Hello!

You start with 13 1/4 inches of steel

You cut 2 3/4

So yo subtract these two

13 1/4 - 2 3/4 = 10 2/4

Then you cut 3 1/4 inches off

You subtract these as well

10 2/4 - 3 1/4 = 7 1/4

The answer is 7 1/4

Hope this helps!

Classify each function as even, odd, or neither even nor odd.
drek231 [11]

The function

f(x) is even

g(x) is neither even nor odd

h(x) is odd

Steps:

for an even function it holds that f(-x) = f(x):

f(-x) = (-1)^6 x^6  - (-1)^4 x^ 4 = x^6 - x^4 = f(x) => f is even

for an odd h(x) it holds that h(-x) = -h(x):

h(-x) = (-1)^5x^5-(-1)^3x^3 = -(x^5-x^3) = -h(x) \implies h(x)\,\, \mbox{even}

It is easy to show that g(x) does not match any of the two possibilities above.
