What is log squared with a base of 4 with the exponent (x^2+x) and the whole thing is equal to 0.25. Find the domain of x and fi
alexandr1967 [171]

Answer:

X = 1 , -2

Step-by-step explanation:

Given in question as,

(log4(x² + x))² = 0.25

log4(x² + x) = 0.5

Applying log base property if      log(a)X = b,   then X =a^b

Or, x² + x = 4^0.5

     x² + x = 2

     x² + x - 2 = 0

     x²+2x-x-2 = 0

     (x + 2) (x - 1) = 0

So, x = 1 and -2   Answer

9514 1404 393

Answer:

  14.14

Step-by-step explanation:

The diagonal of a square is √2 times the side length.

  AC = AB×√2

  AC = 10√2 ≈ 14.14

_____

The diagonal of a square is the hypotenuse of an isosceles right triangle. If the sides of that are s and the diagonal is d, the Pythagorean theorem tells us ...

  d² = s² + s²

  d² = 2s²

  d = (√2)(√s²) = s√2

This relation holds for <em>any isosceles right triangle</em>, not just for the diagonal of this square. It is useful to remember.
