Show all work to identify the asymptotes and zero of the function f of x equals 5 x over quantity x squared minus 25
Answer: VA: x = {-5, 5), HA: y = 0, Zeros: x = 0
Step-by-step explanation:
[tex]f(x) = \dfrac{5x}{x^2-25}[/tex]
Vertical asymptotes: The denominator cannot equal zero.
x² - 25 = 0
(x - 5)(x + 5) = 0
x = 5, x = -5
Horizontal Asymptote: Let m represent degree of numerator and n represent the degree of the denominator.
If m > n then NO asymptoteIf m = n, then y = coefficient of m ÷ coefficient of nIf m < n, then y = 0For the given equation, m = 1 and n = 2 so we use option 3 --> y = 0
Zeros: Set the equation equal to zero and solve for x.
[tex]0=\dfrac{5x}{x^2-25}[/tex]
Multiply both sides by x²- 25 --> 0 = 5x
Divide both sides by 5 --> 0 = x
Using function concepts, it is found that:
The zero of the function is [tex]x = 0[/tex].The vertical asymptotes are [tex]x = \pm 5[/tex].The horizontal asymptote is [tex]y = 0[/tex].The function is given by:
[tex]f(x) = \frac{5x}{x^2 - 25}[/tex]
Applying the subtraction of perfect squares, the function will be given by:
[tex]f(x) = \frac{5x}{(x - 5)(x + 5)}[/tex]
The zero is the value of x for which:
[tex]f(x) = 0[/tex]
In a fraction, it is when the numerator is zero, thus:
[tex]5x = 0[/tex]
[tex]x = \frac{0}{5}[/tex]
[tex]x = 0[/tex]
The vertical asymptotes are the values of x which are outside the domain, which in a fraction are the zeroes of the denominator, thus:
[tex](x - 5)(x + 5) = 0[/tex]
[tex]x = \pm 5[/tex]
The horizontal asymptote is:
[tex]y = \lim_{x \rightarrow \infty} f(x)[/tex]
Hence:
[tex]y = \lim_{x \rightarrow \infty} \frac{5x}{x^2 - 25} = y = \lim_{x \rightarrow \infty} \frac{5x}{x^2} = y = \lim_{x \rightarrow \infty} \frac{5}{x} = 0[/tex]

One recipe uses 1/4 cup of red onions.
They have 1 1/2 cups of red onions.
We need to divide 1 1/2 by 1/4.
First, we convert the mixed numeral into a fraction. Then, to divide by a fraction, we multiply by the reciprocal of the fraction.

the sum of 12+12
12+12 is an even
number?
Answer:
An even number is a number that can be divided into two equal halves.
Also even numbers end in one of these digits: 0, 2, 4, 6, or 8
12 + 12 + 12 + 12 = 48
48 with the digit 8
48 divided in half gives two equal halves:
48/2 = 24
The number 24 can be added twice to check that the answer is correct:
24 + 24 = 48
So to summarize:
The sum of 12 + 12 + 12 + 12 is an even number because it can be equally divided in two halves and it ends in the digit 8.

Johnathan picked colored beads from a jar 50 times, replacing the bead each time. He picked a red bead 12 times, a yellow bead 14 times, and a blue bead 24 times. How many blue beads should Johnathan expect to pick out of 150 times?
Answer: 72 beads
Step-by-step explanation:
From the question, we have the information that Johnathan picked colored beads from a jar 50 times and replaced the bead each time. Jonathan picked a red bead 12 times, yellow bead 14 times, and a blue bead 24 times.
Out of 50 picks, the following beads were picked:
Red = 12
Yellow = 14
Blue = 24
Total = 50
Fraction of blue bead = 24/50 × 100
= 48%
The blue beads that Johnathan will pick out of 150 beads will be:
= 48% of 150
= 48/100 × 150
= 0.48 × 150
= 72 blue beads
Jonathan will pick 72 blue beads out of 150 beads.
Answer:
72 beads

Add 1 to both sides
Multiply both sides by 4
Take the square root of both sides
Subtract 5 from both sides
In this problem, you are trying to isolate the x. In order to do that you have to get rid of all the other numbers surrounding it. The first thing you're going to do is move the 1. To get rid of the -1 you have to do a +1. What you do to one side you have to do to the other. Therefore, you have to add +1. Next, you will move the 1/4 by multiplying by the reciprocal which is 4 (because 1/4 x 4 = 1, this gets rid of the 1/4 on the left side). After that you will do the opposite of square, which is to take the square root. Lastly, you will subtract the five for the same reason you added the 1.

The length of a rectangular swimming pool is p m and its width is q m. It is given that the length of the swimming pool is twice its width. If the perimeter of the swimming pool is 150 m, find the values of p and q.
(**please use the simultaneous linear equations in two variables to solve this question)
**if you have answer this question I will choose you to be the brainlest answer**
Answer: q = 25 m, p = 50 m
Step-by-step explanation:
p is the length, and q is the width.Since the length is twice as long as the width, we can come up with the equation: p = 2qSince the perimeter is 150, we can also come up with this formula since the perimeter is all sides added together: 2p + 2q = 150Since we have two equations, we can just plug them into each other. First, let's substitute the 2q in the second equation with p that is defined in the first equation: 2p + p = 150If we simplify that, we get: 3p = 150Now we know that p = 50 m.Now, if you plug in 50 into the first equation you get: 50 = 2q.Next, just simplify, and you know that q = 25 m.Therefore, p = 50 m, q = 25 m.Which equations represent the line that is parallel to 3x − 4y = 7 and passes through the point (−4, −2)?

write a quadratic function f whose zeros are -2 and -9
Answer:
f(x) = x^2 + 11x + 18.
Step-by-step explanation:
As the zeroes are -2 and -9 the factored form is
f(x) = a(x - (-2))(x - (-9)) where a is some constant.
As we want any quadratic function with theses zeros we can let a = 1 so:
f(x) = (x + 2)(x + 9)
f(x) = x^2 + 2x + 9x + 18
f(x) = x^2 + 11x + 18.
The required quadratic function is given as x²+11x+18 = 0,
Given that,
To write a quadratic function f whose zeros are -2 and -9
Functions is the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
Here,
x = -2 and x = -9
x 2 = 0 and x + 9 = 0
The function is given as,
(x + 2)(x + 9) = 0
x²+11x+18 = 0,
Thus, the required quadratic function is given as x²+11x+18 = 0,

Step-by-step explanation:I like using this method:
Put a square which covers this triangle
Find the area of the rectangle which is 20
Half it which is 10
Now you have the area which is 10
Answer: The other answer is incorrect!
Step-by-step explanation:
An easier way is just imagine it being straight and not slanted. Counting the base its 3blocks and counting from the highest point all the way to the base its 4 blocks. Base=3 blocks and height=4 blocks. Substituting into the tirangle area formula which is b(h)/2 (base times height divided by 2).
You have 3x4=12.
Then 12/2=6 blocks
Therefore the area of the given triangle is 6 blocks squared (din)t forget the square).
The other answer is incorrect because this triangle is not half of this rectangle and in this question it’s just a grid (we have to use the grid)!
