By subtraction, the variable x will eliminate and we will find out the value of y in the given system of equations.

There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.

The equation must be constrained with some constraints.

As per the given system of equations,

2x + 7y = 32 and 2x + y = 8

Subtract both equations from each other,

(2x + 7y) - (2x + y) = 32 - 8

2x + 7y - 2x - y = 24

2x - 2x + 7y - y = 24

6y = 24

y = 4

Hence "By subtraction, the variable x will eliminate and we will find out the value of y in the given system of equations".

Let f:X→Ybe a function. Then the function  f  is a bijection if the relation   {(y ,x)∈Y×X∣ (x ,y)∈f}  is a function.  

Assume that X→Y is a bijective function.  

i.e. f:X→Y is one-one and onto function.

so different elements in X have different images in Y

and b ∈ Y there exists a ∈ X such that f(a)=b.

R= {(y ,x)∈Y×X∣(x ,y)∈f}  is a relation

we wish to prove R is a function.

R is a relation from Y to X  

let  Y∈Y by assumption f is bijection function from X to Y

for all y ∈ Y there exists X∈ X   such that f(x)=y.

so for every element in Y there is mapping element in X.
if (x ,y) ∈  f then (y ,x) ∈ R

therefore R is a function.        

   

let X1, X2, ∈ X then there exists some y1, y2,∈ y such that

take f ( x1 )= y1 and f( x2)=y2

by assumption R is a function from Y to X that is inverse of f is existing means f is bijection.

for bijective functions only inverse exists.

If f:X→Y is a function. Then the function f is a bijection if the relation

{(y ,x)∈Y×X∣(x, y)∈f}  is a function.

The value of p, using the exterior angle property is 53°.

What is the exterior angle property of a triangle?

The exterior angle property of a triangle states that the sum of the measures of the two non-adjacent angles of a triangle is equal to the measure of the exterior angle of the triangle. This means that if a triangle has three interior angles, the measure of any non-adjacent angle of the triangle must be equal to the measure of the exterior angle of the triangle. This property is useful in solving for unknown angles when the measures of two angles are known. For example, if two angles of a triangle measure 30° and 45°, then the measure of the third angle must be 105°, which is the same measure of the exterior angle.

The Exterior angle is = Sum of the Interior opposite angles.

By using the exterior angle property, we can get the following:

p+p-13°=p+40°

=>p=40°+13°

=>p=53°

The value of p is 53°

Hello,

I hope you and your family are doing well!

To solve for V, we can start by subtracting 13 from both sides of the equation:

|v-8| = 16

Since the absolute value of a number is always nonnegative, we know that the value inside the absolute value must be either positive or zero. This means that we have two possible cases to consider:

Case 1: v-8 > 0

In this case, we can drop the absolute value symbols and solve the equation:

v-8 = 16

v = 24

Case 2: v-8 = 0

In this case, we can drop the absolute value symbols and solve the equation:

v-8 = 0

v = 8

So the possible values of V are 8 and 24.

Step-by-step explanation:

|v-8| + 13 = 29

subtract 13 from both sides

|v-8| = 16

form two equations:

v-8 = 16 -(v-8) = 16

v-8 = 16

add 8 to both sides

v = 24

-(v-8) = 16

-v+8 = 16

subtract 8 from both sides

-v = 8

divide both sides by a -1

v = -8

check work:

|v-8| + 13 = 29

|24-8| + 13 = 29

|16| + 13 = 29

29 = 29

|v-8| + 13 = 29

|-8-8| + 13 = 29

|-16| + 13 = 29

|-29| = 29

Therefore ,the radius of the given cylinder is 10 inches

A three-dimensional space's occupied volume is measured. It is frequently expressed as a numerical value using SI-derived units, other imperial units, or US customary units. Volume definition and length definition are connected.

Here,

The volume of the cylinder is 1570 cubic inches

Volume of the cylinder = 1570 cubic inches

Volume of cylinder = π[tex]r^{2}[/tex]h

Where r is the radius of cylinder

h is the height of cylinder

So,

Volume of the cylinder = 1570 cubic inches

=> 1570 = π[tex]r^{2}[/tex]h

=> 1570 = 3.14*[tex]r^{2}[/tex]*5

=> 1570/3.14 = [tex]r^{2}[/tex]*5

=> 500=[tex]r^{2}[/tex]  *5

=> 500/5 =[tex]r^{2}[/tex]

=>100 =[tex]r^{2}[/tex]

=>r=10 inches

Therefore the radius of the given cylinder is 10 inches.

Zero exponent

Simplifying an expression with a 0 as the exponent does not need consideration of the base value.

Any non-zero number multiplied by 0 has the value 1.

x0 = 1, where x = 0 and x = 1, 2, 3, and so forth.

Negative exponent

For any positive integer m and non-zero number a,

a⁻ⁿ=1/a⁻ⁿ

This rule states that if the exponent is negative, it can be made positive by writing the same number in the denominator and writing one for the numerator.

When a number is positive, the exponent shows how many times it has been multiplied by itself.

On the other hand, the negative exponent indicates how many times we must divide the base number. The negative exponent, then, tells us how many times to multiply the reciprocal of the base, to put it another way.

There must be no chance that d and e will happen. If the two occurrences cannot coexist, we can infer that they are not independent.

Simply put, probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of several outcomes. Statistics is the study of events that follow a probability distribution.

P(A) = n(A)/n(S)

Where P(A) is the likelihood that an event "A" will occur and n(A) is the number of positive outcomes. The total number of occurrences in the sample space is denoted by n(S).

We must have a similar probability for both events in order for them to be independent. Because of the table, we may test for independence by knowing the likelihood that e and d will occur. When we are told that occurrences d and e are mutually exclusive, the entire table of values becomes somewhat of a red herring. The chance of d given e and the probability of d given d are both equal to zero if two events are mutually incompatible. There must be no chance that d and e will happen. If the two occurrences cannot coexist, we can infer that they are not independent. There is a chance for it.

The result of the calculation is approximately 22535940185.17

Step-by-step explanation:

To solve this problem, we can use the order of operations. First, we perform the multiplication:

122222 * 2222221 = 2704312822242

Then, we perform the division:

2704312822242 / 12 = 22535940185.17

Step-by-step explanation:

This is a Taylor series because our center is non-zero.

The goal of Taylor series is to approximate non polynomial functions using Calculus.

So let's be intuitive.

In order to be accurate, we need to match the center value at some center a.

We know that cos(pi/2)=0, so our first constant should be 0.

[tex]q(x) = 0[/tex]

Next, we must be spot on with the linear approximation

at x=pi/2

we know that

[tex] \frac{d}{dx} \cos(x) = - \sin(x) = - \sin( \frac{\pi}{2} ) = - 1[/tex]

We also want to divide this by 1! , which is just one so our constant there is

-1, since we want to use this as an linear approximation and we want to be general, and we have a center to stay in respect to,

our next term is

[tex] 0 - 1(x - \frac{\pi}{2} ) {}^{1} [/tex]

Next, up, we must be similar in concavity.

So we take the second derivative of cosine which is just

[tex] - \cos(x) = - \cos( \frac{\pi}{2} ) = 0[/tex]

Since our constant is 0, we can skip this, even if we divide by 2!

Our fourth term is the third derivative of cosine

which is

[tex] \sin(x) = \sin( \frac{\pi}{2} ) = 1[/tex]

We then divide that by 3!, which becomes

[tex] \frac{1}{6} [/tex]

since we want to use this as an cubic approximation and we want to be general, and we have a center to stay in respect to,

our next term is

[tex] - (x - \frac{\pi}{2} ) {}^{} + \frac{1}{6} (x - \frac{\pi}{2} ) {}^{3} [/tex]

Let do one more term,

we know the 5th term is the fourth derivative of cosine evaluated at x=pi/2, which is just 0 so we can skip it.

The 6th term is the fifth derivative of cosine evaluated at x=pi/2, which is -1, then we divide by 5!, so we get

[tex]q(x) = - (x - \frac{\pi}{2} ) + \frac{1}{6} (x - \frac{\pi}{2} ) {}^{3} - \frac{1}{120} ( x - \frac{\pi}{2} ) {}^{5} [/tex]

Using the approximations, plug in 1.5 for x and we get approximately

0.0707
