Given that,

It is known as exponential decay when a population or group of something is deteriorating and the quantity of decline is proportional to the size of the population. In an exponential decay, the overall value falls but the percentage that departs stays the same throughout time.

The exponential decay formula aids in determining the exponential drop, which is a rapid reduction over time. To calculate population decay, half-life, radioactivity decay, and other phenomena, one uses the exponential decay formula.

The standard  formula for this type of behavior which is written below:

A = [tex]Pe^{-rt}[/tex]  

Where

A refers the amount left after time t

P refers the initial amount at t = 0

r refers the rate

Here we have given that the mass of a radioactive substance follows a continuous exponential decay model, with a decay rate parameter of per day.

A sample of this radioactive substance was taken after two days.

And we need to find if the sample has a mass of today, then the initial mass of the sample.

Now, we have to substituting the values,

Let us assume,

P = 9575 kg

r = 0.12

t = 1

Then we get the equation as,

A = (9575 kg) [tex]e^{-0.12*1}[/tex]

When we simplify this one, then we get,

A = (9575 kg) [tex]e^{-0.12}[/tex]

A = (9575 kg) 0.886

A = 8483.45 kg

Therefore,

The initial mass of the sample after two days = 8483.45 kg

By choosing some items from a set and creating subsets, permutation and combination are two approaches to represent a group of objects. It outlines the numerous configurations for a particular set of data.

Permutations are the selection of data or objects from a set, whereas combinations are the order in which they are represented. Both ideas are critical to mathematics.

Contrary to permutations, the order of selection is irrelevant when choosing elements from a collection using the combination method. The number of combinations can be counted in simpler situations. Combination is the taking together of n items, k at a time, without repetition.

The solution of the system of equations:

x = 2y+  3

4x - 5y = 9

Is x = 1, y = -1.

Here we have the following system of equations:

x = 2y+  3

4x - 5y = 9

To solve it, we can notice that the variable x is already isolated on the first equation, then we can take it and replace it on the other equation, then we will get:

4*(2y + 3) - 5y = 9

Now we can solve that equation for y:

4*(2y + 3) - 5y = 9

8y + 12 - 5y = 9

8y - 5y = 9 - 12

3y = -3

y = -3/3

y = -1

And the value of x is:

x = 2y + 3

x = 2*(-1) + 3

x = -2 + 3 = 1

So the solution is x = 1 and y = -1.

Option 3:  the function that goes through the point (3, 5) is f(x-5)-1

Step-by-step explanation:

To find which function goes through the point (3, 5), we can substitute 3 for x and solve for the value of f(x).

For option 1, f(x-5)+1, we have:

f(3-5)+1 = f(-2)+1 = 6+1 = 7

For option 2, f(x+5)-1, we have:

f(3+5)-1 = f(8)-1 = ?

For option 3, f(x-5)-1, we have:

f(3-5)-1 = f(-2)-1 = 6-1 = 5

Answer:

To determine how many miles Naomi's car can go on one gallon of gas, we first need to determine how many gallons of gas the car used to travel 15\tfrac{1}{2}15 2 1 ​ miles. We are told that the car used \frac{2}{5} 5 2 ​ of a gallon to travel this distance, so we can multiply this value by 15\tfrac{1}{2}15 2 1 ​ to get the total number of gallons used:

\frac{2}{5} \cdot 15\tfrac{1}{2} = 9

Therefore, the car used 9 gallons of gas to travel 15\tfrac{1}{2}15 2 1 ​ miles. To determine how many miles the car can go on one gallon of gas, we need to divide the total number of miles traveled by the number of gallons used:

15\tfrac{1}{2} \div 9 = \frac{31}{18}

This means that the car can go 31/18 miles on one gallon of gas. Since this fraction is not in simplest form, we can further simplify it by dividing the numerator and denominator by the greatest common factor, which is 3:

\frac{31}{18} \div \frac{3}{3} = \frac{31}{18} \cdot \frac{3}{3} = \frac{31 \cdot 3}{18 \cdot 3} = \frac{93}{54}

Therefore, the car can go 93/54 miles on one gallon of gas. This fraction can be further simplified by dividing the numerator and denominator by the greatest common factor, which is 1:

\frac{93}{54} \div \frac{1}{1} = \frac{93}{54} \cdot \frac{1}{1} = \frac{93 \cdot 1}{54 \cdot 1} = \frac{93}{54}

Therefore, the final answer is that the car can go 93/54 miles on one gallon of gas.
