The perimeter of a rectangle is the total length or distance of its boundary on all sides. The perimeter is 20 unit and area is 21 unit² for vertices of a polygon W(5,−1), X(5, 6), Y(2,−1), Z(2, 6).

The perimeter of a rectangle is the total length or distance of its boundary on all sides. The perimeter of a rectangle is a linear measure and is expressed in linear units of meters, feet, inches, or yards. Let us first understand the two main properties of a rectangle.

All four angles of a rectangle are 90°.

The opposite sides of a rectangle are equal in measure.

The Perimeter of a rectangle = 2(l + w).

given coordinates:

W(5,-1), X(5,6), Y(2,-1), Z(2,6).

Now, considering the coordinates we will find the width and length of rectangle :

Taking points (2,6) and (5,6):

w=5-2=3

Taking  points (5,6) and (5,-1):

l=6-(-1)=7

Now, perimeter of rectangle

= 2x(3+7)

= 20 unit

Hence, area rectangle is : 3x7=21 unit²

Therefore area is 21 unit² and perimeter is 20 units of polygon with the given vertices W(5,−1), X(5, 6), Y(2,−1), Z(2, 6).

This is the same as g(x) which, therefore the functions are inverse of each other.

What does a math inverse mean?

for any point (x, y), that appears in one function, the point (y, x) must appear in the other function. for any point (x, y), that doesn't appear in one function, the point (y, x) must not appear in the other function.  

so if you find any point that doesn't meet the above rules, you can prove that the functions are not inverses of each other.  

to prove that they are inverses of each other, you need to check all points in the functions, and there is an infinity of them, so instead, you can write f(x) like this:  

y = 3x - 5  

solve for x:  

y + 5 = 3x  

x = (y + 5) / 3  

swap x and y:  

y = (x + 5) / 3  

this is the same as g(x) which, therefore the functions are inverse of each other.

The solution to the system of equations is x = 7 and y = -3

Linear equations are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient

A system of linear equations is a collection of at least two linear equations.

In this case, the system of equations is given as

5x + 2y = 29

5x - 2y = 41

Add both equations

So, we have

10x = 70

Divide the equation by 10

So, we have

x = 7

Substitute x = 7 in 5x - 2y = 41

5 x 7 - 2y = 41

This gives

35 - 2y - 41

Evaluate

2y = -6

Divide by 2

y = -3

Hence, the solution to the system of equations is x = 7 and y = -3

Tonya's total earnings are the sum of the basic pay and other commissions so Tonya's earnings for a month including all incentives will be $5450.

The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.

Basic pay of Tonya = $650

3% of 32000 ⇒

3 × 32000 / 100 = $960

Now 8% on higher of $32000

Amount higher of $32000 ⇒ 80000 - 32000 = $48000

So,

8% on 48000 ⇒

8 × 48000/100 = $3840

Total earning = 650 + 960 + 3840 = $5450

Hence "Tonya's total earnings for a month including all incentives will be $5450".

If the binomial (x−7) is a factor of the polynomial function f(x), then the true statement is f(-7) = 0

The given parameters are

The binomial (x + 7) is a factor of the polynomial function f(x)

The above means that

When the function f(x) is divided by x + 7, it has no remainder

So, we have

x + 7

Set to 0

x + 7 = 0

Add -7 to both sides

x = -7

Substitute x = -7 in f(x) = 0

f(-7) = 0

     First add common variables; 7x + x = 8x || -19 + 5 = -14
8x - 14 = 90°
     Second add 14 on both sides;

8x - 14 = 90°

A more straightforward method of dividing a polynomial using a degree one polynomial equation is known as synthetic division.

a simplified method for dividing a polynomial by another polynomial of the first degree by writing down only the coefficients of the several powers of the variable and changing the sign of the constant term in the divisor so as to replace the usual subtractions by additions.

Here,

An L shape is created when a vertical line and a horizontal line are combined.

Within the form, there are two rows of entries.

Entries 2, 10, 1, and 5 are in row 1.

Row 2 has the entries -10, 0 and blank.

On the outside, to the left of the form, is entry number five.

The entry stands for the divisor's zero.

This entry for the variable, let's say x, is [tex]2x^{3} +10x^{2} +x+5[/tex].

Step-by-step explanation:

The values of the variables in the ordered pair are as follows;

18. y = 10

19. x = 6

20. y = -14

21. x = -4

22. x = -5

23. x = 40

24. y = -30

25. y = 5

Ordered pairs are points located on the graph of a function.

In a direct variation, we have;

y = m•x

Where;

m = The slope of the line joining the points

18. (2, -4), (-5, y) the ordered pair is a direct variation

The slope = (y + 4)/((-5) - 2) = (y + 4)/(-7)

y = (y + 4)/(-7) × (-5)

7•y/5 = y + 4

7•y/5 - y = 4

2•y/5 = 4

19. (4, 16), (x, 24)

m = (24 - 16)/(x - 4) = 8/(x - 4)

y = 24

Which gives;

24 = (8/(x - 4))×x

24 × (x - 4) = 8•x

16•x = 96

x = 96/16 = 6

20. (12, y), (4, 7)

m = (7 - y)/(4 - 12) = (7 - y)/(-8)

y = ((7 - y)/(-8)) × 12

12•y/(-8) = 7 - y

12•y = -56 + 8•y

4•y = -56

y = -56/4 = -14

21. (x, -16), (6, 24)

m = (24 - (-16))/(6 - x) = 40/(6 - x)

-16 = (40/(6 - x))×x

16•x - 96 = 40•x

24•x = -96

x = -96/24 = -4

22. y = -18, x = 3

-18 = m×3

m = -18/3 = -6

When y = 30

x = 30/(-6) = -5

23. y = 80 when x = 32

m = 80/32 = 10/4 = 2.5

When y = 100, we have;

x = 100/2.5 = 40

24. y = 10 when x = -4

m = 10/(-4) = -2.5

When x = 12, y = 12 × (-2.5) = -30

25. y = -7 when x = -28

m = -7/(-28) = 1/4 = 0.25

According to basic algebra and the logarithm, the bone is roughly 16384 years old.

Y and t may have the following values: t = 16384, y = 16380. (a). (as determined using logarithm and elementary algebra).

The logarithm is exponentiation's opposite function in mathematics.

The power to which a number must be increased in order to obtain another number is known as a logarithm. This shows that the logarithm of a fixed integer base b represents the exponent to which that number must be raised in order to reach a specific number x.

The logarithm with a base of 10 is the common logarithm, commonly referred to as the value of log base 10. The common logarithm of 10 has a value of 1, or 1.

Let 'a' be the original amount of the object.

Then, according to question, for y = amount of carbon in the object, y = 0.14(a) (as the bone contains 14% of its original carbon-14).

We are also given that: y = a [tex]e^{-0.00012t}[/tex]

On substituting the value of y, we get: 0.14a = a  [tex]e^{-0.00012t}[/tex]

By basic algebra, we can solve it as:

=> 0.14 =  [tex]e^{-0.00012t}[/tex]

=> ln (0.14) = ln ( [tex]e^{-0.00012t}[/tex]) (taking natural logarithm on both sides)

=> ln (0.14) = - 0.00012t (as [tex]log_{b} a^{m} = m log_{b} a[/tex] ; further: [tex]log_{e} e=1[/tex]  )

=>  ln(0.14)/-0.00012= t

=> t = 16384 years (approx.)

The values of y and t can be as follows: t = 16384, y = a (0.9998(16384)) = 16380(a).
