Using the slope formula:
Answer:
I think if it takes me 8 hours then it will surely take him 8 hours
The height of the jet in miles is 10 miles. There are 5280 feet in a mile, so you would divide 52800 by 5280 and get 10 miles.
Answer:
The answer is
<h2>
</h2>
Step-by-step explanation:
To find the inverse of f(x) , equate f(x) to y
That's
y = f(x)
We have
Next interchange the terms that's x becomes y and y becomes x
<u>Next solve for y</u>
Move 3 to the other side of the equation
That's
<u>Divide both sides by 25</u>
We have the final answer as
Hope this helps you
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
