So, the x-intercept is  the point   (5,0).  The distance    between those   points  is

At  a   rate    of  2   units   per second, it  will    take     seconds    to  travel  7.81    units.  That’s  about   3.91.

36 . C
Use the given angle to find the ratio of the legs:

If  you call    AC  (the    leg you’re  looking for)    x,  then    you can call    leg BC  0.781x. Half    the product

of  the legs    is  the area,   or  15:

37 . E

You should  know    what    the ranges  are of  (A) y   =   sin x and   (B) y   =   cos x.  They’re both    −1  ≤   y   ≤   1.

They    both    include −1  and 1   themselves, so  you can eliminate   (A) and (B).    The upper   limit   of

(C) is  1,  but (C) can be  much    smaller than    −1, such    as  when    x   =   −0.99.  So  you can eliminate

(C).    (D) can never   be  less    than    zero    because the numerator   and denominator are

nonnegative for all possible    x.

The answer  is  (E) because as  x   gets    very    large,   approaches  or  ,  so  the value

of  the whole   expression  approaches  1;  and as  x   gets    very    small   (that   is, very    negative),
