Answer: [tex]The[/tex] [tex]answer[/tex] [tex]is[/tex] [tex]C.[/tex] [tex]200[/tex]

Step-by-step explanation:

[tex]I ~can ~see ~that ~it ~does~ not ~appear ~to ~be[/tex] [tex]LINEAR[/tex]

[tex]y = 73e^kx[/tex] [tex]< ---~pulse~rate[/tex]

[tex].7[/tex] [tex]when[/tex] [tex]y = 155[/tex] [tex]< ---~sub ~in ~x[/tex]

[tex]155 = 73 e^(.7 * k)[/tex]

[tex]ln ( 155/73) = .7k[/tex]

[tex].75296567 = .7k[/tex]

[tex]k = 1.07567[/tex]

[tex]for[/tex] [tex]x = 0.9 :[/tex] [tex]pulse rate = y = 73 e^(1.07567[/tex] [tex]^. .9) = ~ 192[/tex]

[tex]Therefore~your~answer~is:~C.~200[/tex]
