Step-by-step explanation:
The 11th term means there are 10 gaps in between the first term and the 11th term. Each gap has a difference of +4, so the 11th term would be given by 10 * 4 + 1 = 41.
Answer:
The domain is all real numbers.
The function is always decreasing
Step-by-step explanation:
Assuming the given function is

for

Then f(x) is an exponential decay function.
This means that, the domain will be all real numbers.
The range will be y<0
The y-intercept is (0,-1)
There is no x-intercept.
The graph is a decreasing function.
Answer:
s ≥ 170
Step-by-step explanation:
The problem raises the following statement: "The cruising speed of the bullet train will be at least 170 miles per hour"
Which means that the train has a speed of 170 miles for now or higher, knowing this we can pose the inequality.
Knowing that "s" is the train's cruising speed (in miles per hour), we have to:
s ≥ 170
This would be the inequality that the statement represents.
