Answer:

A. 10√7 kg wt

Step-by-step explanation:

The magnitude will be that of the long diagonal of a parallelogram that has sides 10 and 20. It must be more than 20, and cannot be 30 or more. That only leaves one answer choice:

10√7 kg wt

F(x)=2x^2+4x-16<br> g(x)=4x^2-16<br> Find (f/g)(x).

Nastasia [14]

Answer:

Step-by-step explanation:

$(\frac{f}{g} )(x) = \frac{2x^{2} +4x-16}{4x^{2} -16}$

2x²+4x -16 = 2(x²+2x-8); factor 2

= 2(x+4)(x-2) ;factor the quadratic equation

4x²-16 = 4(x²-4) ; factor 4

=4(x²- 2²) ; rewrite 4 as 2²

= 4(x-2)(x+2); now use the difference of two squares a²-b²=(a-b)(a+b)

so now we have:

$(\frac{f}{g}) (x) = \frac{2(x+4)(x-2)}{4(x-2)(x+2)}$ ; simplify (x-2) from numerator and denominator

and 2/4 as 1/2

$(\frac{f}{g}) (x) = \frac{(x+4)}{2(x+2)}$

An auto store is having a sale on motor oil. The chart shows the price per quart as the number of quarts purchased increases.

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.

Please have a look at the attached photo.

My answer:

Question 1: Please see the answer at the photo, remember that when number of quartz is = 1 , Price per quartz = 2. This will be merge against each other.

This step will be repeated for the remaining figure.

Question 2:

As an be seen from the scatter plot, price per quart decrease when the number of quarts increase so the relation between the two variable show a negative association

Hope it will find you well.
