let x = 3.141414.....

then 100x = 314.1414....

100x - x = 314.1414.... - 3.141414.....

99x = 311

x = 311/99 or $3\frac{14}{99}$

y = x2 - 6x - 8 Complete the square in the quadratic equation in order to write the equation in vertex form.

Airida [17]

Answer:

y = (x-3)^2 - 17

Step-by-step explanation:

To complete the square, take the middle term bx and divide it in two. Then take the square.

x^2 - 6x - 8 has bx = -6x. Take -6/2 = -3. Square -3^2 = 9.

Now to finish completing the square add 9 and subtract 9 from one side.

y = x^2 - 6x - 8

y = (x^2 - 6x +9) -9 - 8

y = (x-3)^2 - 17

Describe the diagram

Tasya [4]

Answer:

The diagram reprents the 3 sets and the universal set . The shaded portion clearly can be seen as :

$A \cap B \cap C + A - (A \cap B) - (A \cap C) + A \cap B \cap C + C - (C \cap B) - ( C \cap A) + (A \cap B \cap C)$

Shaded region = $3(A \cap B \cap C) + A + C - (A \cap B) - 2(A \cap C) - (C \cap B)$

erica [24]

Answer:

11.55

Step-by-step explanation:

SOH CAH TOA reminds you ...

Tan = Opposite/Adjacent

The angle at lower left is the complement of 60°, so is 30°. Then the side x satisfies the equation ...

tan(30°) = x/20

Multiplying by 20 gives ...

20·tan(30°) = x ≈ 11.55
