Answer: 75%.
Step-by-step explanation: 3/4 as a percentage is 75%.
100dl = 10 l, as the metric system is based on tens. So however many deciliters (dl) you have, divide it by ten and that's how many liters you have!
Answer:
The angular velocity is 8.38 radians per minute
Step-by-step explanation:
From the question,
It takes 45 seconds to complete a full revolution,
That is, 1rev/45secs
First, we will convert this to revolutions per minute (rev/min)
1rev/45secs =
= 4/3 rev/min
Now, we will convert this to radians per minute (rad/min)
1 revolutions = 2π rad
4/3 rev/min =
= 8.38 rad/min
Hence, the angular velocity is 8.38 radians per minute
, because the parabola has the maximum, not the minimum, (∩)
The Vertex form of a parabola equation:
V(-3;4), so:
*
The zeros and the conix form of a parabola equation:
, so:
*
We can also use the general form of a parabola:

Answer:
2nd option
Step-by-step explanation:
To convert from (x, y ) → (r, θ )
where
r =
θ = ( )
Here (x, y ) = (- 4, 5 ), a point in the 2nd quadrant
r = = =
θ = ( ) ≈ 51.3° ← related acute angle , then
θ = 180° - 51.3° = 128.7°
Thus
(- 4, 5 ) → (, 128.7° ) in polar form
