If f(x) = (xm + 9)2, which statement about f(x) is true?

I would say none of these .

for x to be even then f(x) = f(-x) for all values of x in the domain.
Suppose x=1 and m=1 then f(x) = 20. f(-1) is 16 so f(x) does not equal f(-x)

for it to be odd then either f(x) = -f(x) or f(x) + f(-x) = 0 . Looking at teh above example neither is true.

That is an odd value of m . if you use m=2 you have exactly the same effect so its not even or odd for an even value of m.

So unless you've got a very restricted domain for the function none of these statements are true.

Build a fence around his rectangular garden. The length is 30 feet. The width is 6 yards. How many feet of fencing is needed

nadya68 [22]

The field that is being fenced in has two 30 foot sides and 2 18 foot sides. The reason they are 18 is because there are 3 feet in a yard. You would then add all 4 sides together, equaling your perimeter.

The final answer is 96 sq feet.

A van and a truck both drove from Town A to Town B. The distance

Gala2k [10]

First we need to find out the time it took for the truck to reach town B.

$Speed= \frac{Distance}{Time}$

$40= \frac{200}{T}$
$T=5hours$

Now, because the van left 1.5 hours earlier and reached the destination 2.5 hours before, it took 1 hour less the the truck to arrive.

$5hours-1hour=4hours$ which is the time it took for the van to arrive.

Now we use the speed equation again to work out speed.

$Speed= \frac{200}{4}$

$Speed=50mph$ = speed of van

Hope this helped :)
