Question

║×i could really use some help the answers are multiple choice as well× ║

the table shows the weight of an animal, in kilograms, over a period of several months, with a question mark for the missing weight.

month: 1, 4, 7, 10, 13.
weight (kg): 40, ?, 62.5, 78, 97.5.

what statement is true?


a) the situation is modeled by a linear function with equal differences of 15.5
b) the situation is modeled by a linear function with differences of 19.5.
c) the situation is modeled by an exponential function with equal factors of about 0.25.
d) the situation is modeled by an exponential function with equal factors of about 1.25.

Answer 1

The answer would be D. The weight is growing exponentially by a factor of around 1.25 each time.

40 x 1.25 = 50

50 x 1.25 = 62.5

62.5 x 1.25 = 78

78 x 1.25 = 97.5
