What are the first five terms of the recursive sequence?

Reika [66]

Answer:

the fourth option

9, 30, 93, 282, 849

Step-by-step explanation:

a1 = 9

based on the sequence definition

a2 = 3×a1 + 3 = 3×9 + 3 = 27 + 3 = 30

the only answer option with a2=30 is the fourth one. all others must be therefore wrong.

check

a3 = 3×a2 + 3 = 3×30 + 3 = 93

a4 = 3×a3 + 3 = 3×93 + 3 = 282

a5 = 3×a4 + 3 = 3×282 + 3 = 849

confirmed.

If a 100 m. diameter wind turbine is exposed to 7 m/s wind with an air density of 1.25 kg/m what is the electricity produced by

Yuliya22 [10]

Answer:

electric energy = 980 J

Step-by-step explanation:

Given,

Diameter of wind turbine = 100 m

Speed of wind,v = 7 m/s

Density of air = 1.25 kg/m

Hence, the total mass of air enters into turbine =Speed of wind x Diameter of wind turbine

= 1.25 x 100

= 125 kg

Hence, total mechanical energy of turbine can be given by,

$E\ =\ \dfrac{1}{2}.m.v^2$

$=\ \dfrac{1}{2}\times 125\times 7^2$

= 3062.5 J

Efficiency of turbine = 32%

Hence,

total electric energy = 32% of mechanical energy

$=\dfrac{32}{100}\times 3062.5\ J$

= 980 J

So, the total electric energy produced by the turbine will be 980 J.
