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,

Answer:

the value of  line ST is 6 centimeters long

Step-by-step explanation:

The attached image in conjunction with the question is shown in the file below.

We can see from the RT segment that the equation given can be expressed as:

[tex]\mathbf{2x+3x = 10}[/tex]

so; if we solve for x ; we have ;

[tex]\mathbf{5x= 10}[/tex]

divide both sides by 5 ; we have:

[tex]\mathbf{\dfrac{5x}{5}= \dfrac{10}{5}}[/tex]

[tex]\mathbf{x=2}[/tex]

However ; the value of ST is represent by the information:

[tex]\mathbf{ ST = 3x}[/tex]

replcaing the value for x; we have :

[tex]\mathbf{ ST = 3*2}[/tex]

[tex]\mathbf{ ST = 6}[/tex]

Thus, the value of  line ST is 6 centimeters long

Answer:

True, r represents the distance from a point to the pole when plotting that point in polar coordinates.

Step-by-step explanation:

Given: The statement '' The value of r represents the distance from a point to the pole when plotting that point in polar coordinates ''

To state: whether the given statement is true or false

Solution:

In the cartesian coordinate system, any point is represented by the coordinates  [tex](x,y)[/tex]

In polar-coordinates system, distance of the point from the origin (pole)(r) and the angle [tex](\theta)[/tex] that the line joining the point to the origin makes with the positive  x -axis are used as polar coordinates. Polar coordinates are of form [tex](r,\theta)[/tex]

True, r represents the distance from a point to the pole when plotting that point in polar coordinates.

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)!

Trust me I know this.

Answer:

B & D

Step-by-step explanation:

Answer:

length of rectangle = 5

width of rectangle = 5

Area of rectangle = 25

Step-by-step explanation:

Since the length of the rectangle is "x", and the value of the area is given by the product of the length "x" times the width "10-x", indeed, the area "y" of the rectangle is given by the equation:

[tex]y=x\,(10-x)=10x-x^2[/tex]

Now, they tell us that the area of the rectangle is such that coincides with the maximum (vertex) of the parabola this quadratic expression represents. So in order to find the dimensions of the rectangle and therefore its area, we find the x-coordinate for the vertex, and from it, the y-coordinate of the vertex, which is the rectangle's actual area.

Recall that the formula for the x of the vertex of a quadratic of the form :

[tex]y=ax^2+bx+c[/tex]

is given by the formula:

[tex]x_{vertex}=-\frac{b}{2\,a}[/tex]

which in our case gives:

[tex]x_{vertex}=-\frac{b}{2\,a}\\x_{vertex}=-\frac{10}{2\,(-1)}\\x_{vertex}=5[/tex]

Therefore, the length of the rectangle is 5, and its width (10-x) is also 5.

The area of the rectangle is therefore the product of these two values: 5 * 5 = 25

Which should coincide with the value we obtain when we replace x by 5 in the area formula:

[tex]y=10x-x^2\\y=50-(5)^2\\y=50-25\\y=25[/tex]

Answer:

x = 50

Step-by-step explanation:

Let x be the original number.

This question can be expressed as:

0.4x = 20

0.4 of the original number is 20.

Now, we can directly solve for x:

4x = 200

x = 50

Answer:

8

Step-by-step explanation:

40 times 0.20 is 8.

You can also use 40 percent of 20, which is also 8, but the original is easier to comprehend.

The answer would be, 36 sq m

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.

For 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 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]

Step-by-step explanation:

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.

Answer: y-2=2/5(x-17), y=1/3x-2/5

Step-by-step explanation:

Answer:

1.)y+6=2/5(x+3)

2.)y=1/3x-2/5

Step-by-step explanation:

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.

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.
