Step-by-step explanation:
We are given:
This can be rewritten as
Next, we can bring the x's and y's to their respective sides by dividing by coty and x and then multiplying the dx to the other side. We can then change into . This gives us the differential
Now we can integrate each side
To integrate tan(y), we need to manipulate it
Now we can use u-substitution where
This gives us
Now, lets integrate both sides
Next, we can substitute our u value back in
Now we can add to the other side and subtract c from each side. This gives us
Next, we can apply a property of logarithms to combine this sum of two logs into one log.
Lastly, we can add a base e to each side to remove the ln
And here is our answer.
Answer:
The solution is (7, 6)
Step-by-step explanation:
You can find the solution of the system by multiplying the first equation by -3 and then adding together to get x to cancel.
-6x - 3y = -60
6x - 5y = 12
-----------------
-8y = -48
y = 6
Now that we have the y value, we can put it into either equation to find the x value.
2x + y = 20
2x + 6 = 20
2x = 14
x = 7
Therefore the point is (7, 6)
Answer:
It would be 2
Step-by-step explanation:
Because 2^2 = 4 -4 = 0
100%=8.50
1%=0.085
12%=1.02
112%=9.52
Answer=£9.52
