Yes, the sequence is arithmetic as you keep going down 7 from each number. The rule or equation would be f(x)=42-7x.

You would do this so that you can find the specific number you want such as if you want to find what the 7th number in the sequence is you plug 7 in for x which would leave you with 42-7(7) or 42-49=-7

R varies directly as s. Find r when s=4 and k=2
lesya692 [45]
\bf \begin{array}{cccccclllll}
\textit{something}&&\textit{varies directly to}&&\textit{something else}\\ \quad \\
\textit{something}&=&{{ \textit{some value}}}&\cdot &\textit{something else}\\ \quad \\
y&=&{{ k}}&\cdot&x
\\
&&  y={{ k }}x
\end{array}\\\\
-------------------------------\\\\
thus\implies r=ks\qquad 
\begin{cases}
k=2\\

variation\\
s=4

What is the distance between the points (1, -4) and (1, 0)
tino4ka555 [31]

For this case we have that the distance between two points is given by:


d = \sqrt{(y2-y1)^2+(x2-x1)^2}

Given the points:


(x1, y1) = (1, -4)(x2, y2) = (1,0)

We substitute in the formula:


d = \sqrt{(0 - (- 4)) ^ 2 + (1-1) ^ 2}

d = \sqrt{(4 ^ 2 + 0 ^ 2)}

d=\sqrt{16}

d = 4

So, the distance is d = 4

Answer:


d = 4
