Bamboo plants grow rapidly. a bamboo plant is 130 inches tall. tomorrow it will be 143 inches tall, the next day it will be 156 inches tall, and on the next day it will be 169 inches tall. write an explicit formula to represent the height of the bamboo plant as an arithmetic sequence. how tall will the plant be in 13 days?
a. a(n) = 130 + 13n; 286 inches
b. a(n) = 130 + (n-1)13; 286 inches
c. a(n) = 130 + (n-1)13; 299 inches
d. a(n) = 130 + 13n; 299 inches <

Your choice of answer D is correct.

When the number of days is zero, the height is 130 inches. This eliminates choices B and C. Evaluating the expression for n=13 gives

... 130 + 13×13 = 130 + 169 = 299 . . . . . corresponding to answer D.

step-by-step explanation:

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
