Answer:
16
Step-by-step explanation:
2^4 is the same thing as 2*2*2*2*2. 2 times 2 is 4, times 2 is 8, times 2 again is 16.
Answer:

Step-by-step explanation:
The reference angle is the angle that the given angle makes with the x-axis.
For an ordered pair to share the same reference angle, the x and y coordinates must be the same or a factor of each other.
From the given options:

We observe that only the pair in option C has the same x and y coordinate with the second set of points being a negative factor of the first term. Therefore, they have the same reference angle.
V = (4cm)(5cm)(3cm) = 60 cm³
M = 120g
<u><em>Density = M/V = (120g)/(60cm³) = 2 g/cm³</em></u>
