We have to find the value of x from the given equation.

  • (x - 2)(x² - 2x + 2) = 0 is a quadratic equation, so it will have two values.

Step: Write the equation in simplest form.

  • (x - 2)(x² - 2x + 1) = 0

Step: Solve the problem by spiltting method.

  • (x-2)(x² - x -x + 1) = 0
  • (x - 2)(x²-x - x + 1) = 0
  • (x - 2) [x(x - 1) -1(x -1)]
  • (x - 2)[(x-1)(x-1)]

Step: Solve the problem with using algebraic formula.

{x-1](x-1)

Step : We have used a²-b² to solve the problem.

(x-2)(x² - x -x + 1) = 0

(x - 2)(x²-x - x + 1) = 0

(x - 2) [x(x - 1) -1(x -1)]

(x - 2)[(x-1)(x-1)]

Therefore, the possible factorization is (x - 2)[(x-1)(x-1)].

The longest side of the smaller triangle (24) is twice the length of its shortest side (12), so we expect the longest side of the larger triangle (x) to be twice the length of its shortest side (16)

... x = 2×16 = 32 . . . . corresponds to selection C.

F=G m1m2/r^2 solve for G
Alex_Xolod [135]
The way the equation is written 

Solve for G:F = (G m^3)/r^2
F = (G m^3)/r^2 is equivalent to (G m^3)/r^2 = F:(G m^3)/r^2 = F
Divide both sides by m^3/r^2:Answer:  G = (F r^2)/m^3

Considering only the values of β for which (1+cosβ)(1−cosβ)sinβ is defined, which of the following expressions is equivalent to
just olya [345]

The following expressions (1+cosβ)(1−cosβ)sinβ is equivalent to sin³β

<h3>What are Trigonometric Ratios ?</h3>

In a Right angled triangle , trigonometric ratios can be used to determine the value of angles and sides of the triangle.

The trigonometric expression given in the question is

(1+cosβ)(1−cosβ)sinβ

(a+b)(a-b) = a² - b²

( 1 - cos²β)sinβ

By the trigonometric Identity

1-cos²β = sin² β

 sin² β x sin β

sin³β

Therefore Option B is the correct answer.

Given the values of x and y find the exact (fraction) values of all six trig ratios
Anna35 [415]

Answer:

Step-by-step explanation:

Distance of (-3,4) to origin = √((-3)^2+4^2) = 5

sinθ = 4/5

cosθ = -3/5

tanθ = 4/(-3) = -4/3

cscθ = 1/sinθ = 5/4

secθ = 1/cosθ = -5/3

cotθ = 1/tanθ = -3/4
