Answer:
4378
Step-by-step explanation:
Its clearly given that each term is multiplied by 3
I.e- 2×3 = 6
6×3= 18
and so on....
so here the G.P series is a=2 and r=3
To find the 8th term ar^8-1
ar^7 = 2×3^7
= 2×2187
= 4378
Answer:
5y - 2x = 0
Step-by-step explanation:
Equation of line is given by,
y - y1 = ( x - x1 ) ( y2 - y1)/ (x2 - x1 )
y - 0 = ( x - 0 ) ( 2 - 0 )/ ( 5 - 0 )
y = 2x /5
5y = 2x
5y - 2x = 0
This is the required equation.
If the length of the ladder is x then 12/x=cos70, so x=12/cos70=35’ approx, answer c.
