20 = 40e^-0.1446t
e^-0.1446t = 0.5
t = ln 0.5 / -0.1446
t = 4.8 days
Answer:
C. Move left
Step-by-step explanation:
By default, the equation of the parabola starts at (0,0) and you can see it clearly translates itself to the left by -3 units on the x-axis.
Sense the total would only be $38.12, we would then only want to find out how much would the book be, and that would be it. We would then want to add both how much the shirt and also the lunch was in total, and by doing this, we would the have to subtract this amount from the total that Shane has spent in total.

As we noted above, we then subtract both this total, and the amount that Shane has spent in this day.

Your answer: The book that Shane has purchased was a total of only
16.79.
16.79 would be your answer.

Answer:
(A) x=5
Step-by-step explanation:
- The length of the pool is 20 feet,
- The width is (20 minus x) feet; and
- The area of the pool is 300 square feet.
Area = Length X Width
300 =20(20-x)
Opening the bracket on the right hand side
300 =400-20x
20x=400-300
20x=100
Divide both sides by 20
x=5
The value of x=5
