Answer: B
Work:
Since the general formula of an arithmetic sequence is f(n) = (the first term) + (common difference)*(n-1), you just plug in what was given to you in the problem to that equation. The first term is -20 and the common difference is +15 since the the increase from one term to the next is 15. Doing so produces the equation f(n) = -20 + 15(n-1), which is choice B.
Answer:
5 inches by
inches
Step-by-step explanation:
According to the scale given, to convert "feet" to "inches", we have to multiply each feet by 1/4th. The drawing would be a "smaller" version of the original. That would be in inches.
So, 20 ft would be:
20 * 1/4 = 20/4 = 5 inches
and
27 feet would be:
27 * 1/4 = 27/4 inches
The dimension would thus be:
5 inches by
inches
