Answer:
Neither
Step-by-step explanation:
This is a linear function as opposed to an exponential function as there are no x terms in higher powers.
3 is incorrect because 14.7 + 3 = 17.7
The answer of 15 - 14.7 = 0.3
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:
one possible number of bonus is 9.
Step-by-step explanation:
Let, the number of $250 bonus = x and number of $750 bonus = y.
We have that bonuses are given in amounts $250 and $750.
Since, the total bonus is $3000.
So, we get,
250x + 750y = 3000.
As, there is atleast one $250 bonus and atleast one $750 bonus.
Let, the minimum number of bonus of $750 be 1 i.e. y = 1.
Substitute in the equation gives,
250x + 750 × 1 = 3000
i.e. 250x = 3000 - 750
i.e. 250x = 2250
i.e. x = 9
Thus, the maximum number of $250 bonus are 9.
Hence, one possible number of bonus is 9.
They all involve descriptive statistics.
