Answer 1

Answer:

[tex](x - y)(x + y + 1)[/tex]

Step-by-step explanation:

[tex]x(x + 1) - y(y + 1)[/tex]

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

Lets re-arrange it.

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

Now , lets expand x² - y².

[tex]=> (x + y)(x - y) + (x - y)[/tex]

Taking ( x - y ) common ,

[tex]=> (x - y)(x + y + 1)[/tex]

Answer 2

Answer:

[tex]x(x + 1) - y(y + 1) \\ → {x}^{2} + x - {y}^{2} - y \\→( {x}^{2}- {y}^{2}) + (x - y) \\→ (x - y)(x + y) + (x - y) \\→ \boxed{ (x - y)(x + y + 1)}✓[/tex]

(x-y)(x+y+1) is the right answer.

The side length of an equilateral triangle is 6x - 12. Write an expression for the perimeter of the triangle in simplest form.

Answers

Answer:

18x - 36

Step-by-step explanation:

In an equilateral triangle the 3 sides are congruent, then

perimeter = 6x - 12 + 6x - 12 + 6x - 12 ← collect like terms

                = 18x - 36

The required expression would be 18x - 36 for the perimeter of the triangle in simplest form.

What is the perimeter of a triangle?

The perimeter of a triangle is defined as the addition of the lengths of the triangle's three sides.

What are Arithmetic operations?

Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operations is called the arithmetic operator.

* Multiplication operation: Multiplies values on either side of the operator

For example 4*2 = 8

As we know in an equilateral triangle the 3 sides are congruent.

The perimeter of the triangle = 6x - 12 + 6x - 12 + 6x - 12

Combine the likewise terms and we get

The perimeter of the triangle =  18x - 36

Therefore, the required expression would be 18x - 36 for the perimeter of the triangle in simplest form.

A bicycle wheel has outer diameter 32cm. How far will the cyclist travel if the wheel rotates 100π times? Give your answer in kilometres and correct to two decimal places.

Answers

Answer:

[tex]T=0.3142km \\T=0.31km\ to\ 2dp[/tex]

Step-by-step explanation:

Diameter [tex]d=32cm=0.32m[/tex]

Number of rotations [tex]N=100\pi[/tex]

Generally the circumference of the wheel is mathematically given as

[tex]C=2\pi r[/tex]

[tex]C=2\pi (0.32)^2/4[/tex]

[tex]C=1.005309649m[/tex]

[tex]C=1.0m[/tex]

Generally the total distance traveled  T is mathematically given as

[tex]T=N*C[/tex]

[tex]T=100\pi *1m[/tex]

[tex]T=314.1592654m \approx 314.16m[/tex]

Total distance traveled  T in Kilometres

[tex]T=314.1592654m[/tex]

what is the period of the sinusoidal function

Answers

Answer:

10

Step-by-step explanation:

Period is the distance between two consecutive maximum points, or two consecutive minimum points.

On the given graph the period is the distance between maximum points -7 and 3:

3 - (-7) = 10

Answer:

The period of the sinusoidal function is 2π, i.e., the value of the function repeats at every 2π units.

From the origin towards right we can see that the distance traveled between 0 to 2π is 10 units

Therefore, 10 units is the right answer.

imagine you're in a queue to the airport check-in desk if two-thirds of the queue is in front of you and three tenths of the queue is behind you how many people are in the queue​

Answers

2/3 in front x10
3/10 behind x3

20/30 In front
9/30 behind

20/30+9/30= 29/30
30 people are in the queue

Step-by-step explanation:

Let x be the number of people in the queue, including yourself.

We have 2/3 x + 1 + 3/10 x = x.

=> 29/30 x + 1 = x

=> x/30 = 1

=> x = 30.

Hence there are 30 people in the queue.

Answers

Answer:

2/5

Step-by-step explanation:

If you have two point of the form(x_1,y_1) and (x_2,y_2) then the distance between these points is d=√(x_1-x_2)^2+(y_1-y_2)^2

In this case:

d=/(-8-(-6))^2+(-2-2)^2

d=/(-8+6)^2+(-4)^2

d=/(-2)^2+16

d=/4+16

Step-by-step explanation:

Step 1: Multiply both sides by 5.

4(x−2)

5=20

(4(x−2)*(5)*(5)=(20)*(5)

4(x−2)=100

Step 2: Simplify both sides of the equation.

4x−8=100

Step 3: Add 8 to both sides.

4x−8+8=100+8

4x=108

Step 4: Divide both sides by 4.

4x/4=108/4

x=27

Answer:

  y +2 = (1/4)(x +1)

Step-by-step explanation:

The given line is in slope-intercept form:

  y = mx + b

where the slope (m) is -4 and the y-intercept (b) is +13.

For the perpendicular line, we need a slope that is the opposite reciprocal, or ...

  -1/m = -1/(-4) = 1/4

A suitable form for the desired equation is the point-slope form:

  y -k = m(x -h) . . . . . . line with slope m through point (h, k)

For m=1/4 and (h, k) = (-1, -2), the equation of the line is ...

  y +2 = (1/4)(x +1)
