Answer:

x²-4x+7

-x²-6x-12

Step-by-step explanation:

1.) the first thing we do is expand the exponent (or mulitply (x-2)(x-2) the images below will show you how to do that

We get x²-4x+4 and then just need to add three

x²-4x+7

2.)

We do the same thing (expand the exponent) and get x²+6x+9

which means so far we have

-(x²+6x+9)-3

carry out the negative sign and subtract 3

-x²-6x-12

The midpoint formula is:
(point1 + point2)/2

1) (-2 + 12)/2 = 5

2) (-1 +5)/2 = 2
    (0+2)/2 = 1
     (2,1)

3) Sqrt of (x2-x1)^2 + (y2 - y1)^2
     sqrt of (7 -1)^2 + (-7 - 1)^2
     sqrt of (6)^2 + (-8)^2
     sqrt of 36 + 64
     sqrt of 100
     10

Hope this helps!

A bacteria culture contains 1200 bacteria initially and doubles every hour.(a) find a function n that models the number of bacte

labwork [276]

a) if the bacteria double every hour then it would 2^t(1200) where t is hours and 1200 is the amount in there to begin with. b) assuming the formula is correct it would be 2^24(1200). this becomes 20132659200 total in a day.

What is 14.3- 32.24=127.92 14.3p - 32.24 + 32.24 = 127.92 + 32.24 14.3p = 160.16 p=?

vladimir1956 [14]

Answer: p=11.2

Step-by-step explanation:

14.3p- 32.24 =127.92

14.3p - 32.24 + 32.24 = 127.92 + 32.24

14.3p = 160.16

p = 160.16 ÷ 14.3

p = 11.2

Hope this can help you :)
