Answer:

d(x)=-750x^2-3750x-10500

Step-by-step explanation:

The manager of a department store uses the given function to model the monthly opening inventory of down comforters at the store, in dollars, where x represents the number of months from September.

d(x)=-750(x^2-5x-14)

To rewrite this hat reveals the store's opening inventory of down comforters in the month of September, multiply -750 on the bracket, we get

d(x)=-750x^2-3750x-10500

How much work is done lifting a 5 kg ball from a height of 2 m to a height of 6 m? (Use 10 m/s for the acceleration

Sedbober [7]

<h2>Explanation:</h2>

In physics, work is defined force that causes displacement. So this can be expressed by the following equation:

$W=Fs$

Where:

$F:Force \\ \\ s:Displacement$

The force can be found as:

$F=ma \\ \\ F=5(10)=50N$

And for the displacement:

$s=6-2=4m$

The force (weight) is down and the displacement is up, then the work must be negative. So:

$W=-(50)(4) \\ \\ \boxed{W=-200J}$
