Solution

angle a = c. (opposite angles of 11gm is equal)

put the values of and c

x+45 = 3x-13

now take the variables to the l.H.S and number to R.H.S

x-3x = -13-45

-2x. = 58

x. = 58÷2

x. = 29

angle d + c = 180° (cointerior angle)

y + 3(29) + 13 =180°

y + 100 = 180°

y. = 80

Find a number that can be divided by both 6 and 9, which is 18. That means they will do laundry on the same day every 18 days.

Answer: 18 Days

Step-by-step explanation:

Let's look at their indivigual schedules for hte nex little While

Answer:

B. (13-6) n - 55

Step-by-step explanation:

The number of shirts to be sold is n

The cost to purchase one shirt is $13

The cost of making each shirt is $6

Let's assume the shirt is one

Profit for a Shirt = (13-6)

But then there are no number of shirts

Profit= (13-6)n

But then also, an advert was run for the total shirts combined

Profit= (13-6)n -55

Step-by-step explanation:

FOIL

(x+3y)(x-2y)

F= x²

O= -2xy

I= 3xy

L= -6y²

Add these together = x² + xy - 6y²

Step-by-step explanation:

Hey, there!

Let me simply clear you.

While multiplying algebraic expression, you must be very careful about sign and brackets.

Here,

[tex](x + 3y)(x - 2y)[/tex]

Let's multiply (x-2y) by (x+3y)

[tex] = x(x - 2y) + 3y(x - 2y)[/tex]

[tex] = ({x}^{2} - 2xy) + (3xy - 6 {y}^{2}) [/tex]

Open brackets.

[tex] = {x}^{2} - 2xy + 3xy - 6 {y}^{2} [/tex]

Simplify the like terms.

[tex] = {x}^{2} + xy - 6 {y}^{2} [/tex]

Therefore, the answer is x^2 + xy- 6y^2.

The two equations that represent the remaining angle relationships are (x = 60 - 2(y + z)) and (x = 2z + 20) and this can be determined by using the given data.

Given :

The linear equation that represents the situation "The measure of the largest angle is 60 degrees less than the twice the sum of the measure of the other two angles" is:

x = 60 - 2(y + z)  --- (1)

The linear equation that represents the situation "The largest angle is twice the smaller angle plus 20 degrees" is:

x = 2z + 20  --- (2)

Answer:

The absolute maximum and minimum of [tex]f(x) = 5 + 54\cdot x -2\cdot x^{3}[/tex] on [tex][0,4][/tex] are 113 and 5.

Step-by-step explanation:

Let be [tex]f(x) = 5 + 54\cdot x -2\cdot x^{3}[/tex], the first and second derivatives of the function are, respectively:

[tex]f'=54-6\cdot x^{2}[/tex]

[tex]f''=-12\cdot x[/tex]

Now, let equalize the first derivative to zero and solve the resulting expression:

[tex]54-6\cdot x^{2} = 0[/tex]

[tex]x^{2} = 9[/tex]

[tex]x =\pm 3[/tex]

According to the given interval, only [tex]x=3[/tex] is a valid outcome. Lastly, this is evaluated in the second derivative expression:

[tex]f''=-12\cdot(3)[/tex]

[tex]f'' = -36[/tex]

[tex]x = 3[/tex] leads to an absolute maximum.

[tex]f(3) = 5 + 54\cdot (3) -2\cdot (3)^{3}[/tex]

[tex]f(3) = 113[/tex]

The absolute minimum is determined by evaluating at each extreme of the interval:

[tex]x = 0[/tex]

[tex]f(0) = 5 + 54\cdot (0) -2\cdot (0)^{3}[/tex]

[tex]f(0) = 5[/tex]

[tex]x = 4[/tex]

[tex]f(4) = 5 + 54\cdot (4) -2\cdot (4)^{3}[/tex]

[tex]f(4) = 93[/tex]

The absolute maximum and minimum of [tex]f(x) = 5 + 54\cdot x -2\cdot x^{3}[/tex] on [tex][0,4][/tex] are 113 and 5.

Answer:

find a shorter water-route to Asia.

Step-by-step explanation:

Answer:

θ = 5π/6 rad and 11π/6 rad

Step-by-step explanation:

Given the expression cotθ+√3=0

Subtract √3 from both sides

cotθ+√3-√3=0-√3

cotθ = -√3

Since cotθ = 1/tanθ

1/tanθ = -√3

Reciprocate both sides:

tanθ = -1/√3

θ = tan^-1(-1/√3)

θ = -30°

Since the angle is negative, and tanθ is negative in the second and fourth quadrant.

In the second quadrant;

θ = 180-30

θ = 150°

Since 180° = πrad

150° = 150π/180

150° = 5π/6 rad

In the fourth quadrant;

θ = 360-30

θ = 330°

Since 180° = πrad

330° = 330π/180

330° = 11π/6 rad

Hence the solutions are 5π/6 rad and 11π/6 rad.

Answer:

  z = {1 +i, 1 -i, -1 +i, -1 -i}

Step-by-step explanation:

Using Euler's formula, you can write this as ...

  z^4 = 4e^(i(π+2kπ))

Then the 4th root is ...

  z = 4^(1/4)e^(i(π/4 +kπ/2)) = √2(cos(π/4+kπ/2) +i·sin(π/4+kπ/2))

for integers k in the range 0 to 3.

  z = √2(±1/√2 ±i·1/√2) . . . signs are independent

  z = ±1 ±i . . . . . . signs are independent; hence 4 solutions

  z = {1 +i, 1 -i, -1 +i, -1 -i}

Comment on roots of complex numbers

In the complex domain, each number has a number of roots equal to the index of the root. That is, there are four 4th roots. They all have the same magnitude, but their angles are separated by 360°/(root index) = 90°. Here, the principal fourth root of 4∠180° is 4^(1/4)∠(180°/4) = √2∠45° = 1+i.

Adding 90° is equivalent to multiplying by i, so the other 3 roots are √2∠135° = -1+i, √2∠225° = -1 -i, and √2∠315° = 1 -i.

 z = {1 +i, 1 -i, -1 +i, -1 -i}

Answer:

[tex]4x^3-7x^2-23x-10[/tex]

Step-by-step explanation:

So we have the expression:

[tex](4x+5)(x^2-3x-2)[/tex]

Distribute. Multiply (4x+5) to each term:

[tex](x^2)(4x+5)+(-3x)(4x+5)+(-2)(4x+5)[/tex]

Distribute:

[tex]=(4x^3+5x^2)+(-12x^2-15x)+(-8x-10)[/tex]

Combine like terms:

[tex]=(4x^3)+(5x^2-12x^2)+(-15x-8x)+(-10)[/tex]

Add and simplify:

[tex]=4x^3-7x^2-23x-10[/tex]

Answer:

(0,3)

Step-by-step explanation:

You need to pick a point, P, that will give you a distance from A to P that is twice as long as from P to B, or ration 2:1

Point A is (-2,-7), point B is (1,8), and I picked (0.3) because it looked like it could be, but now we need to test it.

Distance formula is:

[tex]d=\sqrt{(x_{2}-x_{1})^{2} + {(y_{2}-y_{1})^{2} } \\[/tex]

So AP would be

[tex]AP=\sqrt{(0--2)^{2} + {(3--7)^{2} } \\[/tex]

[tex]AP=\sqrt{(2)^{2} + {(10)^{2} } \\[/tex]

Do the same with PB, and you will find it's 5.1, giving an approximate ratio of 2:1.

Answer:

Step-by-step explanation:

If A ⊂ B, that is, A is a subset of B

Also, B ⊂ A, that is, B is a subset A

Therefore, A = B in all respect.

A set is a mathematical model for a collection of items. If two sets are subsets of each other, the other relationship they must have is that they both are equal.

A set is a mathematical model for a collection of items; it comprises elements or members, which may be any mathematical object: numbers, symbols, points in space, lines, other geometrical structures, variables, or even other sets.

If there exist two subsets such that A is a subset of B, also, B is the subset of A. Then the two sets are equal or the same.

Hence, If two sets are subsets of each other, the other relationship they must have is that they both are equal.
