2 answers:
Answer:
Step-by-step explanation:
Solving For
Step 1: Multiplying 28.96 with 1 we get 2896
Step 2: add 0 and the multiply 28.96 with 4 we get 115840
Step 3: add 2 0's and the multiply 28.96 with 9 we get 2606400
Now adding all the three answer we get 2725136
Now decimal point of number and multiplier both are after 2 digit from units place so we will add decimal point 4 digit from unit place in final answer
hence we get 272.5136
Solving For
Step 1: Multiplying 63.7 with 5 we get 3185
Step 2: add 0 and the multiply 63.7 with 2 we get 12740
Now adding all the three answer we get 15925
Now decimal point of number and multiplier both are after 1 digit from units place so we will add decimal point 2 digit from unit place in final answer
hence we get 159.25

Answer:
We have the function:
f(x) = x^3 - 2*x^2
To sketch this, we need to graph some points, and then just draw a line that passes through the points.
The graph of this equation is shown below.
Now we can complete the question.
If the graph is below the x-axis in some interval, the function is negative in that interval
If the graph is above the x-axis in some interval, the function is positive in that interval.
If the graph goes up in a interval, then the function is increasing in that interval
If the graph goes down on an interval, then the function is decreasing in that interval.
Then:
1) f is------ on the intervals (−∞, 0) and (0, 2).
Here we can see that the graph is below the x-axis in those intervals, then here we have:
f is negative on the intervals (−∞, 0) and (0, 2).
2) f is------ on the interval (2,∞)
Here the answer is positive:
f is positive on the interval (2,∞)
3) fi is ------ on the interval (0, 4/3)
In the graph, you can see that the graph goes down in that interval, then the correct answer here is:
f is decreasing on the interval (0, 4/3)
4) f is------ on the intervals (−∞, 0) and (4/3, ∞).
In this case, we can see that the graph goes up in these intervals, then the correct answer here is:
f is increasing on the intervals (−∞, 0) and (4/3, ∞).
