Answer:
160
Step-by-step explanation:
finding the sum of all interior angles of the polygon:-
n is no of sides
=(n-2)*180= (18–2)*180=16*180=2880 degree.
One angle formula= sum/no of sides
Sum of all eighteen angles=2880,
One angle=2880/18=160 degree.
Answer:
The trip lasted 9 days.
Step-by-step explanation:
Area = Length x Width.
Length = 2+Width
(2+Width)(Width) = 143
2Width + Width^2 = 143
Width = 11cm
Length = 13cm, Width = 11cm

Answer:
- The function models exponential decay.
Step-by-step explanation:
Exponential function is:
- y = abˣ, where a- coefficient, b- base, x- exponent
When the coefficient is positive, the function is a growth if b > 1 and a decay if 0 < b < 1.
Given function has:
Since its coefficient is positive and base is between 0 and 1, it represents exponential decay.
