Answer:

Step-by-step explanation:

Given that there are two vectors U = (-8,0,1)

V = (1,3,-3)

To find projection of u on V and also projection of V on U

First let us find the dot product U and V

U.V = -8(1)+0(3)+1(-3)\\= -11

Projection of U on V =\frac{U.V}{|V|} \\=\frac{-11}{\sqrt{1+9+9} } \\=\frac{-11}{\sqrt{19} }

Similarly projection of V on U

=\frac{U.V}{|U|} \\=\frac{-11}{\sqrt{64+0+1} } \\=\frac{-11}{\sqrt{65} }

You are planning to purchase displays for your store which has 2400 sq ft of selling space. each display has a footprint of 10ft
polet [3.4K]
For this case, the sales space of the displays is given by:
 (2400) * (1-0.60) = 960 feet ^ 2
 We now look for the area of each display:
 (10) * (4) = 40 feet ^ 2
 With this information, we can then search the number of displays:
 N = (960) / (40)
 N = 24 displays
 Answer:
 
you can fit 24 displays.

If x=7cm what is the surface area of the geometric shape formed by this net
Mekhanik [1.2K]
There are four rectangles and 2 squares.

Let’s start with the four rectangles.
4 [ 2x(x)]
4 [ (2*7)(7)] = 392 cm^2
______________

Next, let’s find the SA for the two squares.
2 [(2x)^2]
** I need to be clear that both the 2 and the x in the parentheses are squared because the square, of course, is a “perfect square”. This was probably obvious and needless to say, haha oh well.
Next step: plug in values
2 [ [2(7)]^2 ] = 392 cm^2

TOTAL: 392+392 = 784 cm^2

Wow I should have realized the the 4 rectangles are the area as the two squares.

Good luck to you!

Find the value of x this question is for geometry please help

5x+15 = 6x-10

Subtract 5x from 6x which leaves you with 15 = x-10

Now you add 10 to both sides of the equal sign. 25 =          

x=25
