Answer:
The sum of next 8 terms is 292,968
Step-by-step explanation:
Here, the sequence is 3, 15, 75 , ...
Since the given term is in geometric progression, so
And here, r = 15/ 3 = 5
So, a = 3
r = 5
n = 8
So, sum of n terms of G. P
or,
= 292,968
Hence, the sum of next 8 terms is 292,968.
From Pythagorean Identities <span><span><span>sin^2</span>x</span>+<span><span>cos^2</span>x</span>=1</span>
and from that identities we can have <span><span>sinx</span>+<span>cosx</span>=1</span>, taking <span><span>sinx</span>=1−<span>cosx</span></span> and substitute in the equation
<span><span>sinx</span>+<span>cosx</span>=1</span>
<span><span>(1−<span>cosx</span>)</span>+<span>cosx</span>=1</span>
Remove the parenthesis
<span>1−<span>cosx</span>+<span>cosx</span>=1</span>
cancel <span>cosx</span>
<span>1=1</span>

Answer:
400
Step-by-step explanation:
25 times the length is 1000 m.
Let length = L
25L = 1000
L = 40
10 times the perimeter is 1000 m.
Let the perimeter = P
10P = 1000
P = 100
perimeter = 2L + 2W
2(40) + 2W = 100
80 + 2W = 100
2W = 20
W = 10
The length is 40 m, and the width is 10 m.
A = LW
A = 40 m * 10 m
A = 400 m^2
