Katyanochek1 [597]

Answer:

(a) $X(t)=X(0)+\Delta X*t=5-0.5*t$

(b) $X(t)=X(0)+\Delta X*t=1+0.5*t$

Step-by-step explanation:

a) For the students, they start at X(0)=5 h and ΔX=-0.5 h/week.

We can write

$X(t)=X(0)+\Delta X*t=5-0.5*t$

b) For the professors, they start at X(0)=1 h and ΔX=+0.5 h/week.

We can write

$X(t)=X(0)+\Delta X*t=1+0.5*t$

c) The seew which they will be watching the same amount of hours will be the 4th week.

$X(t)=5-0.5*t=1+0.5*t\\\\5-1=(0.5+0.5)*t\\\\t=4\, weeks$

The amount of hours will be

$x(4)=1+0.5*4=1+2=3\,hours$

Hamid has gained weight. He now weights 88kg, which is 10% higher than his normal weight. What is Hamids normal weight

Divide his weight now by 110% to find his normal weight.

88/1.1 = 80

His normal weight is 80 kg
