Answer:

1/2 ornament in an hour

Step-by-step explanation:

Given

Orna\ ments = 2

Time = 4

Required

Determine the ornaments per hour

This question implies that we calculate the unit rate.

Unit\ Rate = \frac{Orna\ ments}{Time}

Substitute values for Time and number of ornaments

Unit\ Rate = \frac{2}{4}

Unit\ Rate = \frac{1}{2}

<em>This implies that Constance can decorate 1/2 ornaments in an hour</em>

Please show your work<br> What is the solution of the equation <img src="https://tex.z-dn.net/?f=%20%5Csqrt%7B2x%2B13%7D%20-5%3D
Hatshy [7]
Add the five to each side.
then square it to get rid of the square root
2x+13=(5+x)^2
2x+13=x^2+10x+25
2x=x^2+10x+12
x^2+8x+12=0
(x+6)(x+2)
x+6=0
x+2=0
answers are -2 and -6, however, when pluging -6 in it doesnt work, so it is only -2.

If u is a unit vector, find u · v and u · w. (assume v and w are also unit vectors.) equilateral triangle
serg [7]

solution:

we know that ,

u.v = ΙuΙ ΙvΙcosθ

here,

θ =60° (since the given triangle is equilateral triangle)

u.v = ΙuΙ ΙvΙcos60°

     = 1 x 1 x 1/2

u.v = 1/2

now, u.w = ΙuΙ ΙwΙcosθ

              = ΙuΙ x cos(60x2)

u.w = -1/2
