Answer:
80.
Step-by-step explanation:
Three digit number can only have three patterns
A. All digits are distinct
B. Two digits are same and third is different
C. All three digits are alike.
We need to calculate B
that is B= Total- A-C
Total numbers from 700 to 999= 299.
Number numbers having all digits distinct = 3×9×8= 216 ( first digit can have only three digits 7,8,9)
All three are alike = 3 ( 777,888,999).
So, 299 -216-3= 80.

Answer:
The derivative of the function is 3.
Step-by-step explanation:
The derivative of
is
. The derivative of 20x is 20, for example. The derivative of
is
.
In this problem
It aks the derivative of a function, which is 3x. Applying the rule that is explained above, we have that the derivative of 3x is 3.
So the derivative of the function is 3.
