Answer:
a=1
Step-by-step explanation:
Because x-1 is factor of f(x)
for x1=1, f(1)=0, then
f(1)=5*1^3+a*1^2-4*1-2=0
5*1+a*1-4-2=0
5+a-6=0
a-1=0
a=1
If x is 0 y is -5
if x is 2 y is 0
if x is 4 y is 5
hope that helps

Answer:
<u>The correct answer is B. 40 mph</u>
Step-by-step explanation:
1. Let's review the information provided to us to answer the question correctly:
Distance (d) the car traveled = 120 miles
Time (t) of the travel = 3 hours
2. What is the average rate of speed?
Rate of speed (r) = Distance (d) the car traveled/Time (t) of the travel
Replacing with the real values, we have:
Rate of speed (r) = 120/3 miles per hour
Rate of speed (r) = 40 miles per hour
<u>The correct answer is B. 40 mph</u>
