Answer:
18 and 19
Step-by-step explanation:
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:
-8
Step-by-step explanation:
-8m⁴ n⁴
m = 0.5 = 1/2
n = 2
Substitute
-8 * (1/2)⁴ * (2)⁴
-8 * (1/16) * (16)
-8
Answer:
6
Step-by-step explanation:
The absolute value of a non-negative number is the same number.
Example: The absolute value of 4 is 4.
If a number is negative, its absolute value is the same number, without the negative sign.
Example: The absolute value of -3 is 3.
