Use the distance formula to find the length of one of the longer lines and do the same for one of the shorter ones.

Longer line using the points (-5,5) and (0,-5):-
length = sqrt ( 5-- 5)^2 + ( -5-0)^2 = sqrt 125

short line:- using the points (-5,5) and (-1,7)
length = sqrt (-5--1)^2 + (5-7)^2 ) = sqrt 29

So the area of the rectangle = sqrt125 * sqrt29 = 60.21 to nearest hundredth

You spin the spinner once.<br><br> What is P(not 7)?

Flura [38]

Answer:

12.5%

Step-by-step explanation:

The spinner has 8 equal sections, numbered 1, 2, 3, 4, 5, 6, 7, and 8. The only number greater than 7 is 8. There is 1 number greater than 7.

P(greater than 7) =

Write your answer as a decimal. Then convert your answer to a percentage.

= 0.125 = 12.5%

P(greater than 7) = 12.5%

A suspension bridge with weight uniformly distributed along its length has twin towers that extend 85 meters above the road surf

Dmitry_Shevchenko [17]

Answer:

The required height of the cable is 21.25 meter

Step-by-step explanation:

Consider the provided information.

A suspension bridge with weight uniformly distributed along its length has twin towers that extend 85 meters above the road surface and are 800 meters apart.

Let the road surface is the x-axis, and the point (0,0) represents the point that is on the road surface midway between the two towers.

Now it will form an upward parabola whose vertex is at (0,0), one on either side of vertex at a distance x= 400 or x= -400, and y for each of these points is 85.

The equation of parabola is: $y=ax^2$
