What is sinusoidal wave?
A mathematical curve defined in terms of the sine trigonometric function, of which it is the graph, is known as a sine wave, sinusoidal wave, or simply sinusoid. It is a smooth periodic function and a particular kind of continuous wave.
Let the graphs of y = sin(x) and y =sin(2x) are given.
From this graphs we have to find the value of c and d.
First from y = sin(x) to find the value of 'a'.
consider the point [tex](a, -\frac{4}{5})[/tex]
⇒
[tex]sin(a) = -\frac{4}{5} \\a = sin^-^1(-\frac{4}{5})\\ a = -53.13[/tex]
Now to find the value of 'c'.
Plug a = -53.13 in y = sin(2x)
[tex]sin(2a) = c\\sin(2(-53.13)) = 0.52622\\sin2a= 0.53[/tex]
Hence, the value of 'c' is c = 0.53.
Now to find the value of d.
First y = sin(x) to find the value of b.
Consider, the point [tex](b, \frac{5}{13})[/tex]
⇒
[tex]sinb = \frac{5}{13} \\b = sin^-^1(\frac{5}{13})\\ b = 22.62[/tex]
Now to find value of d.
Plug b = 22.62 in y = sin(2x)
[tex]sin(2b) = d\\sin(2(22.62)) = 0.95138\\sin(2b) = 0.95[/tex]
So, the value of 'd' is 'd = 0.95'.
Hence, from the given graphs the values of c and d are, c = 0.53,
d = 0.95.

Answers
The perpendicular equation is y = -1/3x + 10 Option A
How to find perpendicular of an equation?You can find this by first realizing that perpendicular lines have opposite and reciprocal slopes. So since it starts at 3 we flip it and make it a negative and the new slope is -1/3.
Now we can use that and the point to get the y intercept using slope intercept form.
y = mx + c
m = gradient of the line
c = y -intercept
8 = (-1/3)(6) + c
8 = -2 + c
10 = c

Answers
The lower limit of the confidence interval is 51%, which is above 55%, so the Republican should expect to win.
What does confidence interval mean?
Your estimate's mean plus and minus the range of that estimate's fluctuation is called a confidence interval.
If you repeat your test, you can expect your estimate to fall between these numbers with a reasonable degree of certainty. In statistics, confidence is another word for probability.
A confidence interval of proportions has two bounds, a lower bound and an upper bound.
These bounds depend on the sample proportion and the margin of error.
The lower bound is the sample proportion subtracted by the margin of error.
The upper bound is the margin of error added to the sample proportion.
In this problem, we have that:
Sample proportion 53%
Margin of error 2%
53 - 2 = 51%
53 + 2 = 55%
Hence, the lower limit of the confidence interval is 51%, which is above 55%, so the Republican should expect to win.

An exponential function is a Mathematical function in the form f (x) = ax, where “x” is a variable and “a” is a constant which is called the base of the function and it should be greater than 0. The most commonly used exponential function base is the transcendental number e, which is approximately equal to 2.71828.
An exponential function is defined by the formula f(x) = ax, where the input variable x occurs as an exponent. The exponential curve depends on the exponential function and it depends on the value of the x.
The exponential function is an important mathematical function which is of the form
f(x) = ax
Where a>0 and a is not equal to 1.
x is any real number.
If the variable is negative, the function is undefined for -1 < x < 1.
Here,
“x” is a variable
“a” is a constant, which is the base of the function.

Answers
If more than 25 people are added, the total revenue will be r(x) = $ 50, with the x = 5 size group producing the highest revenue for the agency.
what is marginal revenue ?The law of diminishing returns dictates that marginal revenue will eventually begin to decline as output level rises, even though it can remain constant above a certain threshold of output.
calculation
If a group of 25 people or more, a travel agency will organize the excursion.
The cost is $300 per person, if the group has exactly 25 participants. However, the cost per person drops by $10 for each additional person beyond the calculated maximum of 25.
R(X) = ( 25 + x ) ( 300 - 10x ) ( 300 - 10x )
evaluate in relation to x = R'(X) = 300 - 10x - 250 - 10x = 50 - 20x
We now have 30 people, which means that there are 5 more persons than 25.
Marginal revenue equals $50 when x = 5 and R'(X) = 50 - 20(5).
The revenue will drop by $50 for the following individual (31st ).

if m, p, and t are distinct positive prime numbers, then m3pt has how many different positive divisors greater than 1 ?
Answers
There are 15 different positive divisors (greater than 1) for the number m³pt. Here m, p, and t are distinct prime numbers. This is obtained by the prime factorization method.
How to find the number of positive factors for a number?The following are the steps to find the number of positive factors of a number:
Step 1: Find the L.C.M of the number by using the prime factorization method. For example: consider the number 24. Then, its prime factorization is as follows:
24 = 2 × 2 × 2 × 3
Step 2: Same bases should be added in powers. So, the factors we can write as
24 = 2³ × 3¹
Step 3: To find the number of positive factors of the number, the exponents of the prime factors is multiplied by adding 1.
I,e., N = (3 + 1)(1 + 1) = 4 × 2 = 8.
So, there are 8 factors for the number 32. They are 1, 2, 3, 4, 6, 8, 12, and 24.
Calculation:It is given that, m, p, and t are distinct positive prime numbers.
Then, the number of positive divisors greater than 1 for the number m³pt are
m³× p × t
Since m, p, and t are prime factors, we can multiply their power by adding 1 to them. I.e.,
N = (3 + 1) (1 + 1) (1 + 1) = 4 × 2 × 2 = 16
So, there are a total of 16 factors for the given number (including 1). So, the number of factors greater than 1 is 16 - 1 = 15.
Therefore, there are 15 different positive divisors greater than 1 for the number having prime factors as m³pt.

Answers
The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the lengths of the other two sides. In this case, the length of the hypotenuse is the distance from the dock to the boat, and the lengths of the other two sides are 8 km and 13 km.
If we call the distance from the dock to the boat "d," the equation that represents the Pythagorean theorem in this situation is d^2 = 8^2 + 13^2. Solving this equation, we find that d = 15 km. This means that the boat is 15 km from the dock.

⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
The point on the line are (8, 2).
And, The slope of perpendicular line is,
⇒ m = - 4
Now,
Since, The equation of line passes through the point (8, 2).
So, We need to find the slope of the line.
Since, The product of slope of the perpendicular line is - 1.
Hence, Slope of the line is,
m = - 1/- 4
m = 1/4
Thus, The equation of line with slope 1/4 is,
⇒ y - 2 = 1/4 (x - 8)
⇒ y - 2 = 1/4 (x - 8)
⇒ y - 2 = 1/4x - 2
