X + 52° = 90°

x = 38°

Answer:

Angle 2 is 38 degrees.

Step-by-step explanation:

Complementary means that the 2 angles equal 90. To find angle 2, lets subtract angle 1 from 90. Let x equal angle 2. 90-52=x. 38=x. Angle 2 is 38 degrees.

Answer:

It's the 3rd one using the formula a^{-m} = \frac{1}{a^{m} }

Once you follow that step you need to multiply the exponent of 3 and 6 with the exponent outside the parenthesis..... which is why it's the 3rd one.

. Solve the following quadratic equation both by factoring and by completing the square:
Anika [276]

Answer:

  x = 1 or -3/4

  factoring is easier for me

Step-by-step explanation:

<u>Factoring</u>

We rewrite to ...

  4x^2 -x -3 = 0

We want factors of (4)(-3) = -12 that have a sum of -1. They are -4 and 3. Then the factorization is ...

  (4x -4)(4x +3)/4 = (x -1)(4x +3)

Solutions are values of x that make the factors zero: x = 1, x = -3/4.

__

<u>Completing the square</u>

We start by factoring the leading coefficient from the left side:

  4(x^2 -x/4) = 3

Now, we add the square of half the x-coefficient (inside parentheses):

  4(x^2 -x/4 +1/64) = 3 + 4/64

  4(x -1/8)^2 = 49/16 . . . . . . . . . write as squares

  x -1/8 = ±√(49/64) = ±7/8

  x = 1/8 ± 7/8

  x = -3/4 or +1

__

<u>Preference</u>

In this instance <em>I prefer factoring</em>, because it deals with whole numbers up until the end. It does not involve adding and subtracting fractions. On this page, it takes fewer steps.

If you're unfamiliar with math facts, such as the factors of 12, then the purely mechanical "completing the square" method may be preferable. It does not require anything other than finding half of a number and then squaring that.
