Suppose that y is inversely proportional to square root of x.
FromTheMoon [43]

Answer:

i) k = 36.8

ii)y = 36.8/square root of x

iii)y = 1.4

Step-by-step explanation:

If y is inversely proportional to square root of x;

then the two variables are related by,

y = k/ square root of x

i)Value of k when...x = 8 and y = 13,

substitute into the equation above..so as to find the value of k

13 = k/square root of 8

;k = 13 × square root of 8

;k = 36.8

ii)Then substitute the value of k with...36.8

y = 36.8/square root of x

iii)If x = 27...then y =;

y = 36.8/27

y = 1.4

if the population of a country increases at a rate of 1.5% annually, and it’s current population is 430,000, how many years will
aleksandrvk [35]
Hi,
a_0=430000\\
a_1=a_0*1.15\\
a_2=a_1*1.15=a_0*1.15^2\\
...\\
a_n=a_0*1.15^n\\

a_n \geq 3*a_0\\

1.15^n \geq 3\\

n*ln(1.15) \geq ln(3)\\

n \geq  \dfrac{ln(3)}{ln(1.15)} \\

n \geq 7.86059688...\\\\

\boxed{n \geq 8}\\
