Answer 1

Answer:

C.Output peripheral

Step-by-step explanation:

There are two concentric circles of radius 5cm and 9cm. The length of tangent PB = 10√2 cm then the length of the tangent PA is *

Answer 2

Step-by-step explanation:

Let

f(x, y, z, p, q) = 0, (1)

We relate this equation to

F(x, y, z, p, q) (2)

Then we have the system of Charpit’s auxiliary equations as

dx

−fp

=

dy

−fq

=

dz

−pfp − qf(q)

=

dp

fx + pfz

=

dp

fy + qfz

=

F
