A company's revenue from selling x units of an item is given as R = 1000 x − 3 x 2 . If sales are increasing at the rate of 25 units per day, how rapidly is revenue increasing (in dollars per day) when 120 units have been sold?

Revenue is increasing at a rate of $280 per day.

Step-by-step explanation:

Revenue function is given as R = 1000x - 3x^2

The rate at which revenue is increasing is obtained by differentiating R with respect to x

R = 1000x - 3x^2

dR/dx = 1000 - 6x

when x = 120 units

dR/dx = 1000 - 6(120) = 1000 - 720 = 280 dollars per day

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.
