Find all the zeros of the equation. 27x2-324=-x4

1 answer:

8 0

Well, if I remember correctly, Zeroes just mean the x values. But I can't tell where your equation breaks apart; like which parts are which parts of the equation

Correct Answer: Option A

The next step in simplification will be to convert the squared term so that it no longer contains a square.

So, we are to simplify the term $cos^{2}(2x)$

Using the half-angle identity we can write:

$cos^{2}(2x)= \frac{1+cos(4x)}{2}$

Using this value, the equation becomes:

$sin^{4}x=1-2cos(2x)+ \frac{ \frac{1+cos(4x)}{2} }{4}$

Therefore, option A is the correct answer.

An equiangular triangle has one angle of measure 2x+8. What is x?

lina2011 [118]

Answer:

$x=26\\$

Step-by-step explanation:

The sum of the interior angles of a triangle add up to $180^{\circ}$ . Therefore, an equiangular triangle will have each of its angles equal to $60^{\circ}}$ . We can then set up the following equation:

$2x+8=60, \\2x=52, \\x=\fbox{$26$}$ .

Wazma bought some new pants, but the 34 inch inseam was too long. If he wants the inseam to be 3013 inches long, how much length

KiRa [710]

The length of the inseam to be removed from the pant is 3 2 / 3 inches.

<h3 /><h3>How to find the length to be removed?</h3>

The length of the pant he bought is 34 inches and it was too long.

He wants the length to be 30 1 / 3 inches long.

Therefore, the amount of length to be removed can be calculated as follows;

34 - 30 1 / 3

$30\frac{1}{3} = \frac{91}{3}$

Hence,

$34-\frac{91}{3}=\frac{102-91}{3} =\frac{11}{3}=3\frac{2}{3} inches$

Therefore, the number to be removed is 3 2 / 3 inches
