What is the rate of decay for the function f(x) =2(0.95)^x ( x is on top of the parentheses)

The decay rate is 5%.

Step-by-step explanation:

Let a substance is decaying at the rate of r% per hour from the initial value of P for t hours, then the final value of the substance is given by the function  

........... (1)

Comparing this equation with the original equation given as

............ (2) we get,

⇒

⇒ r = 5%.

Therefore, the decay rate is 5%. (Answer)

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
