Answer:

TS

Step-by-step explanation:

The general equation of a circle is given by

where (h,k) is the center of the circle and r is the radius

x² + y² -2x - 8y = 8

x² - 2x + y² - 8y = 8

(x² - 2x + ) + (y² -8y + ) = 8

Add square of half of the coefficient of x in the first paenthesis and the half of the square of the coefficient of y in the second parenthesis

Then add the two squaes at the right-hand side of the equation

(x² -2x +1 ) + (y² -8y + 16 ) = 8 + 1+ 16

(x-1)² + (y-4)² = 25

comparing this with the general equation

Center is ( 1, 4)

Radius is 5

This is a problem about combinations where the order doesn't matter. The solution is usually written as 7C2 (seven choose two) and has the value

Comment: 7C2 is the answer to the question "How many pairs (in our case, these pairs are seen as games played) can we form from a group of 7 things?".

Given:

The data set of the monthly rent paid by 7 tenants

990, 879, 940, 1010, 950, 920, 1430

We will find the mean of the data:

Mean = Sum/n

n = 7

Sum = 990+879+940+1010+950+920+1430 = 7119

Mean = 7119/7 = $1017

One of the tenants change from 1430 to 1115

The mean after the change will be as follows:

Sum = 990+879+940+1010+950+920+1115 = 6804

n = 7

Mean = 6804/7 = 972

So, the answer will be:

Mean before the change = 1017

Mean after the change = 972

ANSWER

The sphere is 10762 cubic centimeters bigger than the cube.

EXPLANATION

We want to find the difference in the volumes of the sphere and the cube.

To do this, we have to find the volumes of the sphere and cube and subtract that of the cube from the sphere.

The volume of a sphere is given as:

where r = radius

The radius of the sphere is 15 centimeters. Therefore, the volume of the sphere is:

The volume of a cube is given as:

where s = length of the side

The length of the side of the cube is 15 centimeters. Therefore, the volume of the cube is:

Therefore, the difference in the volumes of the sphere and cube is:

Therefore, the sphere is 10762 cubic centimeters bigger than the cube.

The sum of all the angles in a triangle is always 180°.

We can write the equation and solve for the missing angle:

Solving for x:

The measure of the unknown angle is 72 degrees.

The formula for probabilty is given by; the Probability of an event(A) is the number of favorable outcomes divided by the total number of outcomes possible in a scenario. It can also be denoted by the formula:

In our problem we have 16 trains that are full and 4 which are not, therefore there are a total number of 20 trains in the Westford Station.

The number of favorable outcome is equal to the number of trains that are full since it is the one asked in our question as the one which is more favored to come, according to the question.

Therefore, the number of favorable outcome = number of full trains = 16, and

The Total number of Outcome = total number of trains that may pull over to Westford Station = 20

Therefore the experimental probability that a full train will pull over in the station is;

Therefore there is a probabilty of 4/5 or 80% that a full train will pull over the station.

A) To do that we will draw a line inside the triangle that is perpendicular to the base as I have don above.

B) We will also do the same for B

The polynomial that represents the rollercoaster, using the Factor Theorem, is given as follows:

y = 400(x - 1)²(x + 1)(x² + 0.1)(x + 5).

The Factor Theorem states that a polynomial function with zeros [tex]x_1, x_2, \codts, x_n[/tex], also represented by factors [tex]x - x_1, x - x_2, \cdots x - x_n[/tex] is given by the rule presented as follows:

[tex]f(x) = a(x - x_1)(x - x_2) \cdots (x - x_n)[/tex]

In which a is the leading coefficient of the polynomial function with the given roots.

For this problem, the requirements are as follows:

The roots will be given as follows:

Hence the function is:

y = a(x - 1)²(x + 1)(x² + 0.1)(x + 5).

At x = 0, the function assumes a value of 250, hence the leading coefficient is obtained as follows:

0.5a = 200.

a = 400.

Thus the function is:

y = 400(x - 1)²(x + 1)(x² + 0.1)(x + 5).

Which has the desired features, as shown by the image at the end of the answer.

By means of the area formula for a square, the square has an area of 4 / 49 square meters (approx. 0.0816 square meters).

Herein we find a representation of a solid square in the figure, whose side length measure (l), in meters, is known, and whose area (A), in square meters, has to be found. Dimensionally speaking, the area unit is the square of length unit.  

The area formula of the square is shown below:

A = l²

If we know that the side length of the square has a measure of 2 / 7 meters (l = 2 / 7 m), then the area of the triangle is equal to:

A = (2 / 7 m)²

A = 4 / 49 m²

A ≈ 0.0816 m²

Answer:

Statement 1. AB/DB = CB/EB

Reason 1: Given

Statement 2: ∠ABC = ∠BDE

Reason 2: Vertical angles

Statement 3: ∆ABC~∆DBE

Reason 3: SAS (side - angle - side)

Explanation:

It is given that AB/DB = CB/EB. So, we can say that the ratio of side AB to DB is equal to the ratio of side CB to EB. This made these sides similar.

Additionally, ∠ABC and ∠BDE are vertical angles because they are opposite angles formed when two lines intersect. Vertical angles have the same measure so, ∠ABC = ∠BDE.

Now, we can say that the triangles ABC and DBE are similar by SAS (Side-Angle-Side). Because two sides are similar and the angle between them is congruent.

Therefore, the answer is

Statement 1. AB/DB = CB/EB

Reason 1: Given

Statement 2: ∠ABC = ∠BDE

Reason 2: Vertical angles

Statement 3: ∆ABC~∆DBE

Reason 3: SAS (side - angle - side)

First, notice that the expression for f(f(x)) is the following:

notice that the first term is a quadratic expression with exponent 2. This means that f(f(x)) has 4 zeros.

Since f(x) has 2 zeros (since its quadratic), we have that M-m = 4-2 = 2, thus, M-m will never be 0, 1 or 3

The area enclosed by y² = 8 - x and (y + 1)² = −3 + x is 243.

We are given y² = 8 - x and (y + 1)² = −3 + x.

To sketch and calculate the area enclosed, find the intersection points:

y² = 8 - x ⇒ x = 8 - y²

Substitute x = 8 - y² in (y + 1)² = −3 + x:

(y + 1)² = −3 + 8 - y²

y² + 2y + 1 = −3 + 8 - y²

2y² + 2y - 4 = 0

y² + y - 2 = 0

(y - 1) (y + 2) = 0

y = 1, -2

Substitute y = 1, -2 in x = 8 - y²:

When y = 1, x = 8 - (1) ⇒ x = 7

When y = -2,  x = 8 - (-2)² ⇒ x = 4

Thus, the point of intersection is (4, -2) and (7, 1).

Graph of the region enclosed by y² = 8 - x and (y + 1)² = −3 + x:

Answer

The height of the trapezoid = 3 cm

Explanation

The area of a trapezoid is given as

Area = ½ (a + b) h

where

a and b = base lengths of the trapezoid

a = 9 cm

b = 7 cm

h = height of the trapezoid = ?

Area = 24 cm²

Area = ½ (a + b) h

24 = ½ (9 + 7) h

24 = ½ (16) h

24 = 8h

8h = 24

Divide both sides by 8

(8h/8) = (24/8)

h = 3 cm
