Answer:

B. 8.

D.  log2 256.

Step-by-step explanation:

Generally:

loga b + loga b

= loga b^2.

Therefore log2 16 + log2 16

= log2 16^2

= log2 256.

From the above:

256 = 2^x   where x is the log.

Now 2^8 = 256   so the original log2 16 + log2 16 = 8.

construct a right-angled triangle ABC where angle A =90 degree , BC= 4.5cm and AC= 7cm. please ans fast........ Very urgent. Pls
Katena32 [7]

Answer and Step-by-step explanation: The described right triangle is in the attachment.

As it is shown, AC is the hypotenuse and BC and AB are the sides, so use Pytagorean Theorem to find the unknown measure:

AC² = AB² + BC²

AB^{2} = AC^{2}-BC^{2}

AB =\sqrt{AC^{2}-BC^{2}}

AB =\sqrt{7^{2}-4.5^{2}}

AB =\sqrt{28.75}

AB = 5.4

Then, right triangle ABC measures:

AB = 5.4cm

BC = 4.5cm

AC = 7cm

PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!!
Yakvenalex [24]

Answer: (C) even

<u>Step-by-step explanation:</u>

A function is even when f(x) = f(-x)

A function is odd when f(-x) = -f(x)


f(x) = -2x⁴ + 3x²

f(-x) = -2(-x)⁴ + 3(-x)²

      = -2x⁴ + 3x²

f(x) = f(-x) so the function is even


-f(x) = -(-2x⁴ + 3x²)

       = 2x⁴ - 3x²

f(-x) ≠ -f(x) so the function is not odd.
