Sorry my laptop camera sucks. Let me know if you can't see it :)

the height y (in feet) of a ball thrown by a child is
[tex]y = \frac{1}{16} {x}^{2} + 4x + 3[/tex]
where x is the horizontal distance in feet from the point at which the ball is thrown

a).how high is the ball when it leaves the child's hand

b).what is the maximum high of the ball

c).how far from the child does the ball strike the ground

Answers

a. The height of the ball when it leaves the child's hand is 3 feet, as [tex]\(x = 0.[/tex]

b. The maximum height of the ball is 195 feet, calculated by finding the vertex of the parabolic function.

c. The distance from the child where the ball strikes the ground is approximately 47.24 feet, using the quadratic formula.

Given the equation representing the height y of a ball as a function of the horizontal distance x :

[tex]\[y = \frac{1}{16} x^2 + 4x + 3\][/tex]

Part (a): Height of the ball when it leaves the child's hand

The ball leaves the child's hand when x = 0.

Substituting x = 0 into the equation:

[tex]\[y = \frac{1}{16} \cdot 0^2 + 4 \cdot 0 + 3 = 3\][/tex]  

Thus, the height of the ball when it leaves the child's hand is 3 feet.

Part (b): Maximum height of the ball

The given function represents a parabola, and since [tex]\(a = \frac{1}{16}[/tex] is positive, it opens upward.

To find the maximum height, we need the x-coordinate of the vertex, which can be found using:

[tex]\[x = -\frac{b}{2a} = -\frac{4}{2 \cdot \frac{1}{16}} = -\frac{4}{\frac{1}{8}} = -32\][/tex]

However, the correct derivation is:

[tex]\[x = -\frac{4}{2 \cdot \frac{1}{16}} = -\frac{4}{\frac{1}{8}} = -32 \cdot 8 = -64\][/tex]

But the correct value for x should be:

[tex]\[x = -\frac{4}{2 \times \frac{1}{16}} = -4 \times 8 = -32[/tex]

Considering this, let's correct the previous explanation and use the correct approach:

1. Find the x-coordinate of the vertex:

[tex]\[x = -\frac{4}{2 \times \frac{1}{16}} = -8 = 32\][/tex]

With the x-coordinate of the vertex, find the maximum height (the y-coordinate of the vertex):

[tex]\[y = \frac{1}{16} \cdot 32^2 + 4 \cdot 32 + 3 = \frac{1024}{16} + 128 + 3 = 64 + 128 + 3 = 195\][/tex]

Thus, the maximum height is 195 feet

Part (c): How far from the child does the ball strike the ground?

To find out when the ball strikes the ground, we need to set \(y = 0\) and solve for \(x\):

[tex]\[0 = \frac{1}{16} x^2 + 4x + 3\][/tex]

Using the quadratic formula, where[tex]\(a = \frac{1}{16}\), \(b = 4\), and \(c = 3\):[/tex]

[tex]\[x = \frac{-4 \pm \sqrt{4^2 - 4 \cdot \frac{1}{16} \cdot 3}}{2 \cdot \frac{1}{16}} = \frac{-4 \pm \sqrt{16 - \frac{12}{16}}}{\frac{1}{8}} \][/tex]

To find the x-coordinates where the ball strikes the ground, you can set (y = 0) and solve for (x):

[tex]\[0 = \frac{1}{16} x^2 + 4x + 3\][/tex]

Using the quadratic formula, where [tex]\(a = \frac{1}{16}\), \(b = 4\), and \(c = 3\) :[/tex]

[tex]\[x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}\][/tex]

Substitute the given values of a ,b , and c into the quadratic formula:

Calculate [tex]\(b^2 - 4ac\) :[/tex]

  - [tex]\(b^2 = 4^2 = 16\),[/tex]

  - [tex]\(4 \cdot \frac{1}{16} \cdot 3 = \frac{12}{16} = \frac{3}{4}\),[/tex]

  - So [tex]\(b^2 - 4ac = 16 - \frac{3}{4} = \frac{64}{4} - \frac{3}{4} = \frac{61}{4}\).[/tex]

Calculate the roots :

  - The value for [tex]\(a\) is \(\frac{1}{16}\), so \(2a = \frac{1}{8}\),[/tex]

  - Now we can find \(x\):

   [tex]\[ x = \frac{-4 \pm \sqrt{16 - \frac{3}{4}}}{\frac{1}{8}} = \frac{-4 \pm \sqrt{61/4}}{1/8} = -32 \pm 2 \sqrt{61}. \][/tex]

Simplifying the roots :

  - The roots for x are:

   [tex]\[ x_1 = -32 + 2 \sqrt{61}, \, x_2 = -32 - 2 \sqrt{61}. \][/tex]

However, we consider only the positive root, as it represents the distance from the point where the ball is thrown to where it lands.

Thus, the value of [tex]\(x_1\)[/tex] is:

[tex]\[x = -32 + 2 \sqrt{61} \approx -32 + 15.6 = -16 + 16 \cdot \sqrt{61} \approx 47.24\][/tex]

Thus, the correct answer with [tex]\(x\approx 47.24\).[/tex]

The complete question is : The height y (in feet) of a ball thrown by a child is

[tex]y = (1)/(16) {x}^{(2)}+ 4x + 3[/tex]

where x is the horizontal distance in feet from the point at which the ball is thrown

a).how high is the ball when it leaves the child's hand ?

b).what is the maximum high of the ball ?

c).how far from the child does the ball strike the ground ?

The answer provides step-by-step explanations for finding the initial height, maximum height, and horizontal distance at which the ball strikes the ground, given the equation of the ball's height as a function of the horizontal distance.

To find the height of the ball when it leaves the child's hand (a), we need to determine the value of y when x is 0. Substituting x = 0 into the equation, we get:

y = -1/14(0)² + 2(0) + 3

y = 3 feet

Therefore, the ball is 3 feet high when it leaves the child's hand.

let's find the maximum height of the ball (b), we need to find the vertex of the quadratic equation. The vertex can be found using the formula x = -b/2a, where a, b, and c are the coefficients of the quadratic equation. In this case, a = -1/14, b = 2, and c = 3. Substituting these values into the formula, we get:

x = -2 / (2 * (-1/14))

x = 7 feet

Substituting x = 7 into the equation, we can find the maximum height:

y = -1/14(7)² + 2(7) + 3

y = 10.5 feet

Therefore, the maximum height of the ball is 10.5 feet.

let's find how far from the child the ball strikes the ground (c), we need to find the x-coordinate when y = 0. Setting y = 0 in the equation, we get:

0 = -1/14x² + 2x + 3

Solving this quadratic equation,

hence we find two possible values for x: x = -7 and x = 28. Since the ball is thrown in a positive direction, the ball strikes the ground 28 feet away from the child.

Section 208 of nassau veterans Memorial Coliseum has 17 rows. The first row has 13 seats in it. If you add two seats to the previous row for each row in the section, how many seats are in row 15? How many seats total are there in the section?

Answers

Row 15 has 41 seats, and the entire section has 493 seats.

We can write the explicit formula for an arithmetic sequence to represent this, since we add 2 each time:

13+2(n-1)

Using 15 for n,
13+2(15-1) = 13+2(14) = 13+28 = 41

To find the total number of seats, we evaluate the sum
[tex]\Sigma_{n=1}^{17} 13+2(n-1)[/tex]

Using technology to evaluate this sum, it is 493.

Draw a line from K to M. If you draw any angle whose vertex is on the upper side of KM, you get two angles that add to 180o. One of the angles is 104x + 1.

But ...

What do you do about the arc? It is 211o - 1? That value = the central angle. A central angle is the angle going from K to the center of the circle to M. 1/2 that amount is the angle going to anywhere on the arc of the circle. So that is 1/2 of 211 - 1 = 105.5x - 1/2

These two angles when added together = 180o

105.5x - 1/2 +  104x + 1 = 180o         Collect like terms on the left
209.5x  + 1/2  =  180                          Subtract 1/2 from both sides

The correct answer is:  [C]:  " 37, 680 mm³ " .
________________________________________________________

Explanation:
________________________________________________________

The formula for the volume, "V" , of a cylinder is:

                →   V  =   [tex] \pi [/tex]  *  r²  *  h  ;  

                           → in which "r = length of radius" ;  "h = height" ;             ________________________________________________________

     {Note that the formula for the volume, "V" , of a cylinder is:
     
                                " Base area * height " .
________________________________________________________

         →  Specifically, for a cylinder, the "Base area" is the area of a "circle", because the base is a circle;  

          →  and the formula for the "area of a circle = [tex] \pi [/tex] * r² " ;

          →  in which "r = length of the radius" . 

As such, the formula for the volume, "V" ,  of a cylinder is:
______________________________________________________
       →   Volume  =  (Base area) * (height)

                             =  ( [tex] \pi [/tex] r² ) * h  ;
______________________________________________________

       →   V  =  [tex] \pi [/tex]  r²  h  


                 in which:  "V = volume  {in "cubic units" ;  or, write as " units³ " } ;

                                  "r = radius length" ; 

                                  "h = height" ;
_____________________________________________________
  →  Now, we shall solve for the volume, "V", of the given cylinder in this question/problem:
_____________________________________________________

          →   V  = [tex] \pi [/tex]  r²  h  ; 

                      in which: "r = radius = ? "  ; 

                        →  To find "r" ;  We are given the diameter, "d = 40 mm" ; 
 
                         Note that:  "r = d/2 = (40 mm) / 2 = 20 mm " ; 

                              {i.e., "the radius is half of the diameter".}.  

                          " r = 20 mm " ;  

                          " h = height = 30 mm " {given in figure) ; 
      
                        →  For [tex] \pi [/tex] ; let us use " 3.14 " — which is a commonly used approximation.  

             →  For this question/problem, none of the answer choices are given "in terms of [tex] \pi [/tex] " ;
     →   so we shall use this "numerical value" as an "approximation" ; 
_______________________________________________________

Now, let us plug in our known values into the formula;
     and calculate to find the volume, "V", of our given cylinder; as follows:
_______________________________________________________

    →    V  = [tex] \pi [/tex]  r²  h  ; 

                =  (3.14) * (20 mm)²  * (30 mm) ; 

                =  (3.14) * (20)² *  (mm)²  * (30 mm) ;
          
                =  (3.14) * (20)² * (30) * (mm³) ;

                =  (3.14) * (400) * (30) * (mm³) ; 

                =  37, 680 mm³
__________________________________________________

The volume is
:  " 37, 680 mm³  " ;  

          →  which is:  Answer choice  [C]:  " 37, 680 mm³ " .

Two points move along a circle of length 120m with a constant speed. If they move in different directions, then they meet every 15 seconds. When going in the same direction, one point catches up to the second every 60 seconds. Find the speeds of the points.

Answers

Let x and y be the speeds of the two points. The circle is of length 120m that is Circumference of circle is 120m.When the points are moving in opposite directions, they meet in every 15 seconds.That is the points cover 120m in 15 seconds.As they are moving in opposite directions, so the relative speed will be equal to the sum of speeds of both points.Speed= Distance ÷Time = 120÷15=8m per seconds.

x+y=8

When going in the same direction, one point catches up to the second every 60 seconds.Speed= 120÷60=2 m per seconds

x-y=2.

Solving the two equations by elimination method:

x+y=8.

x-y=2

Adding the equations:

2x=10 ,x=5m / sec.

x+y=8

5+y=8

y=3m/sec.

Thus, the speed of the two points is 5 m/s and 3 m/s.

For B, x = 2; 2≤2<6, so the piece of the function we want is f(x) = -x+1.  In our ordered pair, y=f(x)=-1; -2+1=-1, so yes, it is a solution.

For C, x = 8; 8≥6, so the piece of the function we want is f(x) = x.  In our ordered pair, y=f(x)=-7; -7≠8, so no, it is not a solution.

A one-tablespoon serving of olive oil contains 120 calories. The label on a bottle of olive oil states that it contains 66 servings. How many calories are in the whole bottle of olive oil?

Answers

I believe the answer is 7920 calories.

The whole bottle of olive oil contains 7920 calories.

To find the total number of calories in the entire bottle of olive oil, one must multiply the number of calories in one serving by the total number of servings in the bottle.  

Given that one tablespoon serving of olive oil contains 120 calories, and the bottle contains 66 servings, the calculation is as follows:

 Total calories in the bottle = Calories per serving [tex]\times[/tex] Number of servings

Total calories in the bottle = 120 calories/serving [tex]\times[/tex] 66 servings

Total calories in the bottle = 7920 calories

Therefore, the whole bottle of olive oil contains 7920 calories.

A multiple of 1/10 is any fraction obtained by multiplying 1/10 by an integer. For example, 1/10 multiplied by 2 is 2/10, which simplifies to 1/5. Dividing by powers of 10 shifts the decimal point left, making 1.9436 divided by 1,000 equal to 0.0019436.

Explanation:

In mathematics, when identifying a multiple of a fraction, you look for fractions that can be created by multiplying the original fraction by an integer. In the case of 1/10, a multiple would be any fraction where 1/10 is multiplied by a whole number.

For instance:

1/10 multiplied by 2 is 2/10, which simplifies to 1/5 - thus 1/5 is a multiple of 1/10.1/10 multiplied by 3 is 3/10 - hence, 3/10 is a multiple of 1/10.

Multiplying 1.9436 by powers of 10 shifts the decimal point accordingly:

1.9436 × 10 = 19.4361.9436 × 100 = 194.361.9436 × 1,000 = 1,943.6

Conversely, dividing by powers of 10 will shift the decimal point to the left, making the number smaller:

1.9436 ÷ 10 = 0.194361.9436 ÷ 100 = 0.0194361.9436 ÷ 1,000 = 0.0019436

The fraction 15 can be simplified by dividing both the numerator and the denominator by the greatest common factor, in this case, 15, yielding a value of 1.
