Answer:
It goes to zero three times
Step-by-step explanation:
s(t) = e^ cos(x)
To find the velocity, we have to take the derivative of the position
ds/dt = -sin x e^ cos x dx/dt
Now we need to find when this is equal to 0
0 = -sin x e^ cos x
Using the zero product property
-sin x=0 e^cos x= 0
sin x = 0
Taking the arcsin of each side
arcsin sinx= arcsin 0
x = 0 ,pi, 2 pi
e^cos x= 0
Never goes to zero
Use A: to find the value of x. In order to find that you would have to match one part of the proportion. x should be the numerator over 15 and 12 should be over 20 (The total length of that side of the triangle). Good luck. : )
Answer:
The side lengths remain the same, and the position of the figure changes.
Step-by-step explanation:
A translation is a slide of a figure. A figure can be slid vertically, horizontally or diagonally.
Think of sliding a game board across a table. The lengths of the sides of the board do not change; the angles formed by the sides of the board do not change; and the way the board is turned does not change. This means the only correct option would be the last one.
Answer:
C 9i
D -9i
Step-by-step explanation:
sqrt(-81)
sqrt(81) sqrt(-1)
we know that sqrt(-1) = i
±9i
