Answer:
A.28
Step-by-step explanation:
Substitute a with 28 so:
-6+28=22
Then simplify the equation:
22=22
There are (A) 2.7 bacterias initially.

What is a function?</h3>
- A function is an expression that establishes the relationship between the dependent and independent variables.
- A function from a set X to a set Y allocates exactly one element of Y to each element of X.
- The set X is known as the function's domain, while the set Y is known as the function's codomain.
- Originally, functions were the idealization of how a variable quantity depends on another quantity.
To find the number of bacteria:
- The graph shows that the function follows an exponential curve, and the starting point is at ( 0,2.7 ).
- The starting number of bacteria is then 2.7.
Therefore, there are (A) 2.7 bacterias initially.

(C) 4
<u>Answer-</u>
The equations of the locus of a point that moves so that its distance from the line 12x-5y-1=0 is always 1 unit are

<u>Solution-</u>
Let a point which is 1 unit away from the line 12x-5y-1=0 is (h, k)
The applying the distance formula,








Two equations are formed because one will be upper from the the given line and other will be below it.
