A function f on [a, b] is called a step function if there exists a partition P = {a = u0 < u1 < ··· < cm = b} of [a, b]

such that f is constant on each interval (uj−1, uj ), say f(x) = cj for x in (uj−1, uj ). (a) Show that a step function f is integrable and evaluate " b a f.

Answer:

4(x^{2} -4)^{2} -76

Step-by-step explanation:

Take out 4:

4(x^2-8x)-12

=4(x^2-8x+16-16)-12

=4(x^2-8x+16)-64-12

=4(x^2-4)^2 - 76

=4(x^{2} -4)^{2} -76

If f(x)=2 sin 3x+C, then the maximum value of f(x) is:<br> 1)C<br> 2) C+2<br> 3) C+3<br> 4) C+6
Vladimir79 [104]
<h3>Answer:  C+2</h3>

Reason:

The largest sin(x) can get is 1, and the same goes for sin(3x).

Consequently, the largest 2sin(3x) can get is 2.

You can visually verify these claims by graphing each function with a tool like Desmos. Take note of the y coordinate of the highest points. See below.

Therefore, the largest f(x) = 2sin(3x)+C can get is 2+C or C+2

katie has red 32% of a book if she has to read 80 pages how many more pages does Katie have left to read
galben [10]
In this question, the information that Katie has already read 32% of a book that has a total of 80 pages is of great importance. This information is enough to find the required answer to the question.
Total number of pages Katie has to read = 80
Percentage of pages that Cathie read = 32%
Number of pages that Katie read = (32/100) * 80
                                                     = 256/10
                                                     = 25.6 pages
Then
The number of pages that Katie have left to read = 80 - 25.6
                                                                               = 54.4 pages
So Katie has 54.4 pages left to read.
