In the function f(t)=50(1.2)^t, what is the rate of change
a. 20%decay
b. 2% growth
c.2%decay
d.20%growth

d.20%growth

Step-by-step explanation:

The given function is similar to the exponential growth function , where A is the initial amount , r is the rate of growth and t is the time period.

In the given function A=50

Hence, in the given F(t), the rate of change = 20%growth.

answer: it's a

step-by-step explanation:

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
