Answer:
The cosine function to model the height of a water particle above and below the mean water line is h = 2·cos((π/30)·t)
Step-by-step explanation:
The cosine function equation is given as follows h = d + a·cos(b(x - c))
Where:
[tex]\left | a \right |[/tex] = Amplitude
2·π/b = The period
c = The phase shift
d = The vertical shift
h = Height of the function
x = The time duration of motion of the wave, t
The given data are;
The amplitude [tex]\left | a \right |[/tex] = 2 feet
Time for the wave to pass the dock
The number of times the wave passes a point in each cycle = 2 times
Therefore;
The time for each complete cycle = 2 × 30 seconds = 60 seconds
The time for each complete cycle = Period = 2·π/b = 60
b = π/30 =
Taking the phase shift as zero, (moving wave) and the vertical shift as zero (movement about the mean water line), we have
h = 0 + 2·cos(π/30(t - 0)) = 2·cos((π/30)·t)
The cosine function is h = 2·cos((π/30)·t).

Two circles are drawn below. The diameter of the smaller circle is a radius of the larger circle. What is the ratio of the smaller circle's circumference to the larger circle's circumference? Give your answer in fully simplified form. It should look like "x:y", where x and y are replaced by integers. [asy] size(4cm); pair o=(0,0); pair x=(0.9,-0.4); draw(Circle(o,sqrt(0.97))); draw(Circle((o+x)/2,sqrt(0.97)/2)); dot(o); dot(x); dot(-x); draw(-x--x); [/asy] Hint(s): Read the question carefully. Does it ask about a ratio of areas? Of radii? Of diameters? Of circumferences? Which question did you answer? Which was asked?
Answer:
1 : 2
Step-by-step explanation:
The ratio is ...
small dia : large dia = 1 : 2 = small circumference : large circumference
__
Further explanation
The diameter of the small circle is the radius of the large circle. Since the large circle's diameter is twice the length of its radius, the ratio of circle diameters is ...
small : large = 1 : 2
We multiply the diameter by π to get the circumference. Multiplying both these numbers by π will give the ratio of the circumferences. In order to reduce the ratio to lowest terms we must divide by π again:
dia ratio = circumference ratio = lowest terms ratio
1 : 2 = π : 2π = 1 : 2

Assume that adults have it scores that are normally distributed with a mean of 100 standard deviation of 15 find probability that randomly selected adult has an Iq between 89 and 111
Answer:
0.5346
Step-by-step explanation:
Find the z-scores.
z = (x − μ) / σ
z₁ = (89 − 100) / 15
z₁ = -0.73
z₂ = (111 − 100) / 15
z₂ = 0.73
Find the probability.
P(-0.73 < Z < 0.73)
= P(Z < 0.73) − P(Z < -0.73)
= 0.7673 − 0.2327
= 0.5346
The area of a rectangle is given by the expression 2x^3+5x^2-2x+3 . If the length of the rectangle is given by the expression x + 3, find the expression that represents the width
Answer:
2x^2 - x + 1
Step-by-step explanation:
This is polynomial long division:
Divide x + 3 into 2x^3 + 5X^2 - 2x + 3:
Divide 2x^3 by x = 2x^2
Multiple 2x^2 by (x + 3) = 2x^3 + 6x^2
Subtract that from 2x^3 + 5X^2 - 2x + 3 = -x^2 -2x + 3
Divide -x^2 by x = -x
Multiple -x by (x + 3) = -x^2 - 3x
Subtract that from -x^2 - 2x + 3 = x + 3
Divide x by x = 1
Multiple 1 by (x + 3) = x + 3
Subtract from x + 3 = 0

There are 6 different colored pens in a box. Each pen has a unique color. In how many orders can 4 pens be chosen? In other words, what is the number of permutations of picking 4 pens from the box?
Answer:
360 different permutations.
Step-by-step explanation:
It goes 6*5*4*3 because as you pick the pens the amount of pens in the jar would obviously decrease. Picking one leaves you with 5 new options. If you repeat that 4 times then you are left with 360 options.
The number of permutations of picking 4 pens from the box is 6P4, or 6!/(6-4)! = 654×3 = 360.
We have 6 pens and we are picking 4 of them. The order in which we pick the pens matters, so we are dealing with permutations.
The number of permutations of n objects is given by n!, or n factorial. So, the number of permutations of 6 objects is 6!.
However, we need to divide by the number of permutations of the 2 pens that we are not picking. There are 2 pens that we are not picking, so the number of permutations of those pens is 2!.
Therefore, the number of permutations of picking 4 pens from the box is 6!/(6-4)! = 654×3 = 360.

What is parabola?A parabola is a plane curve that is mirror-symmetrical and roughly U-shaped in mathematics. It fits several seemingly disparate mathematical descriptions, all of which can be shown to define the same curves.
The graph of the function f(x) = (x + 2)(x + 6) is a downward facing parabola that intersects the x-axis at x = -6 and x = -2.
Therefore, we can conclude that the function is negative for all real values of x where x < -6 or x > -2 (outside the x-intercepts).
The function is positive for all real values of x where x lies between the x-intercepts, which means -6 < x < -2.
Therefore, the statement that is true is: "The function is negative for all real values of x where x < -6 or x > -2. The function is positive for all real values of x where -6 < x < -2."

Pentagon A’B′C′D′E’, is the image of pentagon ABCDE under a dilation with a scale factor of 5/2
Answer:
The length of segment A'E' is 5 units
Explanation:
From the included graph the coordinates of the points A and E, in the pentagon ABCDE with reference to point A are;
A- (0, 0)
E- (0, 2)
The length of the segment AE = √((2-0)² + (0 - 0)²) = √2² = 2
When a pentagon ABCDE is dilated to pentagon A'B'C'D'E' with a scale factor of 5/2, we have;
Length of segment A'E' = 5/2 × Length of segment AE
Therefore;
Length of segment A'E' = 5/2 ×2 = 5 units.
The length of segment A'E' is 5 units.
This question is based on distance formula.The length of segment A'E' is 5 units.
Given:
Pentagon A’B′C′D′E’, is the image of pentagon ABCDE under a dilation with a scale factor of 5/2.
From the given graph, the coordinates of the points A and E, in the pentagon ABCDE with reference to point A are;

Answer:
B. 1296 in.^2
Step-by-step explanation:
The rectangles are similar, and sides ST and YZ are corresponding sides.
The linear scale factor is k = YZ/ST = 24/8 = 3
The area scale factor is k^2 = 3^2 = 9
A = 144 sq in. * k^2 = 144 sq in. * 9 = 1296 sq in.
Answer: B. 1296 in.^2
Answer:
4)1,296in^2
5)510.4ft
Step-by-step explanation:
4)
24/8=3 This is the dilation
144/8=18 This is the side length for QRST
18*3=54 The side length for WXYZ
24*54=1296 The area of WXYZ
5)
319*8/5 Your fence with a scale factor of 8/5
319*1.6 Changing 8/5 into fraction form
319*1.6=510.4 The length of the friend's fence.
Hope this helps. I could not see the end of the last question so I am sorry if it is not written properly.

. A car bought for $20,000. Its value depreciates by 10% each year for 3 years. What is the car's worth after3 years?
Answer:
$14,580
Step-by-step explanation:
To start off, 10% of 20,000-one easy way to do this is to multiply 20,000 by 0.1, which is 10% in decimal form
-In doing that, you get 2,000
-Now the question says that the value is depreciated which means it goes down in value, so subtract 2,000 from 20,000 to 18,000
-the value of the car after one year is now $18,000
Now, let's move to the second year. This time find 10% of 18,000
-multiply 18,000 by 0.1 to get 1,800
-since the value is depreciating, or becoming less, we will subtract 1,800 from 18,000 to get 16,200
-the value of the car after two years is now $16,200
Finally, let's look at the value of the car after three years. Only this time, we will now find 10% of 16,200
-multiply 16,200 by 0.1 to get 1,620
-since value is being depreciated, or lessened, we will once again be subtracting. Subtract 1,620 from 16,200 to get 14,580
Therefore, the value of the car after three years is now $14,580.
