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.
It should be around 24.56 i rounded tho
Answer: b commutative property
Step-by-step explanation: idid the test and i got it right
The answer is y=bx-b(a-1), because when x=a then y=b.
Answer:
5:6
Step-by-step explanation:
To find the ratio of side lengths you need to cube root of the ratio of the volumes. The reason you use the cube root is because you are multiplying 3 things together when you find volume.
![\sqrt[3]{\frac{125}{216} } =\frac{5}{6}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B%5Cfrac%7B125%7D%7B216%7D%20%7D%20%3D%5Cfrac%7B5%7D%7B6%7D)
5 : 6
