15% of 45 is 0.15 x 45 or 6.75 feet. That's how far the submarine descended in 1 minute. So, in 4 minutes the submarine would be 4 x 6.75 feet down which is 27 feet.
<span>A)there are no such numbers
Integers are rational numbers, so there can't be a number that is irrational and integer at the same time.</span>
I can see why your confused, but the range of the function is <u>y≤−1 or y≥1</u> . The graph of the cotangent function looks like this: The domain of the function <u>y=cot(x)=cos(x)sin(x)</u> is all real numbers except the values where <u>sin(x)</u> is equal to 0 , that is, the values <u>πn for all integers n</u> .
<em>Hope this helps</em>
Have a great day!
