Answer:
a) The continuous rate of growth of this bacterium population is 45%
b) Initial population of culture at t = 0 is 950 bacteria
c) number of bacterial culture contain at t = 5 is 9013 bacteria
Step-by-step explanation:
The number of bacteria in a culture is given by
n(t) = 950
a) rate of growth is
Bacteria growth model N(t) = no
Where r is the growth rate
hence r = 0.45
= 45%
b) Initial population of culture at t = 0
n(0) = 950
= 950
= 950 bacteria
c) number of bacterial culture contain at t = 5
n(5) = 950
= 950
= 9013.35
= 9013 bacteria
So discriminant is being counted from that equation:
b^2-4ac = 36-36 = 0
As discriminant is 0, then there is just 1 root -> -b/2a = 6/2 = 3.
Answer: <em>In the upper triangle x = 33° and in the lower triangle x = 128°</em>
Step-by-step explanation:
<em><u>Upper triangle:
</u></em>
<em>x = (180° - 114°) ÷ 2 = 33°</em>
<em><u>Lower triangle:</u></em>
<em>x = 180° - 26° × 2 = 128°</em>
