7 0

Answer:

39062.5

Step-by-step explanation:

-2+-10+-50+-250

-10/2=-250/-50 = 5

sum of the geometric sequence

Sₙ = arⁿ⁻¹ /r-1    a=-2,  r = 5

S₈ = -2(5)⁸⁻¹/(5-1) = 2(5⁷)/4 = 2(78125)/4= 78125/2= 39062.5

S₈=39062.5

What is the scale factor from L to S?
MariettaO [177]

Answer: While I don’t have the picture to actually know the answer I will explain how to get it.

Step-by-step explanation:

1. If the shapes are on a grid count the amount of grid squares that are located between each end point of the shape. If it’s not on a grid use a ruler to measure the side lengths. You will need to find out the side amounts for both shapes L and S.

2. From there if the L shape is SMALLER than the S shape, then take the S shape’s sides and divide it by the L shape’s sides, and whatever number you get from each of your division problems will be your scale factor. BUT If the L shape is BIGGER than the S shape then easiest way to find out your scale factor is to take the last scale factor you got and convert it into a fraction. For example, if you got 3 then it would be 1/3. Hope this helped!
