The water level at a pier is modeled by the function y= 2.5 cos(2pi/12.5) +12, where y represents the water level measured in meters, and x represents the number of hours since the last high tide. After how many hours is the water first expected to reach a depth of 12 meters? Round to the nearest tenth of an hour.
ANSWER CHOICES
1.6 hours
3.1 hours
14.4 hours
19.6 hours
Answer: 3.1 hours
Step-by-step explanation: Just took the quiz on edg.
Water will reach a depth of 12 meters after 3.1 hours approximately.
Function representing the level of water by 'y' and number of hours by 'x' is,
[tex]y=2.5\text{cos}(\frac{2\pi x}{12.5})+12[/tex]For y = 12 meters, (Substitute the value of y)
[tex]12=2.5\text{cos}(\frac{2\pi x}{12.5})+12[/tex]
[tex]12-12=2.5\text{cos}(\frac{2\pi x}{12.5})[/tex]
[tex]\text{cos}(\frac{2\pi x}{12.5})=0[/tex]
[tex]\frac{2\pi x}{12.5}=\frac{\pi }{2}[/tex] (Since, [tex]\text{cos}(\frac{\pi }{2})=0[/tex])
[tex]\frac{\pi x}{12.5}=\frac{\pi }{4}[/tex]
[tex]x=\frac{\pi }{4}\times \frac{12.5}{\pi}[/tex]
[tex]x=3.125[/tex]
[tex]x\approx3.1[/tex] hours
Therefore, water will reach a depth of 12 meters after 3.1 hours approximately.

find the x and y intercept of the graph of -9x+3y=12
Step-by-step explanation:
by graph method
x = -b/2a
b = 3, a = -9
x = -3/-18
x = 1/6
back to the equation to substitute
-9x + 3y = 12
-9(1/6) + 3y = 12
- 3/2 + 3y = 12
-3 + 6y = 24
6y = 27
y = 9/2
x = 1/6, y = 9/2

Assume that when adults with smartphones are randomly selected,41 % use them in meetings or classes. If 5 adult smartphone users are randomly selected, find the probability that exactly 2 of them use their smartphones in meetings or classes.
Answer:
0.345
Step-by-step explanation:
Use binomial probability:
P = nCr pʳ qⁿ⁻ʳ
where n is the number of trials,
r is the number of successes,
p is the probability of success,
and q is the probability of failure (1−p).
n = 5, r = 2, p = 0.41, and q = 0.59.
P = ₅C₂ (0.41)² (0.59)⁵⁻²
P = 0.345

Josiah hands out half of his tickets and Shawnda hands out one fourth of her tickets.
How many tickets do they have left altogether?
Answer:
they all have 52 left altogether
Step-by-step explanation:
they all have 2 rolls with 12 so that means they all have 24 if josiah hands out half of his tickets he would have 12 tickets left

Given that f(x) = x2 + 12x + 35 and g(x) = x + 7, find (f:g)(x) and express
the result in standard form.
Answer:
x^3+19x^2+119x+245
Step-by-step explanation:
The required value of function (f:g)(x) would be (x + 5) which is the ratio of function f(x) and g(x).
What is a quadratic equation?The quadratic equation is defined as a function containing the highest power of a variable is two.
Given that f(x) = x² + 12x + 35 and g(x) = x + 7
As per the question,
⇒ (f:g)(x) = (x² + 12x + 35) : (x + 7)
⇒ (f:g)(x) = (x² + 12x + 35) / (x + 7)
Solve the above quadratic equation, and we get
⇒ (f:g)(x) = (x² + 5x + 7x + 35) / (x + 7)
⇒ (f:g)(x) = x(x + 5) + 7(x + 5) / (x + 7)
⇒ (f:g)(x) = (x + 5)(x + 7) / (x + 7)
⇒ (f:g)(x) = (x + 5)
Therefore, the required value of function (f:g)(x) would be (x + 5).

Jack has 24 game cards. He divides them between his brother, his sister, and himself in the ratio 2:1:5.
How many cards does each get?
Answer:
brother gets 6 cards
sister gets 3 cards
he gets 15 cards
Step-by-step explanation:
this can be rewritten as
2x + x + 5x = 24
combine like terms
8x = 24
divide both sides by 8
x = 24/8
x = 3
now, multiply x by each part of the ratio.
his brother = 2 * 3 = 6
his sister = 1 * 3 = 3
himself = 5 * 3 = 15

Which is a statistical question?
Question 1 options:
How many even numbers are there between 10 and 20?
How many letters are in the word "octopus"?
How many minutes does it take to travel to school?
Answer:
How many minutes does it take to travel to school?
Step-by-step explanation:
A statistical question means you expect variability in the responses.
For instance, if you look at the first question, there's only 1 answer, so there's no variability. If you look at the second question, there's also only 1 answer.
How many minutes does it take to travel to school?
======================================================
Explanation:
Choice A is not a statistical question because we don't need to use statistics to find the answer. We simply count out the number of even numbers between 10 and 20. There's no need to draw a random sample of elements and do statistical analysis.
The same goes for choice B as well. There are 7 letters in this word and this value does not fluctuate/change.
Therefore we rule out choices A and B.
Choice C on the other hand has its answer vary depending on which person you ask. If you ask enough people, then you can find the average number of minutes, which is one tool to do statistics. This variable is considered a random variable (RV).

Which choice is the equation of the line that passes through the point (5, 19) and has a slope of m =12 and is written in slope-intercept form?
Answer: y = 12x - 41
Step-by-step explanation:
The choices are not given, but you can figure this out.
Slope intercept form is y = mx + b
Substitute the y and x-values into the equation to calculate b, the y-intercept.
19 = 12(5) + b
19 = 60 + b
-60 + 19 =b
-41 = b
Write the equation with y and x, include the given slope and the calculated y-intercept:
y = 12x + 41
