The decay factor for the annual rate of change of - 55 % is 0.45.
A quantity must vary by a specific percentage each time period in order for growth or decay to be exponential.
With the function displayed to the right, you may represent exponential growth or decay.
A(x) = a( 1 + r)ˣ
Where A is the amount after x time periods, a is the initial amount, x is the number of time periods, and r is the rate of change.
Now, we have the annual rate of change as:
r = - 55 % = - 55 / 100 = - 0.55
From the function A(x) = a( 1 + r)ˣ , the corresponding factor is 1 + r.
So, let B = 1 + r
B = 1 + r
B = 1 + (- 0.55)
B = 1 - 0.55
B = 0.45
Now, the value of B is less than 1 therefore, the corresponding decay factor is 0.45.

you can easily solve it by equating the fractions 4/13 and x/91
here, we suppose x as the number of people who can bowl.
4/13=x/91
or, 4/13×91=x (divide 91 by 13)
or, x=4×7
therefore, x=28
easy peesy lemon squeezy ;-)
Answer:
r = 10
Step-by-step explanation:
Solve for r by simplifying both sides of the equation, then isolating the variable.
