According to this information, what was the percentage of carbon-14 remaining in an object after 55 years?

Option A that is is the correct choice.

Step-by-step explanation:

To find what percentage of carbon-14 is still remaining after years.

We have to pull the equation and instead of we will put the years in numbers that is

Lets see the equation.

Now to find the carbon-14 percentage.

Putting the value of in years.

So

and

As mentioned that the function is already framed to find the percentage we need not to convert it or multiply with .

So the percentage of C-14 remaining after years is

Option A is the correct choice.

then, the surface area of the sphere shown in the image is: 256π sq. units!

step-by-step explanation:

the lateral surface area of a sphere is 2πrh where h=2r.

then:

surface area = 4πr^2.

in this case, r=8 units ⇒ surface area = 4π(8 units)^2. = 256π sq. units!

then, the surface area of the sphere shown in the image is: 256π sq. units!

the cat is blue because the probability of extension towards the prefix of the diameter of the circle could only mathematically equal to the sum of the roots of the carrots from   your garden.
