Answer:
Step-by-step explanation:
Given that prices for a pair of shoes lie in the interval
[80,180] dollars.
Delivery fee 20% of price.
i.e. delivery fee will be in the interval [4, 9]
(1/20th of price)
Total cost= price of shoedelivery cost
Hence f(c) = c+c/20 = 21c/20
The domain of this function would be c lying between 80 to 180
So domain =[80,180]
---------------------------------
Amount to be repaid = 42 dollars
Once he received this amount, the price would be
105+42 =147
But since price range is only [21*80/20, 21*180/20]
=[84, 189]
Since now Albert has 147 dollars, he can afford is
[80,147]
6 1/4 because 9 1/2 - 3 1/4= 6 1/4
You can also use the distance formula
Answer:
x = 0.1116 (rounded to 4 decimal places)
Step-by-step explanation:
We need to isolate "e" first, so we do:

Solving these types of equations requires us to take the Natural Logarith (Ln) of both sides, so we have:

We can use the property of logarithms shown below to further simplify:

So, we have:

We know Ln(e) = 1, thus now, we can replace it and solve for x:

So
x = 0.1116 (rounded to 4 decimal places)
<em>The answer is TRUE. </em>
