If sin Ф=1/3>0 and tan Ф<0; then Ф belongs to the second quadrant and cos Ф will be negative (cos Ф<0).
sin²Ф+cos²Ф=1
(1/3)²+cos²Ф=1
1/9+cos²Ф=1
cos²Ф=1-1/9
cos²Ф=8/9
cos Ф=⁺₋√(8/9)=⁺₋2√2 / 3
We have two possible solutions.
cos Ф=2√2 / 3 This solutions is not possible, because in this case cos Ф has to be negative (cos Ф<0)
cos Ф=(-2√2) / 3 this solutions is right.
answer:B. -2 square root 2 /3 (or (-2√2) /3 )
1 kg = 2.2 pounds ( rounded to the nearest tenth)
500 kg x 2.2 = 1,100 pounds
1100 pounds is less than 2,500 so the forklift can lift it.
If you meant tens place it's 330 if you meant tenths place it's 325.5

<h3>How to simplify the expression?</h3>
The expression is given as:
Express x^2 - y^2 as (x + y)(x - y) and factorize other expressions
Rewrite the expression as products
Cancel out the common factors
Express 4x^2 - y^2 as (2x - y)(2x + y)
Cancel out the common factors
Take the LCM
Hence, the simplified expression is and the restriction is
