Answer:
22.4 hours
Step-by-step explanation:
The population of bacteria is modelled by the equation:

From the the question, the initial population of bacteria is 720.
So after 26 hours, we have:

This implies that:





We want to find how long it will take for there to be 1310 bacteria present.





To the nearest tenth , it will take 22.4 hours
Answer:
11) tan(7x+3) = OE/OJ
7x+3=arctan(OE/OJ)=45
x=6
12) a) x = 40
<ajq = <acq (base angles of isosceles triangle)
50+x+90=180
x=40
b) they are congruent triangle, reason HL (hypotenuse, leg)
aj=ac
aq=qa
right angle equal
Answer:A. provide evidence of a causal relationship between an independent variable and the variable to be forecast
Step-by-step explanation: Casual model tends to show the cause and effect relationship between the dependent variable to be forcasted and the independent variables upon which the dependent variable is dependent.
Casual model is frequently used in the field of Statistics and Economics when making forcasts about future investments or the cause of certain events,knowing what activities to carry out in the future.
