Answer:
On a coordinate plane, a curved line crosses the x-axis at (negative 4, 0), (0, 0), and (4, 0).
Step-by-step explanation:
An odd function is symmetric about the origin. It satisfies the requirement that ...
f(-x) = -f(x)
The appropriate choice is the curve that goes through points (-4, 0), (0, 0) and (4, 0).
By using cross mutliplication, there are 24 gallons in the water tank after 30 minutes.
<h3>How to estimate the filling time of a water tank by cross multiplication</h3>
According to the statement the water tank is full at constant rate, 10 % tank capacity per each 5 minutes. The tank has a capacity of 40 gallons. The gained capacity is determined by the following cross multiplication, where the water capacity is directly proportional to filling time:
x ∝ t
x = (n / 100) · V × (T / t) (1)
Where:
- n - Initial capacity percentage of the water tank, in percentage.
- V - Full capacity of the water tank, in gallons.
- T - Final time, in minutes.
- t - Initial time, in minutes.
x = [0.1 · (40 gal)] × (30 min / 5 min)
x = 24 gal
There are 24 gallons in the water tank after 30 minutes.

Answer:
A is wrong
Step-by-step explanation:
Okay so because we are talking about the rate of km per hour. This means that car A is going 208km per hour. We are trying to find out how many km at 12 hours so we are going to multiply:
208x12= 2496km
Now we have to do the same for car B:
215x12= 2580km
Next we have to figure out how many km more did car B drive than car A so we have to subtract:
2580-2496= 84km
Hope this helps(;
