Answer:
The answer is "10.25"
Step-by-step explanation:
Please find the graph in the attachment:
In the given kite diagram the PT= TR so,
in 
we applying the Pythagoras theory:
Cube surface area = side^2 * 6
cube surface area = 2.3^2 * 6
cube surface area = 31.74 cm^2
Don't know whether or not you've encountered differential equations yet, but will try that approach here.
The growth rate is dy/dt = ky (which states that the rate is proportional to the size of the population, y, and k is a constant.
Grouping like terms,
dy
--- = kt, so y = Ne^kt
y
We are told that at t=0, there are 880 bacteria. Thus, 880=N. Therefore,
y = 880e^(kt). After 5 hours the pop will be 4400; using this info, find k:
4400=880e^(5k), or 5 = e^(5k). So, our y = 880e^(kt) becomes
y = 880e^(5t).
What will be the pop after 2 hours? y(2)=880e^(10) = 880(22026) =
approx. 19,383,290 bacteria
Time to reach a pop of 2550? 2550 = 880e^(5t). Find t.
ln 2550 = ln 880 + 5t, so ln 2550 - ln 880 = 5t. Divide both sides by 5 to obtain this time, t.
Answer: Cara takes longer to get to the library. She used 3 minutes more
Step-by-step explanation:
Cara leaves her house at 10:03 and arrives at the library at 10:17. The number of minutes used by Cara will be:
= 10.17 - 10.03
= 14 minutes
Irena leaves her house at 11:55 and arrives at the library at 12:06. The number of minutes used by Irena will be:
= 12.06 - 11.55
= 11 minutes
Cara takes longer to get to the library. She used (14 - 11) = 3 minutes more
Answer:
11
Step-by-step explanation:
the greatest common factor is 8 so you know you have to have 8 rows, divide all of those number by 8 and add the answers
