Riko wants to find the distance between the points (−2, −3) and (2, −5). His work is shown. The distance is 8 units. Riko correct? Explain why or why not.

incorrect

Step-by-step explanation:

The calculation he has done only calculates the distance between the y- coordinates of the points.

Calculate the distance d using the distance formula.

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (- 2, - 3) and (x₂, y₂ ) = (2, - 5)

d =

   =

   =

   = = = 2 ← exact distance

step-by-step explanation:

mean or average is 40.6

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~
