what is the sum of the infinite geometric series?25 minus 10 plus 4 minus eight fifths plus continuing the series diverges.

Answer:

Area = 121pi sq cm

Step-by-step explanation:

Circumference is the distance around the circle. The formula for circumference is:

C = pi•d

The question has the info in it that the circumference is 22pi.

C = 22pi

remember,

C = pi•d this means that the circle has a diameter (the d in the formula is diameter) 22cm.

The radius is half the diameter. The diameter is 22cm, so the radius is 11cm.

The formula for the area is:

Area = pi•r^2

= pi•11^2

= pi•121

= 121pi

The area is 121pi sq cm.

Step-by-step explanation:

100% of 90 is, welll 90, and 50% of 90 is 45, so 150% of 90 is 145

5 - 3 (x - 1) = 4 - 7x, initial equation

5 - 3x + 3 = 4 - 7x, distributing 3 (x - 1) to get 3x + 3

8 - 3x = 4 - 7x, adding 3 to 5 to get 8

8 = 4 - 4x, subtracting 3x from both sides of the equation

x= -1, substituting x for the only possible value to make the equation true.

Answer:

A = pi (r)^2, so first you have to find the radius. The radius = 18.5 since its diameter/2. So if you plug it in, its A = pi (18.5)^2 and your answer would be A = 1075.21. Hope I helped :))

The more coins that are tossed for both gamblers, the less advantageous Gambler A is. But when a few coins are tossed, Gambler A will continue to hold a significant edge.

The binomial distribution;

In probability theory and statistics, the binomial distribution with parameters n and p is used to describe the discrete probability distribution of the number of successes in a set of n independent experiments.

Let X be the number of wins in the first n flips by A, Y be the signal that the last flip by A also wins, and Z be the number of wins in the n flips by B.

As Y is unrelated to X and Z, the following follows:

P(X + Y > Z) = P(Y = 1) P(X ≥ Z) + P(Y = 0) P(X > Z)

= 1/2(P(X = Z) + 2P(X > Z))

P(X > Z) = P(Z > X)

Here,

The less favorable Gambler A is, the more coins are tossed for both players. However, Gambler A will continue to have a sizable advantage even after a few coins are tossed.

The distance between the base of the string and the base of the mast of the sailboat is 6.24.

Here we have to find the distance from the base of the mast that should be attached to the end of the light string.

Data given:

length of the string = 20 foot

length of the mast of the sailboat = 19 foot

Distance between the base of the mast and the light string = [tex]\sqrt{20^{2} - 19^{2} }[/tex]

                                                                                             = [tex]\sqrt{400 - 361}[/tex]

Get the coordinate of X;

X = ax1+bx2/a+b

X = 2(2)+3(2)/2+3

X = (4+6)/5

X = 10/5

X = 2

Get the coordinate of Y:

Y = ay1+by2/a+b

Given any set of seven numbers that should be at least 2 that must have the same remainder when divided by 6

A factor is a number that completely divides another number. To put it another way, if adding two whole numbers results in a product, then the numbers we are adding are factors of the product since the product is divisible by them.

Step 1: factor the provided number into primes, or describe it as the product of primes.

Step 2: Write the prime factorization in exponent form in step three.

Step 3: Increase each exponent by one.

Step 4: Multiply each of the results.

There can only be a maximum of six different remainders when dividing by six: 0, 1, 2, 3, 4, and 5.

In any set of seven integers, two must have the same remainder when divided by seven according to the pigeon hole principle.

b) Consider set of integers 0, 1 ,2, 3, 4, 5 and 66. All these have different remainders upon division by 8 and hence the answer is no.

the straight distance from the origin (0, 0) is the Hypotenuse (the side opposite of the 90° angle).

the coordinate distances in x and y directions are the 2 legs.

Pythagoras :

c² = a² + b²

c being the Hypotenuse, a and b being the legs.

so,

(distance from origin)² = x² + y²

The integral of f with respect to x signifies the area between the graph of f and X-axis. This area would be called definite integral of a function f from a to b. Then Riemannian method of determining this area is:

“if the area is divided into n rectangles of very small breadth, then it would be simpler to calculate the area of such rectangles and then we can add them up

(i ) The width of each rectangle will be denoted as Δx

Δx = b-a/n,

b is upper bound of the integral

(ii) The right-hand endpoints of each rectangle are refer as [tex]x_i[/tex] and we can find the right endpoints by [tex]x_i[/tex] = a + Δx.i

Nulls in a relationship should be avoided as much as possible because of the following reasons:-

• Memory space will be wasted at the storage level

• When aggregate operations such as SUM, AVG etc. are performed on the attribute which has

null value, the result will be incorrect

• When JOIN operation involves an attribute with null values, the result may be unpredictable

• The NULL value has a different meaning. It may be unknown, not applicable or absent

Spurious tuples are generated as the result of bad design or improper decomposition of the base

table.

• Spurious tuples are the tuples generated when a JOIN operation is performed on badly

designed relations. The resultant will have more tuples than the original set of tuples

• The main problem with spurious tuples is that they are considered invalid as they do not

appear in the base tables.

Spurious tuples can be avoided by taking care while designing relation schemas:

• The relations should be designed in such a way that when a JOIN operation is performed, the

attributes involved in the JOIN operation must be a primary key in one table and a foreign key in

another table

• While decomposing a base table into two tables, the tables must have a common attribute. The

the common attribute must be the primary key in one table and the foreign key in another table.

Hence the answer is given.

Green's theorem is theorem about the relationship between a integral line on a simple closed curve C and a double integral of a plane D bounded by C. So, from Green's Theorem we get,

∫Pdx + Qdy = ∫∫([tex]\frac{\partial Q}{\partial x}[/tex]-[tex]\frac{\partial P}{\partial y}[/tex])dA

Put the a and c value into force F equation. So,

F = [2y - 2x]

From this, we get

P = 2y

Q = -2x

[tex]\frac{\partial P}{\partial y}[/tex] = 2

[tex]\frac{\partial Q}{\partial x}[/tex] = -2

So, the integral formula become

∫∫([tex]\frac{\partial Q}{\partial x}[/tex]-[tex]\frac{\partial P}{\partial y}[/tex])dA = ∫∫(-2-2)dA

= -4 dA

Work = -4 × b × d

What do you mean by similar figures?

Two figures are said to be similar if they share the same shape. Congruent objects are those that are precisely the same size and shape.

The term "similar figures" refers to two figures that share the same shape but differ in size.

When two figures are comparable, the sign ‘∼’ is used to indicate that they are.

It is given that Amelia has similar cake pans. The first pan is 10 inches long and 8 inches wide. The second pan is 14 inches long.

We know that the ratio of the sides of the similar figures is always equal,

So , [tex]\frac{10}{8}=\frac{14}{x}[/tex]

where x is the width of second pan.

Solve the above equation using cross multiplication we get,
