We will see that the exponential decay function is:
f(x) = 175*(0.8)^x
<h3>
How to find the exponential decay?</h3>
The general exponential decay is:
f(x) = A*(1- r)^x
Where:
- A is the initial value.
- r is the rate of decay in decimal form.
- x is the variable, in this case is the time.
Here we know that the initial value is 175, and the rate of decay is 20%. To get this in decimal form, we just divide it by 100%.
20%/100% = 0.2
Replacing that in the exponential function, we get:
f(x) = 175*(1 - 0.2)^x
f(x) = 175*(0.8)^x

Answer:
a 300 miles
Step-by-step explanation:
4.5 inches = 3×1.5 inches
so
4.5 inches = 3×100 miles = 300 miles
REQUIRED:
Round to 3 decimal placed the value of the irrational number e.
Step-by-step solution/explanation;
The letter e in mathematics is also known as the Eular's number and is a mathematical constant used in many calculations especially natural logarithms of numbers.
The value of the Eular's number is approximately;

It can continue till infinity, however approximations of this number is always used to avoid unnecessary complications.
Therefore, rounded to 3 decimal places, the value of e is now;
ANSWER:

Note that we take 3 digits aftre the decimal and then if the fourth digit after the decimal is 5 or greater than 5, we make it 1 and add that 1 to the third digit after the decimal. Otherwise we simply make it zero and cancel it along with all other digits after it.
The digit that follows 8 (third digit) is less than 5, therefore, we write it off along with all other digits after it, and we are left with the decimal point and then ...718.
Option C is the correct answer.

Step-by-step explanation:
Philip is 5 years old and Jon is 19 years old now.
Step-by-step explanation:
Step 1 :
Let x be the age of Philip Now
Since Jon is 14 years older than Philip,
Age of Jon = 14 + x
Step 2 :
After 2 years,
Age of Philip = x+ 2
Age of Jon = 14+x+2 = 16+x
Step 3 :
Given that in 2 years, Jon will be 3 times as old as Philip.
So we have 16 + x =3(x+2)
=> 16 + x = 3x +6
=> 2x = 10 = x = 5
Hence age of Philip is 5 years
Age of jon = x + 14 = 5+ 14 =19 years
