A culture is grown with a population of 45 million cells. The cell population is found to double every hour. What will the popul
Alexandra [31]
45 million * 2^{4} = 45million * 16 = 720million

Or you can use 
y=Ae^{kt}
A is equal to 45 million
To find the rate, k, we can plug in:
90million=45million*e^{k*1}

2=e^{k}
k=ln(2)
y=4.5*10^{7}*e^{t *ln2}
Knowing that t = 4
y = 4.5*10^{7}*e^{ln(2)*4}

y = 720 million

Ariel needs to paint the trim of a triangular box. If A (-2,4), B (2,2), and C (-1, -2) are the vertices of the triangle, what i
Kisachek [45]

Total length of the trim painted is 15.75 unit.

<u>Given:</u>

  • Co-ordinate of point A = (-2,4)
  • Co-ordinate of point B = (2,2)
  • Co-ordinate of point C = (-1,-2)

<u>Find:</u>

<em>Total length</em> of the trim painted

<u>Computation:</u>

Distance between two point = √(x1 - x2)² + (y1 - y2)²

Distance between AB = √(-2 - 2)² + (4 - 2)²

Distance between AB = √16 + 4

<em>Distance between AB</em> = 2√5 unit = 4.47 unit

Distance between BC = √(2 + 1)² + (2 + 2)²

Distance between BC = √9 + 16

<em>Distance between BC</em> = 5 unit

Distance between AC = √(-2 + 1)² + (4 + 2)²

Distance between AC = √1 + 36

<em>Distance between AC</em> = √37 unit = 6.08 unit

Total length of the trim painted = 4.47 + 5 + 6.08

Total length of the trim painted = <em>15.75 unit (Approx.)</em>
