For example, in the composition of(f g)(x) = f(g(x)), we need to replace each x found in f(x), the outside function, with g(x), the inside function. Step 3: Simplify the answer. Examples – Now let's use the steps shown above to work through some examples. Example 1: If f(x) = –4x + 9 and g(x) = 2x – 7, find(f g)(x).
It is 160 ! I hope I could help
Answer:
1.8 minutes or 108 seconds
Step-by-step explanation:
The question tells us that the larger belt moves 300 lbs in 2 mins. And this is equal to 150 lb per minute
The question also tells us that a smaller belt moves the same quantity of 300 lbs in 18 mins. And this is equal to an average of 16.667 lb per min.
Both belts will move at a rate of 166.667 lb per min.
So it will take them 300 / 166.667 = 1.8 min or 108 s.
Therefore, the answer is 1.8 min
Answer:
So the decay percentage rate is of 70.8%
Step-by-step explanation:
An exponentil function has the following format:
In which c is a constant.
If a>1, we have that a = 1 + r and r is the growth rate.
If a<1, we have that a = 1 - r and r is the decay rate.
In this problem:
a = 0.292
A is lesser than 1, so r is the decay rate.
1 - r = 0.292
r = 1 - 0.292
r = 0.708
So the decay percentage rate is of 70.8%
Answer:
Step-by-step explanation:
Given is the piecewise function.
The first part is increasing function y = x + 6, when x ≤ -3
The second part is decreasing function y = -x when x > -3
The above is reflection in the first graph (top one)
