By my calculations and understanding into this problem I have figured out the answer to this thing and it is very simple and easy enough to actually say it so I can type it out instead because I can’t say anything on this thing even though I’m doing a voice record and I don’t even know how my grandma is doing right now so I’m just blah bling around is it random words of mine but honestly I would love to explain and tell you the answer but I do not know how to type it out so I’m just going to say it like I just said two seconds ago but I didn’t really say it again I just typed it I don’t know I keep getting confused with that but anyways the answer is very easy

10. What is the distance between (8,7) and (3,-5)?

Anarel [89]

Answer:

distance between points=13 units

Step-by-step explanation:

distance between points= $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

put $(x_1,x_2)$ =(8,7) and $(y_1,y_2)$ =(3,-5)

distance between points= $\sqrt{(3-8)^2+(-5-7)^2}$

distance between points= $\sqrt{(-5)^2+(-12)^2}$

distance between points= $\sqrt{25+144}$

distance between points= $\sqrt{169}$

distance between points=13 units answer

2,-10,50,-250,.. Geometric sequence

nikklg [1K]

This question is incomplete, here is the complete question

What is the recursive formula for this geometric sequence 2, -10, 50, -250, .... ?

The recursive formula for this geometric sequence is:

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

Step-by-step explanation:

To find the recursive formula for a geometric sequence:

Determine if the sequence is geometric (Do you multiply, or divide, the same amount from one term to the next?)
Find the common ratio. (The number you multiply or divide.)
Create a recursive formula by stating the first term, and then stating the formula to be the common ratio times the previous term.

The recursive formula is:

$a_{1}$ = first term; $a_{n}$ = r • $a_{n-1}$ , where

$a_{1}$ is the first term in the sequence
$a_{n-1}$ is the term before the nth term
r is the common ratio

∵ The geometric sequence is 2 , -10 , 50 , -250

∴ $a_{1}$ = 2

- To find r divide the 2nd term by the first term

∵ $r=\frac{a_{2}}{a_{1}}$

∴ $r=\frac{-10}{2}=-5$

- Substitute the values of $a_{1}$ and r in the formula above

∴ $a_{1}$ = 2; $a_{n}$ = (-5) • $a_{n-1}$

The recursive formula for this geometric sequence is:

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