A 10-foot ladder leans against the side of a house with its base 2.2 feet from the house. Use the Pythagorean Theorem to approxi

sergejj [24]

Answer:

Ladder reaches 9.76 high.

Step-by-step explanation:

From the figure attached,

Ac is the ladder which reaches at the point A when leans against the side of a house.

Length of the ladder = 10 feet

Distance of the ladder form the base of a house = 2.2 ft

By Pythagoras theorem,

AC² = AB² + BC²

(10)² = h² + (2.2)²

h² = 100 - 4.84

h = √95.16

h = 9.755 feet

≈ 9.76 feet

Therefore, the ladder reaches the 9.76 high.

The polynomial x3 + 8 is equal to (x + 2)(x2 – 2x + 4). (x – 2)(x2 + 2x + 4). (x + 2)(x2 – 2x + 8). (x – 2)(x2 + 2x + 8).

Maslowich

$Use\ a^3+b^3=(a+b)(a^2-ab+b^2)\\\\x^3+8=x^3+2^3=(x+2)(x^2+2x+2^2)\\\\=\boxed{(x-2)(x^2+2x+4)}$

Which transformation of f(x) will produce the same graph as g(x)?

Vera_Pavlovna [14]

g(x) =f(x) +3

given f(x) =3x

i.e. g(x) =3x+3

For F(x) to be same as g(x)

3 must be added to f(x)

i.e. h(x) =3x+3

->h(x)= 3x +3(1)

-> h(x) = f(x) +f(1)

-> h(x) =f(x+1)

Hence Option (a) is your answer...

Hope it helps...
