Answer:
Step-by-step explanation:
An odd function <em>f</em> is one where . We can interpret this is meaning: reflecting the graph horizontally
has the same effect as reflecting it vertically
. The only graphs that meet this requirement are ones with reflectional symmetry across the line y = x, so we can immediately elimate the functions
and
, which have horizontal symmetry, but not the kind of symmetry we're looking for.
That leaves us with and
. One feature of exponents we can utilize is that -1 to an even power is 1, while -1 to an odd power is -1. If we want
, we need to flip the signs of <em>all </em>the coefficients, and we can only do that if all the powers of x are odd. The only function with only odd powers of x is
, and plugging in -x to the function reveals that
So the only odd function on the list!
Answer:
0.43 ft/hr
Step-by-step explanation:
dv/dt = 15ft³/hr
Height = 10ft
We are required to get dh/dt
h = 3r
r = h/3
Formula for volume = 1/3πr²h
We put value of h
1/3π(h/3)²h
= 1/3π(h²/9)h
= 1/3πh³/9
= πh³/29
dv/dt = 1/27π.3h²dh/dt
= dv/dt = πh²/9dh/dt
Remember dv/dt = 15
When we put this in we get
dh/dt = 15x9/3.142x10²
= 135/314.2
= 0.43 ft³/hr
