Answer 2

Answer:

(a+b) ²≥4ab explanation below↓↓↓↓

Step-by-step explanation:

We know that

(a-b) ²≥0

a²-2ab+b²≥0

Move -2ab to the other side

a²+b²≥2ab

Add 2ab to both sides

a²+2ab+b²≥4ab

(a+b) ²=a²+2ab+b² therefore :

(a+b) ²≥4ab

[tex]a = 8.5t[/tex]

[tex]y = 32.55[/tex]

Step-by-step explanation:

Solving (9): The equation of the table

We start by calculating the slope (m)

[tex]m = \frac{a_2 - a_1}{t_2 - t_1}[/tex]

Where:

[tex](t_1,a_1) = (15,127.5)[/tex]

[tex](t_2,a_2) = (16.5,140.25)[/tex]

[tex]m = \frac{140.25 - 127.5}{16.5 - 15}[/tex]

[tex]m = \frac{12.75}{1.5}[/tex]

[tex]m = 8.5[/tex]

The equation is then calculated using:

[tex]a = m(t - t_2) + a_2[/tex]

So, we have:

[tex]a = 8.5(t - 16.5) + 140.25[/tex]

Open bracket

[tex]a = 8.5t - 140.25 + 140.25[/tex]

[tex]a = 8.5t[/tex]

Solving (10):

[tex]4.8y = 156.24[/tex]

Required

Find x

Divide both sides by 4.8

[tex]y = 32.55[/tex]

What is the purpose of the air in air hockey?

Answers

Answer:

A fan within the center of the table blows air through these holes in order to allow the puck to quickly glide across the table surface. This movement of air is the reason why we call the sport "air" hockey vs. just table hockey. There are two holes at opposite ends of the table that make up a goal.

Answers

Answer:

(-1, -8)

Step-by-step explanation:

So you would do the simplifying by "subtracting" the equations from each other. So to isolate the x, you could subtract the y away.

   8x + y = -16

  -3x + y = -5

-___________

11x = -11

x = -1

Then, substitute x into either equation.

8(-1) + y = -16

-8 + y = -16

Isolate y.

y = -8

Complete arithmetic sequence?

92, ___, ___ ,___, 80

Answers

Answer:

433333333333

Step-by-step explanation:

The complete arithmetic sequence will be 92, 89, 86, 83, and 80.

What is an arithmetic sequence?

Let a₁ be the first term and d be a common difference.

Then the nth term of the arithmetic sequence is given as,

aₙ = a₁ + (n - 1)d

The first term (a₁) is 92 and the fifth term (a₅) is 80.

Then the common difference between the terms will be given as,

a₅ = a₁ + (5 - 1)d

80 = 92 + 4d

-12 = 4d

d = -3

Then the missing terms will be

92, 92 - 3, 92 - 6, 92 - 9, and 92 - 12

92, 89, 86, 83, and 80

Thus, the complete arithmetic sequence will be 92, 89, 86, 83, and 80.

in a film, a character is criticized for marrying a woman when he is three times her age. he wittily replies "ah, but in 20 years i shall only be twice her age." how old is the man and the woman?

Answers

Answer:

W = 20 (woman's age)

M = 60 (man's age)

Step-by-step explanation:

M = Man's age

W = Woman's age

M + 20 = 2(W + 20)

Sub for M

3W + 20 = 2W + 40

W = 20 (woman's age now)

M = 60 (man's age now)

What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Total number of customers = 4,668

Number of customers who sat outside = x

Number of customers who sat inside = 11x

Now,

x + 11x = 4,668

12x = 4,668

x = 389

11x = 11 x 389 = 4279

Thus,

The number of customers who sat outside is 389.

The number of customers who sat inside is 4279.
