Answer:
v=206ft/s , a=120ft/s
Step-by-step explanation:
We are given the equation of displacement
upon differentiating the given equation
ds/dt = 
upon substituting t = 3
v = 206ft/s
a= dv/dt
upon differentiating
dv/dt = 36t + 12
put t= 3
a=120ft/s
Answer:
8 miles
Step-by-step explanation:
Given: A runner can run 5 miles in 26 minutes, 41.6 minutes = ___
To find: At this rate, how many miles can he run and 41.6 minutes?
Solution: If the runner ran 5 miles in 26 minutes, to find how far he ran in 41.6 minutes, set up a fraction:
let x be the variable

Apply fraction cross multiply;


Divide both sides by 26

Simplify

Then, at the rate, the runner ran 8 miles 41.6 minutes
Step-by-step explanation:
4x + y = 6 => 8x + 2y = 12.
8x + 2y = 12
+ (-5x - 2y = -3)
=> 3x = 9, x = 3.
Therefore 4(3) + y = 6, 12 + y = 6, y = -6.
The solutions are x = 3 and y = -6.
If the credit card Balance is of, lets say, $2000 and if the interest rate is 2.7% and then he has a minimum payment of 2% which in terms of money will be $40 then it will take 9 years and 9 months to payoff his balance and the total interest wil be of $2640.45. If the credit card balance is not $2000 then you can take the amount they give you and do a cross multplication.
It would be the third one !!!!!!!!!
