Answer:

Step-by-step explanation:

w = 45+ 6d

A/Q

w=100

45+6d=100

6d=100-45

6d=55

d=55/6

d=9.16666

d=9 (appx)

.: after 9 days the chick would be of 100 grams.

Help ASAP! you help me I can help you
const2013 [10]

Use the distance formula <em>or Pythagorean Theorem</em> to find the length of each of the sides.

<u>(-5, -4) to (2, 6)</u>

d = \sqrt{(-5 - 2)^{2} + (-4 - 6)^{2} }

  = \sqrt{(- 7)^{2} + (-10)^{2} }

  = \sqrt{49 + 100}

  =  \sqrt{149}

<u>(2, 6) to (4, -4)</u>

d = \sqrt{(2 - 4)^{2} + (6 - (-4))^{2} }

  = \sqrt{(- 2)^{2} + (10)^{2} }

  = \sqrt{4 + 100}

  =  \sqrt{104}

  = 2\sqrt{26}

<u>(-5, -4) to (4, -4)</u>

you can just count the distance between the coordinates: d = 9

<u>Perimeter</u> = (-5, -4) to (2, 6) + (2, 6) to (4, -4) + (-5, -4) to (4, -4)

                =       \sqrt{149}          +    2\sqrt{26}           +             9

Answer: \sqrt{149} + \sqrt{149}  + 9
