Suppose the function ƒ(t) = et describes the growth of a colony of bacteria, where t is hours. Find the number of bacteria prese

aliya0001 [1]

Answer:

The number of bacteria present at 5 hours is 148.413

Step-by-step explanation:

Function: $f(t)=e^t$

This function describes the growth of a colony of bacteria, where t is hours.

We are supposed to find the number of bacteria present at 5 hours.

So, Substitute t = 5

So, the number of bacteria present at 5 hours = $e^5$

The number of bacteria present at 5 hours = 148.413

So, Option D is true

Hence the number of bacteria present at 5 hours is 148.413

3x = -12x + 50

15x = 50

x = 10/3

A sphere has a surface area of 36 pi. find the volume of the sphere

Vesna [10]

V ≈ 20.31

Answer:

20°

Step-by-step explanation:

These angles add up to 90° so we have:

x + 2x + x + 10 = 90

4x + 10 = 90

4x = 80

x = 20°
