A colony of E. coli bacteria initially has 2 million bacteria and is increasing at a constant rate of 3.5% every minute. Write a formula for the number of bacteria in the colony after tt minutes.
Answers
The formula for the number of bacteria in the colony after t minutes is [tex]y=2000000(1.035)^t[/tex]
An exponential growth is in the form:
y = abˣ
where y, x are variables, a is the initial value of y and b > 1
Let y represent the bacteria population after t minutes
Given that initially has 2 million bacteria, hence:
a = 2 million = 2000000
It increases at a rate of 3.5% every minute, hence:
b = 100% + 3.5% = 1.035
The equation is:
[tex]y=2000000(1.035)^t[/tex]
Therefore the formula for the number of bacteria in the colony after t minutes is [tex]y=2000000(1.035)^t[/tex]

Step-by-step explanation:
x = 1 - i sqrt(2) ^ y = 10 + i sqrt(2)
x = 1 + i sqrt(2) ^ y = 10 - i sqrt(2)
Answer:
Step-by-step explanation:
y = 11 - x ----------(I)
y = 2x² - 4x + 6 -----------(II)
Substitute y = 11- x in (II)
11 - x = 2x² - 4x + 6
0 = 2x² - 4x + x + 6 - 11
0 = 2x² - 3x - 5
2x² - 3x - 5 = 0
Sum = -3
Product = -10
Factors = -5 , 2
2x² - 5x + 2x - 5 = 0
x(2x - 5) + (2x - 5) = 0
(2x -5 )(x +1)=0
2x - 5 = 0 ; x + 1 = 0
2x = 5 ; x = -1
x = 5/2
When x = -1 ; y = 11 - (-1) = 11 + 1 = 12
[tex]When x = \dfrac{5}{2} ; y = 11- \dfrac{5}{2}= \dfrac{22}{2}- \dfrac{5}{2}= \dfrac{17}{2}[/tex]
Solution: (-1 , 12) and (5/2 , 17/2)

Convert decimals to fractions
Answers
Answer:I’m not sure if you had a file if so it’s not there but heres something else
Step-by-step explanation:
Decimals can be written in fraction form. To convert a decimal to a fraction, place the decimal number over its place value. For example, in 0.6, the six is in the tenths place, so we place 6 over 10 to create the equivalent fraction, 6/10. If needed, simplify the fraction.

Justice needs 24 feet of fencing to surround his garden. The fencing is priced at $0.25 per inch how much will it cost justice to fence in his garden?
Answers
Answer:
66 dollars
Step-by-step explanation:
Justice needs $72 to fence in his garden.
What is Multiplication?
To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
Justice needs 24 feet of fencing to surround his garden.
The fencing is priced at $0.25 per inch.
Since, 1 foot = 12 inch
Hence, 24 feet = 24 x 12 inch = 288 inch.
Cost of the fencing in one inch = $0.25
So, Cost of the fencing in 288 inch = 288 x 0.25
= $72
Thus, Justice needs $72 to fence in his garden.
