Answer:

A

Step-by-step explanation:

The projection of vector B on unit vector a is

(B•a)a

av(unit vector of v)= 1/√2(-1,1)

u•av= 1/√2 × (-5+7)= √2

(u•av)av= √2 × 1/√2(-1,1)= (-1,1)

Answer:

g = 81.

Step-by-step explanation:

f = k/√g    where k is a constant

When f = 12 g = 36, so:

12 = k/√36 = k/6

k = 12*6 = 72.

So the relation is:

f = 72/√g

When f = 8:

8 = 72/√g

8√g = 72

√g = 72/8 = 9

g = 9^2 = 81.

20 POINTS!!!! FULL ANSWERS PLEASE Shannon is making a circle graph to show the type of weather for the past month. There are 12
viva [34]
Just to make it clear here is the graph. I was gone so long, it destroyed my answer.

Very briefly
8/30 * 360 = 96 which is the angle for the cloudy days.
12/30 * 360 = 144 which is the angle for the sunny days
10/30 * 360 = 120 which is the angle for the rainy days.

The graph shows how this would be plotted. It's not really well done, but it is there.
