The graph is falling on the left hand side and rising on the right hand side.

Since the two ends of graph are in opposite direction, the exponent of variable has to be odd. For an even exponent of leading term, the two ends are in same direction.

Since the graph is falling on left and rising on right, this indicates that the coefficient of leading term is positive.

So, the leading term must have:
1) Odd exponent
2) Positive Coefficient

Thus, option Fourth is the correct answer

On a map, the scale shown is 1 inch: 20 miles. If a city is 900 square miles, what is the area of the city on the map?
WITCHER [35]

Answer:

2.25 square inches

Step-by-step explanation:

we know that

The scale is 1\ inch: 20\ miles

That means

1 inch on a map represent 20 miles in the city

so

An area of (1)(1)=1\ in^2 on a map represent an area of (20)(20)=400\ mi^2 in the city

Applying proportion

\frac{1}{400}\ \frac{in^2}{mi^2}=\frac{x}{900}\ \frac{in^2}{mi^2}\\\\x=900/400\\\\x=2.25\ in^2
