The equation that can be used to determine the number of people (x) who can go to the amusement park is:

207.50 = 5 + (33.75 × x).

To determine the number of people (x) who can go to the amusement park, we need to create an equation using the given information. We know that they have $207.50 to spend, parking costs $5, and each ticket costs $33.75 per person (including tax).

We can represent the total cost of the trip as the sum of the cost for parking and the cost of the tickets for x number of people. The equation would be:

Total Cost = Cost of Parking + (Cost of Tickets per Person × Number of People)

Since we know the total cost is $207.50, the cost of parking is $5, and the cost of tickets per person is $33.75, we can plug in these values:

207.50 = 5 + (33.75 × x)

This equation can be used to determine the value of the variable x, the number of people who can go to the amusement park. To find the value of x, simply solve the equation by isolating the variable x.

Answer:

  b. g(t) = 1.5 sin (π t) +3.5

Step-by-step explanation:

You want to choose the function that has the given graph.

At t = 0, the graph shows a value of 3.5. The sine of 0 is 0, so this eliminates choice A.

At t = 1/2, the graph shows a value of 5. The values given by the different formulas are ...

  b. g(1/2) = 1.5·sin(π/2) +3.5 = 5 . . . . . matches the graph

  c. h(1/2) = 1.5·sin(π) + 3.5 = 3.5 . . . . no match

  d. h(1/2) = 1.5·sin(π/4) +3.5 = 0.75√2 +3.5 . . . . no match

__

Additional comment

The horizontal distance for one period of the graph (from peak to peak, for example) is T = 2 seconds. If the sine function is sin(ωt), then the value of ω is ...

  ω = 2π/T = 2π/2 = π

This tells you the function g(t) = 1.5·sin(πt)+3.5 is the correct choice.

To emphasize the difference between the cost per doctor visit for each of the three plans, you can change the scale on the y-axis to either 0–100 or 25–40 and adjust the interval of the y-axis to count by 5s.

To emphasize the difference, you can consider the following adjustments to the graph:

1. Change the scale on the y-axis to 0–100. This adjustment will give a wider range for the costs, making it easier to see the differences between the three plans.

2. Alternatively, change the scale on the y-axis to 25–40. This change will focus more on the specific cost range that the three plans fall into, magnifying the differences between them.

3. Change the interval of the y-axis to count by 5s. This alteration will increase the number of increments on the y-axis, giving a more detailed view of the cost differences between the plans.

4. On the other hand, changing the interval of the y-axis to count by 20s might not be the best option. It will decrease the increments on y-axis and make it harder to visualize the cost differences between the plans.

The length of lm is 10 cm.

To find the length of lm, we need to use the fact that om and oj are both diameters of their respective circles. We can start by finding the radius of each circle:

- The radius of om is half of its diameter, so it's 34 cm.
- The radius of oj is half of its diameter, so it's 27 cm.

Next, we can use the fact that jk is perpendicular to lm to create a right triangle:

- One leg of the triangle is jk, which we know is 8 cm.
- The other leg is half of the difference between the radii of the two circles, since lm connects the two circles. That means the other leg is (34 - 27)/2 = 3.5 cm.

Now we can use the Pythagorean theorem to find the length of lm:

lm² = jk² + (radius difference/2)²
lm² = 8² + 3.5²
lm² = 70.25
lm = 10 cm

Answer:

274.78

Step-by-step explanation:

Let's call the original price "x".

We know that the price decreased by 31%, so the new price is

100% - 31% = 69% of the original price:

0.69x = 189.6

To solve for x, we can divide both sides by 0.69:

x = 189.6 / 0.69

Simplifying this expression, we get:

x ≈ 274.78

Therefore, the original price was approximately $274.78.

To evaluate the integral ∫(x^3+4x)/x^4+8x^2+1, we can use the substitution u = x^2 + 1. Then, du/dx = 2x, which means that dx = du/(2x). Substituting these into the integral, we get:

∫(x^3+4x)/x^4+8x^2+1 dx = ∫(1/u)(x^2+1)(x^3+4x)/(2x) du
= 1/2 ∫(u-1)/u^2 du
= 1/2 ∫(u/u^2 - 1/u^2) du
= 1/2 ln|u| + 1/2 (1/u) + C
= 1/2 ln|x^2+1| + 1/2 (1/(x^2+1)) + C

Therefore, the final answer is ∫(x^3+4x)/x^4+8x^2+1 dx = 1/2 ln|x^2+1| + 1/2 (1/(x^2+1)) + C.
Hi! To evaluate the integral, we can rewrite the given expression as follows:

∫((x^3 + 4x) / (x^4 + 8x^2 + 1)) dx

Now, let's use substitution to solve this integral. Let's set:

u = x^2 + 4

Then, the derivative du/dx = 2x. So, dx = du / (2x).

Now, we can rewrite the integral in terms of u:

∫((x^3 + 4x) / (u^2 + 1)) (du / (2x))

Notice that x^3/x and 4x/x simplify, and we are left with:

(1/2) ∫(u / (u^2 + 1)) du

Now we can integrate this expression:

(1/2) * [ln(u^2 + 1) + C]

Now, substitute back x^2 + 4 for u:

(1/2) * [ln(x^2 + 4 + 1) + C] = (1/2) * [ln(x^2 + 5) + C]

So, the evaluated integral is:

i) The light intensity at a depth of 300 feet is approximately 0.131 lumens.

ii)The light intensity of 5 lumens is reached at a depth of approximately 106.6 feet.

iii)The light intensity at the surface of the water is 12 lumens.

The equation given is:

[tex]d= -425log(\frac{I}{12} )[/tex]

where d is the depth in feet, and l is the light intensity in lumens.

i)To find the intensity of light at a depth of 300 feet:

[tex]d= -425log(\frac{I}{12} )[/tex]

[tex]or, \frac{d}{-425}=log(\frac{I}{12})[/tex]

[tex]or, 10^{\frac{d}{-425}}=\frac{I}{12}[/tex]

[tex]or, 12 X 10^{\frac{d}{-425}}=I[/tex]

Given, d= 300 feet. Hence,

[tex]or, 12 X 10^{\frac{300}{-425}}=I[/tex]

or, I = 0.131 lumens (approx.)

ii) We have been given the equation :

[tex]d= -425log(\frac{I}{12} )[/tex]

when I =5 lumens

[tex]d= -425log(\frac{5}{12} )[/tex]

or, d = 106.6 feet (approx.)

iii) For finding the light intensity at the surface of the water d=0

[tex]d= -425log(\frac{I}{12} )[/tex]

Putting d = 0 we get

[tex]0= -425log(\frac{I}{12} )[/tex]

[tex]or, log(\frac{I}{12})=0[/tex]

[tex]or, \frac{I}{12} = 10^0 = 1[/tex]

The rounding method used, the estimated speed of the space shuttle after it has slowed down is 10,200 miles per hour.

To estimate the speed of the space shuttle after it has slowed down, we round each number to the nearest hundred. The speed before the decrease is rounded to 17,600 miles per hour, and the decrease in speed is rounded to 7,400 miles per hour.

Next, we subtract the rounded decrease in speed from the rounded speed before. So, 17,600 - 7,400 = 10,200 miles per hour. This result represents the estimated speed of the space shuttle after it has slowed down.

Rounding to the nearest hundred is a way to approximate the values and make calculations simpler. However, it is important to note that rounding introduces some degree of error, and the actual speed after the decrease may differ slightly from the estimated value.

We apply the cosine of 30 degrees, becuase m(∡A) = 90° and find the hypotenuse of triangle ABC:

cos = (adjacent side) / (hypotenuse)

⇔ cos B = AB/BC ⇔

When it comes to surveys, there are several factors that can influence a person's decision to participate, such as the timing and location of the survey, the perceived relevance of the questions and incentives offered for participation. In some cases, people may opt-out of participating in a survey due to privacy concerns, lack of interest or distrust of the organization conducting the survey.

In terms of biases, survey designers should be careful of different types of biases that can affect the results, such as sampling bias, selection bias and response bias.

For example, if a survey is only given to certain demographics, the results may not be representative of the target audience.

Similarly, if the survey questions are worded in a leading or biased way, it can influence a person's response and skew the results.

It is important for survey designers to be aware of these biases and take steps to minimize their impact. This can include using random sampling techniques to ensure a representative sample, testing survey questions with focus groups to ensure they are clear and unbiased, and providing clear and transparent information about the purpose and use of the survey data.

Partial sums are:

a) limx→∞ S = L
b) The limit does not exist.
c) limx→∞ S = L
d) The limit does not exist.

We need to use the formulas for partial sums and limits of sequences.

First, recall that the nth partial sum of a series is given by:

Sn = a1 + a2 + ... + an

And the limit of a sequence (if it exists) is given by:

limn→∞ an

Now, let's use these formulas to answer the parts of the question:

a) Find lim S as n approaches infinity:

We have:

S = ax = a1 + a2 + a3 + ... + ax

Taking the limit as x approaches infinity, we get:

limx→∞ S = limx→∞ (a1 + a2 + a3 + ... + ax) = limn→∞ Sn

But we know that the series is convergent, so the limit of the partial sums exists and is equal to the sum of the series:

limn→∞ Sn = L

Therefore:

limx→∞ S = L

b) Find lim as x approaches 0:

We have:

S = ax = a1 + a2 + a3 + ... + ax

Taking the limit as x approaches 0, we get:

limx→0 S = limx→0 (a1 + a2 + a3 + ... + ax)

But as x approaches 0, the number of terms in the sum approaches infinity, so this limit does not exist.

c) Find lim S as x approaches infinity:

We have:

S = ax = a1 + a2 + a3 + ... + ax

Taking the limit as x approaches infinity, we get:

limx→∞ S = limx→∞ (a1 + a2 + a3 + ... + ax) = limn→∞ Sn

Again, we know that the limit of the partial sums exists and is equal to the sum of the series:

limn→∞ Sn = L

Therefore:

limx→∞ S = L

d) Find lim as x approaches 100:

We have:

S = ax = a1 + a2 + a3 + ... + ax

Taking the limit as x approaches 100, we get:

limx→100 S = limx→100 (a1 + a2 + a3 + ... + ax)

But as x approaches 100, the number of terms in the sum approaches infinity, so this limit does not exist.

The probability of the next coat being sold as a medium navy coat is 11 / 95 when a store sells a coat in three sizes: small, medium, and large. The coat comes in red, navy, and tan.

We need to find the probability that the next coat sold as a medium navy coat. To find the probability we need to find the total number of coats and the number of medium navy coats,

Given data:

Medium navy coat = 22

Total Number of small coats = 18 + 24 +19 = 61

Total Number of medium coats = 21 + 22 + 25 = 68

Total Number of large coats = 19 + 20 + 22 = 61

From the given data the total number of coats is = 61 + 68 + 61 = 190

The probability that the next coat sold as a medium navy coat = a number of medium navy coats / total number of coats.
