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.
The inequality symbol in the picture stands for greater than or equal to, so 9, 11, 12 all apply in the equation
Answer:
9 × 2^(13)
Step-by-step explanation:
hello :
the nth term is : An =A1 × r^(n-1)
a common ratio is : r and A1 the first term
in this exercice : r= -3-(-7)36/18 = 18/9 =2 A1 = 9
when : n =14 you have the 14rd term A14
A14 = 9 × 2^(14-1) = 9 × 2^(13)
Im doing it right now and my best choice is going to have to be D Sorry if im wrong but i noticed that no one answered and i decided to give a shot again im sorry if it's wrong. Have a nice day! :3
