Answer:
Population of the city after 7 years from now, P(7) = 6370
Given:
Initial Population,
rate, r(t) = 1200 /yr
S(t) = [/tex]\frac{1}{1 + t}[/tex]
Step-by-step explanation:
Let the initial population be
The population after T years is given by the equation:
(1)
Thus, the population after 7 years from now is given by using eqn (1):
Answer:
The guy wire lenght is 500 ft.
Step-by-step explanation:
The Pythagorean Theorem says the sum of the squares two adyacent sides is equal to the square of the opposite side.
Applied in this example, we can rephrase it as:
The sum of the square of the pylon height with the square of the distance from the guy wire tip to the pylon is Equal to the square of the Guy wire lenght.
So:
