The simple formula for the nth term of an arithmetic sequence is an = 5n + 15. What is the explicit formula corresponding to the
Nikitich [7]
Sequence will look like this:
Term 1: 20 --------- 20 + 5(0)
Term 2: 25 --------- 20 + 5(1)
Term 3: 30 --------- 20 + 5(2)
Term 4: 35 --------- 25 + 5(3)
ETC.

It cab noted that the numbers in the bracket (that is, 0, 1, 2, 3, 3, etc) = n-1

Then, the explicit formula will be;
an = 20 + 5(n-1).

The correct answer is D.

Noah is running a portion of a marathon at a constant speed of 6 mph. Complete the table to predict how long it would take him t
ycow [4]

Answer:

\begin{array}{cc}\text{Time}&\text{Distance}\\ \\1&6\\ \\\dfrac{1}{2}&3\\ \\1\dfrac{1}{3}&8\\ \\1\dfrac{1}{2}&9\\ \\9&54\\ \\4\dfrac{1}{2}&27\end{array}

Step-by-step explanation:

Noah's running speed = 6 mph.

Use formula D=v\cdot t, where

D is the distance,

v is the speed,

t is the time.

If t=1 hour, then D=6\cdot 1=6 miles.

If t=\dfrac{1}{2} hour, then D=6\cdot \dfrac{1}{2}=3 miles.

If t=1\dfrac{1}{3} hours, then D=6\cdot 1\dfrac{1}{3}=6\cdot \dfrac{4}{3}=8 miles.

If t=1\dfrac{1}{2} hours, then D=6\cdot 1\dfrac{1}{2}=6\cdot \dfrac{3}{2}=9 miles.

If t=9 hours, then D=6\cdot 9=54 miles.

If t=4\dfrac{1}{2} hours, then D=6\cdot 4\dfrac{1}{2}=6\cdot \dfrac{9}{2}=27 miles.

So, the table is

\begin{array}{cc}\text{Time}&\text{Distance}\\ \\1&6\\ \\\dfrac{1}{2}&3\\ \\1\dfrac{1}{3}&8\\ \\1\dfrac{1}{2}&9\\ \\9&54\\ \\4\dfrac{1}{2}&27\end{array}
