A bacteria population starts with 400 bacteria and grows at a rate of r(t) = (450.263)e1.12567t bacteria per hour. How many bact
dangina [55]

Answer:

11,713 bacteria

Step-by-step explanation:

Integrating the growth rate function gives us the population of bacteria at any given moment 't', in hours:

r(t) = (450.263)e^{1.12567t} \\\int\ {r(t)} \, dt =P(t) = \frac{450.263}{1.12567}*e^{1.12567t} +C

Since at t=0, P(t) = 400, the value of C is:

P(0) = \frac{450.263}{1.12567}*e^{1.12567*0} +C\\400 = 400*1+C\\C=0

The number of bacteria after 3 hours is:

P(3) = 400*e^{1.12567*3}\\P(3) =11,713

A motorcycle starts from rest . If its gain an acceleration of 2m/s^2 in 5 second , Calculate the final velocity.
densk [106]
  • initial velocity=u=0m/s
  • Acceleration=a=2m/s^2
  • Time=t=5s
  • Final velocity=v=?

Using first equation of kinematics

\\ \sf\longmapsto v=u+at

\\ \sf\longmapsto v=0+2(5)

\\ \sf\longmapsto v=10m/s

?????? I don’t get it
QveST [7]

Answer:

His gain was greater on the first play because if you convert 2 yards to feet you get 6ft and 6 feet is greater than 5 feet which means the football player had a greater gain on the first play.

Step-by-step explanation:

1 yard is 3 ft

2yards x 3=6 ft

6ft> 5ft

first play> Second play
