Answer:
b = 5
Step-by-step explanation:
All quadratic equations are formed in the format of + bx + c = 0
Using this formula, we can re-arrange the equation to fit the given format. - 2 = -5x
+ 5x - 2 = 0
5 is plugged in for "b" in this equation, therefore b = 5.
Answer:
Option C. exponential decay function
Step-by-step explanation:
In this problem we have a exponential function of the form
where
y ---> is the money that is in the bank
x ----> number of days
a ---> is the initial value or y-intercept
b is the base of the exponential function
r ---> is the rate of change
b=(1+r)
In this problem we have that
Each day 1/2 of the money that is in bank value is removed
so
---> is negative because is a decreasing function
The value of b is equal to
The value of b is less than 1
b<1
That means -----> Is a exponential decay function
