Answer:
Step-by-step explanation:
Look at the component form of each vector.
Note that vector c is <4,4> and vector d is <-2,-2>
If one imagined the line that contained each vector, the line for both would have a slope of 1, because 
Since they have the same slope they are parallel, but since they are in opposite directions, we often call them "anti-parallel" (simply meaning parallel, but in opposite directions).
If two vectors are parallel, one vector can be multiplied by a scalar to result in the other vector. This means that there is some number "k", such that 
, or equivalently, 
and 
.
If and , we just need to substitute known values and solve for k:
Double checking that k works for the y-coordinates as well:
? 
So, 
<span>Absolute value describes the distance of a number on the number line from 0 without considering which direction from zero the number lies. the absolute value of a number is negative.</span>

well the true answer is 12.56, i might of rounded wrong lol
Answer:
d) The data are quantitative because they consist of counts or measurements.
Step-by-step explanation:
The number of cases of flu treated at a certain hospital in different years consists in integer numbers (there cannot be 108.4 cases of flu treated in one year, just 107, 108, 109, etc).
Therefore the date are quantitative because the data consists of numbers which are counts of a certain number of individuals who were affected by the flu during different years.
