Step-by-step explanation:

sine typically intercept at (0,0)

cosine starts at an intercept on Y

The graphs of sine and cos trigonometric functions differ by the waves. The graphs are plotted.

What is trigonometric function?

Simply put, trigonometric functions also referred to as circular functions are the functions of a triangle's angle. This means that these trig functions provide the relationship between the angles and sides of a triangle.

A positive cosine trigonometric function graph starts at maximum value, descends to minimum value, and then rises back to maximum value.

When a graph is negative cosine, it starts at the minimum, climbs to the maximum, and then descends back to the minimum.

For a positive sine trigonometric function graph, the graph starts at the midline, rises to the maximum, descends to the midline again until it reaches the minimum, then rises to the midline again to finish.

In the case of a negative sine graph, the graph starts at the midline, descends to the minimum, then ascends to the midline once again until it reaches the maximum, before returning to the midline where it started.

Therefore, graphs of sine and cos differ with respects to wave formed.

Answer: Waffles: Total Number of Students is 21:56. Simplified it would be 3:8.

Step-by-step explanation:

First, you take the total number of students, which in this case is 56, and subtract it from the number of students who want the pancakes. The difference is 21. That is the number of students who want waffles.

The ratio is 21:56. It must be in that order. It is not the Total number of students: waffles, it is waffles: total number of students.

If it must be simplified, find the greatest common factor. In this problem, it is 7. So the simplified version is 3:8.

Power is the probability that a test correctly rejects a false null hypothesis​.

What is probability?

Simply put, probability measures how probable something is to occur. We can discuss the probabilities of various outcomes—how likely they are—whenever we're uncertain of how an event will turn out.

Power is inversely related to the probability of making a type 2 error (β) which is rejecting the alternative hypothesis when it is true.

The equation of power is:

Power=1-β

Answer:

coordinates for vertex are (5, -9)

Step-by-step explanation:

Given

\(a=1\\\\b=-10\\\\c=16\)

using the formula for the x coordinate of the vertex which is \(\frac{-b}{2a}\) it yields:

\(x_{vertex}=\frac{-(-10)}{2}=5\)

We now have the x-coordinates of the vertex, by applying the x coordinate in the equation we get:

\(5^2-(10\times 5)+16\\\\=25-50+16\\\\=-9\)

thus the \(y_{vertex}=-9\)

Thus the coordinates of the vertex should be (5, -9)

Answer:

y=11/3

Step-by-step explanation:

39 = 6(1) + 9y

39 = 6 + 9y

39 - 6 = 9y

33 = 9y

9y = 33/9

y = 11/3

Answer:

y = 11/3

Step-by-step explanation:

Sometimes it's just how things are written that makes them seem super hard.

R = 6x + 9y is the equation, and then they say what to sub in for x and R. So now we have:

39 = 6(1) + 9y

39 = 6 + 9y

subtract 6 from both sides

33 = 9y

y = 33/9, simplified to 11/3

Step-by-step explanation:

The equation of a line that passes through the point (4, 3) and has a slope of 1 / 2 is y = 1 / 2 x + 1.

The equation of a line that passes through a point can be describe as follows:

y = mx + b

where

Therefore, the line passes through (4, 3) and the slope is 1 / 2.

Hence, let's find the y-intercept using (4, 3)

y = 1 / 2 x + b

3 = 1 / 2 (4) + b

3 = 2 + b

b = 3 - 2

b = 1

Therefore, the equation of the line is y = 1 / 2 x + 1.

Answer:

x = -2

Step-by-step explanation:

y + 2x = -1

y = 1/2 x + 4​

y + 2x= -1

(1/2x + 4) + 2x = -1

1/2x + 2x + 4 = -1

5/2x + 4 = -1

5/2x = -5

x = -2

Answer:

x = -2

Step-by-step explanation:

First, we need to represent y in terms of x by using the first equation. If we do this we will get the following...

y + 2x = -1

y = -1 - 2x

Now we substitute the "y" in the second equation with an equal value in terms of "x" that we got in the last equation, and we will get the follolowing equation...

\(y = \frac{1}{2} x + 4\\- 1 - 2x = \frac{1}{2} x + 4\\-2 -4x = x + 8\\-4x - x = 8 + 2\\- 5x = 10\\5x = -10\\x = 10 /5\\x = 2\)

The rate of decay r is -0.139.

A function has an input and an output.

A function can be one-to-one or onto one.

It simply indicated the relationships between the input and the output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

The exponential function \(y = 3.31(0.87)^x\) can be written in the form

\(y = ab^x,\)

where a = 3.31 and b = 0.87.

The formula for the rate of decay for an exponential function in the form

\(y = ab^x\)is r = ln(b)

where ln is the natural logarithm.

In this case,

r = ln(0.87) ≈ - 0.139.

Since r represents the rate of decay as a decimal, the answer is r = - 0.139.

Thus,

The rate of decay r is - 0.139.

The distance from the plane 10x y z=90 to the plane 10x y z=70, we need to find the distance between a point on one plane and the other plane. The distance from the plane 10x y z=90 to the plane 10x y z=70 is 10sqrt(2) units.

Take the point (0,0,9) on the plane 10x y z=90.
The distance between a point and a plane can be found using the formula:
distance = | ax + by + cz - d | / sqrt(a^2 + b^2 + c^2)
where a, b, and c are the coefficients of the x, y, and z variables in the plane equation, d is the constant term, and (x, y, z) is the coordinates of the point.
For the plane 10x y z=70, the coefficients are the same, but the constant term is different, so we have:
distance = | 10(0) + 0(0) + 10(9) - 70 | / sqrt(10^2 + 0^2 + 10^2)
distance = | 20 | / sqrt(200)
distance = 20 / 10sqrt(2)
distance = 10sqrt(2)
Therefore, the distance from the plane 10x y z=90 to the plane 10x y z=70 is 10sqrt(2) units.

The parametric equations of the line l passing through the given point and perpendicular with the plane p is x = 5 - 3t, y = -8 - 3t, and z = 4 - t.

To find the parametric equations of the line passing through point a (5,-8,4) and perpendicular to the plane p described by the equation 1x - 3y + 3z = 6, we need to first find the direction vector of the line.

The normal vector of the plane p is (1,-3,3), since the coefficients of x, y, and z in the plane equation represent the components of the normal vector.

To find the direction vector of the line, we take the cross product of the normal vector of the plane p and any vector that lies on the line. We can choose the vector (1,0,0) as lying on the line, since it is perpendicular to the normal vector of the plane.

Thus, the direction vector of the line is:

(1,0,0) x (1,-3,3) = (-3,-3,-1)

Now we can write the parametric equations of the line in vector form:

r = a + t*d

where r is the position vector of any point on the line, t is a parameter, a is the position vector of the known point on the line (5,-8,4), and d is the direction vector of the line (-3,-3,-1).

So the parametric equations of the line passing through point a (5,-8,4) and perpendicular to the plane p described by the equation 1x - 3y + 3z = 6 are:

x = 5 - 3t

y = -8 - 3t

The function T(n) in terms of the number of operations is:

T(n) = 2n^3 + 3n^2 + 2n + 1 and the asymptotic complexity of the matrix multiplication algorithm is O(n^3).

To analyze the provided pseudo code for matrix multiplication and determine the function T(n) in terms of the number of operations, we need to examine the code and count the number of operations performed.

The pseudo code for matrix multiplication may look something like this:

```

MatrixMultiplication(A, B):

   n = size of matrix A

   C = empty matrix of size n x n

   for i = 1 to n do:

       for j = 1 to n do:

           sum = 0

           for k = 1 to n do:

               sum = sum + A[i][k] * B[k][j]

           C[i][j] = sum

   return C

```

Let's break down the number of operations step by step:

1. Assigning the size of matrix A to variable n: 1 operation

2. Initializing an empty matrix C of size n x n: n^2 operations (for creating n x n elements)

3. Outer loop: for i = 1 to n

- Incrementing i: n operations  

- Inner loop: for j = 1 to n

- Incrementing j: n^2 operations (since it is nested inside the outer loop)

- Initializing sum to 0: n^2 operations

- Innermost loop: for k = 1 to n

- Incrementing k: n^3 operations (since it is nested inside both the outer and inner loops)

- Performing the multiplication and addition: n^3 operations

- Assigning the result to C[i][j]: n^2 operations

- Assigning the value of sum to C[i][j]: n^2 operations

Total operations:

1 + n^2 + n + n^2 + n^3 + n^3 + n^2 + n^2 = 2n^3 + 3n^2 + 2n + 1

Therefore, the function T(n) in terms of the number of operations is:

T(n) = 2n^3 + 3n^2 + 2n + 1

To determine the asymptotic (big O) complexity of the algorithm, we focus on the dominant term as n approaches infinity.

In this case, the dominant term is 2n^3. Hence, the asymptotic complexity of the matrix multiplication algorithm is O(n^3).

Answer:

y = -(2/3)m - 2

Step-by-step explanation:

recall that the general equation of a straight line in slope-intercept form is

y = mx + b

where, m is the slope and b is the y - intercept

here we are given that the y - intercept is -2, hence the equation becomes:

y = mx + (-2)

or

y = mx -2

we are also given that the x-intercept is -3, which means that when y = 0, x = -3 (simply substitute this into our new equation to solve for m)

0 = m(-3) -2

0 = -3m - 2  (add 3m to both sides)

3m = -2  (divide both sides by 3)

m = -(2/3)

hence our equation is now

y = -(2/3)m - 2

The interest rate for the savings account is 5% after 4 years, $20,000 deposited in a savings account with simple interest earned $800 in interest.

We can use the formula for simple interest to solve the problem:

Simple interest = (Principal * Rate * Time) / 100

where Principal is the initial amount deposited, Rate is the interest rate, and Time is the time period for which the interest is calculated.

We know that the Principal is $20,000 and the time period is 4 years. We are also given that the interest earned is $800. So we can plug in these values and solve for the interest rate:

$800 = (20,000 * Rate * 4) / 100

Multiplying both sides by 100 and dividing by 20,000 * 4, we get:

Rate = $800 / (20,000 * 4 / 100) = 0.05 or 5%

Therefore, the interest rate for the savings account is 5%.
