<span>c) sqrt(1-x^2)/x </span>
<span>D) 1/sqrt(1-x^2)
</span>
The answer should be <span>c) sqrt(1-x^2)/x .

</span><span>cos u = sqrt (1 - sin^2 u) = sqrt(1 - x^2), and cot u = cos u / sin u.</span>

Answer:

The total golf balls Jack has now in terms of expression is as below

$a = 3b + 6$

Where a is total number of balls and b is number of balls in each bag.

Step-by-step explanation:

Solution:

let a be the total number of balls and b is the number of balls in each bag.

Number of bags is 3.

So total number of balls before the friend gave is $3\times b$

Now the friend has given him 6 more golf balls then the total number of balls will become 3b + 6.

Therefore, the required expression is

$a = 3b + 6$
