Answer:

(4a3-5a-3)(2a2-7a+3)

Step-by-step explanation:

use 4a3 to multiply everything in the both brackets=

8a⁵-28a⁴+12a³. then use -5a to multiply everthing in the both brackets =

8a⁵-28a⁴+12a³-10a³+35a²-15a. then use -3a to multiply everthing in the both brackets =

8a⁵-28a⁴+12a³-10a²+35a²-15a-6a²-21a-9.then you furthermore solve=

8a⁵-28a⁴+2a³+29a²-36a-9

The value of y such that the amount of fencing needed is 260 meters is 80 meters

The perimeter of a rectangular field is the sum of the side lengths of the field

For all regular quadrilaterals, you add up the side lengths to determine the perimeter

The given parameters are

Width = 50 m

Amount of fencing = 260 m

Length = y

The amount of fencing is the perimeter of the fence

And perimeter is calculated as

P = 2 * (Length + Width)

So, we have

2 * (y + 50) = 260

Divide both sides by 2

So, we have

y + 50 = 130

Subtract 50 from both sides

So, we have

y = 80

Hence, the value of y such that the amount of fencing needed is 260 meters is 80 meters

Step-by-step explanation:

You want the area of polygon FGHJ from its vertices, using some unspecified formula.

We don't know what formula you were given, but one that we like is ...

  [tex]\displaystyle A=\dfrac{1}{2}\left|\sum_{k=1}^n{x_k(y_{k+1}-y_{k-1})}\right|[/tex]

This formula is implemented in the attached spreadsheet. The line marked Area gives half the absolute value of the sum of the numbers above.

For the given points, the formula is computed by the attached spreadsheet. We recommend this approach whenever repetitive math is involved. You will note that repeating the first two point coordinates makes the formula more straightforward.

The area of this 4×3 rectangle is 12 square units.

[tex]f^{-1}[/tex](f(6.022)) is 6.022 and [tex]f^{-1}[/tex](-10) + f(6) is -4

The general evaluation of function is

[tex]f^{-1}[/tex](f(x)) = x

Here we have to find [tex]f^{-1}[/tex](f(6.022))

Therefore [tex]f^{-1}[/tex](f(6.022)) = 6.022

Now we have to find the value of [tex]f^{-1}[/tex](-10) + f(6)

Form the table of values, we have

[tex]f^{-1}[/tex](-10) = -6 and f(6) = -10

So we have

[tex]f^{-1}[/tex](-10) + f(6) = 6 + (-10)

                     = 6 -10

                     = -4

Therefore [tex]f^{-10}[/tex] (-10)+ f(6) = -4

Trigonometry is one of the most important branches in mathematics that finds huge application in diverse fields. The branch called “Trigonometry” basically deals with the study of the relationship between the sides and angles of the right-angle triangle. Hence, it helps to find the missing or unknown angles or sides of a right triangle using trigonometric formulas, functions, or trigonometric identities. In trigonometry, the angles can be either measured in degrees or radians.

In this article, let us discuss the six important trigonometric functions, ratios, trigonometry tables, formulas, and identities that help to find the missing angles or sides of a right triangle.

Trigonometry is one of the important branches in the history of mathematics that deals with the study of the relationship between the sides and angles of a right-angled triangle.

The equation of the line will be x = -6, that is, option B.

Here, we are given that a line passes through point (-6,-9) and perpendicular to y = 1/4

If two line are perpendicular to each other, the product of their slopes is equal to -1.

Here, the slope of y = 1/4 will be 0 as y is a constant value and not changing.

Let the slope of the given equation be m

them m × 0 = -1

m = -1/0

Thus, the slope is not defined, this means that the line will be parallel to x axis of the form x = k.

Now, we know that the line passes through point (-6,-9). This means that if y = -9, x will be -6. But we know that x will take only one value for all values of y.

Thus, the equation of the line will be x = -6, that is, option B.

The equation of the obtained inverse function is y=x/4 - 1/2.

The given function is f(x)=4x+2.

The inverse function is represented [tex]f^{-1}[/tex] with regard to the original function [tex]f[/tex] and the domain of the original function becomes the range of the inverse function and the range of the given function becomes the domain of the inverse function. The graph of the inverse function is obtained by swapping (x, y) with (y, x) with reference to the line y = x.

The inverse function f(x)=4x+2 can be solved as follows:

Now, f(x)=4x+2

⇒y=4x+2

⇒x=4y+2

⇒x-2=4y

⇒y=(x-2)/4

The graph of the function and inverse function is plotted as given below.

From the graph, the coordinates are (0, -0.5) and (2, 0).

Slope = m = (y2-y1)/(x2-x1)

=(0+0.5)/(2-0)

=0.5/2

=1/4

Put, m=1/4 and (2, 0) in y=mx+b

We get, 0=1/4 (2)+b

b=-1/2

Then, the equation is y=x/4 - 1/2

Therefore, the equation of the obtained inverse function is y=x/4 - 1/2.

The x-value that is a solution of the system is x = 3.

Here we have the system of equations:

3x+y+2z= -10

x+5y+2z= -12

-2x+3y = -1

And we want to find the value of x.

Using the third equation we can write y in terms of x:

y = (-1 + 2x)/3

Now we can replace that in the other two equations:

3x + (-1 + 2x)/3 + 2z= -10

x + 5*(-1 + 2x)/3 + 2z= -12

We can simplify thes two to get:

(3 + 2/3)*x + 2z = -10 + 1/3 = -29/3

(1 + 2/3)*x + 2z = -12 +5/3 = -31/3

Now if we subtract these two equations we will get:

(3 + 2/3)*x - (1 + 2/3)*x = -29/3 + 31/3  = 2/3

2x = 2/3

x = (2/3)/2 = 1/3

x = 1/3

The amount of medicine required by a patient weighing 130 pounds is 186 milligrams of medicine.

A ratio is a comparison of two or more numbers that indicates their sizes and amount in relation to each other.

We have,

Patients weighing 195 pounds require 279 milligrams of medicine.

We can write this in ratio as:

= 279 / 195

Now,

We need to have both patients in proportion.

Proportion means their ratios must be equal.

Let the amount of medicine required for the second patient be M.

We have,

279 / 195 = M / 130

We will find M.

(279 x 130) / 195 = M

The width and length of the rectangle are 11 and 13 cm respectively

The perimeter of a shape is the sum of the side lengths of the shape

For all regular quadrilaterals, you add up the side lengths to determine the perimeter

The given parameters about the rectangle are

Perimeter = 37 + Width

Length = Width + 2 i.e. consecutive odd integers, and width is smaller

Rewrite the above equations as

p = 37 + w

l = w + 2

The perimeter of a rectangle is

p = 2 x (l + w)

Substitute p = 37 + w in the above equation

So, we have

2 x (l + w)= 37 + w

Substitute l = w+ 2 in the above equation

So, we have

2 x (w + 2 + w)= 37 + w

Evaluate the like terms in the above equation

So, we have

2 x (2w + 2)= 37 + w

Open the bracket in the above equation

So, we have

4w + 4= 37 + w

Evaluate the like terms in the above equation

So, we have

3w = 33

Divide both sides of the above equation by 3

So, we have

w = 11

Recall that

l = w + 2

So, we have

l = 11 + 2

l = 13

Hence, the width and length of the rectangle are 11 and 13 cm respectively

The correct safe-breaker code is given by 6437346.

It is given that the number is palindrome. Palindrome is a combination of letters or symbols which when written in reverse order gives the same combination of letters or symbols when written in normal order. Let the seven-digit code be given by abcdefg. As it is palindrome therefore, a=g, b=f, c=e, and d=d. Also, first digit is double than third digit that is a=2c.

According to question d=7, c=f-1 and,

b=7-3 = 4.

Since the number is palindrome so b=f. Therefore f=4.

Now, c=f-1 => c = 4-1 = 3, and c = e = 3.

Also, a=2c => a=6.

Thus, the numbers are a=6, b=4, c=3, d=7, e=3, f=4, g=6 and the combination is 6437346.
