Answer:

The improve in speed is 3.9334 words/min

Step-by-step explanation:

we will find speed at both occasions  and then we can subtract them

First test:

total number of word =694

total time =15 min

we know that

speed = (total number of words)/( total time)

now, we can plug values

speed is

=\frac{694}{15} word/min

s_1=46.2666 word/min

Second test:

total number of word =753

total time =15 min

we know that

speed = (total number of words)/( total time)

now, we can plug values

speed is

=\frac{753}{15} word/min

s_2=50.2 word/min

So, improve in speed is

=s_2-s_1

=50.2-46.2666

=3.9334 word/min

RSTU is a rectangle with vertices at R(-3,1), S(1 ,1), T(-3,3) and U (1, 3). Describe two lines of reflection that would carry t
miss Akunina [59]

Answer:

The two lines of reflection are x=-1 and y=2

Step-by-step explanation:

I will attach a file with the graph of the rectangle and the lines of reflection.

We know that RSTU is a rectangle with vertices at R=(-3,1) , S=(1,1),

T=(-3,3) and U=(1,3)

The first step is to draw the vertices on the plane and them the rectangle.

The rectangle is a symmetrical figure. Therefore if we want to carry the rectangle onto itself using a line of reflection this line must goes through the centroid of the rectangle.

Given that we have a rectangle whose width is a and its length is b its centroid will be place at (\frac{a}{2},\frac{b}{2}).

Looking at the graph and using this information we find that the two lines of reflection are x=-1 and y=2.
