Answer:
22
Step-by-step explanation:
5t=99+11
5t=110
divide both side by 5 to find the value of t
Answer:
-2
Step-by-step explanation:
the slope is 4/-2
so when you reduce it you get -2
Answer:
The balance is $256
Step-by-step explanation:
Given
Required
Determine the balance after 20 visits
Represent the balance with b
Represent the visitation with v
The relationship between the given parameters is:
This gives:
Make b the subject
To get the actual balance after 20 visitation;
Substitute 20 for v
Hence:
<em>The balance is $256</em>
Answer:
4
Step-by-step explanation:
It's a little hard to explain but add the minutes first and it adds up to 60 minutes, making the time now 5. Then if you think it through, 12 hours from 5 is 5 again so 11 hours from 5 would be one less so the answer is 4.
Step-by-step explanation:
x*(dy/dx) +y = x*(dy/dx) +1*y=x*(dx/dy)+dx/dx*y = (d(xy) /dx)
d(xy) /dx = x^ex<->
d(xy) =xe^x*dx
We integrate both parts with their respective variables.
Integral of d(xy) is xy+c.
Integral of xe^x*dx is equal to xe^x - e^x+c.
We have to integrate by parts:
Integral(x*e^x) = x*e^x - integral((x) 'e^x) = x*e^x - integral(e^x)= x*e^x-e^x.
We have that xy + c = x*e^x - e^x + c1, where c and c1 are non defined real constants.
So we get that xy= x*e^x - e^x + c2, where c2 is a real constant.
