Answer:
hypotenuse is 22.47 m
Step-by-step explanation:
The length of both legs of a right angle triangle are 8m and 21 m
We need to find the hypotenuse
To find hypotenuse we use Pythagorean theorem
Hypotenuse is AC and other two legs are AB and BC
Hypotenuse ^2 = 8^2 + 21^2
hypotenuse =
=
=
= 22.47
So the length of the hypotenuse is 22.47 m
Answer:
; {-3,-9, -27,- 81, -243, ...}
; {-3, 9,-27, 81, -243, ...}
; {3, 1.5, 0.75, 0.375, 0.1875, ...}
; {243, 81, 27, 9, 3, ...}
Step-by-step explanation:
The first explicit equation is
At n=1,
At n=2,
At n=3,
Therefore, the geometric sequence is {-3,-9, -27,- 81, -243, ...}.
The second explicit equation is
At n=1,
At n=2,
At n=3,
Therefore, the geometric sequence is {-3, 9,-27, 81, -243, ...}.
The third explicit equation is
At n=1,
At n=2,
At n=3,
Therefore, the geometric sequence is {3, 1.5, 0.75, 0.375, 0.1875, ...}.
The fourth explicit equation is
At n=1,
At n=2,
At n=3,
Therefore, the geometric sequence is {243, 81, 27, 9, 3, ...}.
