Step-by-step explanation:
The doubling period of a bacterial population is 15 minutes.
At time t = 90 minutes, the bacterial population was 50000.
Round your answers to at least 1 decimal place.
:
We can use the formula:
A = Ao*2^(t/d); where:
A = amt after t time
Ao = initial amt (t=0)
t = time period in question
d = doubling time of substance
In our problem
d = 15 min
t = 90 min
A = 50000
What was the initial population at time t = 0
Ao * 2^(90/15) = 50000
Ao * 2^6 = 50000
We know 2^6 = 64
64(Ao) = 50000
Ao = 50000/64
Ao = 781.25 is the initial population
:
Find the size of the bacterial population after 4 hours
Change 4 hr to 240 min
A = 781.25 * 2^(240/15
A = 781.25 * 2^16
A= 781.25 * 65536
A = 51,199,218.75 after 4 hrs
To form the <u>converse</u> of the <u>conditional statement</u>, interchange the <u>hypothesis</u> and the <u>conclusion</u>.
Given conditional statement: "if two angles are both obtuse, the two angles are equal".
Here,
- hypotesis is: two angles are both obtuse,
- conclusion is: two angles are equal.
Then the converse statement will be: "If two angles are equal, then two angles are both obtuse".
Answer:
7.1
Step-by-step explanation:
If you count how many units are between the library and the park, it is seven units.
True, because the chord connect 2 points of the circumference, but radius connect the center and a point on the circumference.
