There are 50 apple trees in an orchard. Each tree produces 800 apples. For each additional tree planted in the orchard, the outp

Mariana [72]

Answer:

<em> 15</em>
<em> 42,250</em>

Step-by-step explanation:

The given function is,

$P=40000+300x-10x^2$

where,

P = the total production of apples,

x = the number of trees added.

As the quadratic function has a negative leading coefficient, so it will open downward and at the vertex the value of function is maximum.

The vertex will be at $\left(-\dfrac{b}{2a},-f\left(\dfrac{b}{2a}\right )\right)$

The value of the function will be maximum at,

$x=-\dfrac{b}{2a}$

Putting the values,

$x=-\dfrac{300}{2\times (-10)}=\dfrac{300}{2\times 10}=\dfrac{300}{20}=15$

So at x=15 or for 15 number of trees the production will be ,maximum.

Putting x=15 in f(x) will yield the maximum production of apples.

$P=40000+300(15)-10(15)^2=42,250$

What percent of 33 is 22

serious [3.7K]

Wait so are you asking what 22% of 33 is?
if so you cross multiply so
33 = 100%
? = 22%
then you times 33 x 22 = 726
then you divide 726 by 100 = 7.26
so 22% of 33 is 7.26

Twenty five percent of this square is shaded what percent of the square is not shaded

Dominik [7]

Answer:

75%

Step-by-step explanation:

If 25 percent of a square is shaded, that means that the rest of the square is not shaded. We want an answer that we can add to 25 to get 100. So this means that 75% of the square is not shaded.
