The answer to the question is 30
5integer 0/1 is the mixed fraction of 5 units
Answer:
4
Step-by-step explanation:
Every year, the world grows by 1.1%. Converting to a decimal, we can divide by 100 to get 1.1% = 0.011. This means that the world grows by 0.011 exponentially each year. To put this into an expression, we can add 1 to our percentage to get 1.011. This represents 1 = 100% (the original population) and the growth of 1.1% = 0.011. We multiply the rate including the growth by the population to get the population after one year. After the first year, we have
population * 1.011 as the new population after one year. We do that for every year, so the second year's population is population*(1.011)*(1.011) and so on. If x represents the amount of years, then the population can be represented as
(original population)*1.011ˣ
Therefore, to get from 7 billion to 7.31 billion, we have
7 billion * 1.011ˣ = 7.31 billion
divide both sides by 7 billion to relatively isolate the x
1.011ˣ = 7.31/7
Another way of writing this is
log (base 1.011) (7.31/7) = x
≈ 3.96
Rounding to the nearest whole number, we get 4 as our answer
Answer:
See below.
Step-by-step explanation:
I'll work it out myself, then we should be able to see the mistake:-
6 ∛ (64x^5y^9)
= 6 * 4 * x^(5/3) * y^3
= 24 x^(3/3) * x^(2/3) y^3
= 24 x y^3 ∛(x^2)
You've got confused withe the cube root (∛) on the first line. You've interpreted it as ' 3 times the square root' so you were on the wrong road from the beginning.
Note that y^9 has cube root y^(9/ 3) = y^3 and x^5 has cube root of x^(5/3). The square root of x^9 is x^(9/2).
