Which recursive definition represents the sequence {2, 3, 5, 9, 17...}?

1 answer:

4 0

Let's analyze the sequence: {2,3,5,9,17...}.
3 = 2+1
5 = 3+2
9=5+4
17=9+8
So, every element of the sequence is obtained as sum from the previous element + (previous element -1)

y[n]=y[n-1] + (y[n-1]-1)

Manita carries a box of mass 40 kg. What is the weight of the box?( g=9.8m/s)<br>

Lilit [14]

Explanation:

Mass of boy = 40 kg

Mass of box = 20 kg

Total mass = 60 kg

Initial potential energy = 0 (since height would be 0 initially)

Final potential energy = mgh

Taking g as 10 m/s²,

=> 60 × 10 × 15

= 9,000 J

So, work done = final potential energy - initial potential energy

= 9,000 J

Power = Work/Time

=> Power = 9000/25

=> Power = 360 J/s

or 360 watt.

Find the equation of the line that is perpendicular to 3x + 2y = -2 and goes through the point (6,2)

notka56 [123]

Perpendicular lines have slopes that are inverse reciprocals of each other. That would give you the new slope in your equation. After that plug (6,2) into point slope form and solve to get your final equation.
