Answer:
Step-by-step explanation:
P(E)=3/6=1/2
So it is equally probable to roll even as it is to roll an odd.

The equation is derived from the conservation of energy, specifically from potential energy stored at a given height in a gravitational field.
When potential energy is completely converted to kinetic energy you have:
(mv^2)/2=mgh divide both sides by the mass m
v^2/2=gh multiply both sides by 2
v^2=2gh take the square root of both sides
v=√(2gh) and working with imperial units for acceleration due to gravity, g=-32ft/s^2
v=√(-64h) but the change of h as it falls is negative h so
v=-√(64h) so if an object falls from a height of 88ft we have:
v=-√(64*84)
v=-√5376
v≈-73.32 ft/sec (to the nearest hundredth of a foot per second)
Note that this is the velocity, it is negative 73.32 ft/sec.
The question inadvertently asked for velocity and provided answers for SPEED. Velocity is a vector and has both magnitude and direction, whereas speed just has magnitude.
So its final speed is 73.32 ft/sec
So if they actually wanted velocity none of their answers is correct :P
Answer:
1/5
Step-by-step explanation:
2/5 - 1/5
2-1 = 1
5 Stays the same so your answer is 1/5
Po ^2 = 6^2 + 8^2
Po^2 = 36 + 64 = 100
So Po = 10
Sin x = 8/po = 8/10= 0.8
Cos y = 6/po = 6/10=0.6
Answer:
Step-by-step explanation:
Since the triangle has a right angle, we are going to use pythaogoran theoem, which is 
, where a and b are the legs and and c is the hypotunese/ slated side. Let set it up.
9+36=c^2
45=c^2
=
Then we are going to find a perfect squarre root(1,4,9,16,25....) to simplify the radical
The perfect square root is 9 because 9 goes into 45 5 times.
Then take the sqr root of 9 and we have
