Answer:
–90° and 630°
Step-by-step explanation:
The described angle will be -90° plus any integer multiple of 360°. Possible values for the angle are ...
-90° and 630°
_____
Angles are conventionally measured counterclockwise from the positive x-axis. The angle shown in the attachment is measured clockwise, so represents a <em>negative</em> 90° angle.
Answer:
The differential equation is
dx/dt - Kx^4 = 0
Step-by-step explanation:
Let V represent the velocity of the particle moving along a straight line at time t.
We have the position to be x.
Then we have that
V is proportional to x^4
=> V = Kx^4
Where K is constant of proportionality.
Velocity is the derivative of the position vector with respect to time t, so we can write
V = dx/dt
And then
dx/dt = Kx^4
So that
dx/dt - Kx^4 = 0
This is the differential equation
