The mass of a radioactive substance follows a continuous exponential decay model, with the decay rate parameter 4% per day. A sample of this radioactive substance has an initial mass of 2.05 kg. Find the mass of the sample after four days. Round your answer to two decimal places.
The mass of the sample after four days is 1.75 kg.
How to find the mass of the sample after four days?The decay rate for a radioactive substance follows the exponential decay formula:
m(t) = m₀ * e^(-kt),
where m₀ is the initial mass, m(t) is the mass at time t, k is the decay rate parameter, and e is the base of the natural logarithm.
Given that the initial mass of the sample is 2.05 kg and the decay rate parameter is 4% per day, the formula becomes:
m(t) = 2.05 * e^(-0.04t).
To find the mass after four days, we substitute t = 4:
m(4) = 2.05 * e^(-0.04 * 4)
m(4) = 1.75 kg

What is an Equilateral Triangle?A triangle is said to be equilateral if each of its three sides is the same length.
In the well-known Euclidean geometry, an equilateral triangle is also equiangular, meaning that each of its three internal angles is 60 degrees and congruent with the others.
Given, Triangle QRS is an equilateral triangle.
QR is seventeen more than twice x ---> QR = 17 + 2x
RS is 19 less than six times x, ---> RS= 6x - 19
And QS is one less four times x, ---> QS = 4x -1
We have to find x and measure of each side.

Julio’s car can travel 300 miles on one 12-gallon tank of gas. Viet’s car uses gas as described by the equation m=13g
, where m is the miles traveled and g is the gallons of gas used. Which statement is true?
The true statement is "viet's car can uses 13 gallons of gas for every miles it travels.
The correct answer choice is option B.
Which statement is true?Julio's car:
m = k × g
Where,
m = miles traveled
g = gallons of gas used
m = k × g
300 = k × 12
300 = 12k
divide both sides by 12
k = 300/12
k = 12
So,
m = 12g
Viet's car:
m=13g
Therefore, the correct statement is viet's car uses 13 gallons of gas for every mile.

Which quick ratio is ideal?A good fast ratio is often anything greater than 1 or 1:1. If the ratio is 1:1, the company's liquid assets and current liabilities are equal in amount. A greater ratio means the business could more than cover its current liabilities.

What is the differentiation?The process of finding derivatives of a function is called differentiation in calculus. A derivative is the rate of change of a function with respect to another quantity.

f'(2)= [tex]\lim_{h \to \ 0}[/tex]((f(2+h)-f(2))/h)
Find the derivative using the chain and power rules.

f'(x) = [tex]\frac{1}{2(x+3)^{\frac{1}{2} }}[/tex]
f'(2)= [tex]\frac{1}{2(2+3)^{\frac{1}{2} }}[/tex]

Given is that a square piece of cloth with an area of 324 inches² is folded in half twice to form the napkin.
The area of the cloth is -

Let the side of the square cloth be {a}. So, we can write -
a² = 324
a = √324
{a} = 18 ... Eq { 1 }
The diagonal of the square will be the base length of the napkin (in the form of triangle). So, we can write -
