Answer:
B) y=1/4x
Step-by-step explanation:
Because the slope of this graph is 1/4. You can find this because slope=rise/run. On the graph, it's always 1 upward and 4 rightwards, therefore, the slope is 1/4. Also, the y-intercept is 0 in this case.
You would take 1818÷33=55.09
55.09 is how many toothpicks it took for each step made
Then you would take 55.09×55=3029.95
You can make sure this is correct by taking 55.09×33=1817.97 which would actually be 1818 because you had to round it up
ANSWER
The explicit formula is :

EXPLANATION
The given sequence is
8,11,14,17,20,23,26,...
The first term is

The common difference is
d=11-8
d=3
The explicit formula is given by:

We substitute the values to get,

17^2 = 289
23^2 = 529
529 + 289 = 818
√818 = 28.6 inches
