Answer: A line with a slope of 2

Step-by-step explanation: the slope of the line is -1/2 so the negative reciprcal of the slope is 2 (It would be perpendicular to it)

i used m=y2-y2/x2-x1 to figure ou the slope and -(x/y) as the negative reciprcal for the perpendicular line.

Step One

Develop a formula for the perimeter.

Argument

What you see is a semicircle going upwards and another one going downwards. Two semicircles =1 circle.

The "perimeter" [Circumfrence] of a whole circle = 2*pi*r

We are told that whatever you call this the perimeter is 8pi + 16

Step Two

Set up the equation

8pi + 16 = 2*pi*r + 4r Including the line connecting these two.

Step Three

Take out the common factors on the left and right.

8(pi + 2) = 2r(pi + 2) Divide both sides by pi + 2

8 = 2r Divide by 2

4 = r

Sorry. I didn't know the meaning of perimeter. Mathmate is perfectly correct.

Who can help me out with this question???

Answer:

x = 13

Step-by-step explanation:

$a^{2} +b^2 = c^2\\12^2 + 5^2 = c^2\\144 + 25 = c^2\\169 = c^2\\$

Take the square root of both sides

$\sqrt{169} = \sqrt{c^2} \\13 = c$

A bridge connecting two cities separated by a lake has a length of 5927.261 yd. use the table of facts to find the length of the

alex41 [277]

Answer:

the length of the bridge in miles is 3.37 miles

Step-by-step explanation:

The computation of the length of the bridge in miles is shown below:

Given that

The length is 5927.261 yard

As we know that

1760 yard = 1 mile

So 1 yard = 1 ÷ 1760 mile

For 5927.261 yard, the miles would be

= 5927.261 ÷ 1760

= 3.37 miles

Hence, the length of the bridge in miles is 3.37 miles
