t = v√$\displaystyle s^2$+9

this is what im at help me if you can. many thanks

Assuming your equation is

$\displaystyle t = v\sqrt{s}^2+9$

then it can be re-written as

$\displaystyle t = vs+9$

as the square ad square root are opposites.

Now taking 9 from both sides

$\displaystyle t-9 = vs$

$\displaystyle vs= t-9 $

and dividing v

$\displaystyle s= \frac{t-9}{v} $

now s is the subject. - Nov 18th 2009, 12:40 AMdecoy808
im having problems geting the correct value.

the first part of the question was to find V? which i found to be 2

V= 2

T=10

S= 4

so making s the subject i should get answer 4?

s= t-9/v

4 = 10-9/2 - Nov 18th 2009, 01:07 AMaidan
