Step-by-step explanation:

Anissa's monthly mortgage payment will be $749.44.

The amount that the lender charges the borrower over and beyond the principal amount is referred to as the interest rate. A person who deposits money in a bank or other financial institution also gets additional income in terms of the recipient, known as interest, taking into account the time value of money.

In this case, we need to find the EMI - Equated Monthly Installments, Anissa has paid.

EMI = P*(1+r)^n / [(1+r)^n -1]

The Principal amount is P = $125,000.

The interest rate is, r = 6% p.a. = 0.005 per month.

The number of periods is, n = 30 × 12 = 360

The monthly payment is:

EMI = P*(1+r)^n / [(1+r)^n -1] = 3764.11/5.023 = 749.4381 = 749.44(approximately)

Thus, Anissa's monthly mortgage payment will be $749.44.

The solid volume obtained by rotating the region enclosed by the curves y2=x and x=2y about the line y=-1 is 5.024 units.

Every three-dimensional item requires some amount of space. The volume of this space is measured. Volume is defined as the space occupied by an item inside the confines of three-dimensional space. It is also known as the object's capacity. A 3D object's volume is the amount of actual space it occupies. It is the 3D counterpart of a 2D shape's area. It is measured in cubic units, such as cm3. This may be calculated by multiplying its length, height, and breadth. Volume is the measurement in cubic units of the three-dimensional space filled by matter or contained by a surface. The cubic meter (m3), a derived unit, is the SI unit of volume.

Here,

It turns out

(R(y)outer) → x = 2y [Equation 1]

(R(y)inner) → y^2 = x [Equation 2]

Set equations equal by substituting Equation 1 into Equation 2 for x:

y^2=(2y)

Solve for y to determine your lower and upper bounds:

y^2 – 2y = 0 → y(y - 4) = 0

y = 0 and y = 2 {We now have our lower & upper bound}

Now we have our equation: V = ∫ π [ (2y)^2  – (y^2)^2] dy  {Integral bounded from 0 to 2}

Lower bound = 0 so it'll make entire expression 0

After plugging in 2 into y and simplifying:

V=π(y³-1/5*y^5)

V=π(8-1/5*32)

V=3.14*(8-6.4)

V=3.14*1.6

The entropy of X is given by

H(X) = −p log p − (1 − p) log(1 − p) = H(p)

The entropy does not depend on the values that the random variable takes (0 and 1 in this case), but only depends on the probability distribution p(x).

The joint entropy is given by

H(X, Y ) = ∑p(x, y) log p(x, y).

The joint entropy measures how much uncertainty there is in the two random variables X and Y

taken together.

The conditional entropy of X given Y is

H(X|Y ) = ∑p(x, y) log p(x|y) = −E[ log(p(x|y))

Step-by-step explanation:

Answer:

Step-by-step explanation:

C. Cheetah B has a higher ratio of miles per minute than Cheetah A because 18 over 16 is greater than 54 over 50.

The correct statement is that f′(−1.1) is less than f′(0.5) which is less than f′(1.4).

The derivative of a function, denoted by f′(x), is the rate at which the function value changes with respect to a change in the independent variable. In this case, the function is given by f(x) = 17x7 − 76x6 + 3x5 − 54x4 − 163x3 + 6x2. So, the derivative of this function can be computed as follows:

f′(x) = 119x6 − 456x5 + 15x4 − 216x3 − 489x2 + 12x

Now, let's evaluate the derivative for x = −1.1, 0.5, and 1.4. Firstly, for x = −1.1,

f′(−1.1) = 119(−1.1)6 − 456(−1.1)5 + 15(−1.1)4 − 216(−1.1)3 − 489(−1.1)2 + 12(−1.1)

= −1709.085

Next, for x = 0.5,

f′(0.5) = 119(0.5)6 − 456(0.5)5 + 15(0.5)4 − 216(0.5)3 − 489(0.5)2 + 12(0.5)

= 112.75

Finally, for x = 1.4,

f′(1.4) = 119(1.4)6 − 456(1.4)5 + 15(1.4)4 − 216(1.4)3 − 489(1.4)2 + 12(1.4)

= −914.56

So you use 73.02 minutes of talk time each month.

Cell phone is a portable electronic device that allows you to make calls, send messages, and perform various tasks such as browsing the internet.

Let x be the number of minutes of talk time you use each month.

The cost for the talk time each month is 19.80 + 0.09(x - 500), and the cost for e-mail is 0.2 * 19.80 = 3.96.

So, the total cost each month is 19.80 + 0.09(x - 500) + 3.96 = 23.76 + 0.09x - 46.04.

The total cost for 7 months is 7 * (23.76 + 0.09x - 46.04) = 166.32 + 0.63x.

We want to find the value of x that makes the total cost equal to $212.31, so we write:

166.32 + 0.63x = 212.31

The volume of the resulting solid as  V = 2π(0)(in e)e = 2πe^2in. can be found by using the method of cylindrical shells.

This method involves calculating the volume of a series of infinitesimally thin cylindrical shells that, when added together, form the solid of interest. The formula for the volume of a single cylindrical shell is V = 2πrhΔx, where r is the radius, h is the height, and Δx is the change in x.

To find the volume of the solid, we must first find the integral of the area of the region bounded by the graphs of y = in x, y = 0, and x = e. This integral can be found by integrating the equation y = in x from 0 to e, which gives us the area of the region. Then, we can use the formula V = 2πrhΔx to find the volume of the solid by substituting the radius of the shell (the radius of the y-axis) for r, the area of the region for h, and the change in x (e - 0) for Δx.

Complete question is shown in figure.

An equation to represent A, the area in square feet, as a function of w, the width in feet is A = 120W -2W²

According to the question, the school uses 120 feet of fencing material to enclose three sides of the play area. This means there are 3 sides.

Substitute into the perimeter of the rectangle will give:

120 = L + 2W

Area = LW

We know that the area of a rectangle is l × w

When w =10, length = 120 - 20 = 100, area = 100 x 10 = 1000

When w = 20, length = 120 - 40 = 80,  area =  80 x 20  = 1600

When w = 40, length = 120 - 80 = 40.  area = 40 x 40 = 1600.

So, the completed table will be

Width            Length          Area

10                    100              1000

20                    80              1600

40                    40              1600  

w                  120 - 2w        (120 - 2w) w

In order to maximize the area with the given fencing, from the equation written above, then w = 30 feet and l = 60

On substituting, we have;

A = LW = (120 - 2W) W

L = 120 - 2W,

In the given triangle,

c = x in

a = 3 in

b = 4 in

Hence,

x^2 = 3^2 + 4^2

x^2 = 9 + 16

x^2 = 25

x = √25

x = 5

The perimeter of a geometric shape is the sum of all its side. Hence,

Perimeter = 3 + 4 + 5 = 12 in

Note: The question is incomplete. The complete question probability is: Using the Pythagorean theorem, find the perimeter of the triangle.
