18 shells because since Mary has 6 and Tina has 3 shells all you have to do is multiply 6 and 3 to get 18
<span>Tan(x) = sin(x) / cos(x). Therefore, tan(x) pi/2 = 1/0, which doesn't exist. Imagine that, instead of 0, it's a number incredibly close to 0. The smaller the number in the denominator, the bigger the outcome. Therefore, we can think of 1/0 as infinity, or approaching infinity as one gets closer to 1/0. This is the same result approaching from the negative side, only it's negative infinity. If x=0, it's 0/1 instead (sin 0=0, cos 0=1). Anything divided by 1 is itself, so as x approaches 0, so does f(x).</span>
No. 0.2487 is not an interger.
There are two big reasons for this:
1). There is no such thing as an ' interger ',
so no number could be one.
You probably mean ' integer '.
2). An integer is a whole number ... a number
with no fraction part and no decimal part.
0.2847 is all decimal, and not even big enough
to make the smallest whole number. (That's ' 1 '.)
