Answer:
2.22
Step-by-step explanation:
To get 2 2/9 in decimal form, we basically convert the mixed number to a fraction and then we divide the numerator of the fraction by the denominator of the fraction. Here are the detailed math steps we use to convert 2 2/9 mixed number to decimal form:
Step 1: Multiply the whole number by the denominator:
2 × 9 = 18
Step 2: Add the product you got in Step 1 to the numerator:
18 + 2 = 20
Step 3: Divide the sum from Step 2 by the denominator:
20 ÷ 9 = 2.222222
That's it! The answer to 2 2/9 in decimal form is displayed below:
2 2/9 ≈ 2.22

For cos(2x) * (2cos(x) + 1) = 0, use the double angle identity for cos(2x), which is cos^2 x - sin^2 x = cos^2 x - (1-cos^2) = 2cos^2 x - 1.
So we have (2cos^2 x - 1)(2cos x + 1) = 0. So 2cos^2 x -1 = 0 or x = 0 and 2pi.
For 2sec^2 x + tan^2 x - 3 = 0, use the identity sec^2 x = tan^2 x + 1, so we have
2(tan^2 x + 1) + tan^2 x - 3 = 0 or
<span>2tan^2 x + tan^2 x - 1 = 0 or
</span>3 tan^2 x = 1.
So x = pi/2, pi/2 + pi = 3pi/2.
