Answer:
238375 years
Step-by-step explanation:
The equation for annual sales of product q is given as :
Annual sales of product q = (1/2)0.8t
Where t is time in years
We were asked to find in how many years that the annual sales would be 95350.
So we have,
95350 = (1/2)0.8t
95350 = 0.4t
Divide both sides by 0.4
We would have:
t = 95350 ÷ 0.4
t = 238375 years.
Therefore, the number of years after which the annual sales would be 95350 is 238375 years.
Answer: civil protection is an effort to protect the citizens of a state (generally non-combatants) from military attacks and natural disasters. It uses the principles of emergency operations: prevention, mitigation, preparation, response, or emergency evacuation and recovery.

Answer:
the answer is 3
Step-by-step explanation:
Answer:
x=-4, y=7
Step-by-step explanation:
According to the first equation, y = -4x - 9, so we can substitute y in the second equation for -4x - 9.
y = 3x + 19
-4x - 9 = 3x + 19
Add 9 to both sides
-4x = 3x + 28
Subtract 3x
-7x = 28
Divide by -7
x = -4
Plugging this into the equation, we have:
y = -4x - 9
y = -4(-4) - 9
y = 16 - 9
y = 7
Let x- intercept represents time
Let y-intercept represents population
Let 1990 represent initial year
Points are (0,14.2)(10,12.4)
slope m= 
= 
General linear equation
y= mx+b --------------(i)
here m is slope and b is intercept
plug the 1st point in equation
14.2= -0.018(0) + b
b=14.2
y= 0.018x + 14.2
replace y with p(t) and x with t
p(t) = -0.018t + 14.2
