Yes they are equivalent because when you multiply by 10, you move the decimal place one spot to the right.
Answer:
(-4, 2.5)
Step-by-step explanation:
-8/2=-4
5/2=2.5
Answer:
x = ± 2i
Step-by-step explanation:
note that 
= i
x² = - 12 ( take square root of both sides )
x = ± 
= ± 
= ± 2i
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. 3/5
Step-by-step explanation:
Count all the add numbers in 1-10 then add the 4 and you get
