Set an equation equal to 180° with angles A,B and C

140x-14+29-2x+9+x=180

Then combine like terms

39x+24=180

Subtract 24 from 180

39x=156

Divide by 39

x=4

Plug in 4 for x in the equations of angles A, B, and C

Answer:

see below

Step-by-step explanation:

= √(3 + 4i)

= 2 + i

ii.

= √(-8 + 6i)

= √2(-4 + 3i)

iii.

= √(-40 - 42i)

= √-2(20 + 21i)

iv.

= √i

= $\sqrt{\frac{2 + 3i}{5 - 4i} } +\sqrt{\frac{2-3i}{5+4i} }$

= $\sqrt{\frac{-2+23i}{41} } +\sqrt{\frac{2-3i}{46} }$

The number of bacteria present in a culture after t minutes is given as where k is a constant. if there are 8520 bacteria presen

andrew-mc [135]

Given that the situation has been modeled by the formula:
B=1000e^(kt)
given that B=8520 after t=15 min
then the value of k will be solved as follows:
plugging in the values in the formula and solving for k
8520=1000e^(15k)
8.52=e^(15k)
solving for k
15k=ln(8.52)
hence
k=ln(8.52)/15
k=0.1428
k=0.143
