Answer: x=8
Step-by-step explanation:
8×8=64
First of all, you have to calculate slope of that,
m = (y2-y1)/(x2-x1) = (2-0)/(1-(-1)) = 2/2 = 1
Equation would be y-y1 = m(x-x1)
y-2 = 1(x-1)
y-2 = x-1
y = x+1 .... it is the final equation
Answer:
For 15 years - 
After 15 years - 
Step-by-step explanation:
We have that,
Initial population is 110,000 which grows by the rate 4% i.e. 0.04 for 15 years.
Since, the exponential growth is given by
,
where P is the initial population, r is the rate of interest and x is the number of years.
Thus, the required population is
i.e.
.
Moreover, after 15 years i.e. x+15 years, the population will be
.
Thus, the population after 15 years is
.
12-9=3
3+12+4,5=19,5
19 hours and 30 min
