1 hour = 60 mins = 3600 sec
-
6 sec = 1 flash
3600 sec = 3600 ÷ 6 = 600 flashes
-
Answer: 600 flashes
Answer: $1.07
Step-by-step explanation: When solving this problem the first item that you need to know is that 1 gallon = .264 liters
The calculate the cost per liter you need to multiply the cost per gallon times the decimal value of a liter.
Cost per liter = $4.07 x .264
Cost per liter = $1.07
The given function presents a local minimum in the coordinates (0,-1).
<h3>Factoring</h3>
In math, factoring or factorization is used to write an algebraic expression in factors. There are some rules for factorization. One of them is a factor out a common term for example: x²-x= x(x-1), where x is a common term.
For solving this question, the given equation should be rewritten from the factoring.
. Then, you have 3 equations.
From the Zero Factor Principle, you can write
Equation 1
(x+1)²=0
x+1=0
x= -1
Equation 2
x-1=0
x=1
Equation 3
x²-x+1=0

From these points it is possible to plot a graph and you can see that the local minimum presents the coordinates (0,-1).
