The "dot product" of two vectors has several different formulas.
Since you are given the x- and y-coordinates of both vectors a and b, we can apply the formula
a dot b = ax*bx + ay*by, where ax=x-component of vector a, by=y comp of vector b, and so on.
So, for the problem at hand, ax * bx + ay * by becomes
3(-2) + (-8)(-6) = -6 + 48 = 42 (answer). Note that the dot product (or "scalar product" is itself a scalar.

Answer:
A. The data are continuous because the data can take on any value in an interval.
Step-by-step explanation:
A continuous data is any data set having infinitely many possible values and those values cannot be counted, meaning they are uncountable. Any quantity such as height, volume, weight, density, length, pressure, temperature, speed, distance, time are generally a continuous data.
Hence, the exact heights of different elephants represents a continuous data because the data can take on any value in an interval.
On the other hand, a discrete data is any data set in which the number of possible values are either finite or countable. Thus, a discrete data can only take on specific values. For example, the value of a fair die, number of sweets in a jar, number of eggs in a crate etc.
Just plug the corresponding x value on the left of a,b,c, and d into the equation. If you don't understand the equation, it is asking you to multiply x by 3 and then subtract 2.
These are the answers:
-11, -5, 1, 4.
Good luck!
