In the late nineteenth century, the scientist Marie Curie performed experiments that led to the discovery of radioactive substan
gtnhenbr [62]

Answer:

Step-by-step explanation:

Half life is the time taken by a radioactive substance to reduce of half of its original size

If the half life of radium is 1600, this means that the original radioactive substance N0 have reduced to N0/2 after 1600 years

if we are given N0 = 1000grams

The amount of the substance that will remain after 1600 years will be N0/2 i.e 1000/2 = 500g

<em>Hence 500 grams of radium will be left after 600years</em>

The cost C, in dollars, to have medical records transcribed is a function of time, t in hours. A physician's group spends C(t) =
Contact [7]

Answer:

B. $39550

Step-by-step explanation:

The expression for the function is not well-formatted, find the correct format in the solution bellow

Step one:

given data

We are told that the function of the cost is

C(t) = 0.04t^3- 0.1t^2 + 5.5t

instantaneous rate c(t) is the value obtained when we plug in 100 for t in the function above

substituting we have

C(t) = 0.04(100)^3- 0.1(100)^2 + 5.5(100)\\\\\C(t) = 0.04*1000000- 0.1*10000 + 5.5*100\\\\C(t) = 40000-1000+550\\\\C(t) = 39550

$39550

The question has to do with scientific notation

<h3>What is scientific notation?</h3>

Scientific notation is the expression of a number in the form a ×  10ⁿ where 1 ≤ a ≤ 10 and n is an integer.

<h3>How to simplify the expression?</h3>

Now to simplify the expression (9 × 10⁻¹³) - (6.3 × 10⁻¹⁵) both number have to have the same exponent to the power of 10.

So, re-writing, we have

(9 × 10⁻¹³) - (6.3 × 10⁻¹⁵) = (9 × 10⁻¹³) - (6.3 × 10⁻¹³ × 10⁻²)

= (9 × 10⁻¹³) - (6.3 × 10⁻² × 10⁻¹³ )

= (9 × 10⁻¹³) - (0.063 × 10⁻¹³ )

= (9 - 0.063) × 10⁻¹³ )

= 8.937 × 10⁻¹³

So, simplifying the expression (9 × 10⁻¹³) - (6.3 × 10⁻¹⁵) = 8.937 × 10⁻¹³
