Answer:

208.333

Step-by-step explanation:

A quadratic model for a certain stock on Wall Street is given by :

[tex]P=-3d^2+50d[/tex] ...(1)

(a) We need to find the maximum price per share of the stock. For maximum value, put :

[tex]\dfrac{dP}{dd}=0[/tex]

[tex]\dfrac{d(-3d^2+50d)}{dd}=0\\\\-6d+50=0\\\\d=\dfrac{50}{6}\\\\d=8.34[/tex]

price per share of the stock is maximum when the value of d = 8.34. Put the value of d in equation (1).

[tex]P=-3(8.34)^2+50(8.34)\\\\P=208.333[/tex]

So, the maximum price per share of the stock is 208.333.

Answer:

In mathematics, genuinely or simplification is reducing the expression/fraction/hassle in a less complicated form. It makes the problem smooth with calculations and fixing.

Associated with "simplification" troubles are some "solving" troubles. just as a few expressions include parentheticals or even nested grouping symbols, so additionally do some equations. The simplification manner is identical, whether we're running with expressions (and consequently handiest simplifying) or equations (so we are also solving).

Step-by-step explanation:

I am going to pose c as the largest side in a random triangle

If so then remember that, by the triangle inequality, a + b > c. Let's start from there...

Statement:                         |                                  Reasoning:

1. a + b > c                                                             1. Triangle Inequality

2. a + b + c > c + c (adding c on both sides),      2. Algebra + Def. Of Perimeter

   a + b + c > 2c (simplified)

   Perimeter > 2c (definition of perimeter)

   c < 1/2 * Perimeter

The prove of statement ''in any triangle the length of a side is less than the half of the perimeter'' is shown.

What is Perimeter?

The sum of all sides of a quadrilateral is called a perimeter.

Given that;

The statement is,

''In any triangle the length of a side is less than the half of the perimeter''.

Now,

Let sides of triangles are a, b and c.

The triangle inequality is;

a + b > c

Add both side by c;

a + b + c > c + c

a + b + c > 2c   .... (i)

Since, Perimeter of a triangle with sides a, b and c is;

Perimeter (P) = a + b + c

Substitute value of perimeter in equation (i), we get;

a + b + c > 2c

P > 2c

c < P/2

Thus, In any triangle the length of a side is less than the half of the perimeter.

Here we are given with a triangle with smaller triangles formed due to the altitude on AC. Given:

We have to find the value for sin [tex] \theta[/tex]

So, Let's start solving....

In ∆ADB and ∆ABC,

So, ∆ADB ~ ∆ABC (By AA similarity)

The corresponding sides will be:

[tex] \sf{ \dfrac{AD}{AB} = \dfrac{AB}{AC} }[/tex]

We know the value of AB and to find AC, we can use Pythagoras theoram that is:

AC = √6² + 8²

AC = 10

Coming back to the relation,

[tex] \sf{ \dfrac{AD}{6} = \dfrac{6}{10} }[/tex]

[tex] \sf{AD = \dfrac{6 \times 6}{10} = 3.6}[/tex]

In ∆ADB, we have to find sin [tex] \theta[/tex] which is given by perpendicular/base:

Answer:

He spent on fruit after 5 months is $110.

In 15 months he spent $280.

Step-by-step explanation:

Fixed pay for membership is $25

And enrollment fee is $17 for each month.

The equation represents this situation is

y= 17 x + 25

He is going to stop receiving fruits once he spent $280.

Now, to find how much he spent on fruit after 5 months is plugin x as 5 into

y=17x+25 for x

y=17(5)+25

y=85+25

y=110 dollars

Now, to find how many months until $280 is to plug in y as 280 then solve the equation for x.

280 = 17 x+25

Subtract both sides 25

255 =17 x

Divide both sides by 17

x= 15 months

Answer:

Integers

Step-by-step explanation:

The correct option to choose is the integers option. Integers are simply whole numbers.

Thus-18/6 = -3

The term -3 is a whole number

So the term to choose is the integers option

The smallest set of real numbers that contains the value -18 /6 is an integer.

The smallest set of the real number that contains the value -18/6 can be determined after we have simplified the expression -18/6.

To simply the given expression, we will divide both the numerator and the denominator by 6, by doing so, we have:

= -3

Now, the smallest set of the real number is = -3 which is an integer

This is because an integer is a whole number that is not a fraction and can be negative or positive.

The reason why it is not a natural number is because of the negative sign, since we know that natural numbers are numbers with positive signs only.

Answer: Second company (in the table), aka #1 toys, produces at a slower rate

============================================================

Explanation:

The equation y = 123x is in the form y = mx+b with m = 123 as the slope. The slope is the rate of change telling us how many toys per minute are produced. In this case, 123 toys per minute is the rate for the first company.

----------

We'll need the slope of the other function. So we need to pick two rows from the table and use the slope formula. I'll pick the first two rows.

m = (y2-y1)/(x2-x1)

m = (1320-600)/(11-5)

m = 720/6

m = 120

The second company produces at a rate of 120 toys per minute. This is the smaller rate, so this company produces at a slower speed.

Step-by-step explanation:

given the perimeter is

64ft

the length l= 3w

we know that the perimeter of a rectangle is given as

P=2l+2W

but L=3w

64=2(3w)+2w

64=6w+2w

64=8w

divide both sides by 8 we have

w=64/8

w=8ft

also

let the lenght of the rectangle be l

side of hexagon=l-4

perimeter of hexagon

P=5(l-4)

P=5l-20

width of rectangle w=l-2

perimeter of rectangle= 2l+2w

but w=l-2

5l-20= 2l+2(l-2)

5l-20=2l+2l-4

5l-20=4l-4

5l-4l=-4+20

l=16ft

perimeter of hexagon

P=5(l-4)

put l=16

perimeter of hexagon

P=5(16-4)

p=5(12)

P=60ft
