The density of steel is 7.8 grams per cubic centimeter. What is the volume of a piece of a sheet of steel that has a mass of 3.75 kilograms?

Answers

Answer 1

Answer: Density is the measure of the weight of the object at a certain volume or the volume of an object with a certain weight. To solve for density we are to divide the weight by the volume.
Now, we are asked for the volume given density and mass. The answer is 480cm^3. Note: Make sure the units are consistent.

Prove that any number raised to the 0'th power equals 1

Answers

(a number)^to the 'A' power, divided by (the same number)^to the 'B' power =

   (the same number)^(A - B) power

If 'A' = 'B', then the numerator and the denominator are both

   (the same number)^to the same power,

and since (A - B = 0) , the quotient is   (the same number)^to the ( 0 ) power.

But a fraction with the same thing in the numerator and the denominator is '1 '.

A line passes through (1,1) , (-2,4) , and (6,n) . Find the value of n.

Answers

Answer:

$n=-4$

Step-by-step explanation:

The line passes through the points $\left ( 1,1 \right ),\:\left ( -2, 4\right ),\:\left ( 6,n \right )$

We know that equation of a line passing through two given points $\left ( x_(1),y_(1) \right )$ and $[tex]y-1=(4-1)/(-2-1)\left ( x- 1\right )$ [/tex]

Here, $x_(1) =1, x_(2) =-2,y_(1) =1,y_(2) =4$

So, equation of the line is $y-1=(4-1)/(-2-1)\left ( x- 1\right )$

$y-1=(3)/(-3)\left ( x- 1\right )$

$y-1=-x+1$

$x+y=2$

So, the equation of the line is $x+y=2$ .

As, the point $(6,n)$ lies on the line, will satisfy the equation of the line.

$6+n=2\:\:\left [\because x=6,y=n\right ]$

$n=-4$

Hence, the value of n is $-4$ .

-4.

The equation for a line is y-y₁=m(x-x₁)
Using the following:
x₁= 1
x₂= -2
y₁= 1
y₂= 4

and slope, or m, is (x₂-x₁)/(y₂-y₁),

You can now fill out the equation!
y-(1)=-1(x-(1))
y= -x+2

And solve by substituting the 6, or x₃, into the equation to find the corresponding y value:

y= -(6)+2
y= -4

Therefore,
n=-4
