Find the midpoint between (4,-1) and (3,2)

zepelin [54]

Midpoint has form of,

$M(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2})$

We can insert the data,

$M(\dfrac{4+3}{2},\dfrac{-1+2}{2})$

Which simplifies to,

$\boxed{M(3.5, 0.5)}$

Hope this helps.

Explicit equation for 5,10,20,40

eduard

Answer:

see explanation

Step-by-step explanation:

These are the terms of a geometric sequence with n th term

$a_{n}$ = a $(r)^{n-1}$

Where a is the first term and r the common ratio

r = $\frac{10}{5}$ = $\frac{20}{10}$ = $\frac{40}{20}$ = 2

and a = 5, hence explicit equation is

$a_{n}$ = 5 $(2)^{n-1}$
