Answer:
Step-by-step explanation:
Let's retype that as y = b^x. The inverse of this function is log y = x
b
which you could also write as y = ln x
b
If you had y = e^x, the inverse function would be y = ln x.
Note that if you let ln x be the input to y = e^x, the result would be just 'x,' which confirms that these two functions are inverses of one another.
Answer:
The numbers of boys in one grade are 60 .
Step-by-step explanation:
As given
In one grade of 150 students .
The ratio of boys to girls is 2:3.
Let us assume that the scalar multiple of boys and girls be x.
Thus number of boys = 2x
Number of girls = 3x
Than the equations becomes
2x + 3x = 150
5x = 150
x = 30
Thus number of boys = 2 × 30
= 60
Therefore the numbers of boys in one grade are 60
