Let n = 2548 + 147 and t = 0.23? Define a function h that determines n in terms of t. (Assume s > 0) Preview

Solution

(a)

Given that

n= 254s +147

and

t = 0.23 s²

this above equation can be written as

s² = t/(0.23)

s = (t/0.23) ........... where S0

Now

n = 254s +147

plug “s ” into above equation

n= 254 * (t/0.23) +147

this is the function h that determine n in terms of t

n =( 254/0.23) * t +147

Answer

(B)

Given that

5s +5t² = 18

and m = 7 t

from first equation

5t² = 18-5s

t² = 18/5 - s

t = (3.6 -s)

Now

Plug the t into m = 7 t

m = 7 ( (3.6 -s) )

above is the function k that determine m in terms of s

m= 7 ( (3.6 -s) )
