Step-by-step explanation. Better do ur I ready test stop cheating
To solve this problem you must apply the proccedure shown below:
1. You have the following parametric equations given in the problem above:
<span> x=e^3t
y=e^-t</span>
2. Therefore, you must solve fot et in the second equation, as below:
y=e^-t
y=1/e^t
e^t=1/y
3.Substitute into the first equation:
x=e^3t
x=(e^t)^3
x=(1/y)^3
x=1/y^3 (y>0)
The answer is: x=1/y^3 (y>0)
Answer: 5
Step-by-step explanation: I got it right
Answer:
n = 3 + i√11 , 3 - i√11
Step-by-step explanation:
This is a quadratic equation and the first step is to write it in standard form:
5n^2 - 30n + 100 = 0
Divide through by 5:
n^2 - 6n + 20 = 0
Completing the square:-
(n - 3)^2 - 9 + 20 = 0
(n - 3)^2 = -11
n - 3 = i√11 or - i√11
n = 3 + i√11 , 3 - i√11
(2 complex roots).
