lyudmila [28]

Answer:

10.8 minutes

Step-by-step explanation:

Given data

We are told that the number of Jugs is 18

Filling the first 3 jugs has taken 5 minutes

let us find the filling rate

Rate= 3/5

Rate= 0.6 Jugs per minute

Hence the rate of filling is 0.6 Jugs per minute

Therefore the time take to fill the remaining 16 jugs is

TIme= Rate*Number of Jugs

TIme= 0.6*18

Time= 10.8 minutes

<em>The distributive property</em>:

<em>a(b + c) = ab + ac</em>

-\dfrac{1}{2}(4-6x)=\left(-\dfrac{1}{2}\right)(4)+\left(-\dfrac{1}{2}\right)(-6x)=-2+3x

Which function is the inverse of f(x)= B^X
Scrat [10]

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.
