Answer:
x=16
Step-by-step explanation:
First, minus 80 from 180 because the sum of all the angles in a triangle is 180. Then use linear equations. 100=(4x-4)+(0.5x+32)
After that, you will get 100=4.5x+28
x=16
To find the inverse, interchange the variables and solve for y.
f^−1(x)=−25+5x/2
5x+25 final answer is x=5

Answer:
The answer is "26179.4".
Step-by-step explanation:
Assume year 2000 as t, that is t =0.
Formula:

Where,

for doubling time,


Given value:



when year is 2000, t=0 so, year is 2100 year as t = 100.
