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
Could i see a picture please
If the equation of a line is written in the
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
form,
![b](https://tex.z-dn.net/?f=b)
is the y-intercept.
![y=-6x-1 \\ b=-1](https://tex.z-dn.net/?f=y%3D-6x-1%20%5C%5C%0Ab%3D-1)
The y-intercept is -1. The line crosses the y-axis at the point (0,-1).
Answer:
Perimeter is 17.07
Step-by-step explanation:
We know that DF = EF = 5 cm, since D and E are the midpoints of AC and AB, both of which are 10 cm in length.
We need to use the Pythagorean theorem to get the length of DE.
![DE = \sqrt{5^{2} +5^{2}}=\sqrt{50} = 7.07\\](https://tex.z-dn.net/?f=DE%20%3D%20%5Csqrt%7B5%5E%7B2%7D%20%2B5%5E%7B2%7D%7D%3D%5Csqrt%7B50%7D%20%20%3D%207.07%5C%5C)
So the perimeter of DEF is 5 + 5 + 7.07 = 17.07
