So, median = 78

By using  Fundamental Theorem of Calculus, we find the derivative of the function g(x) = In { sqrt( t + t^3)dt } limit from x to 0 is  ln(sqrt(x + x^3)).  The derivative of the function g(x) = { In (1+t^2) dt} where limit are from x to 1 is  ln(1 + x^2).

The Fundamental Theorem of Calculus, which states that if a function is defined as the definite integral of another function, then its derivative is equal to the integrand evaluated at the upper limit of integration.

So, applying this theorem, we have:

g'(x) = d/dx [∫x_0 ln(sqrt(t + t^3)) dt]

= ln(sqrt(x + x^3)) * d/dx (x) - ln(sqrt(0 + 0^3)) * d/dx (0)

= ln(sqrt(x + x^3))

Therefore, g'(x) = ln(sqrt(x + x^3)).

Using the Fundamental Theorem of Calculus, we have:

g'(x) = d/dx [∫1_x ln(1 + t^2) dt]

= ln(1 + x^2) * d/dx (x) - ln(1 + 1^2) * d/dx (1)

= ln(1 + x^2)

Therefore, g'(x) = ln(1 + x^2).

Answer:

1. $5

2. $1 per mile

3.y=x+5

Step-by-step explanation:

1. If you look at the graph you can see that the cost for 0 miles with the Green Cab is $5

2.If you look at the graph, for each mile traveled, the cost is $1

3. Since for each increase 1 increase in x, y increases by the same amount, the slope is 1

y=mx+b is the slope intercept form

m=slope

b=y intercept

since we know the slope is 1 we can put it in

y=1x+b

=y=x+b

to find the y intercept we can look at the graph and see what y equals when x is 0.

the y intercept is (0,5)

we can put that in so the equation in slope intercept form is

The point (9, -7) is the only solution to the system of linear inequalities given.

To determine which point would be a solution to the system of linear inequalities, let's substitute the given points into the inequalities and see which point satisfies both inequalities.

The system of linear inequalities is:

y > -4x + 6

y > (1/3)x - 7

Let's test each given point:

For the point (9, -7):

Substituting the values into the inequalities:

-7 > -4(9) + 6

-7 > -36 + 6

-7 > -30 (True)

-7 > (1/3)(9) - 7

-7 > 3 - 7

-7 > -4 (True)

Since both inequalities are true for the point (9, -7), it is a solution to the system of linear inequalities.

For the point (-12, -2):

Substituting the values into the inequalities:

-2 > -4(-12) + 6

-2 > 48 + 6

-2 > 54 (False)

-2 > (1/3)(-12) - 7

-2 > -4 - 7

-2 > -11 (False)

Since both inequalities are false for the point (-12, -2), it is not a solution to the system of linear inequalities.

For the point (12, 1):

Substituting the values into the inequalities:

1 > -4(12) + 6

1 > -48 + 6

1 > -42 (True)

1 > (1/3)(12) - 7

1 > 4 - 7

1 > -3 (True)

Since both inequalities are true for the point (12, 1), it is a solution to the system of linear inequalities.

For the point (-12, -7):

Substituting the values into the inequalities:

-7 > -4(-12) + 6

-7 > 48 + 6

-7 > 54 (False)

-7 > (1/3)(-12) - 7

-7 > -4 - 7

-7 > -11 (True)

Since one inequality is true and the other is false for the point (-12, -7), it is not a solution to the system of linear inequalities.

A probability model consists of the sample space and the way to assign probabilities. The sample space is the collection of all possible outcomes of a random experiment.  It can be finite, countably infinite, or uncountably infinite.

A probability model is a way of assigning probabilities to events in the sample space.The probability of an event is a measure of the likelihood that the event will occur. The probability of an event is always between 0 and 1, inclusive. A probability of 0 means that the event will never occur, while a probability of 1 means that the event is certain to occur. If an event has a probability of 0.5, then it is just as likely to occur as not to occur.The probability of an event can be calculated using different methods, depending on the type of experiment. For example, if the experiment is a coin toss, then the probability of getting heads is 0.5, and the probability of getting tails is also 0.5. If the experiment is rolling a six-sided die, then the probability of rolling a 1 is 1/6, the probability of rolling a 2 is 1/6, and so on.In summary, a probability model consists of the sample space and the way to assign probabilities. It is a mathematical framework used to quantify uncertainty in various fields such as statistics, physics, economics, and engineering. The probability of an event is a measure of the likelihood that the event will occur and is always between 0 and 1, inclusive.

Complement of set A is the set of all elements in the universal set that are not in the set .

If there is a subset of the universal set (U) called A, then the complement of set A, denoted by the symbol A', is different from the elements of set A and contains the elements of the universal set but not the elements of set A.

In this case, A' = x U: x A.

In other words, the complement of a set A is the difference between the universal set and set A.

For example: U = {1, 2, 3, 5, 7, 9, 15 ,14, 13}, A = {1, 2, 3, 5,7,9}, find the complement of A.

A' = U - A = {1, 2, 3, 5, 7, 9, 15,14,13} - {1, 2, 3, 5,7,9} = {15,14, 13}

A set that contains items from all related sets, without any repetition of elements, is known as a universal set (often symbolised by the letter U). If A and B are two sets, for example, A = 1, 2, 3 and B = 1, a, b, c, then U = 1, 2, 3, a, b, c is the universal set that these two sets belong to.

The distance between the yacht from the ship is about 33.6 km.

Step-by-step explanation:

The diagram is attached below.

Point A is the shipe, Point B is the tugboat, and Point C is the yacht.

Since the tugboat is 28 km away, and the scale being used is 1 cm : 4 km, the tugboat is 7 cm away from the ship at a 210° bearing on the diagram.

Likewise, the yacht is 6 cm away from the tugboat at a 210° bearing.

To find the distance between the yacht to the ship, we need to

yacht to the ship, we need to determine the value of x.

To do so, we can use the Law of Cosines:

b²a² + c²2ac cos(B) =

First, we need to determine ZB.

A has a bearing of 210°. 180° is covered by QI and IV. So, the small angle in QIII is 30°.

By Alternate Interior Angles, the angle in QI (inside the triangle) of Point B must also be 30°.

And since Point B has a bearing of 310°, 270° is covered in total by QI, QIV, and QIII. So, 40° is left in QII.

Therefore, 50° is the measure of the angle in QIII within the triangle of Point B.

Thus, ZB measures 50° + 30° = 80°.

So, ZB measures 80°. We also know that a = 6 and c= 7. Substitute:

b² = (6)² + (7)² - 2(6)(7) cos(80)

Simplify and take the square root of both sides. So:

b = √85-84 cos(80)

Approximate using a calculator:

b = 8.3912... ≈ 8.39 cm

Since 1 cm: 4km, to find the distance in km, we simply need to multiply by four. So:

⇒b= 4(8.3912...) = 33.5651 ≈

33.6 km

The distance between the yacht from the ship is about 33.6 km.

Step-by-step explanation:

hope it helps you itz admirer

The distance of the yacht from the ship will be 33.6km.

From the information given, the tugboat is 28 km away at a bearing of 210°, and a yacht is 24 km from the tugboat at a bearing of 310°.

In this case, we can use the law of cosine formula to solve it and it will be:

b²= a² + c²2ac cos(B)

b² = 6² + 7² - (2 × 6 × 7)cos80°

b = 8.39

Therefore, since a scale of 1 cm : 4 km is used, the distance will be:
