A soccer player kicks the ball down the field to a teammate. The height of the soccer ball above the ground, h, in relation to t

he time in seconds, t, is represented by the quadratic function shown in the table.
Time (seconds) Height (feet)
0 0
0.5 12
1 16
1.5 12
Use the table to complete the statements.

The height of the soccer ball above the ground is symmetric about the line t =
second(s).

The ball landed on the ground at t =
second(s).

Answer: for Plato the first t = 1 second

And the second t=2 seconds

Step-by-step explanation:

Just took the test I got 5/5

you can see that the height is the same at 0.5sec and 1.5 sec (12ft)

so therefore the height is symmetric about the line t=(midpoint of 0.5 and 1.5)

(0.5+1.5)/2=2/2=1

so the height is symmetric about the line t=1


the ball lands on the ground when height=0

since it is symmetric about t=1, and at t=0, the height is 0

1-0=1, so the difference between symmetry and desired height is 1

we must go in the oposite direction to find the next 0 height

so from symmetry to 0 height is 1+1=2, so at t=2 seconds

If X=20°, Y=135°, what will Z be
Veronika [31]

The value of Z would be 225°

<h3>What is the angle at a point?</h3>

The angle at a point are angles that add up to 360°

Thus, X + Y + Z = 360°

X = 20°

Y = 135°

Then, Z = 360° - X - Y

Z = 360° - 20° + 135°

Z = 360° - 155°

Z = 205°

Therefore, the value of Z is 205°

N + (18 - 6) = 32 who can help me?
MissTica

Answer:

20

Step-by-step explanation:

N + (18 - 6) = 32

Simplify bracket

N + 12 = 32

Subtract 12 from both sides to eliminate 12 on the left side

N + 12 - 12 = 32 - 12

N = 20

A rectangular piece of paper has a width that is 3 inches less than its length. It is cut in half along a diagonal to create two
Oliga [24]

Let

x-------> the length of the rectangle

y------> the width of the rectangle

we know that

The area of the rectangle is equal to

A=x*y

The area of the two congruent right triangles  is equal to the area of the rectangle

A=2*44=88\ in^{2}

so

88=x*y -------> equation A

y=x-3 -----> equation B

Substitute equation B in equation A

x*[x-3]=88

x^{2} -3x-88=0 --------> equation that can be used  to solve for the length of the rectangle

Using a graph tool-------> solve the quadratic equation

see the attached figure

The solution is

x=11\ in -----> the length of the rectangle

Find the value of y

88=11*y

y=8\ in  ----> the width of the rectangle

Statements

<u>case A)</u> The area of the rectangle is 88 square inches

The statement is True

See the procedure

<u>Case B)</u> The equation  x*[x-3]=44 can be used to solve for the dimensions of the triangle

The statement is False

Because, the equation x*[x-3]=88 can be used to solve for the dimensions of the triangle

<u>case C)</u> The equation x^{2} -3x-88=0 can be used to solve for the length of the rectangle

The statement is True

see the procedure

<u>case D)</u>The triangle has a base of 11 inches and a height of 8 inches

The statement is True

Because, the base of the triangle is equal to the length of the rectangle and the height of the triangle is equal to the width of the rectangle

<u>case E)</u> The rectangle has a width of 4 inches

The statement is False

See the procedure
