(y + 1)^3 would just be dividing the two

If you want it completely simplified, then it’s the following:

(y + 1)(y + 1)(y + 1)

= y^2 + y + y + 1 (y + 1)

= y^2 + 2y + 1 (y + 1)

= y^3 + y^2 + 2y^2 + 2y + y + 1

= y^3 + 3y^2 + 3y + 1

Approximately how many times greater is 2.3x10^-4 than 1.15x10^-8 ?

Minchanka [31]

Answer:

2.3 × $10^{-4}$ is 20,000 times greater than 1.15 × $10^{-8}$

Step-by-step explanation:

Given as :

The first number= x = 2.3 × $10^{-4}$

The second number= y = 1.15 × $10^{-8}$

Let The first number is z times greater than second number

i.e x = z × y

Or, z = $\dfrac{x}{y}$

Or, z = $\dfrac{2.3\times 10^{-4}}{1.15\times 10^{-8}}$

Or, z = 2 × $10^{4}$

∴ z = 20,000

So,The first number is 20,000 times greater than second number

Hence, 2.3 × $10^{-4}$ is 20,000 times greater than 1.15 × $10^{-8}$ . Answer

There are approximately 2.5 million deaths per year in country A. Express this quantity as deaths per minute.

MrRa [10]

2,500,000/365 = 6849 per day.
6849/24 = 285 per hour.
285/60 = 4.75 which is rounded to 5.
So 5 per minute

Hope this helps!

Answer:

t=19188.2 y

Step-by-step explanation:

The exponential decay equation is:

$A=A_{0}e^{-0.00012t}$ (1)

But, A is 10% of A₀, it means that A=0.10A₀.

If we put it into equation (1), we will have:

$0.10A_{0}=A_{0}e^{-0.00012t}$

$0.10=e^{-0.00012t}$ (2)

Now, we just need to solve (2) for t.

$t=\frac{ln(0.10)}{-0.000121} = 19188.2 y$

I hope it helps you!
