11. An amusement park charges $45 per person for admission. A season pass
costs $112 per person.
a. Write the first five terms of an arithmetic sequence that represents the
total cost of admission for the number of visits in a season.
b. How many times does a person have to visit the park for a season pass
to be the better deal? Explain.
To represent the total cost of admission for the number of visits in a season, an arithmetic sequence can be created with a common difference of $45. The cost of admission for the first visit is $45, and the sequence can be extended to five terms. To determine when a season pass becomes the better deal, compare the total cost of admission with the cost of a season pass. A person would have to visit the park at least 3 times for a season pass to be the better deal.
Explanation:a. To represent the total cost of admission for the number of visits in a season, we can create an arithmetic sequence. The common difference will be the cost of admission each time a person visits the park, which is $45. The first term can be the cost of admission for the first visit, which is also $45. So, the arithmetic sequence will be:
Total: $45Total: $90Total: $135Total: $180Total: $225b. To find out how many times a person has to visit the park for a season pass to be the better deal, we need to compare the total cost of admission for the number of visits with the cost of a season pass. In this case, the season pass costs $112 per person, so we need to find the number of visits that would equal or exceed the cost of a season pass. From the arithmetic sequence we created in part a, we can see that a person would have to visit the park at least 3 times for the total cost of admission to equal or exceed the cost of a season pass. Therefore, a person would have to visit the park at least 3 times for a season pass to be the better deal.

Answer:
it's a
Step-by-step explanation:
Without more information on triangle QRS, the potential true equations could be 'sin(100 degrees) / 3.5 = sin(S) / 2.4' and 'sin(100 degrees) / 2.4 = sin(Q) / 3.5' based on the law of sines.
Explanation:The question is asking which equation formed by the law of sines is true for the triangle QRS. As it is not completely clear from the given data, let's apply the law of sines in a general form for triangle QRS: sin(Q)/QR = sin(R)/RS = sin(S)/SQ. Comparing this to the provided options we could suggest that the correct equation could be: sin(100 degrees) / 3.5 = sin(S) / 2.4 and sin(100 degrees) / 2.4 = sin(Q) / 3.5. These are possibilities if we assume that the angle at Q is 100 degrees and the lengths of the sides opposite these angles are 3.5 and 2.4 respectively. However, without more specific information about triangle QRS, these conclusions are speculative.

A cylinder has has a volume of 1884 cm cubed. Find the volume of a cone with the same radius and height as the cylinder.
Answer:
The volume of the cone with the same radius and height as the given cylinder is approximately [tex]\(459.325 \, \text{cm}^3\)[/tex].
Explanation:
To find the volume of a cone with the same radius and height as the given cylinder, we'll use the formula for the volume of a cone:
[tex]\[ V = \frac{1}{3} \pi r^2 h \][/tex]
Given that the cylinder has a volume of 1884 cm³, and the radius [tex](\(r\))[/tex] and height [tex](\(h\))[/tex] of the cone are the same as the cylinder, we can first find the radius and height of the cylinder.
The volume of the cylinder is given by:
[tex]\[ V_{\text{cylinder}} = \pi r^2 h \][/tex]
Given [tex]\(V_{\text{cylinder}} = 1884 \, \text{cm}^3\)[/tex], we can solve for [tex]\(r^2 h\)[/tex], the product of the square of the radius and the height:
[tex]\[ r^2 h = \frac{1884}{\pi} \][/tex]
Now, we need to find the radius and height of the cylinder. Since we're told that the cone has the same radius and height as the cylinder, we can use these values for the cone as well.
[tex]\[ r^2 h = \frac{1884}{\pi} \][/tex]
Given that [tex]\( r = h \)[/tex], we can substitute [tex]\(r\)[/tex] for [tex]\(h\)[/tex] to get:
[tex]\[ r^3 = \frac{1884}{\pi} \][/tex]
[tex]\[ r = \sqrt[3]{\frac{1884}{\pi}} \][/tex]
Now that we have the value of [tex]\(r\)[/tex], we can find the volume of the cone using the formula for the volume of a cone:
[tex]\[ V_{\text{cone}} = \frac{1}{3} \pi r^2 h \][/tex]
[tex]\[ V_{\text{cone}} = \frac{1}{3} \pi \left( \sqrt[3]{\frac{1884}{\pi}} \right)^2 \left( \sqrt[3]{\frac{1884}{\pi}} \right) \][/tex]
[tex]\[ V_{\text{cone}} = \frac{1}{3} \pi \left( \frac{1884}{\pi} \right)^{2/3} \left( \frac{1884}{\pi} \right)^{1/3} \][/tex]
[tex]\[ V_{\text{cone}} = \frac{1}{3} \pi \left( \frac{1884^2 \cdot 1884}{\pi^2} \right)^{1/3} \][/tex]
[tex]\[ V_{\text{cone}} = \frac{1}{3} \pi \left( \frac{1884^3}{\pi^2} \right)^{1/3} \][/tex]
[tex]\[ V_{\text{cone}} = \frac{1}{3} \pi \left( \frac{671161856}{9.869604401} \right)^{1/3} \][/tex]
[tex]\[ V_{\text{cone}} \approx \frac{1}{3} \pi \left( 67968372.82 \right)^{1/3} \][/tex]
[tex]\[ V_{\text{cone}} \approx \frac{1}{3} \pi \cdot 438.327 \][/tex]
[tex]\[ V_{\text{cone}} \approx 459.325 \, \text{cm}^3 \][/tex]

A person invests 9000 dollars in a bank. The bank pays 4.25% interest compounded daily. To the nearest tenth of a year, how long must the person leave the money in the bank until it reaches 19600?
The person must invest the money in the bank for 18 years to reach $19600, if a person invests 9000 dollars in a bank and the bank pays 4.25% interest compounded daily.
Step-by-step explanation:
The given is,
A person invests 9000 dollars in a bank
The bank pays 4.25% interest compounded daily
Future amount $19600
Step:1
Formula to calculate the future investment with compounded daily,
[tex]A = P (1+\frac{r}{n})^{nt}[/tex]................................(1)
Where, A - Future amount
P - Initial investment
r - Interested rate
n - No.of times for a year
t - No.of years
Step:2
From the given values,
A = $ 19600
P = $ 9000
r = 4.25 %
n = 365 ( ∵ Compounded daily )
Equation (1) becomes,
[tex]19600 = 9000(1+\frac{0.0425}{365})^{365t}[/tex]
[tex]\frac{19600}{9000}= (1+0.000116438)^{365t}[/tex]
[tex]2.177778=(1.000116438)^{365t}[/tex]
( Take log on both sides )
[tex]log 2.17778= log (1.000116438)^{365t}[/tex]
[tex]log 2.17778=( 365t)log (1.000116438)[/tex]
Substitute the log values,
[tex]0.338014 = (365t)(0.000050565)[/tex]
[tex]\frac{0.338014}{0.000050565}= 365t[/tex]
[tex]6684.6842 = 365t[/tex]
[tex]t = \frac{6684.6842}{365}[/tex]
= 18.314
≅ 18 years
No.of years, t = 18 years
Result:
The person must invest the money in the bank for 18 years to reach $19600, if a person invests 9000 dollars in a bank and the bank pays 4.25% interest compounded daily.
It will take approximately 18.4years for the person to make 19600
The formula for calculating the compound amount is expressed as:
[tex]A=P(1+\frac{r}{n} )^{nt}[/tex] where:
A is the amount
P is the amount invested
n is the compounding amount
t is the time taken
Given the following parameters
A = 19600
P = 9000
r = 4.25% = 0.0425
n = 365 (compounded daily)
Substitute the given parameters into the formula to get the time "t"
[tex]19600 = 9000(1+\frac{0.0425}{365} )^{365t}\\2.1778 = (1+0.0001164)^{365t}\\2.1778 = (1.0001164)^{365t}\\log2.1778 = 365tlog(1.0001164)\\0.3380 = 0.0184t\\t = \frac{0.3380}{0.0184} \\t \approx 18yrs[/tex]
