Answer:

square the whole equation

Step-by-step explanation:

so, it will change from (3x + 7y)² to 9x² - 49y²

I hope this helps a little bit.

Answer:

(3x - 7y)

Step-by-step explanation:

we know that

.. (a + b) (a - b) = (a^2 - b^2)

=> (a + b) = (3x + 7y)

=>. (a^2 - b^2) = (9x^2 - 49y^2)

=> so, (a - b).= (3x - 7y)

hope it helps

Answer:

15% de los niños solo ven dibujos animados, 22.5% solo ven películas animadas, 27.5% ven programas sobre animales, 19% miran programas sobre animales y dibujos animados, y 16% ve los tres tipos de programas.

Step-by-step explanation:

Dado que en una encuesta a 200 niños sobre el programa de TV que más les gusta ver se encontró que 30 niños ven dibujos animados, 45 niños miran películas animadas, 55 niños miran programas sobre animales, 38 niños miran programas sobre animales y dibujos animados y 32 niños miran los tres tipos de programas, para determinar el porcentaje de cada grupo​ se deben realizar los siguientes cálculos:

30/200 = 15/100 = 15%

45/200 = 22.5/100 = 22.5%

55/200 = 27.5/100 = 27.5%

38/200 = 19/100 = 19%

32/200 = 16/100 = 16%

Así, 15% de los niños solo ven dibujos animados, 22.5% solo ven películas animadas, 27.5% ven programas sobre animales, 19% miran programas sobre animales y dibujos animados, y 16% ve los tres tipos de programas.

Answer:

Exponential growth; 40%

Step-by-step explanation:

Just to explain,

the equation A(t)=P(1+r)^t is the standard equation for exponential growth

what youre looking at is the 'r' portion which is the .4 in that equation

to get your percent from the decimal, move the decimal to the right 2 places to go from .40 to 40%

Substitute the values of angles P and Q in an equation that equals 90 degrees

62° + 4x = 90°

Then isolate the variable by first subtracting 62 from both sides

62 + 4x = 90           →    4x = 28

-62           -62

Then divide both sides by 4

4x = 28               →  x = 7

Answer:

y=−2x+7

Step-by-step explanation:

The other moron doesn't understand simple math.

An equation of the line that passes through the point (7,-7) and is perpendicular to the line x - 2y = 2 will be  2x + y = 0.

We have the given line x - 2y = 2 which is in form ax + by = c As we know that slope of line ax + by = c will be -(a/b).

Therefore For given line x -2y = 2 value of a will be 1 and value of b will be -2. Therefor Slope of given line will be -(a/b) = -(1/-2) = 1/2.

Now As we know that slope of two lines which are perpendicular to each other has product of there slopes as negative of unity that is -1.

Let the slope of line which we have to find be m also we have slope of given line as 1/2.

∴ m(1/2) = -1

∴ (m/2) = -1

∴ m = -1(2)

∴ m = -2.

Now as we know that line passes through the point given as (7,-7) and has slope m = -2.

Therefore equation of a line passing through a point (x₁, y₁) and have slope m will be given as

  y - y₁ = m(x - x₁)

∴ y - (-7) = -2(x - 7)

∴ y + 7 = -2x -(-7)

∴ 2x + y = 7 - 7

∴ 2x + y = 0

The descending values of the numbers is 0.98 > 0.925 > 0.88 > 0.7

Given data ,

Let the numbers be represented as A

Now , the value of A is

A = { 0.98 , 0.925 , 0.88 , 0.7 }

And , arranging in the descending order means from the greatest to the least value

So , the value of A is 0.98 > 0.925 > 0.88 > 0.7

Hence , the descending order is 0.98 > 0.925 > 0.88 > 0.7

Answer:

1105.84 in³

Step-by-step explanation:

The volume of the wheel can be obtained using the formular for the volume of a cylinder :

V = πr²h ;

Height, h = 5.5 in

Radius, r = 8 in

V = π * 8² * 5.5

V = π * 64 * 5.5

V = π * 352

Volume of wheel = 1105.8406 in³
