Well if hes gonna add .25 cents every 6th month then i think you would have to pick D because it shows the starting pay (5.50) then adds the .25 for every 6th month. Hope i helped :)
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

.
Answer:
(-1,-4)
Step-by-step explanation:
Using the rule of when we rotate 90 degrees clockwise
(x,y) goes to (y,-x). We plug it in.
(4,-1) goes to (-1,-4).
Answer:
-4
Step-by-step explanation:
(-7)(-1) = -8
-8+4 = -4
