The shipping box has a length of 30 inches and a height of 6 inches. How wide should the box be to fit the 36-inch bat? Show and explain your work.

Answers

Answer:

width = 18.97 inches

Step-by-step explanation:

To find the smallest width of the box to fit the bat, we need to put the bat in the diagonal of the box.

The diagonal of the box is given by:

diagonal^2 = length^2 + width^2 + height^2

Then, using the diagonal = 36 inches, length = 30 inches and height = 6 inches, we have:

36^2 = 30^2 + width^2 + 6^2

1296 = 900 + width^2 + 36

width^2 = 360

width = 18.97 inches

determine how many different values can arise by inserting one pair of parentheses into the given expression. 3 − 7 − 9 − 5

Answers

Answer:

Step-by-step explanation:

(3 - 7) - 9 - 5 = -4 - 9 - 5

                   = -18

3 - (7 - 9) - 5 = 3 - (-2) - 5

                    = 3 + 2 - 5

                    = 5 - 5

                    = 0

3 - 7 - (9 - 5) = 3 - 7 - 4

Solve system of equations for x + y: 3x + 2y = -18 & 2x + 9y =-12

Answers

Answer:

(- 6, 0 )

Step-by-step explanation:

Given the 2 equations

3x + 2y = - 18 → (1)

2x + 9y = - 12 → (2)

Multiplying (1) by 2 and (2) by - 3 and adding will eliminate the term in x, that is

6x + 4y = - 36 → (3)

- 6x - 27y = 36 → (4)

Add (3) and (4) term by term to eliminate x

- 23y = 0

y = 0

Substitute y = 0 into either of the 2 equations and evaluate for x

Substituting into (1)

3x + 0 = - 18

3x = - 18 ( divide both sides by 3 )

x = - 6

Solution is (- 6, 0 )

A parabola can be represented by the equation x2 = 2y.

Answers

Answer:

b)

i) Focus ( 0,a) = [tex](0,\frac{1}{2} )[/tex]

ii) The equation of the directrix is

                            [tex]y = -\frac{1}{2} or y +\frac{1}{2} =0[/tex]

Step-by-step explanation:

Step(i):-

  A parabola is the set of all points in a plane that are equidistant from a fixed line and a fixed point (not in a line) in the plane

• The Fixed line is called the directrix of the parabola.

• The Fixed point is called the focus of the parabola.

• A line through the focus and perpendicular to the directrix is called the axis of the parabola.

• The point of intersection of parabola with the axis is called the vertex of the parabola.

Given Parabola x² = 2 y

Comparing  x² = 4 a y

                   4 a = 2

                     [tex]a = \frac{1}{2}[/tex]

  Focus ( 0,a) = [tex](0,\frac{1}{2} )[/tex]

Step(ii)

The equation of the directrix is y = -a or y +a=0

The equation of the directrix is

                            [tex]y = -\frac{1}{2} or y +\frac{1}{2} =0[/tex]

The equation of the directrix is 2 y +1 =0
