Write the inequality and graph to show that temperature at which the bacteria survived. 鈥淏acteria in , Apollo astronauts found a small colony of streptococcus bacteria that had apparently travelled unprotected to the moon on the surveyor spacecraft鈥檚 TV camera about three year earlier. The bacteria survived at temperatures as low as 鈥�.
Short Answer
The temperature at which the bacteria survived is .
Step by step solution
Step -1 - Apply the concept of Linear inequalities
In this type of question, Simply use the concept of understanding the question very carefully and then taking a variableand with accurate symbol >,< make a suitable inequality.
Step -2 – Finding the inequality by explaining the statement
Since, The bacteria survived at temperatures as low as .
From the above statement it is clearly seen that the bacteria can only survived as low as or equal to .
Step- 3 – Make the expression of the inequality
Now, assume that t is the temperature where the bacteria survived.
Hence, the inequality of the statement is .
Graphical Interpretation
Following is the graph of the expression to get the proper graphical representation to know the points.
Here, the value of t is greater than or equal to .
