Answer:

[tex]61.8^{\circ}[/tex]

Step-by-step explanation:

Vertical angles are congruent

Answer:

61.8

Step-by-step explanation:

The measure of angle C is 61.8 degrees.

Vertical angles are a pair of nonadjacent angles formed by two intersecting lines. They are called "vertical" because they are opposite each other and share the same vertex (the point at which the two lines intersect). Because vertical angles share the same vertex, they are always congruent, which means that they have the same measure.

In this case, angles C and E are a pair of vertical angles, so they are congruent. Since the measure of angle E is 61.8 degrees, the measure of angle C must also be 61.8 degrees. Therefore, the answer is 61.8 degrees.

The probability states that- (r+w+b+g)min =21,

Probability refers to possibility.

A random event's occurrence is the subject of this area of mathematics. The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

The degree to which something is likely to happen is basically what probability means.

You will understand the potential outcomes for a random experiment using this fundamental theory of probability, which is also applied to the probability distribution.

Knowing the total number of outcomes is necessary before we can calculate the likelihood that a specific event will occur.

According to our question-

r−3=4w,r−2=3b,r−1=2g

r=4w+3,r=3b+2,r=2g+1

rmin=11⇒w min=2⇒bmin​=3⇒g min =5

What is function?

A function from a set X to a set Y in mathematics assigns each element of X exactly one element of Y. The set X is known as the function's domain, and the set Y is known as the function's codomain.

A function is a relationship between a set of inputs and a set of potential outputs, where each input is related to exactly one output.

Given:

Judy purchased a home in 1956.

The function represents y, the value of the home x years since 1956.

f(x) = 11,500(1.09)^x

Let Judy purchased the home for $109,000.

We have to find the the number of years when Judy purchased the home for $109,000.

Plug f(x) = 109,000 in the above equation.

109,000 = 11,500(1.09)^x

218/23 = (1.09)^x

Taking log on both sides,

ln(218/23) = ln(1.09)^x

ln(218/23) = x ln(1.09)

             x = ln(218/23)/ln(1.09)

             x = 26.097

⇒           x ≈ 26

Hence, after 26 years Judy purchased the home for $109,000.

Answer:

A

Step-by-step explanation:

exterior angle = sum of the other two angles

63.25 + 28.8

92.05°

0.9(315 000) * 30(0.0375)

= 283 500 * 1.125

= 318 937.5   (total amount of 30 year mortgage)

= 318 937.5 / 360

= $885.94   (monthly payment)

315 00 * 0.1 = 31 500   (amount of down)

315 000 - 31 500 = 283 500 (balance without interest)

283 500 * 30(0.0375) = 318 937.5  (balance with interest)

318 937.5 / 30(12) = 885.94

Step-by-step explanation:

At any given time there are N people on an elevator, N being a discrete random variable with mean E(N)=n, then E(Y1) = w

Let W be the total weight of all people in the elevator at a given time and N be the number of people in the elevator at a given time.

E(W) = E[E(W|N)]

Since N and Y are independent, we can also write with mean:

E(W|N) = E[E(W|N,Y)]

Since the weight of each person is independent of the others, we can write:

E(W|N,Y) = E[E(W|N,Y1)]

Since Y is a continuous random variable and the weights of each person are independent, we can further write:

E(W|N,Y1) = E(Y1) = w

Therefore, we can conclude that:

E(W) = E[E(W|N)] = E[E(W|N,Y)] = E[E(W|N,Y1)] = E(Y1) = w

As per the limit theorem, the CDF of the standardized variable tends to a limiting value.

The term limit theorem states that the average of a large number of id and the random variables converges to the expected value.

Here we have given that let u1,..., un be independent uniform random variables on [0, 1], and let u(n) be the maximum. find the CDF of u(n) and a standardized u(n).

And we need to prove that the  the cdf of the standardized variable tends to a limiting value.

Let us consider the density function of a uniform random variable on [0,1] is f(x)=1 and the cdf is F(x)=x for x∈[0,1], so for U(n), the density function is

fₙ(x) = nxⁿ⁻¹

Whereas the CDF is written as,

Answer:

(a) To find the range of the function f(x), we need to consider all possible values of x in the range -7 ≤ x ≤ 7 and x ≠ -5. For each value of x, we can evaluate the function to find the corresponding value of f(x). Then, we can find the minimum and maximum values of f(x) in this range to determine the range of the function.

For example, if x = -7, then the function will return a value of 2 - 12/(-7) + 5 = 2 + 2 + 5 = 9. If x = 7, then the function will return a value of 2 - 12/7 + 5 = 2 - 1 + 5 = 6.

We can see that the minimum value of the function is 6, which is achieved when x = 7, and the maximum value of the function is 9, which is achieved when x = -7. Therefore, the range of the function is {6, 9}.

(b) To find the inverse of the function f(x), we need to switch the x and y values in the function definition to obtain a new function g(y) such that g(f(x)) = x for all values of x in the domain of the original function.

In this case, the inverse of the function f(x) is given by g(y) = (2 - y + 5)/(-12). This inverse function is defined for all values of y in the range {6, 9}, which is the range of the original function.

To find the value of f^-1(0), we can plug in 0 for y in the inverse function g(y) to obtain g(0) = (2 - 0 + 5)/(-12) = -1/12. Therefore, f^-1(0) = -1/12.

Answer:

a) [tex]A(x)=360x-2x^2[/tex]

b) [tex]90m[/tex]

c) [tex]16200m^2[/tex]

Step-by-step explanation:

This is related to a differential topic called optimisation.

We here have two sides of the field that are equal to [tex]x[/tex], and another unknown (that we will call [tex]y[/tex]). Maya has 360m of fencing, so we will say that [tex]2x+y=360[/tex], and this means that [tex]y=360-2x[/tex].

Our first task is to find a function for the area of the field. We know that the area of a field is length × width. We know we have a length of [tex]y[/tex] which is [tex]360-2x[/tex] and a width of [tex]x[/tex], therefore:

[tex]A(x)=x(360-2x)=360x-2x^2[/tex]

To find the maximum value of [tex]x[/tex], we must first differentiate the function:

[tex]A'(x)=360-4x[/tex]

We must then set the equation equal to 0 and solve for [tex]x[/tex], where the line/curve would be stationary.

[tex]360-4x=0[/tex]

[tex]4x=360[/tex]

[tex]x=90[/tex]

Finally, to find the maximum area, we would substitute this value of [tex]x[/tex] back into the original equation:

[tex]A(x)=360x-2x^2\\\\A(90)=360(90)-2(90)^2\\\\A(90)=16200[/tex]

For the following:

(a) To find a function A(x) that gives the area of the field in terms of x, use the information given about the fencing and the shape of the field.

Let the length of the other two sides (perpendicular to the side with length x) be y (in meters).

The perimeter of the rectangle is given by the sum of all four sides:

Perimeter = 2x + 2y

According to the problem, the perimeter is 360 meters, set up an equation:

2x + 2y = 360

Now, solve this equation for y in terms of x:

2y = 360 - 2x

y = (360 - 2x) / 2

y = 180 - x

The area A(x) of the rectangle is given by the product of its length (x) and width (y):

A(x) = x × y

A(x) = x × (180 - x)

(b) To find the side length x that gives the maximum area for the field, maximize the function A(x) from part (a). To do that, take the derivative of A(x) with respect to x, set it equal to zero, and solve for x:

A(x) = x × (180 - x)

dA/dx = (180 - x) - x

dA/dx = 180 - 2x

Now, set dA/dx = 0 and solve for x:

180 - 2x = 0

2x = 180

x = 90

So, the side length x that gives the maximum area is 90 meters.

(c) Now there is the value of x, find the maximum area by substituting x = 90 into the area function A(x) from part (a):

A(x) = x × (180 - x)

A(90) = 90 × (180 - 90)

A(90) = 90 × 90

A(90) = 8100

The maximum area that the field can have is 8100 square meters.

Answer:

Step-by-step explanation:

You want the graphs of the given lines, and the centroid of the triangle they form.

It works well to start by plotting the y-intercept of each equation, then using the slope to identify the "rise" and "run" to another point on the line. Then the line can be drawn through the points.

The graph shows you the points of intersection of the lines are ...

  (-4, 2), (4, 8), (0, -4) . . . . . . . . . the last is the y-intercepts of y1 and y3

The centroid coordinates are the average of the vertex coordinates, their sum divided by 3.

  centroid = ((-4, 2) +(4, 8) +(0, -4))/3 = (-4+4+0, 2+8-4)/3 = (0, 6)/3

  centroid = (0, 2)

Additional comment

The slope of each line is the x-coefficient in the equation. That slope is the ratio of "rise" (change in y) to "run" (change in x) for the line. It is often convenient to draw a graph by finding points on the line counting the grid squares for rise and run.

The kinetic energy of an electron that passes undeviated through perpendicular electric and magnetic fields if E=0.18 kV m and B=1.1 mT is 0.07623125 eV.

In the given question, the charge on an electron is 1.60218 x 10^(-19) C and its mass is 9.10939 x 10^(-31) kg.

We have to find the kinetic energy of an electron that passes undeviated through perpendicular electric and magnetic fields if E=0.18 kV m and B=1.1 mT.

E = 0.18 kV/m

B = 1.1 mT

mass m = 9.10939*10^(-31) kg

Then force on a moving charge in electric and magnetic field = Lorentz force

F = qE+ q*VB

So,

F = qE+ q*VB = 0

E = V*B

Find V , so

V = E/B

V = 0.18*10^3 /( 1.1*10^-3)

V =163637 m/s

so KE = 1/2*m*v^2

Then put values..

KE = 0.5*9.11*10^(-31)*163637^(2)

KE = 1.2197*10^(-20) J

in eV = 1.2197*10^-20 / ( 1.6*10^-19 )

eV = 0.07623125 eV

Hence, the kinetic energy of an electron that passes undeviated through perpendicular electric and magnetic fields if E=0.18 kV m and B=1.1 mT is 0.07623125 eV.
