Answer:
They are a transformation
Step-by-step explanation:
Checked using desmos graphing
Let 
, so that differentiating both sides wrt 
gives
If 
and 
, the above reduces to
This is the slope of the tangent line, which has equation
$10.99 , divide 54.99 by 5 to get 10.99 for each shirt
A factor of 30 is chosen at random. What is the probability, as a decimal, that it is a 2-digit number?
The positive whole-number factors of 30 are:
1, 2, 3, 5, 6, 10, 15 and 30.
So, there are 8 of them. Of these, 3 have two digits. Writing each factor on a slip of paper, then putting the slips into a hat, and finally choosing one without looking, get that
P(factor of 30 chosen is a 2-digit number) = number of two-digit factors ÷ number of factors
=38=3×.125=.375
$18.95 x 15/100 is equal to 2.84
18.95 - 2.84 is equal to $16.11
Hope that helped! :)
