Answer:

1) The polynomial in standard form is f(x) = x³ - 9·x² + 23·x - 15

2) The polynomial in standard form is f(x) = x³ - (2 - 2·i)·x² + 4·i·x

3) The polynomial in standard form is f(x) = x² + (3·i - 3)·x + 2 - 6·i

4) The polynomial in standard form is f(x) = x² - (5 + √5)·x + 6 + 3·√5

Step-by-step explanation:

Given that that the polynomial is of least degree, we have;

The standard form is the form, f(x) = a·xⁿ + b·xⁿ⁻¹ +...+ c

1) The zeros of the polynomial are x = 5, 3, 1

Which gives the polynomial in factored form as_f(x) = (x - 5)·(x - 3)·(x - 1)

From which we have;

f(x) = (x - 5)·(x - 3)·(x - 1) = (x - 5)·(x² - 4·x + 3) = x³ - 4·x² + 3·x - 5·x² + 20·x - 15

f(x) = x³ - 9·x² + 23·x - 15

The polynomial in standard form is therefore f(x) = x³ - 9·x² + 23·x - 15

2) The zeros of the polynomial are x = 2, 0, 2·i

Which gives the polynomial in factored form as_f(x) = (x - 2)·(x)·(x - 2·i)

From which we have;

f(x) = (x - 2)·x·(x - 2·i) = (x² - 2·x)·(x - 2·i) = x³ - 2·i·x² + 2·x² + 4·ix

The polynomial in standard form is therefore f(x) = x³ - (2 - 2·i)·x² + 4·i·x

3) The zeros of the polynomial are x = 2, 1 - 3·i

Which gives the polynomial in factored form as_f(x) = (x - 2)·(x - 1 - 3·i)

From which we have;

f(x) = (x - 2)·(x - (1 - 3·i)) = x² - x + 3·i·x - 2·x + 2 -6·i = x² + 3·i·x - 3·x + 2 - 6·i

The polynomial in standard form is therefore f(x) = x² + (3·i - 3)·x + 2 - 6·i

4) The zeros of the polynomial are x = 3, 2 + √5

Which gives the polynomial in factored form as_f(x) = (x - 3)·(x - (2 + √5))

From which we have;

f(x) = (x - 3)·(x - (2 + √5)) = x² - 2·x - x·√5 - 3·x + 6 + 3·√5

f(x) = x² - 5·x - x·√5 + 6 + 3·√5 = x² - (5 + √5)·x + 6 + 3·√5

The polynomial in standard form is therefore f(x) = x² - (5 + √5)·x + 6 + 3·√5.

Answer:

g(x) = 1/2x² is the correction option.

Hence, option B is true.

Step-by-step explanation:

Please check the attached graph.

It means when we multiply the parent function by a number 'b' which is less than 1, then the parent function f(x) = x² is vertically compressed by b.

Here, the graph is vertically compressed by 1/2, therefore we conclude that g(x) = 1/2x² is the result of vertical compression of the parent function by 1/2.

Therefore, g(x) = 1/2x² is the correction option.

Hence, option B is true.

Answer:

cos B = [tex]\frac{7}{25}[/tex]

tan B = [tex]\frac{24}{7}[/tex]

sin B = [tex]\frac{24}{25}[/tex]

Step-by-step explanation:

In the right triangle, there are three sides and 2 acute angles

The trigonometry functions of one of the acute angles Ф are

In Δ ACB

∵ ∠C is the right angle

∴ AB is the hypotenuse

∵ AC is the opposite side of ∠B ⇒ leg1

∵ CB is the adjacent side of ∠B ⇒ leg2

→ By using the ratios above

∴ cos B = [tex]\frac{CB}{AB}[/tex] , tan B = [tex]\frac{AC}{CB}[/tex] , sin B = [tex]\frac{AC}{AB}[/tex]

∵ CB = 7, AB = 25, AC = 24

∴ cos B = [tex]\frac{7}{25}[/tex]

∴ tan B = [tex]\frac{24}{7}[/tex]

∴ sin B = [tex]\frac{24}{25}[/tex]

Answer:

Step-by-step explanation:

since x>100, then 19-20x and 20-19x would obviously be negative and x-10 would be positive.

Therefore we have (20x-19)-(19x-20)-(x-10) = 20x-19-19x+20-x+10 = 11

Answer:

2 batches

Step-by-step explanation:

A cookie factory uses 1 1/3 barrels of oatmeal in each batch of cookies

The factory used 2 2/3 barrels of oatmeal yesterday

Therefore the batches of cookies that were made yesterday can be calculated as follows

1 batch= 1 1/3 barrels

x = 2 2/3 barrels

Cross multiply

4/3 x = 8/3

x= 8/3 ÷ 4/3

x = 8/3 × 3/4

x= 2

Hence 2 batches will be produced

Answer:

3 3/4 brick house

Step-by-step explanation:

Total bricks bought = 3/4 of a ton

Each brick house uses = 1/5 of a ton

How many brick house can Jamie complete before they have to order more?

Number of brick house Jamie can complete with the available bricks = Total bricks bought / bricks per house

= 3/4 ÷ 1/5

= 3/4 × 5/1

= 15/4

= 3 3/4 brick house

Jamie will complete 3 3/4 brick house before they have to order more bricks

Answer:

The remainder when 3456 is divided by 7 is 6.

5 is the remainder when 3456 is divided by 7

A division is a process of splitting a specific amount into equal parts.

We need to find the  remainder when 3456 is divided by 7

3456/7

3456:7 is a ratio and 3456/7 is also called as fraction.

The number 3456 is called the numerator or dividend, and the number 7 is called the denominator or divisor.

3456 we can write as 3451+5

3451 is divided by 7 which gives 493.

5 is the remainder when 3456 is divided by 7

Hence, 5 is the remainder when 3456 is divided by 7

Answer:

Length of the Rectangle is to be considered as the circumference of the resulting cylinder and the width of the rectangle should be considered as the height of the cylinder only then we get the maximum volume of the cylinder which is 47.77[tex]in^3[/tex]

Step-by-step explanation:

The given dimensions are

Width of the rectangle is  6inches.

Length of the rectangle 10inches.

Now we need to choose in what orientation we need to use the length and the width of the rectangle so that it can be rolled into a rectangle and we get the maximum volume of the resulting cylinder.

so lets consider two cases

CASE-1: width of the rectangle is to be rolled as the circumference of the cylinder and length of the rectangle is to used as the height of the cylinder

 2*pi*r = 6

      r = [tex]\frac{6}{2pi}[/tex]

      r = [tex]\frac{3}{pi}[/tex] Inch

and the height = 10inch.

Volume of the resultant cylinder will be

   = [tex]pi*r^2*h[/tex]

   = [tex]pi*(\frac{3}{pi} )^2*10[/tex]

   = [tex]\frac{9}{pi}*10[/tex]

   = [tex]\frac{90}{pi}[/tex] = 28.662 [tex]in^3[/tex]

CASE-2: When the length of the rectangle is to used as the circumference of the resultant cylinder and the width of the cylinder is used as the height of the cylinder.

2*pi*r= 10

         r =  [tex]\frac{5}{pi}[/tex]

and the height of the cylinder is 6 inch

Now the volume of the cylinder will be

 Volume= [tex]pi*r^2*h[/tex]

              = [tex]pi*(\frac{5}{pi} )^2*6[/tex]

              = [tex]\frac{25}{pi}*6[/tex]

              = [tex]\frac{150}{pi}[/tex] = 47.77[tex]in^3[/tex]

Clearly we have the second case in which the resulting Cylinder will have the maximum volume.

Therefore the CASE-2 will provide the maximum Volume of 47.77[tex]in^3[/tex] to the resulting cylinder in which the length of the rectangle is to be considered as the circumference of the Cylinder and the width of the rectangle is to be considered as the height of the cylinder.

The system of linear inequalities x + 2y ≤ 4 and 2x - y > 0 has (2,1) in its solution set.

The solution set is given as:

[tex](x,y) = (2,1)[/tex]

The above solution set is true for x + 2y ≤ 4 and 2x - y > 0, and the proof is as follows:

Substitute 2 for x and 1 for y in x + 2y ≤ 4 and 2x - y > 0.

So, we have:

[tex]\mathbf{2 + 2\times1 \le 4 }[/tex]

[tex]\mathbf{2 + 2\le 4 }[/tex]

[tex]\mathbf{4\le 4 }[/tex] --- this is true, because 4 is less than or equal to 4

Also, we have:

[tex]\mathbf{2x - y > 0}[/tex]

[tex]\mathbf{2 \times 2 - 1 > 0}[/tex]

[tex]\mathbf{4 - 1 > 0}[/tex]

[tex]\mathbf{3> 0}[/tex] --- this is also true, because 3 is greater than 0

Hence, the system of linear inequalities x + 2y ≤ 4 and 2x - y > 0 has (2,1) in its solution set.
