On a word processing test, Iko typed 694 words in 15 minutes. On that same test six days later, Iko typed 753 words in 15 minute
Misha Larkins [42]

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

Please help quarter ends tomorrow and I don’t know what to do I’m failing all my classes
Nutka1998 [239]

Step-by-step explanation:

x = -10, y = 10

y= -4x+4

m1×m2 = -1

-4 × m2 = -1

m2 = 1/4

y-y1 = m(x-x1)

y-10 = 1/4(x+10)

y-10 = 1/4x +10/4

(×4)

4y-40=x+10

4y=x+50

x-4y+50=0

Write the equation in standard form. Identity the center and radius.<br> x² + y2 + 8x-4y-7=0
lorasvet [3.4K]

Answer:

equation;

(x + 4) {}^{2}  + (y - 2) {}^{2}  = 27

Center (-4,2)

Radius is

3 \sqrt{3}

Step-by-step explanation:

Since the x^2 and y^2 have the same coeffiecent this will be a circle in a form of

(x - h) {}^{2}  + (y - k)  {}^{2}  =  {r}^{2}

Where (h,k) is center

r is the radius

So first we group like Terms together

{x}^{2}  + 8x  +  {y}^{2}  - 4y - 7 = 0

Add 7 to both sides

{x}^{2}  + 8x +  {y}^{2}  - 4y = 7

( {x}^{2}  + 8x) +(  {y}^{2}  - 4y) = 7

Since the orginal form of the equation of the circle has a perfect square we need to complete the square for each problem

(\frac{8}{2} ) {}^{2}  = 16

and

( - \frac{4}{2} ) {}^{2}  = 4

so we have

{x}^{2}  + 8x + 16 +  {y}^{2}  - 4y + 4y = 7 + 16 + 4

{x}^{2}  + 8x + 16  +  {y}^{2}  - 4y + 4y = 27

(x + 4) {}^{2}  +  (y  - 2) {}^{2}  = 27

To find our center, h is -4 and k is 2

so the center is (-4,2)

The radius is

\sqrt{27}  = 3 \sqrt{3}

So the radius is 3 times sqr root of 3.
