Mitch is making a target for the beanbag toss at his school's fall fun-run and carnival. the target is a short round basket divided evenly into 4 sections. the player wins a prize for each section the beanbag lands in. there is 1 section that wins the player a rubber ball. there are 3 sections that win the player a teddy bear. what fraction of the target wins the player a teddy bear?

Answer:

24 trillion miles. The nearest-known exoplanet is a small, probably rocky planet orbiting Proxima Centauri – the next star over from Earth. A little more than four light-years away, or 24 trillion miles.

The number of miles in 4.25 light-years will be 24.986 × 10¹² miles.

Conversion means to convert the same thing into different units.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

The nearest-known exoplanet from the earth is 4.25 light-years away.

We know that 1 lightyear = 5.879 × 10¹² miles.

Then the number of miles in 4.25 light-years will be

⇒ 4.25 light-years

⇒ 4.25 × 5.879 × 10¹² miles

⇒ 24.986 × 10¹² miles

The number of miles in 4.25 light-years will be 24.986 × 10¹² miles.

The velocity of a particle when it moves on a straight line along the x-axis will be V= 42 m/s

Velocity is defined as the ratio of the distance moved by the object in a particular time. The velocity is a vector quantity so it needs both the magnitude and the direction.  

Here we have a displacement function:-

F(t)=3t⁴-5t³+6t-7

So to find out the velocity we will differentiate the above equation with respect to t.

d(F(t)/dt=12t³-15t²+6

V=12t³-15t²+6

Put the value of t=2 seconds

V=12x(2x2x2)-15x(2x2)+6

V=42 meters per second

Hence the velocity of a particle when it moves on a straight line along the x-axis will be V= 42 m/s

The greatest number of pieces will be 12 where each piece will have a different length and the length of each piece is a whole number, in inches and the remaining piece length will be 12 in(90 - 78).

It is defined as the systematic way of representing the data that follows a certain rule of arithmetic.

The total length of the wood = 90 in

We have to cut it into the greatest number of pieces, where each piece will have a different length and the length of each piece is a whole number, in inches.

We can cut it like:

1 in, 2 in, 3 in, 4 in, and so on

The above shows the arithmetic sequence,

The sum of the n natural number is given by:

[tex]\rm S_n = \dfrac{n(n+1)}{2}[/tex]

[tex]\rm 90 = \dfrac{n(n+1)}{2}[/tex]

After solving, we will get a quadratic equation:

n² + n -180 = 0

After solving, we will get:

n = 12.92 and n = -13.92(term can not be negative)

n = 12 (taking whole number)

Thus, the greatest number of pieces will be 12 where each piece will have a different length and the length of each piece is a whole number, in inches and the remaining piece length will be 12 in(90 - 78).

Step-by-step explanation:

the extreme values (minimum, maximum) of a function are the zero points of the first derivation of the function.

so,

f'(x) = 2x + b

and then

2x + b = 0

we know, x = 20 for the minimum

2×20 + b = 0

40 + b = 0

b = -40

therefore, the actual function is

f(x) = x² - 40x + 164

the target format is

f(x) = (x - h)² + k = x² - 2hx + h² + k

so,

-40x = -2hx

-40 = -2h

h = 20

and

h² + k = 164

20² + k = 164

400 + k = 164

First degree equation is a mathematical expression and sentence, which is defined by having only one unknown. Its representation is given by: ax+b=0.

— To solve this expression, let's eliminate these square root symbols:

√-5p = √24-p

-5p = 24 - p

— Move the p term before the positive sign equality, thus also shifting the 24th term:

-5p = 24 - p

-5p + p = 24

-4p = 24

The first term is,  8x2  its coefficient is  8 .

The middle term is,  -40x  its coefficient is  -40 .

The last term, "the constant", is  -5

Step-1 : Multiply the coefficient of the first term by the constant   8 • -5 = -40

Step-2 : Find two factors of  -40  whose sum equals the coefficient of the middle term, which is   -40 .

     -40    +    1    =    -39

     -20    +    2    =    -18

Parabola, Finding the Vertex:

3.1      Find the Vertex of   y = 8x2-40x-5

Parabolas have a highest or a lowest point called the Vertex .   Our parabola opens up and accordingly has a lowest point (AKA absolute minimum) .   We know this even before plotting  "y"  because the coefficient of the first term, 8 , is positive (greater than zero).

Each parabola has a vertical line of symmetry that passes through its vertex. Because of this symmetry, the line of symmetry would, for example, pass through the midpoint of the two  x -intercepts (roots or solutions) of the parabola. That is, if the parabola has indeed two real solutions.

Parabolas can model many real life situations, such as the height above ground, of an object thrown upward, after some period of time. The vertex of the parabola can provide us with information, such as the maximum height that object, thrown upwards, can reach. For this reason we want to be able to find the coordinates of the vertex.

For any parabola,Ax2+Bx+C ,the  x -coordinate of the vertex is given by  -B/(2A) . In our case the  x  coordinate is   2.5000  

Plugging into the parabola formula   2.5000  for  x  we can calculate the  y -coordinate :

 y = 8.0 * 2.50 * 2.50 - 40.0 * 2.50 - 5.0

or   y = -55.000

Parabola, Graphing Vertex and X-Intercepts :

Root plot for :  y = 8x2-40x-5

Axis of Symmetry (dashed)  {x}={ 2.50}

Vertex at  {x,y} = { 2.50,-55.00}

x -Intercepts (Roots) :

Root 1 at  {x,y} = {-0.12, 0.00}

Root 2 at  {x,y} = { 5.12, 0.00}

Solve Quadratic Equation by Completing The Square

3.2     Solving   8x2-40x-5 = 0 by Completing The Square .

Divide both sides of the equation by  8  to have 1 as the coefficient of the first term :

  x2-5x-(5/8) = 0

Add  5/8  to both side of the equation :

  x2-5x = 5/8

Now the clever bit: Take the coefficient of  x , which is  5 , divide by two, giving  5/2 , and finally square it giving  25/4

Add  25/4  to both sides of the equation :

 On the right hand side we have :

  5/8  +  25/4   The common denominator of the two fractions is  8   Adding  (5/8)+(50/8)  gives  55/8

 So adding to both sides we finally get :

  x2-5x+(25/4) = 55/8

Adding  25/4  has completed the left hand side into a perfect square :

  x2-5x+(25/4)  =

  (x-(5/2)) • (x-(5/2))  =

 (x-(5/2))2

Things which are equal to the same thing are also equal to one another. Since

  x2-5x+(25/4) = 55/8 and

  x2-5x+(25/4) = (x-(5/2))2

then, according to the law of transitivity,

  (x-(5/2))2 = 55/8

We'll refer to this Equation as  Eq. #3.2.1  

The Square Root Principle says that When two things are equal, their square roots are equal.

Note that the square root of

  (x-(5/2))2   is

  (x-(5/2))2/2 =

 (x-(5/2))1 =

  x-(5/2)

Now, applying the Square Root Principle to  Eq. #3.2.1  we get:

  x-(5/2) = √ 55/8

Add  5/2  to both sides to obtain:

  x = 5/2 + √ 55/8

Since a square root has two values, one positive and the other negative

  x2 - 5x - (5/8) = 0

  has two solutions:

 x = 5/2 + √ 55/8

  or

 x = 5/2 - √ 55/8

Note that  √ 55/8 can be written as

 √ 55  / √ 8

Solve Quadratic Equation using the Quadratic Formula

3.3     Solving    8x2-40x-5 = 0 by the Quadratic Formula .

According to the Quadratic Formula,  x  , the solution for   Ax2+Bx+C  = 0  , where  A, B  and  C  are numbers, often called coefficients, is given by :

           - B  ±  √ B2-4AC

 x =   ————————

                     2A

 In our case,  A   =     8

                     B   =   -40

                     C   =   -5

Accordingly,  B2  -  4AC   =

                    1600 - (-160) =

                    1760

Applying the quadratic formula :

              40 ± √ 1760

  x  =    ——————

                     16

Can  √ 1760 be simplified ?

Yes!   The prime factorization of  1760   is

  2•2•2•2•2•5•11

To be able to remove something from under the radical, there have to be  2  instances of it (because we are taking a square i.e. second root).

√ 1760   =  √ 2•2•2•2•2•5•11   =2•2•√ 110   =

               ±  4 • √ 110

 √ 110   , rounded to 4 decimal digits, is  10.4881

So now we are looking at:

          x  =  ( 40 ± 4 •  10.488 ) / 16

Two real solutions:

x =(40+√1760)/16=5/2+1/4√ 110 = 5.122

or:

x =(40-√1760)/16=5/2-1/4√ 110 = -0.122

Answer:

B

Answer:  Choice A

(-2, -2)

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

Explanation:

I'll use the substitution method to solve this system.

Replace y in the first equation with -x-4. This is because y = -x-4 is mentioned in the second equation.

So,

3x + 2y = -10

3x + 2( y ) = -10

3x + 2( -x-4 ) = -10 .... substitution

3x - 2x - 8 = -10

x - 8 = -10

x = -10+8

x = -2

Then use this to find y

y = -x-4

y = -(x) - 4

y = -(-2) - 4

y = 2 - 4

y = -2

We have x = -2 and y = -2 pair up together

They form the ordered pair solution (x, y) = (-2, -2)

This shows why Choice A is the answer.
