Answer:
irrational numbers
Step-by-step explanation:
irrational numbers
Let m = miles
let c = cost
Create a system of equations.
taxi company 1: c = $1.20m + $2
taxi company 2 c = $1.40m + $1
Set both equations equal to each other to solve for variable m.
$1.20m + $2 = $1.40m + $1
Subtract $1.20 from both sides and Subtract $1 from both sides.
$1 = $0.20m.
Divide each side by $0.20.
5 = m.
Plug 5 into one of our original equations for m.
c = $1.20(5) + $2.
Simplify the right side of the equation
c = $8
In conclusion, c = $8 and m = 5
She is starting at 4000, so that is the y-intercept of the graph. She is descending at 40 feet per minute, so her rate of change or slope is -40. The graph would look like this:
Answer:
It is given that : 
As we have to find the Domain of
.
-1 ≤ sin x ≤1

So it is defined for x lying between
.
As meaning of Domain is those values of x for which any function f(x) is defined.
