the answer is 6/13 because 12/26 reduces so the answer is 6/13
I’ll teach you how to solve 3x-5=-18
—————————————-
3x-5=-18
Move constant to the right-hand side and change its sign:
3x=-18+5
Calculate the sum:
3x=-13
Divide both sides of the equation by 3:
X=-13/3
Your Answer Is x=-13/3
Plz mark me as brainliest if this helped :)
First, we inspect what type of sequence is the order of the coordinates:
a2 = 1
a3 = 2
a4 = 4
Getting the difference,
a3 - a2 = 1
a4 - a3 = 2
The differences are not equal; hence, the sequence is not arithmetic.
Getting the ratio:
a3/a2 = 2
a4/a3 = 2
The common ratio is 2. Using the general form for a geometric series:
an = a1 r^(n-1)
If n = 2
1 = a1 (2)^(2-1)
a1 = 1/2
So,
an = (1/2) (2)^(n-1)
The answer is the first option.
To solve this we are going to use the formula fro the force applied to a spring:

where

is the spring constant

is the extension
Since we know the

, we can replace that in our formula and solve for

:


where

is the acceleration

is the spring constant

is the extension

is the mass
We know for our problem that

,

, and

. So lets replace those values in our formula to find

:



We can conclude that the acceleration of the block when s=0.4m is

.
