Total power generated by wind worldwide doubles every 3 years. In a particular year, the world wind-generating capacity was abou
NeTakaya
This is a problem of doubling time, the general formula for doubling time is

N = A(2)^( t /d)
where N is the future wind generating capacity in thousand MW
A is the initial wind generating capacity which is 95,000 MW
d is the time it will double, which is 3 years
t is the time in the future in years

N = 95(2)^( t / 3) is the formula for t<span>he continuous growth rate and give a formula for wind generating capacity W W (in thousand megawatts) as a function of t t , the number of years in the future</span>

katrin [286]

Answer:

x = 3, x = 0

Step-by-step explanation:

To solve these factored equations, just divide each part by zero and solve.

2x(x-3) = 0 → (x-3) = 0, and 2x = 0.

(x-3) = 0 → x - 3 + 3 = 0 + 3 → <u>x = 3.</u>

2x = 0 → 2x/2 = 0/2 → <u>x = 0.</u>

Luba_88 [7]

Answer:

Step-by-step explanation:

So let's factor!

Let's see whats this about...

3x^{3} +15x^{2} +18x\\3x(x^{2} +5x+6)\\3x(x-1)(x+6)

So, there you go!

sorry if this did not make sense...

What I did was essentially factor out 3x first, and then factor the second product by grouping.

Hope this Helps!

P.S. Stay Safe!

0.9(x+1.4)−2.3+0.1x=1.6
IgorC [24]

so what you do is  distribute the 0.9 to x and 1.4 to get 0.9x+1.26 then combine like terms 1.9x - 1.04= 1.6 then add 1.04 to both sides to get 1.9x = 2.64 divide 1.9 to both sides


answer:1.389 and if you round 1.39
