Answer:

$x$ =7.5

Step-by-step explanation:

There are 15 ones so you have to add all of them up to get 15.

Then there are two $x$ 's to you have to add them to get $2x\\$ .

15-2 $x$

Lastly, divide both sides by 15 to get $x$ =7.5

Hope this helps!

Suppose that the amount, in grams, of polonium 210 present in a given sample is determined by the function defined by A(t)equ

ozzi

Answer:

The amount present in a sample of 401 grams after 25 years is $180\ g$

Step-by-step explanation:

we have

A(t) -----> the amount, in grams, of polonium 210 present in a given sample

t -----> the time in years

$A(t)=401e^{-0.032t}$

we know that

To find out the amount present in a sample of 401 grams after 25 years, substitute the value of t=25 years in the equation and solve for A(t)

For t=25 years

$A(25)=401e^{-0.032(25)}$

$A(25)=180.18\ g$

Mathematically, that would just be the product of the beads and the diameter of each bead

Hence, we have

10,000 * 0.4 = 4,000 cm
