Answer:15

Step-by-step explanation:

Given

Craftsman sell 10 Jewelry set for $500 each

For each additional set he will decrease the price by $ 25

Suppose he sells n set over 10 set

Earning $=\text{Price of each set}\times \text{no of set}$

Earning $=(500-25n)(10+n)$

$E=5000+500n-25n^2-250n$

differentiate to get the maximum value

$\frac{dE}{dn}=-50n+250$

Equate $\frac{dE}{dn}$ to get maximum value

$-50n+250=0$

$n=\frac{250}{50}$

$n=5$

Thus must sell 5 extra set to maximize its earnings.

A plane intersects a prism to form a cross section that is a polygon with five sides. The minimum number of sides that the polyg

antoniya [11.8K]

Answer:

Since the plane if cutting through the prism to make 5 sides, than the original shape needs to have less than 5.

A prism, is a 3D shape, so you can't have a 2 sided shape.

Now you have a choice of 3+or 4 sides.

A 3 sides shape is a triangle, which also can't be cut into a 5 sided prism, so the answer would need to be 4.

An observer (O) spots a plane (P) taking off from a local airport and flying at a 33° angle horizontal to her line of sight and

docker41 [41]

Answer:

the distance of the Bird (B) from the plane (P) is = 10779 ft

Step-by-step explanation:

From the given information:

a diagrammatic representation is attached below for better understanding and solution to the question.

From the diagram;

Let the Bird (B) be represent as A

The plane (P) be represented by B

The observer be represented by O

and the tower T be represented by C

we will see that:

$\overline {AB} \ \| \ \overline {OC}$

Also;

$\angle ABO = \angle BOC = 33^0$

AO = BC = 7000

Let consider the trigonometry of triangle BAO

tan θ = opposite/adjacent

tan 33° = 7000/x

0.6494 = 7000/x

x = 7000/0.6494

x = 10779.18

x = 10779 ft ( to the nearest whole number)

Thus; the distance of the Bird (B) from the plane (P) is = 10779 ft

In order for you to be able to solve this problem you have to first identify what the questions is asking. In this case it wants to know the approximation of what the semiannual income that Sarah will be able to draw.

To solve this you simply have to find the future value of her investment prior to retirement and use the as her investment amount upon retirement.

I hope it helps, Regards.
