A theme park guest takes an innertube into the wave pool. The innertube moves up and down in a way such that the height h of the innertube, in meters, above the floor of the pool can be modeled by the function h = asinbx + 5. When the wave pool is turned on, the innertube's height fluctuates between 2 meters and 8 meters, with an interval of 12 seconds between maximums. Based on the context of the problem, what are the values of a and b?
Answers
So we are told that the height of the innertube in meters is given by:
[tex]h(x)=a\sin (bx)+5[/tex]The minimum height is 2 meters, the maximum is 8 meters and the time between two consecutive maximums is 12 seconds. Here is important to note a few properties of the sine. First of all, the minimum value of sin(bx) is -1 and its maximum value is 1. Then the height of the innertube is minimum when sin(bx)=-1 and maximum when sin(bx)=1. With these two values we can build two equations for a:
[tex]\begin{gathered} \min (h)=2=a\cdot(-1)+5 \\ \max (h)=8=a\cdot1+5 \end{gathered}[/tex]So we have:
[tex]\begin{gathered} 2=-a+5 \\ 8=a+5 \end{gathered}[/tex]Substracting 5 from both sides of the second equation we get:
[tex]\begin{gathered} 8-5=a+5-5 \\ 3=a \end{gathered}[/tex]Using this in the first equation gives us:
[tex]\begin{gathered} 2=-3+5 \\ 2=2 \end{gathered}[/tex]Which confirms that a=3. Now we have to find b. For this purpose we can recal another property of the sine. Its period i.e. the distance (in this case the time) between two consecutive maximums is given by:
[tex]\frac{2\pi}{b}[/tex]Since we know this time is 12 seconds we get:
[tex]\frac{2\pi}{b}=12[/tex]If we multiply both sides by b and divide them by 12 we get:
[tex]\begin{gathered} \frac{2\pi}{b}\cdot\frac{b}{12}=12\cdot\frac{b}{12} \\ \frac{2}{12}\pi=b \\ \frac{\pi}{6}=b \end{gathered}[/tex]So we have:
[tex]a=3\text{ and }b=\frac{\pi}{6}[/tex]Which means that the answer is the second option.

if 5% more than A is B, and B is 15% less than C, what is the ratio of A to C?
Answers
For the given condition when B is 5% more than A and B is 15% less than C then ratio of A to C is equal to 17 : 21.
As given in the question,
Let value of A is equal to 100
As per given condition we have,
B is 5% more than A
5% of 100
= (5/100) × 100
= 5
So B is equal to
= 100 +5
= 105
A:B = 100/105
= 20/21
B is 15% less than C
let C= 100
15 % of 100
= (15/100) × 100
= 15
Value of B is equal to
= 100 - 15
= 85
B:C = 85 : 100
= 17 : 20
Ratio A : B : C
= 340 : 357 : 420
Ratio A : C = 340 : 420
= 17 :21
Therefore, for the given condition when B is 5% more than A and B is 15% less than C then ratio of A to C is equal to 17 : 21.

Long Multiplication
1. Arrange the numbers one on top of the other and line up the place values in columns. The number with the most digits is usually placed on top as the multiplicand.
This will be written as follows:
467
x 48
---------------
2. Starting with the ones digit of the bottom number, the multiplier, multiply it by the last digit in the top number.
This product is 8*7 = 56
3. If that answer is greater than nine, write the ones place as the answer and carry the tens digit.
We should write 6 and carry 5:
467
x 48
---------------
6 (carry 5)
4. Proceed right to left. Multiply the ones digit of the bottom number to the next digit to the left in the top number. If you carried a digit, add it to the result and write the answer below the equals line. If you need to carry again, do so.
The next product is 8*6 = 48. Adding the carry: 48+5=53, Write 3, carry 5:
467

the amount of water a washing machine uses varies directly with the number of loads of laundry washed. if a machine uses 65 gallons of water to wash 5 loads, how much water will be used to was 8 loads?
Answers
Let g represent gallons of water and let L represent loads.
Here, the gallons of water varies directly with the number of loads, thus we have:
g ∝ L
Now introduce a constant k:
g = kL
65 gallons is used to wash 5 loads, thus we have:
65 = k * 5
Let's solve for k:
65 = 5k
Divide both sides by 5:
[tex]\begin{gathered} \frac{65}{5}=\frac{5k}{5} \\ \\ 13=k \end{gathered}[/tex]To find the amount of water that will be used to wash 8 loads, we have:
g = kl
We are to find g, substitute 13 for k and 8 for l:
g = 13 x 8
g = 104
Therefore, to wash 8 loads, 104 gallons of water is needed.

Answer:

[tex]\begin{gathered} 0.000041\leq\sigma^2\leq0.00015 \\ 0.0064\leq\sigma\leq0.0125 \end{gathered}[/tex]b. The standard deviation is at an acceptable level
Explanation:
The confidence interval for the variance can be calculated as:
[tex]\frac{(n-1)s^2}{\chi^2_{\frac{\propto}{2}}}\leq\sigma^2\leq\frac{(n-1)s^2}{\chi^2_{1-\frac{\propto}{2}}}[/tex]Where n is the size of the sample, s² is the variance of the sample, (1-∝) is the level of confidence, and χ² is the value of chi-square with n-1 degrees of freedom.
In this case, we get that n is 14 tablets, s² is 0.000071, and 1-∝ = 90%, so ∝ is 10%.
Then, the values of chi-square with 13 (14 -1) degrees of freedom is:
[tex]\begin{gathered} \chi^2_{\frac{\propto}{2}}=22.36 \\ \chi^2_{1-\frac{\propto}{2}}=5.89 \end{gathered}[/tex]Therefore, the interval of confidence for the population variance is:
[tex]\begin{gathered} \frac{(14-1)(0.000071)}{22.36}\leq\sigma^2\leq\frac{(14-1)(0.000071)}{5.89} \\ 0.000041\leq\sigma^2\leq0.00015 \end{gathered}[/tex]Then, the standard deviation is the square root of the variance, so the interval of confidence for the population standard deviation is:
[tex]\begin{gathered} \sqrt[]{0.000041}\leq\sigma\leq\sqrt[]{0.00015} \\ 0.0064\leq\sigma\leq0.0125 \end{gathered}[/tex]Finally, since the upper limit of the interval for the standard deviation is less than 0.15 milligrams, we can say that the population standard deviation is at an acceptable level with a confidence level of 90%

Describe a series of transformations Matt can perform to device if the two windows are congruent
Answers
Congruent shapes are produced when the three transformations—rotations, reflections, and translations—are combined. Any pair of congruent shapes can actually be matched to one another by combining one or more of these three transformations.
Definition of transformationsAn object's shape and/or location can vary in each of the four possible transformations of a point, line, or geometric figure. Pre-Image refers to the shape of the object before transformation, whereas Image refers to the location and shape of the object after transformation.
Data Presented
We now understand that stiff transformations preserve the size and shape of the figures (reflections, translations, and rotations). The pre-image and the actual image always concur.
The following transformational skills belong to Matt:
Reflection
A reflection maintains its initial form because the Comparable locations from the pre-image to the picture remain at the same distance from the line of reflection.
Rotations as a Congruence Transformation
A rotating figure twists. Despite being the same size and shape as before, the figure appears to have toppled over. A clock is an excellent example of how the globe actually rotates. Every hour or every day, a clock's connecting arms revolve around its axis. The degree of a rotation determines what kind of rotation it is; popular rotations include those of 90, 180, and 270 degrees. Before going back to its original position, the figure rotates a full 360 degrees. the clockwise or counterclockwise direction in which a revolution happens. This data can be used to determine the degree, amount, and a revolution's speed and direction.
Congruence translational transformation
When an object or shape is transferred from one location to another without altering its size, shape, or orientation, we refer to the transfer as a movement. A translation, often known as a slide, involves moving every point on an object or shape uniformly and in one direction.

Answers
The account balance at the end of the month is $1051.
How is the balance estimated in a bank account?To estimate the balance in a bank account, one has to add the credit to the available balance of the account and subtract the debited amount from the same.
It is given that the account balance initially is $843.
The deposited balances are $92, $404, $39 and $51.
Add the credited amount to the account balance.
So, the current amount is = $843+ $92+ $404+ $39+ $51= $1429
The withdrawal amount is $70, $87 and $221
Subtract the debited amount to the account balance.
So, the current amount is = $1429 - $70 -$87 - $221 = $1051.
So, the account balance at the end of the month is $1051.

Hey there!
Whenever, you hear or see the word “constant” think of the definition ‘a specific number or value that never changes in a particular equation’
16.2 - 3(4) + 14/2
= 16.2 - 12 + 14/2

= 4.2 + 7
= 11.2
Now, that we have that information out the way, we can answer your equation
Your CONSTANTS aren’t:
• -3(4) because we had to simplify it and convert it to: -12
• 14/2 because we had to simplify that as well and it converted it to: 7
(That’s how we figured out to make the equation much easier to breakdown)
(By the way, you can use PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition, & Subtraction) to solve for the overall problem, like how I did for you :))

Answer:
3 ≤ x < ∞
Step-by-step explanation:
You want the domain of a square root function shifted right 3 units and up 1 unit. It goes through points (3, 1), (4, 2) and (7, 3).
DomainThe domain of a function is the set of values of the independent variable for which the function is defined. It is the horizontal extent of the graph.
The graph of the given square root function extends to the right from x=3.
The domain is 3 ≤ x < ∞. In interval notation, it is [3, ∞).
