A circle has diameter of 11cm
dlinn [17]

Since length of diagonal (  Diagonal= 9.9cm ) is less than diameter of circle ( 11 cm ) , Therefore , the square will fit inside the circle without touching the edge of the circle.

<u>Step-by-step explanation:</u>

Here we have , A circle has diameter of 11 cm  A square has side length of 7 cm . Use Pythagoras’ Theorem to show that the square will fit inside the circle without touching the edge of the circle . Let's find out:

We know the concept that for any square to fit inside the circle without touching the edge of circle  , diagonal of square must be less than diameter of circle  . Let's find out length of diagonal by using Pythagoras Theorem :

Hypotenuse ^2 = Perpendicular^2+Base^2

For a square , Perpendicular = base = side

⇒ Diagonal^2 = 2(side)^2

⇒ Diagonal= \sqrt{2}(side)

⇒ Diagonal= \sqrt{2}(7)

⇒ Diagonal= 9.9cm

Since length of diagonal (  Diagonal= 9.9cm ) is less than diameter of circle ( 11 cm ) , Therefore , the square will fit inside the circle without ruching the edge of the circle.

Consider the line 2x-7y=-7. Find the equation of the line that is perpendicular to this line and passes through the point (-8,-6
monitta

Step-by-step explanation:

2x - 7y = -7

2x + 7 = 7y

y = (2/7)x + 1

the slope of the line is the factor of x : 2/7

FYI that is the ratio y/x and means, when x changes by 7 points to the plus (right) side, then y changes 2 points to the plus (up) side.

the parallel line will have the same slope, of course. just a different y-axis-interception point. that means, the "+" term at the end changes. changes to what ?

well, we use the given point coordinates

-6 = (2/7)×-8 + c

-6 = -16/7 + c

-42/7 = -16/7 + c

-26/7 = c

so, the equation of the parallel line is

y = (2/7)x - 26/7

y = (2/7)×(x - 13)

the perpendicular line is a line that intercepts our original line with a 90 degree angle.

that means its slope will switch x and y of the original line slope and also flips the sign (from + to - or vice versa).

=> the slope of the perpendicular line is -7/2.

the line equation looks like

y = (-7/2)x + c

and again, we use the given point coordinates to find the missing c (y-intercept).

-6 = (-7/2)×-8 + c

-6 = -7×-4 +c

-6 = 28 + c

-34 = c

so, the full equation of the perpendicular line is

y = (-7/2)x - 34
