Answer:
The growth "rate" (r) is determined as b = 1 + r.
Step-by-step explanation:
A growth factor is the factor by which a quantity multiplies itself over time. When trying to find the growth rate, you have to remember that the original exponential formula was y = ab^x. You will notice that in these new growth and decay functions, the b value (growth factor) has been replaced either by (1 + r) or by (1 - r). The growth "rate" (r) is determined as b = 1 + r.
Please mark me the brainliest!?!
I think its equal im not exactly sure so dont blame me if u get it worng :(
Answer:
20 km/h
Step-by-step explanation:
Zoey rode a total of 120 km (there and back) in a total time of 6 hours (=2.5+3.5). Her average speed is given by ...
speed = distance/time = (120 km)/(6 h) = 20 km/h
