The half-life of a particular element is 10 days. If you begin with 40 grams of the element write an exponential decay function that models the decay of the element. Let t =1 represent one half life (or 10 days). How much of the element is left about 40 days?

2.25 grams

Step-by-step explanation:

To find the remaining mass of an element, apply the following:

m0 = m/(2^n), where m0 is the remaining mass, m as the original mass and n as the number of half lives that have passed.

we have m, we just have to find n. To find n,

24/6 = 4 half lives have passed.

Applying the first formula,

m0 = (36)/(2^4) = 36/8 = 2.25 grams

Hope this helps, brainliest would be appreciated :)

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
