Question

Can some body help me for this problem, and thanks for the help

Answer 1

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%.

What is exponential decay?

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%.
