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:

\rm  b_1(t) = 500(1.6)^t

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:

\rm  b_2(t) = 800(1.6)^t

For exponentikal gropwth:

1 + r = 1.6

r = 0.6 or

r = 6%

In the equation:

\rm  b_1(t) = 500(1.6)^t

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%.

Which of the following is another way to express the equation 16 = -9 + z?16 = z - 916 = z + 916 = - z - 916 = - z + 9
vivado [14]

Given the following equation:

16=-9+z

The given equation can be written using the commutative property

Where: a + b = b + a

So, the given equation can be written as follows:

16=z-9

So, the answer will be: 16 = z - 9
