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

Using the inequality
2.50x + 3.50y ≤ 30
substituting y with the number of cheeseburgers sold
2.5x + 3.5(4) ≤ 30
x = 6.4
The maximum number of hamburgers he can sell is 6
