Step-by-step explanation:
Geometric Sequence formula for general term:
an = a1(r^n-1)
a1 = 4 × (-5)^1-1
a1 = 4
r = -5
Summation formula for geometric sequence :
Sn = a1 ( 1 - r^n / 1 - r )
...<em>take n from the top of the summation.</em>
= 4 ( 1 -(-5)^6 / 1 -(-5)
= -10416.
Answer:
1.54 [km²].
Step-by-step explanation:
1) the given scale is for linear functions, the given area of the lake is quadratic function. According to this
2) actual area = given area *50000 *50000;
3) the given area=0.000616 [m²],
the actual area=0.000616*50000*50000=1540000 [m²] or 1.54 [km²].
