The question ask to find the rate of change of the distance from the paticle to the origin at this instant where as a particle is moving along the curve y = 5sqrt(5x+4) and base on my calculation, I came up with an answer of 254/sqrt(226). I hope you are satisfied with my answer and feel free to ask for more

Answer:

Step-by-step explanation:
The given function is
f(x) = 4x
As we know
f(x) = y, which implies x= 
Therefore,
y = 4x
x = 
as x= 
So,

replacing y by x in the above expression

So our inverse function is 
Answer:
B
Step-by-step explanation:
Fact: The diagonals of a parallelogram bisect each other. If NL= 15 the NP = 1/2 NL
1/2 NL = 15/2 = 7.5.
NP = 7.5
Answer: NP = 7.5 B
