Integrate term by term and then plug in bounds
6.7
Answer:

Step-by-step explanation:
For this case we need a line parallel to the plane x z and yz. And by definition of parallel we see that the intersection between the xz and yz plane is the z axis. And we can take the following unitary vector to construct the parametric equations:

Or any factor of u but for simplicity let's take the unitary vector.
Then the parametric equations are given by:



Where the point given 
And then since we have everything we can replace like this:




There are two (2) terms, "2x" and "8", making it a "binomial" (the "bi" prefix meaning "two"). The only variable is x, and its power is 1, making the "2x" term a first-degree term. Since the highest degree of any term is 1, the polynomial is first degree.
Selection A is appropriate.
The first one. 1 machine= x 5 mach.=5x. Total time is thus 5x+2/3=1 3/4h. Simply find x by doing 105min-40min/5 and that is 13.
Answer: 19/4
Explanation: To write a mixed number as an improper fraction, first multiply the denominator times the whole number and then add the numerator.
So here, we multiply the denominator which is 2 times the whole number, 3, and then we add the numerator. So we have (4 x 4) + 3 which simplifies to 19.
Finally, we put our new number over our old denominator and we have our answer which is 19/4.
So 4 and 3/4 can be rewritten as the improper fraction 19/4.
