Not so sure.. but I got 9.6 meters below water level.
Answer:
Step-by-step explanation:
We start by subtracting from both sides of the second inequality:
Therefore, we conclude that:
Therefore, every point that satisfies the system has a -coordinate greater than .
Answer:
t=1/30 h = 2 min
Step-by-step explanation:
d = vt
system of equations:
d = 13t
d - 2/5 = t -> d = t+2/5
Solve
13t = t +2/5
t = 1/30 h = 60 min / 30 = 2 min
I think it is 1, 4, and 5
Answer:
The reference angle is
Step-by-step explanation:
The given angle is
The reference angle is the acute angle, that a given angle makes with the x-axis.
First let us make a sketch of the given angle. <em>See diagram in attachment.</em>
Let be the reference angle of
Then, from the diagram, we need to subtract from to get to .
We can therefore write the following equation and solve for .
We group like terms to get,
We collect LCM to get,
We simplify to get,
We divide through by
to get,
The correct answer is D.
