The ends of the graph go in different directions so this is an polynomial of the odd degree. As the domain values approach negative infinity, the range values approach infinity. As the domain values approach positive infinity, the range values approach negative infinity. This must be an odd degree polynomial with a negative leading coefficient. The answer is B. F(x) = -x^7 + 4x^3 - 2x^2

**Answer:**

**Step-by-step explanation:**

The formula is

A=future amount

P=present amount or princpal

r=rate in decimal

t=time in years

so

given

P=36000

r=4.75%=0.0475

t=6

use your calculator

A=47558.340

round to nearest cent

A=$47558.34

must pay back $47558.34

**Answer: The answers are **

**Step-by-step explanation: **Given in the question that Lana completed a 10-mile race in 90 minutes by running and walking both. She usually runs at a pace of 8.5 minutes per mile and walks at a pace of 12 minutes per mile. We need to find the number of minutes for which she ran and walk throughout the race.

Let, Lana runs for 'x' miles and walks for 'y' miles. Then, we have

Multiplying the first equation by 8.5 and subtracting from the second equation, we have

Therefore,

Thus, time for which Lana ran is

And, the time for which Lana walks is

**Thus, the answers are**
