The population of bacteria can be modeled by the function below, where t represents the time since the population started decayi
Oksana_A [137]

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete. I will assume the function is:

f(t) = 15(0.86)^t

Required

Determine the rate of decay

In an exponential function f(x) = ab^x,

The decay rate of the function is calculated as:

1 - r = b

By comparison:

b = 0.86

So, the equation becomes:

1 - r = 0.86

Make r the subject

r = 1 - 0.86

r = 0.14

<em>The rate of decay is 0.14</em>

\bf \displaystyle\int~sec(4x-1)tan(4x-1)dx \\\\[-0.35em] ~\dotfill\\\\ sec(4x-1)tan(4x-1)\implies \cfrac{1}{cos(4x-1)}\cdot \cfrac{sin(4x-1)}{cos(4x-1)}\implies \cfrac{sin(4x-1)}{cos^2(4x-1)} \\\\[-0.35em] ~\dotfill\\\\ \displaystyle\int~\cfrac{sin(4x-1)}{cos^2(4x-1)}dx \\\\[-0.35em] ~\dotfill\\\\ u=cos(4x-1)\implies \cfrac{du}{dx}=-sin(4x-1)\cdot 4\implies \cfrac{du}{-4sin(4x-1)}=dx \\\\[-0.35em] ~\dotfill

oee [108]

Answer: Iron

Explanation:

The food contain high iron food as the daily value (DV) of the iron is 45% and most of the nutrient claimed that food contain low sodium but contain good source of the fiber. The food is high in the amount of the nutrient with 20% daily value.

The daily value actually recommend the minimum amount of the particular nutrient which everyone should consume in daily life.
