The Grand Canyon Skywalk at Eagle Point is a horseshoe shaped steel frame with a glass floor looking down to the Grand Canyon be

yulyashka [42]

Answer: It will be needed 864 square feet of glass to cover the Skywalk floor.

Step-by-step explanation: The figure below shows the area in question.

Area of a circle is given by

$A=\pi.r^{2}$

The walkway is a semicircle. Then, area will be:

$A=\frac{\pi.r^{2}}{2}$

The area that will be covered with glass is the area between the outer and the inner circles. So, area is

$A_{t}=A_{outer}-A_{inner}$

$A_{t}=\frac{\pi.r_{o}^{2}}{2}- \frac{\pi.r_{i}^{2}}{2}$

$A_{t}=\frac{\pi}{2}(32.5^{2}-22.5^{2})$

$A_{t}=\frac{\pi}{2}(550)$

$A_{t}=$ 864

To cover the Skywalk floor is needed 864 $ft^{2}$  of glass.

Write an equation of a line that is parallel to y=2x-5 that passes through the point (2,6).

inessss [21]

Answer: Parallel lines have the same slope

y = 2x +b

Use the given point (2, 5)

5 = 2(2) +b

b = 5 -4 = 1

The equation of the line is

y = 2x +1

Note general form of the slope-intercept form of a line is y = mx +b, where m is the slope and b is the y-axis intercept
