Are the graphs of 2x+7y=6 and 7y = 2x +6 parallel? Explain.
avanturin [10]
With questions like this (to see if theyre parallel), all you have to do is see if lines have a congruent slope. if yes (ex: 2 and 2), then they are parallel. if the slopes are opposites (ex: 4 and -1/4), then they are perpendicular. If they have no such relation (ex: -3 and 1/7), then they are neither.

with this problem, find the slope by separating the same variable in each equations, like this:

2x + 7y = 6
-2x            -2x

7y = -2x + 6

(the second equation is already separated) so now we have

7y = -2x + 6 and 7y = 2x + 6

since -2 does NOT equal 2, these two graphs/lines are NOT parallel.
Hope this helped!

Using chain rule, what is the derivative of sin(arcsin(x))
sergey [27]
Chain rule
y=f(g(x))
y´=(d f(gx)/d g)(d g/d x)

or

y=y(v)   and v=v(x), then dy /dx=(dy/dv)(dv/dx)

in our case:
y=sin (v)
v=arcsin(x)

dy/dv=d sin (v)/dv=cos (v)=cos(arcsin(x)
dv/dx=d arcsin(x)/dx=1/√(1-x²)

dy/dx=[cos (arcsin(x))]/√(1-x²)

Answer: d sin(arcsin(x))/dx=[cos (arcsin(x))]/√(1-x²)

18. Find two numbers whose L.C.M is 3965 and G.C.F is 61​
Artist 52 [7]

Answer:

305 and 793

Step-by-step explanation:

LCM * HCF = product

3965 * 61 = 241,865 = 5*13*61*61

HCF = 61 so

61*5 = 305

61 * 13 = 793
