Simplify The numerator

4 {a}^{2}    -   {b}^{2}  = (2a + b)(2a - b)

\sqrt{ \frac{(2a + b)(2a - b)}{9a} }

\sqrt{9a}  =  \sqrt{9}  \times  \sqrt{a}

3 \times  \sqrt{a}

\sqrt{ \frac{(2a + b)(2a - b)}{3 \sqrt{a} } }

RATIONALIZE

\frac{ \sqrt{a} \sqrt{(2a + b)(2a - b)}  }{3 \sqrt{a } \times  \sqrt{a}  }

\sqrt{ \frac{a(2a + b)(2a - b)}{3a} }. This is the answer

The sum of two even consecutive integers is 114. What is the smallest integer?
Ainat [17]

Answer:

56

Step-by-step explanation:

The sum of two <em>even</em> consecutive integers is 114.

Let's let the first even integer be 2n, where n is <em>some</em> integer: it doesn't matter what n is, but if we multiply n by 2, we are certainly getting an even number. This is because any integer multiplied by 2 is even.

So, this means that the second number is 2n+2.

Their sum is 114. In other words:

(2n)+(2n+2)=114

Solve for n.

Combine like terms:

4n+2=114

Subtract 2 from both sides:

4n=112

Divide both sides by 4:

n=28

So, n is 28.

This means that the first number is 28(2) or 56.

And the second number is 58.

So, the smallest integer is 56.

And we're done!

Which graph represents an exponential function?
Paha777 [63]

Answer:

A simple exponential function to graph is y=2x . Notice that the graph has the x -axis as an asymptote on the left, and increases very fast on the right. Changing the base changes the shape of the graph. Replacing x with −x reflects the graph across the y -axis; replacing y with −y reflects it across the x -axis.

What is the discontinuity of the function f(x)=x^2-3x-28/x+4?
Hitman42 [59]

Answer:

Option D is correct that is (-4,-11).

Step-by-step explanation:

We have been given an expression:

f(x)=\frac{x^2-3x-28}{x+4}

We need to find the points of discontinuity

We will first factorize the given expression

\frac{x^2-7x+4x-28}{x+4}

\Rightarrow \frac{x(x-7)+4(x-7)}{x+4}

\Rightarrow \frac{(x+4)(x-7)}{x+4}

Hence, the point of discontinuity is where denominator gives value zero

So, x+4=0\Rightarrow x=-4

Point of discontinuity is -4

hence, after removing the point of discontinuity the function left is:

f(x)=x-7

Hence, put x=-4

f(-4)=-4-7=-11

Therefore, option D is correct that is (-4,-11).
