Sum of n terms = a1 (r^n-1/ (r-1)
Sum of first one = 3 * (4^5 - 1) / 3 = 1023
.. 2nd = 5 * (6^2 - 1) / 5 = 35
.. 3rd = 5 ^4 - 1 / 4 = 156
.. 4th = 4 * (5^4 - 1) / 4 = 624
So in increasing order its 2nd, 3rd, 4th and first.
Answer:
hypotenuse=0.869...
Step-by-step explanation:
soh cah toa
xy is the adjacent side
we are looking for the hypotenuse, which is yz
cos30=6/hypotenuse
0.866=6/hypotenuse
hypotenuse=0.869...
Hypotenuse squared is side square plus side squared. 10 squared is 2 x X squared. X is 5 root 2

I dont know what all those extra boxes are for but I hope I helped a little
The place value of 7 in 0.724 = 7 tenths or 7/10 or 0.7
The place value of 2 in 0.724 = 2 hundredths or 2/100 or 0.02
The place value of 4 in 0.724 = 4 thousandths or 4/1000 or 0.004
Therefore , the place value of 7 in 0.724 is 7 tenths or 7/10 or 0.7 ( as all are the same ) .
