If f(x) = [xl-5, what is f(8.6)?

Mathematics
1 answer:
Fynjy0 [20]3 years ago
4 0

Answer:

  3 or 4, depending on the intended meaning of [x]

Step-by-step explanation:

Perhaps you mean ...

  \displaystyle f(x)= \lfloor x\rfloor -5\\\\f(8.6)=\lfloor 8.6\rfloor-5=8-5=3

__

On the other hand, perhaps you mean ...

  \displaystyle f(x)=\lceil x\rceil -5\\\\f(8.6)=\lceil 8.6\rceil-5=9-5=4

Greatest Common Factor/Least Common Multiple of 60 and 84? I used the, "ladder method" and I ended up getting 420 as my answer f
ale4655 [162]
Well 12 x 5 = 60 so that one is correct for the GCF. The one for LCM i dont think you got that right. I dont know the answer for that but i do know that when it is wanting a Least Common Mulitple it means it wants the LEAST, lowest number.

A parallelogram has an area of x2 + 9x - 36.
malfutka [58]

Answer:

Step-by-step explanation:

Please use " ^ " to indicate exponentiation:

A = x^2 + 9x - 36.  This factors into A = (x + 12)(x - 3).  We can assume that the length of the parallelogram is x + 12 and that the width is x - 3.

Note that if x = 3 the area becomes zero.  So:  x must be greater than 3, so that the (x - 3) factor is positive.

Example:  If x = 4, then the dimensions of the parallelogram are 4 + 12, or 16, and 4 - 3, or 1.
