Answer:
Option: B is the correct answer.
B. 95040 codes
Step-by-step explanation:
There are a total of 12 characters which could be assigned.
The characters are:
0, 1, 2, 3, 4, 5, M, V, T, G, Y, or R.
We have to make a five-character code.
Also, none of the characters in the code could be repeated.
This means that we have to choose any 5 of the 12 characters and arrange them so as to get a code.
Hence, total number of such codes possible are given by the formula:
Hence, it is calculated as:

Answer:
Option A is correct.
is the equation represent the point slope form gives the plant's height at any time.
Step-by-step explanation:
Point slope intercept form: For any two points and
then,
the general form
for linear equations; where m is the slope given by:
Consider any two points from the table;
let A= (2 , 16) and B =(4, 32)
First calculate the slope of the line AB:
= 8
Therefore, slope of the line m = 8
Then,
the equation of line is:
Substitute the value of m=8 and (2, 16) above we get;
Therefore, the equation in point slope form which gives the plant's height at any time is; , where x is the time(months) and y is the plant height (cm)
