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.

3.20 × 105 gallons of tar (SG = 1.20) is stored in a 20.0-ft tall storage tank. What is the total mass of the liquid in the tank

lilavasa [31]

Answer:

Mass of the liquid in the tank will be $1.45\times 10^8kg$

Step-by-step explanation:

We have given volume of tar $V=3.20\times 10^5gallon$

1 gallon = 3.785 liter

So $3.20\times 10^5gallon=3.20\times 10^{5}\times 3.785=12.112\times 10^5liter$

Specific gravity = 1.2

Density of water $=1000kg/m^3$

We know that specific gravity $=\frac{density\ of\ liquid}{density\ of\ water}$

$1.2=\frac{density\ of\ liquid}{density\ of\ water}$

Density of liquid $=1200kg/m^3$

So mass of liquid = volume × density

= $12.112\times 10^5\times 1200=1.45\times 10^8kg$

So mass of the liquid in the tank will be $1.45\times 10^8kg$
