By undestanding the theory behind rational functions and functional theory, we conclude that the function have:

Domain: (- ∞, - 3) ∪ (- 3, + ∞)

Range: (- ∞, 0) ∪ (0, + ∞)

In this question we have a rational function and we must determine its domain and range, whose elements exist if and only if the denominator evaluated at respective point is distinct of zero. Graphically speaking, the domain of the function represents the set of x-values, whereas the range represents the set of y-values.

By a graphing tool (i.e. Desmos) we construct the rational function and derive the following conclusions:

Domain: (- ∞, - 3) ∪ (- 3, + ∞)

Range: (- ∞, 0) ∪ (0, + ∞)

By undestanding the theory behind rational functions and functional theory, we conclude that the function have:

Answer:

well if you're looking for angles then

angle ADB = 30°

angle CBD = 80°

angle CDB = 120°

but they asked to classify triangle ADC ,whose measurements are 90° , 40° and 50° ...so of they're asking what type of triangle then it is a right angled triangle.

Answer:

Triangle ADC is a right triangle.

Step-by-step explanation:

Triangles Classification

An acute triangle is a triangle with three acute angles or with less than 90° each.

An obtuse triangle has one obtuse angle or more than 90°.

A right triangle has one right angle of 90°

From the figure, we can see angle D is marked as a right angle (90°), thus triangle ADC is a right triangle.

To complete the answer, triangle ADB is obtuse (has an angle of 100°), and triangle ABD is acute.

Answer:

The probability that five of the eight students exhibit an higher IQ than the median of the general population is 0.21875

Step-by-step explanation:

The given parameters are;

The number of students in the sample, n = 8

The number of the students, x, that exhibit higher IQ's than the median = 5

The probability of obtaining the given result by chance is given as follows;

P(x) = n!/((n - x)!x!) × pˣ × qⁿ⁻ˣ

The probability that a student exhibit higher IQ's than the median = 0.5 = p

Similarly, we have, the probability that a student exhibit lower IQ's than the median = 0.5 = q

Substituting the known values, gives;

P(5) = (8!/((8 - 5)!×5!)) × 0.5^(5) × 0.5^(8 - 5) = 0.21875

Therefor, the probability that 5 of the 8 students exhibit an higher IQ than the median of the general population, P(5) = 0.21875.

Answer:

x = -1

Step-by-step explanation:

The axis of symmetry of the graph [tex]y=(x-3)^2[/tex] is  x=3 but,

If shift the graph 4 units to the left it would mean the new value of x would be -1 as shown here:

[tex]x=3-4\\x=-1[/tex]

-4 because it shifted 4 units to the left so the axis of symmetry of the transformed graph would be x = -1 and since it shifted 2 units down the y-coordinate of the turning point would be -2 so the turning point of the original graph is (3 , 0) and the turning point of the transformed graph is

Answer:

$442

Step-by-step explanation:

Multiply the sales price by the discount percentage. This is the total discount that was taken off.

$520 x 15% = $78.

Subtract the discount amount from the sales price. This gives you the amount that the computer costs after the discount.

$520 - $78 = $442

The computer costs $442.

Answer:

C y = 7x +19

Step-by-step explanation:

There are 19 gallons in the water tank and 7 gallons are added when you take x amount of minutes, which gives you y.

An example is 1 minute.

Y = 7(1) + 19

y = 7 + 19

y = 26

You have to remember that there are 19 gallons already in the tank and that 1 minute has passed, which means 7 gallons have been added. Thus there are 26 gallons in the water tank.

Answer:

The maximum height it reaches is 20 meters

The time taken by it to reach the height is 2 seconds

Step-by-step explanation:

The formula of the height of the stone is h = u t - [tex]\frac{1}{2}[/tex] g t², where

∵ A stone is thrown vertically upwards with an initial velocity of 20 m/s

∴ u = 20 m/s

∵ g = 10 m/s²

→ Substitute them in the equation above

∴ h(t) = 20t - [tex]\frac{1}{2}[/tex] (10) t²

∴ h(t) = 20t - 5t²

→ Arrange the terms of the right side according to the greatest power of t

∴ h(t) = -5t² + 20t

To find the maximum height and the time of it find the vertex of the quadratic function (m, k), where m = [tex]\frac{-b}{2a}[/tex] and k is the value of h at t = m, a is the coefficient of t² and b is the coefficient of t

∵ The coefficient of t² is -5

∴ a = -5

∵ The coefficient of t is 20

∴ b = 20

→ Use them to find h

∵ m = [tex]\frac{-20}{2(-5)}[/tex] = [tex]\frac{-20}{-10}[/tex] = h

∴ m = 2

→ Substitute it in the equation above to find k

∵ h(m) = k

∵ k = -5(2)² + 20(2)

∴ k = -5(4) + 40

∴ k = -20 + 40

∴ k = 20

∴ The coordinate of the vertex of the function are (2, 20)

→ m represents the time of the maximum height and k represents

  the maximum height

∴ The maximum height it reaches is 20 meters

∴ The time taken by it to reach the height is 2 seconds

Answer:

the length of the diagonal BD is 8 cm

Step-by-step explanation:

The computation of the length of diagonal BD is as follows

Here the trapezoid diagonals divides each other in an equivalent ratio

So, equation would be

AO ÷ OC = OB ÷ OD

Now put there values to the above equation

3 ÷ 1 = 6 ÷ OD

3OD = 6

Now divided it by 3 in both the sides

OD = 2

Now the BD would be

= BO + OD

= 6 +  2

= 8 cm

hence, the length of the diagonal BD is 8 cm

Answer:

21.74 But if it tells you to round I would round to 21 lbs

Step-by-step explanation:

its basically just a ratio of 92 to 20

92/20=4.6

92-20=72% the amount that is lost

so given that the plum is 100 lbs we know that 72% is depleted

(72/92 = .78)X100= 78 lbs depleted

Lastly 100-78 =22 for the remaining weight of the prunes.

Answer:

[tex]\sqrt[3]{2y^3} * 7\sqrt{18y} = 21(y^{\frac{3}{2}})(2^{\frac{5}{6}})[/tex]

Step-by-step explanation:

The question is poorly formatted.

Given

[tex]\sqrt[3]{2y^3} * 7\sqrt{18y}[/tex]

Required

Derive an equivalent expression

[tex]\sqrt[3]{2y^3} * 7\sqrt{18y}[/tex]

Express 18 as 9 * 2

[tex]\sqrt[3]{2y^3} * 7\sqrt{9 * 2y}[/tex]

Split the expression as follows:

[tex]\sqrt[3]{2y^3} * 7\sqrt{9} * \sqrt{2y}[/tex]

Take positive square root of 9

[tex]\sqrt[3]{2y^3} * 7*3 * \sqrt{2y}[/tex]

[tex]\sqrt[3]{2y^3} * 21 * \sqrt{2y}[/tex]

[tex]21*\sqrt[3]{2y^3} * \sqrt{2y}[/tex]

The cube root can be rewritten to give:

[tex]21*\sqrt[3]{2}*\sqrt[3]{y^3} * \sqrt{2y}[/tex]

[tex]\sqrt[3]{y^3} = y^{3*\frac{1}{3}} = y[/tex]

So, we have:

[tex]21*\sqrt[3]{2} * y * \sqrt{2y}[/tex]

Rewrite as:

[tex]21y *\sqrt[3]{2} * \sqrt{2y}[/tex]

Split [tex]\sqrt{2y[/tex]

[tex]21y *\sqrt[3]{2} * \sqrt{2} * \sqrt{y}[/tex]

Collect Like Terms

[tex]21y*\sqrt{y} *\sqrt[3]{2} * \sqrt{2}[/tex]

Represent in index form

[tex]21y*y^{\frac{1}{2}} *2^\frac{1}{3} *2^\frac{1}{2}[/tex]

Apply law of indices

[tex]21*y^{1+\frac{1}{2}} *2^{\frac{1}{3} +\frac{1}{2} }[/tex]

[tex]21*y^{\frac{2+1}{2}} *2^{\frac{2+3}{6}}[/tex]

[tex]21*y^{\frac{3}{2}} *2^{\frac{5}{6}}[/tex]

[tex]21(y^{\frac{3}{2}})(2^{\frac{5}{6}})[/tex]

Hence:

[tex]\sqrt[3]{2y^3} * 7\sqrt{18y} = 21(y^{\frac{3}{2}})(2^{\frac{5}{6}})[/tex]

Answer: Cada cuaderno cuesta 20, y el libro 120.

Step-by-step explanation:

Vamos a definir:

L = precio de un libro

C = precio de un cuaderno.

Sabemos que Diego compro un libro y tres cuadernos por 180, entonces tenemos:

1*L + 3*C = 180

También sabemos que el libro costo el doble de lo que costaron los 3 cuadernos juntos, entonces:

L = 2*(3*C) = 6*C

Tenemos un sistema de ecuaciones:

1*L + 3*C = 180

L = 6*C

Para resolverlo, podemos reemplazar la segunda ecuación en la primera, para así obtener:

1*(6*C)  + 3*C = 180

6*C + 3*C = 180

9*C = 180

C = 180/9 = 20

Cada cuaderno costo 20.

Y el precio del libro se puede obtener con la ecuación:

L = 6*C = 6*20 = 120

El libro costo 120

Answer:

The maximum price per share is $250 and it happens after 10 days of trading.

Step-by-step explanation:

The performance of a stock is modeled by the function:

[tex]P(d)=-2.5d^2+50d[/tex]

Where d is the number of days of trading and P is the price per share.

To find the maximum price, we use the first derivative:

[tex]P'(d)=-5d+50[/tex]

Equating to zero:

-5d+50=0

Solving for d:

-5d = -50

d = -50/(-5) = 10

d = 10

The price for d=10 is:

[tex]P(10)=-2.5*10^2+50*10[/tex]

[tex]P(10)=-2.5*100+500= 250[/tex]

The maximum price per share is $250 and it happens after 10 days of trading.

Answer:

the second graph

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

The triangle which shows the new location would be Triangle B.

From the coordinates of XYZ transformed to coordinates of triangle X'Y'Z', we can see that the transformation pattern is;

(x, y) -----> (-y, x)

Consider the point be having coordinates (x,y).

Case 1: If the point is in first quadrant:

Subcase: Clockwise rotation, Then (x,y) → (y, -x)

Subcase: Counterclockwise rotation:

Then (x,y) → (-y, x)

Case 2: If the point is in second quadrant:

Subcase: Clockwise rotation, Then (x,y) → (y, -x)

Subcase: Counterclockwise rotation:

Then (x,y) → (-y, x)

On origin, No effect as we assumed rotation is being with respect to origin.

Now, this pattern of transformation occurs when Triangle A is rotated 270° counterclockwise with the origin as the center of rotation to create a new figure.

However, the other rotation that can be used to achieve this is a 270° counterclockwise rotation. so the correct option triangle is B.

Answer:

13

Step-by-step explanation:

Let PS = x and RP = x-5

Using Pythagorean theorem on the two smaller rt triangles formed,

6^2 + x^2 = (ST)^2

6^2 + (x-5)^2 = (RT)^2

Now use Pythag on big triangle and sub in above values:

(2x-5)^2 = 6^2 + x^2 + 6^2 + (x-5)^2

Multiply out and simplify to

x^2 - 5x -36 = 0

Factor the quadratic: ((x-9)(x+4)=0  Therefore x=9 or x=-4.  We may disregard the negative answer so x = 9.  So PS is 9 and RP is 4.

Therefore entire hypotenuse is 4 + 9 or 13.
