Answer:
The value of x for the given expression is - 84
Step-by-step explanation:
Given expression as :
(x - 6) -
x = 3
Taking LCM of 3 & 4
So, = 3
or, 8 x - 48 - 9 x = 12 × 3
Or, 8 x - 9 x = 36 + 48
or, - x = 84
∴ x = - 84
Hence The value of x for the given expression is - 84 Answer
Given:
The scale factor between two circles is .
To find:
The ratio of their areas.
Solution:
We know that, all circles are similar.
The ratio of the areas of similar figures is equal to the ratio of squares of their corresponding sides or equal to the square of ratio of their corresponding sides.
The scale factor is the ratio of the corresponding sides.
Ratio of areas of circles = Square of scale factor between two circles
Therefore, the correct option is D.
Substituting into the ODE
gives
so that the coefficients of the series are given according to
We can shift the index in the recursive part of this definition to get
for . There's dependency between coefficients that are 2 indices apart, so we can consider 2 cases:
- If
, where
is an integer, then
but since , we have
and
for all
.
- If
, then
and so for all
. If
, we then have
and
.
So the ODE has solution
