The base lengths are (2x + 3) and (x - 4) meters if the area of the base of the statue is 4x² + 12x + 9.

Polynomial is the combination of variables and constants systematically with "n" number of power in ascending or descending order.

[tex]\rm a_1x+a_2x^2+a_3x^3+a_4x^4..........a_nx^n[/tex]

It is given that:

The quadratic polynomial is:

= 4x² + 12x + 9

After using factor method:

= 2x² - 4x + 3x - 12

= 2x(x + 4) + 3(x - 4)

= (2x + 3)(x - 4)

Thus, the base lengths are (2x + 3) and (x - 4) meters if the area of the base of the statue is 4x² + 12x + 9.

The correct option is (x²- 2x + 4) for the quotient.

For the given question;

The equations are given as;

(x³ + 8) = (x + 2)

For finding the quotient; this could be written as,

(x³ + 8)/ (x + 2) = 1

Thus, we have

= (x³ + 8)/ (x + 2)

Rewriting the equation as;

=  (x³ + 2³)/ (x + 2)

Apply the formula of (a³ + b³) = (a+b)(a² - ab + b²) at the numerator;

= (x + 2)(x² -2x + 4)/  (x + 2)

Cancel the value of (x+ 2)

= (x² -2x + 4)

Thus, the quotient of the division is obtained as (x² -2x + 4).

Answer:

50 degrees

Step-by-step explanation:

let's take the triangle to be right angled at b

so b=90                           1                

and c=40 (assumption)   2

so a+b+c=180(angle sum property)

from 1 and 2

a+90+40=180

a=180-130

therefore a=50

Answer:

50

Step-by-step explanation:

90= right side

40= acute side

180 - (90+ 40)= 50.

Step-by-step explanation:

When a point is rotated 180° about the origin(either clockwise or anticlockwise), the transformed coordinates are the negatives of the original coordinates.

Thus when a point (x, y) is rotated about the origin, its new coordinates become (-x, -y)

Given the original 5 vertices of the pentagon, the vertices of the rotated pentagon are transformed as follows

Original Vertex    ==>     Transformed Vertex

(-1, -1)                      ==>          (1, 1)
(-5, -2)                    ==>          (5, 2)
(-6, -4)                    ==>          (6, 4)
(-4, -7)                    ==>          (4, 7)
(-2, -3)                    ==>          (2, 3)

The rate at which the temperature of the compound rose is 2 degree per hour.

To figure this problem we will use unitary method where unitary method is a method where we find the value of the single unit and then multiply the value of single unit to the number of units to get the necessary value.

But according to the question we have find the value of only single unit.

Therefore we have been given that

     every [tex]1\frac{3}{4}[/tex] hours = temperature of compound rose [tex]3\frac{1}{2}[/tex] degrees

Now applying unitary method we get,

         [tex]1\frac{3}{4} = 3\frac{1}{2} \\\\ \frac{7}{4} = \frac{7}{2} \\\\ 1 = \frac{7}{2} /\frac{7}{4}[/tex]

Inverse of the given function F(x) = ( x + 3 )² + 1 is F⁻¹(x) = [√( x - 1 ) ] - 3

Given is a function of x, F(x) = ( x + 3 )² + 1

These question can be solved by following 4 easy steps

Step 1 : Switch the F(x) with the variable y

This implies, F(x) = ( x + 3 )² + 1 becomes y =  ( x + 3 )² + 1

Step 2 : Interchange the variable x and y in the above obtained equation

This implies, from the equation y = 3 x³- 4, we get

x =  ( y + 3 )² + 1

Step 3 : Solve the new obtained equation for y

This implies, we have to simplify the equation by rearranging the terms to get the equation in terms of the variable x.

x = ( y + 3 )² + 1

=> x + 1 =   (y + 3 )²

=> (y + 3 )² = x + 1

=> y = √( x - 1 )  - 3

Hence we obtain the required equation.

Step 4 : Switch the variable y with F⁻¹(x)

This implies, y =√( x - 1 ) - 3 becomes F⁻¹(x) = √( x - 1 )  - 3

Therefore, we get the inverse of the given function F(x) = ( x + 3 )² + 1 as F⁻¹(x) = √( x - 1 )  - 3

The answer to the question is T= - 7.5°C - 8.5°C = -16°C

The initial temperature in the late afternoon was -7.5°C.

It  dropped by 8.5 degrees by midnight.

Change in temperature (in midnight) = -8.5°

Here negative sign represents the decrease in the temperature

.Let T be the total change in the temperature.

So, total change in the temperature is T =  - 8.5°C 

Therefore the required temperature in the midnight =temperature in late afternoon+the temperature dropped in night.

Based on the information, the percentage increase for the area s greater as it is 600% greater

Here, we have a square of side length 3 cm

The area of the square is 3² = 9 cm²

Perimeter of the square = 4L = 4 * 3 = 12 cm

When we triple the length of the square, its new length becomes 3 ,× 3 = 9 cm

Area here will be 9 * 9 = 81 cm²

Perimeter = 4 L = 4 * 9 = 36cm

To calculate percentage change, we use the formula;

(new value - old value)/old value * 100%

For the perimeter;

(36-12)/12 * 100% = 24/12 * 100% = 2 * 100% = 200%

For the area;

(81-9)/9 * 100% = 72/9 * 100% = 8 * 100% = 800%

The percentage increase of the area is greater by: 800% - 200% = 600%

What is Mathematical expression?

The combination of number and variable by using addition, subtraction, multiplication and division is called Mathematical expression.

Given that;

Christopher bought stock in a company two years ago that was worth xx dollars.

In the first year that he owned the stock, then it decreased by 11%.

In the second year the value of the stock decreased by 27%.

Now,

The multiplier of value for the first year was (1 - 11%) = 0.89

The multiplier of value for the second year was (1 - 27%) = 0.73

Then the multiplier of value for the two years was = 0.89 * 0.73

Step-by-step explanation:

the equation of the line that has a slope of 1/5 and passes through (-5, -6) is: y = 1/5x - 5.

Given that the line passes through (-5, -6), and has a slope (m) = 1/5, to find the equation of the line, do the following:

Substitute (x, y) = (-5, -6) and m = 1/5 into y = mx + b to find the value of b:

-6 = 1/5(-5) + b

-6 = -1 + b

Add 1 to both sides

-6 + 1 = -1 + b + 1

-5 = b

b = -5

Substitute m = 1/5 and b = -5 into y = mx + b

y = 1/5x + (-5)

y = 1/5x - 5

Thus, the equation of the line that has a slope of 1/5 and passes through (-5, -6) is: y = 1/5x - 5.

The solution to the inequality expression 22 >= -3x + 7 and -3x + 7 >-17 is -5 <= x  < 8

A number line is a  vertical or horizontal line that has endpoints and it is used to represent numbers at a constant interval

The expression is given as

22 >= -3x + 7 and -3x + 7 >-17

The above expression is an inequality expression

As a general rule:

Inequality expressions are mathematical statements that are represented by variables, coefficients and operators where the opposite sides are not equal

So, we have

22 >= -3x + 7 and -3x + 7 >-17

Evaluate the like terms

15 >= -3x  and -3x  >-24

Divide through by -3

So, we have

-5 <= x  and x  < 8

Combine the expressions

-5 <= x < 8

Hence, the solution to the inequality expression 22 >= -3x + 7 and -3x + 7 >-17 is -5 <= x  < 8
