The dot product of two vectors is defined as the sum of the multiplication of each of its components.
We have then:
B = [2 8 .6 3]
A = [3 0 2 -1]
Making the product point:
BA = [2 8 .6 3] [3 0 2 -1]
BA = (2 * 3) + (8 * 0) + (0.6 * 2) + (3 * (- 1))
BA = 4.2
Answer
BA = 4.2

Annette [7]

Answer:

$\frac{1}{4,650}\ astronomical\ unit$

or

$2.15*10^{-4}\ astronomical\ unit$

Step-by-step explanation:

we know that

One astronomical unit is about 93,000,000 miles

so

using proportion

Find out how many astronomical unit represent 20,000 miles

Let

x ----> the number of astronomical unit

$\frac{1}{93,000,000} =\frac{x}{20,000}\\\\x=\frac{20,000}{93,000,000}\ astronomical\ unit$

simplify

$\frac{1}{4,650}\ astronomical\ unit$

or

$2.15*10^{-4}\ astronomical\ unit$

w = amount she earns for her work.

twice that is 2*w, or 2w.

6 more than that is 2w + 6.

$\bf 21~~\stackrel{is}{=}~~\stackrel{\textit{twice her earnings + 6}}{2w +6}\implies 15=2w\implies \cfrac{15}{2}=w\implies 7\frac{1}{2}=w$
