<h3>There are 189 bacteria in 5 hours</h3><h3>There are 13382588 bacteria in 1 day</h3><h3>There are
bacteria in 1 week</h3>
<em><u>Solution:</u></em>
Given that,
A type of bacteria has a very high exponential growth rate of 80% every hour
There are 10 bacteria
<em><u>The increasing function is given as:</u></em>
Where,
y is future value
a is initial value
r is growth rate
t is time period
From given,
a = 10
<em><u>Determine how many will be in 5 hours</u></em>
Substitute t = 5
y = 189
Thus, there are 189 bacteria in 5 hours
<em><u>Determine how many will be in 1 day ?</u></em>
1 day = 24 hours
Substitute t = 24
Thus, there are 13382588 bacteria in 1 day
<em><u>Determine how many will be in 1 week</u></em>
1 week = 168
Substitute t = 168
Thus there are bacteria in 1 week
Answer:
(1, - 7 )
Step-by-step explanation:
To find a solution, choose any value for x, substitute into the equation and solve for y
Choose x = 1, then
y = - 3(1) - 4 = - 3 - 4 = - 7
Thus (1, - 7 ) is a solution to the equation

Answer:
Because 300 divided by 10 is 30
Step-by-step explanation:
If someone asks for 1/10 of a number, you are being asked to divide that number by 10. So, 1/10 of 300 = 300/10. 300/10 = 30. In other words, if you write 30 on a piece of paper 10 times and add it together, you'll get 300!
