angles.

Let c be the length of missing side,

According to Pythagoras theorem,

a² + b² = c²

36² + 15² = c²

c = √1521

c = 39

So, the length of missing side is 39.

So, the two balls are located on the same plane, the x-y plane, with the baseball at <3,5,0>m and the tennis ball at <-3,-1,0>m, with the vector pointing from baseball to the tennis ball is <-6,-6,0>m.

The position vector of the baseball is <3,5,0>m. The position vector of the tennis ball is <-3,-1,0>m.

The position vector of the tennis ball relative to the baseball is the vector pointing from the baseball to the tennis ball and it is calculated by subtracting the position vector of the baseball from the position vector of the tennis ball: <-3,-1,0>m - <3,5,0>m = <-6,-6,0>m

So the two balls are located on the same plane, the x-y plane, with the baseball at <3,5,0>m and the tennis ball at <-3,-1,0>m, with the vector pointing from baseball to the tennis ball is <-6,-6,0>m.
