CAN SOMEONE GIVE ME A SUPER SIMPLE ANSWER TO THIS!!??

How do you recognize if a binomial is a difference of perfect squares and how is the pattern used to factor the binomial?

Answers

Answer 1

Answer:

A difference of squares has the following form . Any two perfect squares connected by subtraction can be factored.

It factors to (a+b)(a-b).

Step-by-step explanation:

A binomial is an expression with only terms where at least one is a term with a variable. When we can factor for difference of squares, we can have two variable terms or just one with a constant.

A difference of squares has the following form . Any two perfect squares connected by subtraction can be factored.

It factors to (a+b)(a-b).

The population of a town decreases exponentially at a rate of 1.7% per year.
The population now is 250 000. Calculate the population at the end of 5 years
Give your answer correct to the nearest hundred.

Answers

Answer: 229,500 people to the nearest hundred

Step-by-step explanation:

Population decreases exponentially at 1.7% per year in a town that is currently 250,000 in number.

Population in 5 years = 250,000 * ( 1 - 1.7%) ⁵

= 250,000 * 0.917841286185143‬

= 229,460

= 229,500 people to the nearest hundred

Solve the system of equations below

Answers

Answer:

The answer is B. (-7,-2)

Step-by-step explanation:

Multiply the first equation by 7,and multiply the second equation by -6.

7(−3x+6y=9)

−6(5x+7y=−49)

Becomes:

−21x+42y=63

−30x−42y=294

Add these equations to eliminate y:

−51x=357

Then solve−51x=357for x:

−51x=357 Divide both sides by -51

x=-7

Write down an original equation:

−3x+6y=9

Substitute−7forxin−3x+6y=9:

(−3)(−7)+6y=9

6y+21=9(Simplify both sides of the equation)

6y+21+−21=9+−21(Add -21 to both sides)

6y=−12

Step-by-step explanation:

The solution will be obtained when f(x) = g(x)

Mathematically;

x + 1 = x^2-6x-7

x^2-6x-x-7-1 = 0

x^2-7x-8 = 0

x^2-8x + x -8 = 0

x(x-8) + 1(x-8) = 0

(x+1)(x-8) = 0

x = -1

x = 8

so let us get the f(x) and g(x) values

For x + 1

-1 + 1 = 0

8 + 1 = 9

Points are;

The correct potion is B.

What is a vector?

The quantity which has magnitude, direction and follows the law of vector addition is called a vector.

An airplane is flying in the direction of 30 degrees South of West at 600 mph. A wind is blowing in the direction of 60 degrees North of East at 40 mph.

It means the airplane is flying in the opposite direction of the wind.

The component of an airplane will be

[tex]\rm x = - 600\ sin 30\\\\x = - \dfrac{600}{2}= -300\\\\y = -600 \ cos30\\ \\y= -\dfrac{600 \sqrt{3}}{2}[/tex]

The component of wind will be

[tex]\rm x = 40 cos 60\\\\x = \dfrac{40}{2} = 20 \\\\y = 40sin 45\\ \\y= \dfrac{40\sqrt3}{2}[/tex]

Then the ground speed will be

[tex]G = \sqrt{(600\dfrac{\sqrt3}{2} + 20)^2 + (300 + 40 \dfrac{\sqrt3}{2})^2}[/tex]

Then the correct potion is B.

Use a pythagorean triple to the lengths of the hypotenuse of a right triangle if the legs have lengths of 20 units and 48 units

Answers

Answer:

52 units.

Step-by-step explanation:

Use the Triple 5-12-13

20 / 4 = 5

48/ 4 = 12

So  the hypotenuse = 4 * 13 = 52.

The lengths of Hypotenuse 52 units.

What is Pythagoras Theorem?

The Pythagoras theorem states that the square of a triangle's hypotenuse is equal to the sum of its other two sides' squares.

According to the Pythagoras theorem, the square of the hypotenuse of a triangle, which has a straight angle of 90 degrees, equals the sum of the squares of the other two sides.

Given:

The measurement of two sides are 20 units and 48 units.

Now, Using Pythagoras theorem

H² = P² + B²

H² = 20² + 48²

H² = 400 + 2304

H² = 2704

H = 52 units.

Hence, lengths of Hypotenuse 52 units.

Substitute values for GP and TP

[tex]6.4^2 = 6^2 + TG^2[/tex]

[tex]40.96 = 36 + TG^2[/tex]

Answer:

AB = 3 and AC = 4

Step-by-step explanation:

Given that the triangles are similar then the ratios of corresponding sides are equal, that is

[tex]\frac{AB}{WX}[/tex] = [tex]\frac{BC}{WY}[/tex] , substitute values

[tex]\frac{AB}{30}[/tex] = [tex]\frac{3}{30}[/tex] ( cross- multiply )

30AB = 90 ( divide both sides by 30 )

AB = 3

and

[tex]\frac{AC}{XY}[/tex] = [tex]\frac{BC}{WY}[/tex] , substitute values

[tex]\frac{AC}{40}[/tex] = [tex]\frac{3}{30}[/tex] ( cross- multiply )

30AC = 120 ( divide both sides by 30 )

AC = 4

Answer:

AB = 3AC = 4

Step-by-step explanation:

Let AB = xLet AC = y

Given

ΔWXY ~ ΔBAC

Therefore, the triangles are similar, so corresponding sides would be in the same ratio, so

WY/ BC = XW/AB

substitute WY = 30, BC = 3, XW = 30, AB = x

30 / 3 = 30 / x

x = [30 × 3] / [30]

x = 90 / 30

x = 3

Thus,

AB = 3

now

WY/ BC = XY/AC

substitute WY = 30, BC = 3, XY = 40, AC = y

30 / 3 = 40 / y

y = [40 × 3] / [30]

y = 120 / 30

y = 4

Thus,

AC = 4

Therefore,

AB = 3AC = 4

Step-by-step explanation:

Given that:

Number of basic instincts present = 66

Number of choices = 2

Using combination :

66C2 = 66! / (66 - 2)!2!

66C2 = 66! / 64!2!
