A group of 4 frieds decide to attend a night of dinner and dancing on a cruise ship. The dinner and dance cruise will last 4 hours. The ship travels 18 km upstream and then travels back to the starting point. The river has a current of 2 km an hour. What is the cruise ship's speed and how long was the upstream journey
Answer:
The speed of the cruise ship relative to the current is approximately 9.424 kilometers per hour.
The cruise ship's will need 2.425 hours for its upstream journey.
Step-by-step explanation:
The total time of the cruise ([tex]t[/tex]), in hours, is the sum of the times for the upstream ([tex]t_{u}[/tex]) and downstream journeys ([tex]t_{d}[/tex]), in hours. Let suppose that both river and cruise ship travel at constant velocity, the cruise ship travels against the current in its upstream journey, whereas it is in favor of the current in the downstream journey, meaning that:
[tex]t = t_{u} + t_{d}[/tex]
[tex]t = \frac{x}{v_{S/C} - v_{C}} + \frac{x}{v_{S/C} + v_{C}}[/tex] (1)
Where:
[tex]v_{C}[/tex] - Speed of the current, in kilometers per hour.
[tex]v_{S/C}[/tex] - Speed of the cruise ship relative to the current, in kilometers per hour.
If we know that [tex]t = 4\,h[/tex], [tex]x = 18\,km[/tex] and [tex]v_{C} = 2\,\frac{km}{h}[/tex], then we have the following expression:
[tex]4\,h = (18\,km)\cdot \left(\frac{1}{v_{S/C} - 2\,\frac{km}{h} } + \frac{1}{v_{S/C}+2\,\frac{km}{h} }\right)[/tex]
[tex]\frac{2}{9} = \frac{1}{v_{S/C}-2} + \frac{1}{v_{S/C}+2}[/tex]
[tex]\frac{2}{9} = \frac{2\cdot v_{S/C}}{v_{S/C}^{2}-4}[/tex]
[tex]2\cdot v_{S/C}^{2} - 8 = 18\cdot v_{S/C}[/tex]
[tex]2\cdot v_{S/C}^{2}-18\cdot v_{S/C}-8 = 0[/tex]
The roots of the second order polynomial are, respectively:
[tex]v_{S/C,1} \approx 9.424\,\frac{km}{h}[/tex], [tex]v_{S/C,2} \approx -0.424\,\frac{km}{h}[/tex]. Since the speed is the magnitude of the velocity, a realistic solution must be a positive quantity and the solution is:
[tex]v_{S/C} \approx 9.424\,\frac{km}{h}[/tex]
The speed of the cruise ship relative to the current is approximately 9.424 kilometers per hour.
And the time needed for the upstream journey is:
[tex]t_{u} = \frac{x}{v_{S/C}- v_{C}}[/tex] (2)
If we know that [tex]x = 18\,km[/tex], [tex]v_{S/C} \approx 9.424\,\frac{km}{h}[/tex] and [tex]v_{C} = 2\,\frac{km}{h}[/tex], then time for the upstream journey is:
[tex]t_{u} = \frac{18\,km}{9.424\,\frac{km}{h}-2\,\frac{km}{h} }[/tex]
[tex]t_{u} = 2.425\,h[/tex]
The cruise ship's will need 2.425 hours for its upstream journey.
A consumer group claims that the average annual consumption of high fructose corn syrup by a person in the U.S. is 48.8 pounds. You believe it is higher. You take a simple random sample of 35 people in the U.S. and find an average of 53.8 pounds with a standard deviation of 4.4 pounds. Test at 1% significance. Round to the fourth
Answer:
[tex]6.7159[/tex]
Step-by-step explanation:
[tex]\mu=48.8\\n=35\\\bar{x}=53.8\\\sigma=4.4\\\alpha=1\%=0.01[/tex]
Null and alternative hypothesis :
[tex]H_0:\mu=48.8\\H_a:\mu>48.8[/tex]
Test statistic,
[tex]t=\frac{\bar{x}-\mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
[tex]\Rightarrow t=\frac{53.8-48.8}{\frac{4.4}{\sqrt{35}}}[/tex]
[tex]\Rightarrow t=\frac{5\times 5.91}{4.4}[/tex]
[tex]\Rightarrow t=6.715[/tex]
Test statistic [tex]t=6.715[/tex]
[tex]P-[/tex]value [tex]=P(t>6.715)[/tex]
[tex]P-[/tex] value [tex]=0.0001[/tex] by the p- table
Significance level [tex]0.01[/tex]
[tex]p-[/tex]value [tex]<0.01[/tex]

Find the equation of the parabola with focus (5,0) and directrix x =5
Answer:
y²=20x
Step-by-step explanation:
Note: I'm assuming you mean x=-5 for the directrix because what you're asking isn't possible
Since we are given a horizontal directrix, the parabola must also be horizontal.
Horizontal Parabola:
(y-k)² = 4p(x-h)
Vertex: (h, k)
Focus: (h+p, k)
Directrix: x = h - p
Since the focus of the parabola is (5,0), then k=0 and h+p=5. We also know that since the directrix is x=-5, then -5=h-p. If we set these equations equal to each other, we can solve for h and p:
h+p=5
h-p=-5
2p=10
p=5
Since p=5, then h=0. Therefore, we have for our equation of the parabola:
(y-k)² = 4p(x-0)
(y-0)² = 4(5)(x-0)
y²=20x

What is Pythagoras' theorem?In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem.
Given:
A boy is flying a kite.
The length of the string is 20 meters and the horizontal distance between the boy and the kite is 15 meters.
Assuming there is no slack in the string,
then the height of the kite is,

Julie has 21 colored pencils and 27 crayons. What is the ratio of crayons to colored pencils?
9:7 is the ratio of crayons to colored pencils.
What is the ratio?The ratio can be defined as the number that can be used to represent one quantity as a percentage of another. Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two objects.
The ratio of crayons to colored pencils can be found by dividing the number of crayons by the number of colored pencils:
The ratio of crayons to colored pencils = 27/21
Simplifying this ratio by dividing both the numerator and denominator by 3, we get:
The ratio of crayons to colored pencils = 9/7
Therefore, the ratio of crayons to colored pencils is 9:7.

An indoor running track is 200 meters in length. During a 3,000-meter race, runners must complete 15 laps of the track. An electronic timing device records the time it takes each runner to complete a lap for every lap in the race. These are called lap times. The histogram below displays the lap times for Stefano, a runner in the 3,000-meter race.
A histogram titled Stefano apostrophe s 3,000 meter race lap times has lap times (seconds) on the x-axis and frequency on the y-axis. 32 to 33, 1; 34 to 35, 1; 36 to 37, 1; 37 to 38, 4; 38 to 39, 5; 39 to 40, 1; 40 to 41, 2.

There were six laps with times less than 37 seconds is false.
There were three laps with times greater than 38 seconds, is also false.

What are the vertical and horizontal asymptotes of f (x) = StartFraction 2 x Over x minus 1 EndFraction?
horizontal asymptote at y = 0, vertical asymptote at x = 1
horizontal asymptote at y = 2, vertical asymptote at x = 1
horizontal asymptote at y = 1, vertical asymptote at x = 0
horizontal asymptote at y = 1, vertical asymptote at x = 2
Answer:
horizontal asymptote at y = 2, vertical asymptote at x = 1
Step-by-step explanation:
We are given the following function:
[tex]f(x) = \frac{2x}{x - 1}[/tex]
Horizontal asymptote:
The horizontal asymptote of a function is the limit of the function as the input, in this case x, goes to infinity. When we want to find the limit of x going to infinity of a fraction we consider the term with the largest exponent on both the numeration and the denominator. So
[tex]\lim_{x \rightarrow \infty} \frac{2x}{x - 1} = \lim_{x \rightarrow \infty} \frac{2x}{x} = \lim_{x \rightarrow \infty} 2 = 2[/tex]
So there is a horizontal asymptote at y = 2
Vertical asymptote:
Vertical asymptotes happens at points outside the function domain.
In this question, we have a fraction, in which the denominator cannot be 0. So
[tex]x - 1 = 0 \rightarrow x = 1[/tex]
Thus, there is a vertical asymptote at x = 1.
The correct option is:
horizontal asymptote at y = 2, vertical asymptote at x = 1

Explanation
To find the average we need to find the mean. So you have
87,93,96, and 89. Add it up and you get 365. Next you have to divide it by how many numbers there are, so 365 divided by 5 and you get 73.
