Answer:

71.7 degrees

Step-by-step explanation:

So the maximum number of edges in an undirected graph with 100 vertices is 4950.

In an undirected graph, each edge connects two vertices, and as such, it is counted twice, once for each vertex it connects. Therefore, the total number of edges in the graph is the sum of the degrees of all vertices, divided by 2.

In a complete graph with n vertices, every vertex is connected to every other vertex, except itself, and so the degree of each vertex is n-1 (it is connected to n-1 other vertices). Therefore, the total number of edges in the graph is:

n * (n-1) / 2

Substituting n = 100, we get:

100 * 99 / 2 = 4950

Answer:

Every parabola has a turning point called the axis of symmetry,so for this question you just have to find the turning points

x turning point= -b/2a,and the y turning point is gotten by replacing the value of x in the equation

y=(x+1)(x-4)

=x^2-3x-4

a is 1,b is -3 and c is -4

x= -(-3)/2(1)

=1.5

and y=x^2-3x-4

=1.5^2-3(1.5)-4

= -6.25

therefore the axis of symmetry is (1.5,-6.25)

Answer:

17/12

Step-by-step explanation:

find a common denominator for each number so 8/12 and 9/12

Answer:

the third one

Step-by-step explanation:

The general solution to the differential equation y'' + 16y = 0 is y(x) = (c₁ + c₂) * cos(4x)

To solve the differential equation y'' + 16y = 0 using reduction of order, we'll assume a second solution of the form y₂(x) = u(x) * y₁(x), where y₁(x) is a known solution and u(x) is an unknown function.

Given y₁(x) = cos(4x), we'll differentiate it to find y₁'(x) and y₁''(x):

y₁'(x) = -4sin(4x)

y₁''(x) = -16cos(4x)

Now we substitute y₂(x) = u(x) * y₁(x) into the original differential equation:

y'' + 16y = 0

(-16cos(4x)) + 16(u(x) * cos(4x)) = 0

Simplifying the equation:

-16cos(4x) + 16u(x) * cos(4x) = 0

cos(4x)(-16 + 16u(x)) = 0

For this equation to hold for all values of x, we must have (-16 + 16u(x)) = 0.

Solving for u(x):

-16 + 16u(x) = 0

16u(x) = 16

u(x) = 1

Now we have the second solution:

y₂(x) = u(x) * y₁(x)

y₂(x) = 1 * cos(4x)

y₂(x) = cos(4x)

Therefore, the general solution to the differential equation y'' + 16y = 0 is:

y(x) = c₁ * y₁(x) + c₂ * y₂(x)

y(x) = c₁ * cos(4x) + c₂ * cos(4x)

y(x) = (c₁ + c₂) * cos(4x)

Where c₁ and c₂ are arbitrary constants.

Step 2: Subtract 100 from both sides.

25n+100−100=450−100

The derivative of of f(x) = 10 is 0

The derivative of a function is the measure of the rate of change of the function. They are fundamental to the solution of problems in calculus and differential equations.

Here the function is not changing as 10 is a constant. So, if f(x) = c where c is a constant then f'(x) = 0 as the derivative of a constant is always zero.

Mathematically:

           d(f(x))/dx = \(\lim_{h \to 0}\) (f(x+h) - f(x))/h

There  is no x to substitute for x + h so no difference is noticed:

             \(\lim_{h \to 0}\) (f(x+h) - f(x))/h =   \(\lim_{h \to 0}\) (10 - 10)/h = 0

Hence, the derivative of f(x) = 10 is 0

Cat video: exponential function

Dog video: linear function

Step-by-step explanation: I did it until I got it right.

The cat video is a exponential function and dog video is a linear function .

Linear functions are those whose graph is a straight line. A linear function has the following form. y = f(x) = a + bx. A linear function has one independent variable and one dependent variable. The independent variable is x and the dependent variable is y.

An exponential function is a mathematical function of the following form:

f ( x ) = . where x is a variable, and a is a constant called the base of the function. The most commonly encountered exponential-function base is the transcendental number e , which is equal to approximately 2.71828.

For a one-tailed test, the critical value fails to reject the null hypothesis if the test statistic exceeds the critical value. Therefore, the correct option is option 4.

For a one-tailed test, the critical value helps determine if the test statistic falls in the rejection region or not. A critical value is the number of standard errors away from the sample mean. If the test statistic exceeds the critical value, it fails to reject the null hypothesis.

The critical value divides the sampling distribution into two parts. If the test statistic falls in the rejection region, the null hypothesis is rejected. Conversely, if the test statistic falls in the non-rejection region, the null hypothesis is not rejected. The rejection region is determined by the level of significance and the directionality of the hypothesis test.

One-tailed tests are used when the hypothesis test is directional and the researcher only wants to determine if the sample mean is significantly different in one direction from the population mean. Conversely, two-tailed tests are used when the hypothesis test is non-directional, and the researcher wants to determine if the sample mean is significantly different from the population mean in either direction. Hence, the correct answer is option 4.

The equation holds true for any value of a. Therefore, there is no restriction on the value of sin(a). It can be any real number between -1 and 1.

Let's use the given information and the fundamental trigonometric identities to find the exact value of sin(a).

We know that cos(-a) = 4/17 and 17 tan(a) > 0. Since 17 tan(a) > 0, it means that tan(a) is positive. Recall that the tangent function is positive in the first and third quadrants.

Using the fundamental trigonometric identity:

sin^2(a) + cos^2(a) = 1

We can substitute cos^2(a) with (1 - sin^2(a)) and cos(-a) with cos(a):

sin^2(a) + (1 - sin^2(a)) = 1

Simplifying this equation:

sin^2(a) + 1 - sin^2(a) = 1

1 = 1

The exact value of sin(a) is √273 / 17.

To find the exact value of sin(a) given the information:

cos(-a) = 4/17

tan(a) > 0

sin(a) = ?

Let's use the fundamental trigonometric identities to determine the value of sin(a):

We know that cos(-a) = cos(a), so we have:

cos(a) = 4/17

Using the Pythagorean identity, sin^2(a) + cos^2(a) = 1, we can solve for sin(a):

sin^2(a) = 1 - cos^2(a)

sin^2(a) = 1 - (4/17)^2

sin^2(a) = 1 - 16/289

sin^2(a) = 273/289

Taking the square root of both sides, we get:

sin(a) = ± √(273/289)

Since tan(a) = sin(a) / cos(a), and tan(a) > 0, we can determine the sign of sin(a):

When tan(a) > 0, sin(a) and cos(a) have the same sign.

Since cos(a) = 4/17 > 0, sin(a) must also be positive.

Therefore, sin(a) = √(273/289), simplified as:

sin(a) = √273 / 17
