Rory is staying in a cabin on a hill 300 feet above sea level. she walks down the hill to the water’s edge. the equation of her average change in elevation over time is e = 300 – 10t, where t is the time in minutes since she left the cabin, and e is her elevation with regard to sea level. which values are viable points, and what are their values in the table relating t and e?

Answer with explanation:

If we draw a Vertical number line, Where Sea level Represents=0,

Point on number line where Rory is standing = +300 feet

Equation of average change in elevation over time is given by equation:

    e = 300 - 10 t

So, when t=0, e=300

and, when e=0 , gives ,

10 t= 300

→→Dividing both sides by 10

  t =30

→Average change

→Rate of change

Viable points →

e (feet)              300          0

t (minutes)          0            30

The equation of her average change in elevation over time is e = 300 – 10t, where t is the time in minutes since she left the cabin, and e is her elevation with regard to sea level. Which values are viable points, and what are their values in the table relating t and e?

a = not viable

b = 265

c = 0

Got it right on edg. 2020, hope this helped! :)

step-by-step explanation:

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
