In a business letter, the date line, which consists of the month, day, and year, is positioned two to six lines below the letterhead.
The exponent is greater than 1 so it is exponential growth, 500 in the equation represents the initial value, and the growth rate in the second equation is 6%.
<h3>What is exponential decay?</h3>
During exponential decay, a quantity falls slowly at first before rapidly decreasing. The exponential decay formula is used to calculate population decline and can also be used to calculate half-life.
We have an exponential function:

a) As the base of the exponent is greater than 1 so it is exponential growth.
b) 500 in the equation represents the initial value.
c) We have another exponential equation:

For exponentikal gropwth:
1 + r = 1.6
r = 0.6 or
r = 6%
In the equation:

The number of bacteria initially was 500 and from the second the number of bacteria initially was 800.
Thus, the exponent is greater than 1 so it is exponential growth, 500 in the equation represents the initial value, and the growth rate in the second equation is 6%.

Answer:
5
Step-by-step explanation:
For these types of problems, we can use cross - multiplication.
4/32 = x/40
Notice that since 40 and 32 are both measured in minutes, we put them on the same line.
Now, like the name suggests, we cross multiply the equation, by doing 4 * 40 = 32 * x. Now, we are left with 160 = 32x. After solving this, we get the answer 5.
