<em>Note: I am assuming we have to determine the value of the side 'x'.</em>

Answer:

The value of x = 8.1 units

Step-by-step explanation:

<em>Note: I am assuming we have to determine the value of the side 'x'.</em>

Given

Angle Ф = 32°

To determine:

x = ?

Using the trigonometric ratio

tan Ф = opposite / adjacent

here

Ф = 32°

opposite to angle 32°  = x

adjacent to angle 32° = 13

Therefore,

substituting adjacent = 13, Ф = 32°, opposite = x in the equation

tan Ф = opposite / adjacent

\tan \left(32^{\circ \:}\right)=\frac{x}{13}

\:x\:=\:13\:\times tan\:32^{\circ }\:

x = 8.1 units      tan 32° = 0.62

Therefore, the value of x = 8.1 units

A culture of bacteria has an initial population of 22000 bacteria and doubles every 5 hours. Using the formula P t = P 0 ⋅ 2 t d
Bas_tet [7]

We have been given that a culture of bacteria has an initial population of 22,000 bacteria and doubles every 5 hours. Using the formula P(t) = P_0\cdot 2^{\frac{t}{d}}, where P(t) ​ is the population after t hours, ​P_0 is the initial population, t is the time in hours and d is the doubling time.

We are asked to find the population of bacteria after 17 hours.

First of all, we will substitute our given values in doubling life formula as:

P(t) =22,000\cdot 2^{\frac{t}{5}}

Now to find population of bacteria after 17 hours, we will substitute t=17 in our formula as:

P(117) =22,000\cdot 2^{\frac{17}{5}}

P(117) =22,000\cdot 2^{3.4}

P(117) =22,000\cdot (10.556063286183)

P(17) =232233.392296026

P(17)\approx 232,233

Therefore, the bacteria population will be 232,233 after 17 hours.
