Is y-4=2(x-2) and 4x-2y=5 perpendicular
djyliett [7]

Answer:

Therefore,

Slopes are Equal, Hence the Lines are not Perpendicular.

Step-by-step explanation:

Given:

y-4=2(x-2)=2x=-4\\\\y=2x .......Equation ( 1 )

4x-2y=5\\2y=4x-5\\\\y=2x-\dfrac{5}{2}  .......Equation ( 2 )

Comparing with,  

y=mx+c ......General Slope point form  

Where m =slope  

We get  

Slope = m1 = 2   For Equation ( 1 )

Slope = m2 = 2   For Equation ( 2 )

Hence,

m1=m2[=2

Therefore, Slopes are Equal Hence the Lines are Parallel not Perpendicular.

For Perpendicular we require

m1\times m2=-1

Therefore,

Slopes are Equal, Hence the Lines are not Perpendicular.

WILL GIVE BRAINLEIST! :Given a traffic cone has a base diameter of 12 inches and a height of 28 inches, which is the closest vol
lesya [120]

Answer:

1,055.58 in^3

Step-by-step explanation:

The volume of a cone is given by

V = 1/3 pi r^2 h

We need the radius

r = d/2 = 12/2 =6

V = 1/3 (pi) (6)^2 *28

Using the pi button on the calculator

   =1055.575132

Rounding to 2 decimal places

 1,055.58 in^3

I will mark as brainliest. Area of a square is 25^m. Find its Perimeter. With working please
77julia77 [94]

Answer:

perimeter = 20 m

Step-by-step explanation:

given the area of the square = 25 m² and

area of a square = s² ( where s is the side length ), then

s² = 25 ( take the square root of both sides )

s = \sqrt{25} = 5 ← length of side

perimeter = 4s = 4 × 5 = 20 m
