The velocity is the derivative of position.
... v(t) = r'(t) = -5sin(t)i +4cos(t)j . . . . velocity
The acceleration is the derivative of velocity.
... a(t) = v'(t) = -5cos(t)i -4sin(t)j . . . . acceleration
The speed is the magnitude of velocity.
... s(t) = ||v(t|| = √((-5sin(t))² +(4cos(t))²)
... = √(25sin(t)² +16(1 -sin(t)²))
... s(t) = √(16 +9sin(t)²) . . . . speed
_____
Of course, derivatives of these functions are found from ...
... (d/dt)(sin(t)) = cos(t); (d/dt)(cos(t)) = -sin(t); (d/dt)(a + b) = da/dt + db/dt.
Actually I can help you in three of them as the number "3" is not confined between the arrays ND and NE
So:
It would be
angle END
or
angle DNE
or
angle N
Answer: HOPE THIS HELPS YOU! :D
For 13 it’s 1
Step-by-step explanation:
Because the dot on one is the farthest from the rest of the dots.
if the $1 is 75%, then there are 300 of the one dollar prizes
if the $5 is 15%, then there are 60 of the five dollar prizes
so 300 $1 prizes And 60 $5 prizes
360 prizes are either worth $1 or $5
Alrighty, so, If I remember correctly: I believe the answer you're looking for is 5.76 x 10^3
Imagine there's a decimal after the zero. You can only have one integer in FRONT of the decimal therefore you move your decimal 3 places to the left. This gives you 5.76 x 10^3 because you always remove the zero when it's at the end of the number.
Hope this helps!
