Answer:
<h2>S.A. = 66m²</h2>
Step-by-step explanation:
Look at the picture.
We have :
4 rectangles 3m × 4m → A₁ = 3 · 4 = 12 m²
2 rectangles 3m × 3m → A₂ = 3 · 3 = 9 m²
Therefore the Surface Area of the rectangular prism is:
S.A. = 4A₁ + 2A₂
Substitute:
S.A. = 4(12) + 2(9) = 48 + 18 = 66
we are given
f(t) be the amount of garbage, in tons, produced by a city
t be the time in years after 2000
Since, f(t) is dependent on t
so, t is independent
and f(t) is dependent
f(4)=1458.6 means t=4 or 2004
and amount of garbage is 1458.6 tons
f(2)=1323 means t=2 or 2002
and amount of garbage is 1323 tons ...........Answer
