Step-by-step explanation:
the line with the equation y=-×-3 has slope -1
the line perpendicular to the given line and which passes through the point (-4,-2) has equation y-2(-2)=(1)(×-(4))
y+2=×+4
y=×+2

Answer:
The population is expected to double in 36 years
Step-by-step explanation:
According to the the rule of 72,
A value is doubled if the product of the annual rate and number of years is 72,
Given,
The annual rate of interest = 2%
Let x be the time in years after 1965,
By the above statement,
The population will double if,
x × 2 = 72 ⇒ x = 36
Hence, the after 36 years since 1965 the population will be doubled,
i.e in 2001. ( ∵ 36 years after 1965 )
