Answer:

The function which models the situation is as The number of oak trees increase after n year = 12 ×  (1+\frac{25}{100})^{n}

Step-by-step explanation:

Given as :

The number of oak trees planted in park = 12

The rate at which number of tree increase each year= 25%

Now,

The number of oak trees increase after n year = Present numbers of tree × (1+\frac{Rate}{100})^{n}

Or,

The number of oak trees increase after n year = 12 × (1+\frac{25}{100})^{n}

Hence The function which models the situation is as The number of oak trees increase after n year = 12 × (1+\frac{25}{100})^{n}  Answer

From the diagram, we know that it is an angle that adds up to 360

So

x+4x+2x+10+5x+50=360


Gather like terms

12x+60=360

Move sixty to the other side as a negative number

12x=300

Divide both sirs by twelve

x is equal to 25

AOB is 2x+10

Sub x in 2*25+10

AOB is 60

BOC is 5x+50

5*25+50, which is 175

BOD is x+2x+10

Which is 3x+10

Sub x

3*25+10 which is 85

A company sells widgets. The amount of profit, y, made by the company, is related to the selling price of each widget, x, by the
Anastasy [175]

Answer: 19.4

Step-by-step explanation:

Given

Profit is given in terms of the selling price

y=-5x^2+194x-900

to get the maximum price, differentiate y w.r.t x

\frac{\mathrm{d} y}{\mathrm{d} x}=-5\times 2x+194

Put  \frac{\mathrm{d} y}{\mathrm{d} x}=0 to get maximum value

10x=194\\x=19.4

Thus, the company must sell it at 19.4
