Answer:

Step-by-step explanation:

cos(t) + i * sin(t) = e^(i * t)

Therefore, (cos(t) + i * sin(t)) / (cos(s) + i * sin(s)) = cos(t - s) + i * sin(t - s)

9 * (cos(135) + i * sin(135)) / (7 * (cos(10) + i * sin(10))) =>

(9/7) * (cos(135 - 10) + i * sin(135 - 10)) =>

(9/7) * (cos(125) + i * sin(125))

The area (in square inches) of a rectangle is given by the polynomial function A(p) = p2 + 9p + 20. If the length of the rectang

boyakko [2]

Answer:

$Width = p + 4$

Step-by-step explanation:

Given

$Area = p^2 + 9p + 20$

$Length = p + 5$

Required

Determine the width

The area of a rectangle is:

$Area = Length * Width$

This gives:

$p^2 + 9p + 20= (p+5)* Width$

Expand

$p^2 + 4p + 5p + 20= (p+5)* Width$

Factorize

$p(p + 4) + 5(p + 4)= (p+5)* Width$

$(p + 5) (p + 4)= (p+5)* Width$

Divide both sides by p + 5

$p + 4= Width$

$Width = p + 4$

Select the correct answer from the drop-down menu. A=-2[-6 4, 3 7, 12 10], B=3[-2 2 8, 8 5 6], 3C=3[-2 8, 2 5, 8 6] and D=-1[-12

max2010maxim [7]

Answer:

A and D are equal

Step-by-step explanation:

Given

$A=-2[-6, 4, 3 ,7, 12, 10]$

$B=3[-2, 2, 8, 8, 5, 6]$

$3C=3[-2, 8, 2, 5, 8, 6]$

$D=-1[-12, 8, 6, 14, 24, 20].$

Required

The equal matrices

First, we simplify the given expressions

$A=-2[-6, 4, 3 ,7, 12, 10]$

Open bracket

$A= [12, -8, -6 ,-14, -24, -20]$

Next:

$B=3[-2, 2, 8, 8, 5, 6]$

Open bracket

$B=[-6, 6, 24, 24, 15, 18]$

Next:

$3C=3[-2, 8, 2, 5, 8, 6]$

Divide by 3

$C=[-2, 8, 2, 5, 8, 6]$

Lastly:

$D=-1[-12, 8, 6, 14, 24, 20].$

Open bracket

$D=[12, -8, -6, -14, -24, -20].$

By comparison:

$A = D=[12, -8, -6, -14, -24, -20].$

THANKS IF YOU ANSWER,

Yakvenalex [24]

ANSWER: 114ft^2

Area of cabinets = (4*2)+(4*2) = 16ft^2

Area of kitchen = (10*13) = 130ft^2

Subtract area of the cabinets from total area

130ft^2 - 16ft^2 = 114ft^2

Plz help will mark as brainleist

Ilia_Sergeevich [38]

Answer: B

Step-by-step explanation:

First, simplify the main expression. The answer is 21.

Then simplify A. It is -106. That is not equal to 21 so A is wrong.

Then simplify B. That is 21. That means B is correct and you don’t have to solve C or D.
