1. The answer is 16^2, so B.
16 x 16 = 256
2. The answer is 17, so B.
Some of the factor of 68 are: 1, 2, 4, 17, 34 and 68.
3. The answer is 15, so B.
Only 15 is composite since it contains more than a factor, which are 3 and 5. The rest of the numbers are prime since they only contain a factor.
4. The answer is 2^2^3^7, so B.
The factor tree:
84
2 x 42
2 x 2 x 21
2 x 2 x 3 x 7
Hope this helps! :)
Answer:
the formula is 1.5x^2
Step-by-step explanation:
Since the vertex is 0,0 h and k are both 0
then you plug in the -6 and -9 to the equation
a(-6)=-9
3/2(x)^2
hope that answers your question
Answer:

Step-by-step explanation:
So we have the indefinite integral:

This is the same thing as:

So, let's do integration by parts.
Let u be (ln(x))². And let dv be (1)dx. Therefore:

Simplify:

And:

Therefore:

The x cancel:

Move the 2 to the front:

(I'm not exactly sure how you got what you got. Perhaps you differentiated incorrectly?)
Now, let's use integrations by parts again for the integral. Similarly, let's put a 1 in front:

Let u be ln(x) and let dv be (1)dx. Thus:

And:

So:

Simplify the integral:

Evaluate:

Now, we just have to simplify :)
Distribute the -2:

And if preferred, we can factor out a x:

And, of course, don't forget about the constant of integration!

And we are done :)
