Answer:
(1)
type-A:
[tex]f(0)=1[/tex]
type-B:
[tex]g(0)=9[/tex]
(2)
[tex]t=0.746min[/tex]
Step-by-step explanation:
We are given
type-A:
[tex]f(t)=t+1[/tex]
type-B:
[tex]g(t)=9^{1-t}[/tex]
(1)
At initial means t=0
For type-A:
we can plug t=0
[tex]f(0)=0+1[/tex]
[tex]f(0)=1[/tex]
For type-B:
we can plug t=0
[tex]g(0)=9^{1-0}[/tex]
[tex]g(0)=9[/tex]
(2)
we can set f(t)=g(t)
and then we can solve for t
[tex]t+1=9^{1-t}[/tex]
we can draw graph of f(t) and g(t)
and then we can find intersection point
so, we got
[tex]t=0.746min[/tex]
