You only need to consider when the numerator is 0
4x^2-36x=x (4x-36)
x=0 only. vertical asymptote at x=9

Answer:

x=0 is the root for the given function

Explanation:

We have been given with the function

\frac{4x^2-36x}{x-9}  taking out  4x as the common factor from numerator then we will get

\frac{4x(x-9)}{(x-9)}

Now cancel out the common factor from numerator and denominator we will get

4x=0

\Rightarrow x=0

Hence, x=0 is the zero of the given function

Zero of the function is solution of the function the point where function gives the value zero

The pie chart shows information about the voters in an election 2800 more women voted than men work out the total number of vote
Cerrena [4.2K]

The angle subtended by the women voters are 100° more than the angle subtended by the men voters.

  • The total number of voters are <u>10080 voters</u>

Reasons:

The angle subtended by the men on the pie chart = 130°

The number of women = 2800 + The number of men

Therefore;

Angle subtended by the women voters on the pie chart = 360° - 130° = 230°

The difference between the angle representing women and the angle

representing men = 230° - 130° = 100°

Therefore;

100° = 2800

Which by common ratios gives;

\dfrac{100^{\circ}}{360^{\circ}} = \dfrac{2800}{Total \ number \  of \ voters }

100 × Total number of voters = 2800 × 360

The \  total \  number  \ of  \ voters = \dfrac{2800 \times 360}{100}  = 10080

The total number of voters = <u>10080</u>

Find two positive numbers if their ratio is 8:5 and the difference is 150.
natima [27]
Let's call the two numbers x and y. We can write a system of equations to describe the situation:

5x = 8y

x - y = 150

Let's solve the first equation for x:

x = 8y/5

Now we can use substitution to solve the system by plugging 8y/5 in for x in the second equation:

(8y/5) - y = 150

Simplify:

3y/5 = 150

3y = 750

y = 250

If y = 250, then x is:

x = 8(250)/5 = 400

The answer is 250 and 400.
