If the expression x^{-\frac{3}{2}}y\sqrt{36xy^2}x − 2 3 ​ y 36xy 2 ​ is written in the form ax^by^cax b y c , then what is the p
Mekhanik [1.2K]

Answer:

-12

Step-by-step explanation:

The given expression is

x^{-\frac{3}{2}}y\sqrt{36xy^2}

We have to rewrite the given function in the form of  

ax^{b}y^c          ....(i)

then we have to find the product of a,b and c.

The given expression can be rewritten as

x^{-\frac{3}{2}}y\sqrt{36}\sqrt{x}\sqrt{y^2}

Using properties of exponents we get

x^{-\frac{3}{2}}y6x^{\frac{1}{2}}y       [\because \sqrt[n]{a}=a^{\frac{1}{n}}]

6x^{-\frac{3}{2}+\frac{1}{2}}y^{1+1}      [\because a^ma^n=a^{m+n}]

6x^{-1}y^{2}      ...(ii)

On comparing (i) and (ii), we get

a=6,b=-1,c=2

Product of a,b and c is

abc=(6)(-1)(2)=-12

Therefore, the product of a,b, and c is -12.

The image of a parabolic lens is projected onto a graph. The image crosses the x-axis at –2 and 3. The point (–1, 2) is also on
Nezavi [6.7K]
For x-intercepts "b" and "c", a quadratic can be written as
  y = a(x -b)(x -c)

You know the x-intercepts, so you can write the equation as
  y = a(x +2)(x -3) . . . . . . eliminates the first two answer choices

Substituting (x, y) = (-1, 2), you have
  2 = a(-1+2)(-1-3) = -4a
Then dividing by -4 gives
  -2/4 = a = -1/2 . . . . . corresponds to the third answer choice

The appropriate selection is
  y = -1/2 (x + 2)(x - 3)

There are two outputs of 24. Does this help you determine whether the relation is a function? Explain.
oksian1 [2.3K]

Answer:

This does help you find whether it is a function or not. Since 24 has two outputs, it is not a function.

Step-by-step explanation:

The reason is because for a function to be a function, there must be one input for one out put, it can't have two different outputs.
