Second one
1/16
3/8 divided by 1/6=1/16
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:
748.23 in²
Step-by-step explanation:
<u>Area of a Regular Polygon</u>
where:
- n = number of sides
- l = length of one side
- a = apothem
Given:
- n = 6
- l = 101.8 ÷ 6
- a = 14.7
Substituting the given values into the formula and solving for A:
Therefore, the area of the hexagon is 748.23 in²
2x+4-x-3 = x +1
x + 1 = x + 1
0 = 0
your number has to be an infinite number of solutions. It can be any number.
