The coordinates of parallelogram PVWZ are P(0, 0), V(a, b), and Z(c, 0). Find the coordinates of W without using any new variables.Any help I could get on this one would be great! I don't understand this at all.

Answers

Answer:

Co-ordinates of W must be (c+a,b).

Step-by-step explanation:

We are given that,

PVWZ is a parallelogram with vertices P(0,0), V(a,b) and Z(c,0).

Since, PVWZ is parallelogram.

The possible line segments are PV, VW, WZ and ZP.

Also, as the opposite sides must be parallel for the parallelogram, the co-ordinates will move accordingly.

So, we see from the figure that,

Co-ordinates of W must be (c+a,b).

It is known that a certain function is an inverse proportion. Find the formula for this function if it is known that the function is equal to 12 when the independent variable is equal to 2.

Answers

Answer:

$y=(24)/(x)$

Step-by-step explanation:

We have been given that a certain function is an inverse proportion. We are asked to find the formula for the function if it is known that the function is equal to 12 when the independent variable is equal to 2.

We know that two inversely proportional quantities are in form $y=(k)/(x)$ , where y is inversely proportional to x and k is constant of variation.

Upon substituting $y=12$ and $x=2$ in above equation, we will get:

$12=(k)/(2)$

Let us solve for constant of variation.

$12\cdot 2=(k)/(2)\cdot 2$

$24=k$

Now, we will substitute $k=12$ in inversely proportion equation as:

$y=(24)/(x)$

Therefore, the formula for the given scenario would be $y=(24)/(x)$ .

Find common denominators for three sevens and one and half

Answers

3/7 and 1 1/2

Now look at the two denominators: 7 and 2.

Because 7 and 2 are relatively prime, their least common multiple is:
7*2= 14

Therefore, 14 is a common denominator for 3/7 and 1 1/2.

Hope this helps~

3/7 and 1/2 14 is the common denominator at the end it is 6/14 and 7/14

Given graph of f(x)=k/x and g(x)=x.T(3.16;3.16) is the point of intersection of f and g. Write down the domain of f

Answers

Hello,

As said T is the point of intersection of f and g, this means that there are only one point and that k=+1.

So dom f= $R ^(+)_0$ (x>0)
