Question

F x a
If f =72 when a =9 find,
A when f = 56​

Answer 1

a = 7, when F = 56

Step-by-step explanation:

From the given question,

F = xa ............. 1

⇒ x =
`(F)/(a)` ................. 2

when F= 72 and a = 9,

substitute the values of F and a in equation 2, to have;

x =
`(72)/(9)`

= 8

x = 8

Thus, the value of a when F = 56 can be determined as follows;

From equation 1,

a =
`(F)/(x)` ................... 3

=
`(56)/(8)`

= 7

a = 7

The value of a is 7.
