Answer:
The spy must have at the start the amount of $1,024 in order to escape
Step-by-step explanation:
Let
a ------> amount of money that the spy must have at the start to escape
y ----> the remaining money
x ----> the number of guards
In this problem the remaining money is going to be reduced by half, every time the spy passes through a guard, so we can use an exponential function of the form

where
a is the initial value (amount of money at the start)
b is the base
b=(1-r)
r is the rate of decay
In this problem we have
r=50% -----> r=0.50
The value of b is
b=(1-0.50)=0.50
substitute

we know that
In order to escape after the fourth guard the amount of money remaining must be equal to $64
so
For x=4, y=$64
substitute in the equation and solve for a




therefore
The spy must have at the start the amount of $1,024 in order to escape
Answer:
Decimal Form: x= 0.142857
Exact Form: x= -1/7
Step-by-step explanation:
Let 5w equal the length and w equal the width.
5w + w = Area
6w = Area
5(20) = Length
Length = 100 inches
Answer:
She can ride 17.045 Miles in one hour.
Step-by-step explanation:
(250 feet/10 seconds) x (1 mile/5280 feet) x (60 seconds/ 1 minute) x (60 minutes/ 1 hour) = 17.045 Miles per hour
