Answer: g(-x) = 2x^2 +5x + 5
Step-by-step explanation:
This Is a topic under functions in mathematics, it deals with substituting "x" for the new entity that has been placed in the new function you're asked to look for.
Hence, to solve this, we simply substitute "-x" for "x" wherever "x" appears in the equation.
By doing so, we go straight to the given function.
2x^2 -5x + 5
And we go ahead with our substitution which goes thus:
2(-x^2) -5(-x) + 5
On simplifying, we then finally have have:
2x^2 +5x + 5.
This means:
g(-x) = 2x^2 +5x + 5
Answer:
No, because 379 times 17 6443
Step-by-step explanation:
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
Well on the left hand side collect the like terms
then see if it is equal to the right side..?
if it's not equal, there is no solution
Answer:
It is not accurate because only information from teenagers was used to make the claim.
Step-by-step explanation:
This is the correct answer because they only used the data that pertained to their teen readers. The magazine does not only have teen readers, but has many ages. The statement regarding internet use generalizes it to all readers, not just teens, therefore making its claim inaccurate because the scope of inference is not appropriate for the claim that was made.
