Answer:1) bacteria size = b(initial) * e^(r * t)
initial size = 300
final size = 1600.
Substituting the values into the main equation:
1600 = 300 * e^(r * 35 - 20)
solving for 'r'.
1600 = 300 * e^(r * 15)
1600/300 = e^(r * 15)
taking natural log on both sides to eliminate the power
ln(16/3) = ln[e^(r * 15)]
ln(16/3) = r * 15
r = ln(16/3) / 15
= 0.11159843
= 11.16%
To find the initial bacteria size,
Given: t = 20
300 = b * e^(0.1116 * 20)
Solving for b:
300 = b * e^2.232
b = 300/e^2.232
b = 32
Step-by-step explanation:
8 minutes has 8*60 or 480 seconds. If we divide 3000 meters by 480 seconds, we get an average speed of 6.25 m/s.
Answer is D.
Answer:
c = 121
Step-by-step explanation:
Given
t² - 22t
To complete the square
add ( half the coefficient of the t- term )² to t² - 22t
= t² + 2(- 11)t + (- 11)²
= t² - 22t + 121
with c = 121
Thus
t² - 22t + 121 = (t - 11)²
Answer:
x=4
Step-by-step explanation:
4x+1=17
4x=16
x=4
6x-3=21
6x=24
x=4
because GL and GT are congruent.
LO and OT are congruent.
