Answer:
After population (A) = 62,902 (Approx)
Step-by-step explanation:
Given:
Current population (P) = 19613
Number of years (n) = 2020 - 2000 = 20 year
Rate of growth (r) = 6% = 0.06
Find:
After population (A)
Computation:
Given
12 meters tall airplane
18 meter shadow of airplane
6 meter shadow of jet
Find the measurement of the jet (y)
Solution
6y = 12 + 18 30
----- --------- ----> y = ------- -----------> y= 5
6 6 6
The answer is 5 meters tall is the measurement of a parked jet.
A mixed number is a fraction but if you want it as a improper fraction, multiply the denominator by the unit so,
4*3=12
add 1 (from the numerator)
12+1=13
Your fraction would be 13/3 because the denominator stays the same.
y = -8x + 5
To obtain the equation we require a point on it and it's slope.
the slope m = dy/dx at x = 1
dy/dx = -2-6x
x = 1 then dy/dx = -2 -6 = -8
equation of line in form y - b = m(x-a) with m = -8 and (a,b)=(1,-3)
y + 3 = -8(x-1)
y + 3 =-8x + 8
⇒ y = -8x +5 is the equation of the tangent

Answer:
48°
Step-by-step explanation:
The relevant trig relation is ...
Sin = Opposite/Hypotenuse
sin(α) = (350 m)/(470 m) = 35/47
α = arcsin(35/47) ≈ 48.13°
The angle of elevation of the plane is about 48°.
