Answer:
A
Step-by-step explanation:
The position of an atom moving inside a cathode ray tube is given by the function:
Where f(t) is in meters and <em>t</em> is in seconds.
And we want to determine its instantaneous velocity at <em>t</em> = 2.5 seconds.
The velocity function is the derivative of the position function. Thus, find the derivative of the function:
<em /><em />
<em />
Then the instantaneous velocity at <em>t</em> = 2.5 will be:
Our answer is A.
Answer:
Therefore the value of bond will triple after 17.72 years.
Step-by-step explanation:
The formula of Compounded continuously
A= Amount after t year
P= initial amount
r = rate of interest
t= time in year.
Given that,
Jacobs college saving are invested in bond that pay 6.2% compounded continuously.
Let after t years the initial amount P will be triple i.e 3P.
Here P=P, A=3P, r= 6.2%=0.062
[ Multiply
both sides]
Taking ln both sides
[ since
]
years
Therefore the value of bond will triple after 17.72 years.
