saul85 [17]

Answer:

Rate of change per hour in the number of bacteria is r=0.28

Step-by-step explanation:

Given : There are 16 bacteria in a beaker and four hours later there are 228 bacteria in the beaker.  

To find : What is the rate of change per hour in the number of bacteria.

Solution :

At initial number of bacteria is 16

After 4 hours number of bacteria is 228

Rate of change per hour is given by

A=Pe^{rt}

where A = total number of bacteria, P = initial number of bacteria, r= rate of change , t= time  

228=16(e^{4r})

14.25=(e^{4r})

Taking log both side,

log(14.25)=4r

1.15=4r

0.28=r

Therefore, Rate of change per hour in the number of bacteria is r=0.28

cupoosta [38]

  4y⁴ - 8y³ - (5y³ + 6y + 3y⁴)

= 4y⁴ - 8y³ - 5y³ - 6y - 3y⁴

= (4y⁴  - 3y⁴) + (- 8y³ - 5y³) - 6y

= y⁴ - 13y³ - 6y

Answer:  y⁴ - 13y³ - 6y
