Answer:

b. 3.2 seconds

Step-by-step explanation:

Given the 2 functions:

h = 9t

h= -16t² + 60t

When the height is the same for both objects:

9t = -16t² + 60t

0 = -16t² + 60t - 9t

0 = -16t² + 51t

0 = t(-16t + 51)

which has two solutions:

t = 0

or

-16t + 51 = 0

51 = 16t

t = 51/16 = 3.2

Find the area of the regular hexagon.
NeTakaya

Answer:

1) The area of the regular hexagon is approximately 11.256 unit²

2) The coordinates of the center is (2, 3)

3) The base length is approximately 2.08 units

4) The height of the hexagon is approximately 3.61 units

Step-by-step explanation:

1) The length, lₐ, of the apothem is given as follows;

l_a = \sqrt{\left (y_{2}-y_{1}  \right )^{2}+\left (x_{2}-x_{1}  \right )^{2}}

Therefore, for the apothem having coordinates, (2, 3), and (3, 1.5), we have;

l_a = \sqrt{\left (3-1.5  \right )^{2}+\left (2-3  \right )^{2}} = \sqrt{1.5^2 + (-1)^2} =\sqrt{3.25}

The length of half half of one side, S/2 = a × tan(30°) = √(3.25)/√3

The length of the base = 2 × √(3.25)/√3 ≈ 2.082 units

The perimeter, P = 6 × 2× √(3.25)/√3

The area, A = 1/2 × P × a = 1/2 × 6 × 2 × √(3.25)/√3 × √3.25 = (13·√3)/2

A = (13·√3)/2 unit²

The area of the regular hexagon, A =  (13·√3)/2 unit² ≈ 11.256 unit²

2) The coordinates of the center = (2, 3)

3) The base, 'b', length by Pythagorean theorem is given as follows;

b = √(a² + (S/2)²) = √((√(3.25))² + (√(3.25)/√3)²) = √(3.25 + 3.25/3) = √(13/3) = (√39)/3

The base length, b = (√39)/3 units ≈ 2.08 units

4) The height of the hexagon, h = 2 × The length of the apothem, lₐ

The length, lₐ, of the apothem is given as follows;

l_a = \sqrt{\left (y_{2}-y_{1}  \right )^{2}+\left (x_{2}-x_{1}  \right )^{2}}

Given the apothem coordinates, (2, 3), and (3, 1.5), we have;

l_a = \sqrt{\left (3-1.5  \right )^{2}+\left (2-3  \right )^{2}} = \sqrt{1.5^2 + (-1)^2} =\sqrt{3.25}

The height of the hexagon, h = 2 × √3.25 units ≈ 3.61 units.
