Question

Can you please help me on e. f. and g.

Answer 1

His temperature was 100.1 degree farad initially which is around 6 pm. At 7 pm it became 101 degree farad.

`\begin{gathered} \text{slope = }(y_2-y_1)/(x_2-x_1)=(101-100.1)/(7-6)=(0.9)/(1)=0.9 \\ m=0.9 \end{gathered}`

y = mx + b

where

m = slope

b = y - intercept

let find the y intercept

`\begin{gathered} 101=0.9(7)+b \\ 101-6.3=b \\ b=94.7 \end{gathered}`

Therefore, the equation is

`y=0.9x+94.7`

e. let us draw a graph

His temperature will be critical above 22 minutes past 9 pm.

f . He should go to emergency room.

g.

`\begin{gathered} y=0.9x+94.7 \\ 98.6=0.9x+94.7 \\ 98.6-94.7=0.9x \\ 3.9=0.9x \\ x=(3.9)/(0.9) \\ x=4.33333333333 \end{gathered}`

His temperature will be normal around past 4 pm which is 98.6 degree farad.
