Answer:

Step-by-step explanation:

The equation ...

  g(x) = a·f(x -h) +k

indicates a vertical stretch by a factor of "a", a horizontal translation to the right by "h" units, and a translation up by "k" units.

Matching the shapes of the curves, we see that the point of inflection of f(x) is (-2, -1). The corresponding point on g(x) is (2, -1). This is called the "turning point" in your question. It is where the graph turns from being concave downward to being concave upward.

The difference in x-values between g(x) and f(x) for the turning point is ...

  2-(-2) = 4

This is the amount by which the graph of f(x) is translated to the right: 4 units.

The vertical difference between the marked points on f(x) and the turning point is 1 unit. On g(x), those same marked points are 3 units away from the turning point vertically. Hence the vertical stretch factor is 3.

_____

Comment on the transformation of f(x)

Please note that the graph of g(x) is actually related to the graph of f(x) as ...

  g(x) = 3·f(x -4) +2

That is, for x=1 on g(x), the y-coordinate is ...

  g(1) = 3·f(1 -4) +2 = 3·(-2) +2 = -4 . . . . . . . point (1, -4) on g(x)

For x=3 on g(x), the y-coordinate is ...

  g(3) = 3·f(3 -4) +2 = 0 +2 = 2 . . . . . . . . . . point (3, 2) on g(x)

It may seem a little strange that there is a vertical translation of 2 units upward, when the point of inflection has the same vertical location. Actually, that is the clue that there is an upward translation.

The stretch factor operates about the origin, so stretching f(x) by a factor of 3 will make the turning point move from y=-1 to y=3·(-1) = -3. Since it shows on the graph of g(x) at location y=-1, it must have been translated 2 units upward from its stretched location.

Answer:

The domain of g(x) is {xI x > -5} ⇒ first answer

Step-by-step explanation:

* Lets talk about the transformation at first

- If the function f(x) translated horizontally to the right  

 by h units, then the new function g(x) = f(x - h)

- If the function f(x) translated horizontally to the left  

 by h units, then the new function g(x) = f(x + h)

- If the function f(x) translated vertically up  

 by k units, then the new function g(x) = f(x) + k

- If the function f(x) translated vertically down  

 by k units, then the new function g(x) = f(x) – k

* lets revise the meaning of the domain

- The domain is all values of x that make the function defined

- Find the values of x which make the function undefined

- The domain will be all the real numbers except those values

* Now we can solve the problem

∵ f(x) = √x

- f(x) translated 5 units to the left, then add x by 5

∴ f(x) ⇒ f(x + 5)

- f(x) translated 3 units up, then add f(x) by 3

∴ f(x) ⇒ f(x) + 3

- The function g(x) is created after the transformation

∴ g(x) = f(x + 5) + 3

∵ f(x) = √x

∴ g(x) = √(x + 5) + 3

- The function will be defined if the value under the square root

  is positive (means greater than 0)

∵ The expression under the square root is x + 5

∴ x + 5 > 0 ⇒ subtract 5 from both sides

∴ x > -5

- The domain will be all the real numbers greater than -5

∴ The domain of g(x) is {xI x > -5}

The domain of the function g(x), which is the function f(x) = square root of x translated left 5 units and up 3 units, is {x | x > -5}.

The original function f(x) has a domain of {x | x ≥ 0} because we cannot take the square root of a negative number. When the function is translated left 5 units, the new function, g(x), will start at x = -5 instead of x = 0, reflecting the domain shift due to translation. Therefore, the domain of g(x) is {x | x > -5}.

Answer:

Step-by-step explanation:

D is correct.  For any x in the domain of your function, there can be ONLY ONE corresponding y value.  If you find more than one y value associated, then this relationship is NOT a function.

Answer: D. A function is a set of ordered pairs in which each first component in the ordered pairs corresponds to exactly one second component.

Step-by-step explanation: In mathematics, Function is a relationship between two groups, in which, each element of the first group corresponds to the elements of the second group only once. They shows how a quantity depends on another. For example, the distance a person travels over time spent.

A function is a technique in which each element (x) of a set X is associated with an element of set Y or f(x). The set X is the domain of a function and set Y or f(x) is the codomain.

Each x is the input of a function or variable and each correspondent y is the value of the function or image of x by f.

Answer:

supplementary angle = 60 , complementary angle : none

Final answer:

A supplementary angle of 120 degrees is 60 degrees, and there is no complementary angle for 120 degrees because complementary angles must be less than or equal to 90 degrees.

Explanation:

Finding Supplementary and Complementary Angles

The task is to find the measure of a supplementary angle and a complementary angle for a given angle measure of 120 degrees. To find a supplementary angle, you subtract the given angle from 180 degrees. Thus, the supplementary angle of 120 degrees is 180 - 120 = 60 degrees. On the other hand, a complementary angle adds up to 90 degrees. Since 120 degrees is greater than 90, it is not possible to have a complementary angle to 120 degrees, therefore, we write 'none'. It's important to remember that complementary angles are always less than or equal to 90 degrees and hence, cannot be obtained for angles larger than 90 degrees.

In summary, the supplementary angle to 120 degrees is 60 degrees, and there is no complementary angle for 120 degrees.

Answer:

  564 ft²

Step-by-step explanation:

To account for the extra space between units, we can add 2" to every unit dimension and every box dimension to figure the number of units per box.

Doing that, we find the storage box dimensions (for calculating contents) to be ...

  3 ft 2 in × 4 ft 2 in × 2 ft 2 in = 38 in × 50 in × 26 in

and the unit dimensions to be ...

  (4+2)" = 6" × (6+2)" = 8" × (2+2)" = 4"

A spreadsheet can help with the arithmetic to figure how many units will fit in the box in the different ways they can be arranged. (See attached)

When we say the "packing" is "462", we mean the 4" (first) dimension of the unit is aligned with the 3' (first) dimension of the storage box; the 6" (second) dimension of the unit is aligned with the 4' (second) dimension of the storage box; and the 2" (third) dimension of the unit is aligned with the 2' (third) dimension of the storage box. The "packing" numbers identify the unit dimensions, and their order identifies the corresponding dimension of the storage box.

We can see that three of the four allowed packings result in 216 units being stored in a storage box.

If storage boxes are stacked 4 deep in a 9' space, the 2' dimension must be the vertical dimension, and the floor area of each stack of 4 boxes is 3' × 4' = 12 ft². There are 216×4 = 864 units stored in each 12 ft² area.

If we assume that 2 weeks of production are 80 hours of production, then we need to store 80×500 = 40,000 units. At 864 units per 12 ft² of floor space, we need ceiling(40,000/864) = 47 spaces on the floor for storage boxes. That is ...

  47 × 12 ft² = 564 ft²

of warehouse floor space required for storage.

The answer is:

The x-intercept or roots of the parabola are:

[tex]x_{1}=-5\\x_{2}=-1[/tex]

To solve the problem, we need to find the roots or zeroes of the parabola.

We can find the zeroes of the quadratic equation (parabola) by factoring its equation.

So,we are given the function:

[tex]f(x)=x^{2} +6x+5[/tex]

To factorize the equation, we need to find two numbers which product gives as result the number 5, and its addition gives as result the number "6", these numbers are 5 and 1.

So, rewriting the equation, we have:

[tex]f(x)=x^{2} +6x+5=(x+5)(x+1)=0[/tex]

Therefore, we have that the x-intercept or roots of the parabola are:

[tex]x_{1}=-5\\x_{2}=-1[/tex]

Have a nice day!

Note: I have attached a picture for better understanding.

Answer:

[tex]x = -5\\x = -1[/tex]

Step-by-step explanation:

To find the intercept with the x axis, you must do [tex]f(x) = 0[/tex]

So:

[tex]f(x) = x^2 + 6x + 5 = 0[/tex]

Now you must factor the expression.

To factor the expression you must find two numbers such that when you add them, you obtain 6 and multiplying it will result in 5.

You can verify that these numbers are 5 and 1.

So

[tex]f(x) = (x + 5)(x + 1) = 0[/tex]

Therefore the solutions are

[tex]x = -5\\x = -1[/tex]

Step-by-step explanation:

(cos t) (sec t − cos t)

1 − cos² t

sin² t

The expression cos t(sec t - cos t) simplifies to sin² t, which matches option D.

The student has asked to simplify the expression cos t(sec t − cos t).

To simplify this expression, we start by distributing cos t across the parentheses:

cos t × sec t − cos t ×cos t

1 − cos² t (since cos t × sec t = 1)

1 − (1 − sin² t) (using the Pythagorean identity cos² t + sin² t = 1)

sin² t

Thus, the expression simplifies to sin² t, which corresponds to option D.

Answer:

x = 29.2

Step-by-step explanation:

Given

Perpendicuar=10

Angle=20 degrees

Hypotenuse=x

We will use the trigonometric ratios of right angled triangle to solve this question. Since, we have to find x which is the hypotenuse of the given triangle. So we will use the ratio which involves perpendicular and hypotenuse.

sin⁡ 20=Perpendicular/Hypotenuse

sin⁡ 20=10/x

x=10/sin ⁡20  

x=10/0.3420

x=29.239

Rounding off to nearest tenth.

x=29.2

For this case we have the following system of equations:

[tex]y = x ^ 2-4x + 3\\y = -x + 3[/tex]

Matching we have:

[tex]x ^ 2-4x + 3 = -x + 3\\x ^ 2-4x + x + 3-3 = 0\\x ^ 2-3x = 0[/tex]

We solve by means of

[tex]x = \frac {-b \pm \sqrt {b ^ 2-4 (a) (c)}} {2a}[/tex]

Where:

[tex]a = 1\\b = -3\\c = 0[/tex]

Substituting:

[tex]x = \frac {- (- 3) \pm \sqrt {(- 3) ^ 2-4 (1) (0)}} {2 (1)}\\x = \frac {3 \pm \sqrt {9}} {2}\\x = \frac {3 \pm3} {2}[/tex]

Finally, the roots are:

[tex]x_ {1} = \frac {3-3} {2} = 0\\x_ {2} = \frac {3 + 3} {2} = \frac {6} {2} = 3[/tex]

Answer:

[tex]x_ {1} = 0\\x_ {2} = 3[/tex]

Step-by-step explanation:

The bottles are cylindrical.  The volume of a cylinder is:

V = πr²h

where r is the radius (half the diameter) and h is the height.

The bottles are similar, so we can write a proportion to find the height of the smaller bottle:

3/10 = 1.5/h

h = 5

The volume of the big bottle is:

V = π(3/2)²(10)

V ≈ 70.7

The volume of the small bottle is:

V = π(1.5/2)²(5)

V ≈ 8.8

Answer:

nonagon: 140°

100-gon: 176.4°

Step-by-step explanation:

A regular polygon is one that has all sides the same length and all internal angles the same measure. A "nonagon" has nine (9) sides. An image of one is attached. There are some interesting relationships among the angles shown.

The figure can be divided into 9 congruent triangles. Each has a vertex at the center of the figure, and the other two vertices are each end of one side. The central angle (40°) is the supplement of the interior angle at each vertex of the nonagon (140°). Obviously, the central angles sum to 360° (one full circle), so each one has a measure that is 360° divided by the number of sides:

360°/9 = 40°

So, we can figure the interior angle (at the vertex) by subtracting from 180° the value of 360° divided by the number of sides.

For the 100-gon, with 100 sides, the interior angle will be ...

180° -360°/100 = 180° -3.6° = 176.4°

Final answer:

The interior angle of a regular nonagon is 140°, and for a regular 100-gon, it's 176.4°.

Explanation:

To find the interior angles of a regular polygon, we use the formula: (n - 2) × 180°, where n is the number of sides of the polygon. This formula gives us the sum of all interior angles of the polygon.

To find the measure of one interior angle in a regular polygon (where all angles are equal), we divide this sum by the number of sides.

Interior Angle of a Regular Nonagon:

A nonagon has 9 sides. Using our formula:

Interior Angle of a Regular 100-gon:

A 100-gon has 100 sides. Following the same process:

Therefore, each interior angle of a regular nonagon is 140°, and each interior angle of a regular 100-gon is 176.4°.

ANSWER

The discriminant is 384. Because the discriminant is greater than 0 and is not a perfect square, the two roots are real and irrational.

EXPLANATION

The given quadratic equation is:

[tex] - 3 {x}^{2} - 18x + 5 = 0[/tex]

We compare this equation to:

[tex]a {x}^{2} + bx + c = 0[/tex]

We have a=-3,b=-18, and c=5.

The discriminant of a quadratic equation is calculated using the formula:

[tex]D=b^{2} - 4ac[/tex]

We plug in the values to obtain:

[tex]D= {( - 18)}^{2} - 4( - 3)(5)[/tex]

[tex]D= 324 + 60[/tex]

Simplify:

[tex]D= 384[/tex]

The discriminant is greater than zero, hence there are two distinct real roots.

Since 384 is not a perfect square, the roots are irrational.

ANSWER

The curve is a parabola with a vertex at left parenthesis 3 comma negative 4 right parenthesis and is traced from left to right for increasing values of t.

EXPLANATION

The given curve is defined parametrically as;

[tex]x = 3+ t[/tex]

[tex]y = {t}^{2} - 4[/tex]

We need to eliminate the parameter by making t the subject in the first equation and substitute into the second equation.

[tex]t = x - 3[/tex]

[tex]y = {(x - 3)}^{2} - 4[/tex]

This is a parabola that has its vertex at (3,-4).

This parabola opens upwards.

The correct description is a parabola with a vertex at (-3, -4) and, because x increases linearly with t, it is traced from left to right as t increases. This corresponds to option 3.

The student's question involves finding the description of a curve represented by parametric equations x = -3 + t and y = t^2 - 4. Considering the equation for y which is a second-order polynomial in t, it indicates that the graph is a parabola. The presence of t^2 indicates the parabola opens upwards as the coefficient is positive. If we were to eliminate t from the parametric equations, the resultant equation would still describe this parabola.

To analyze the vertex, the standard form for a parabola's equation is y = ax^2 + bx + c. Given that y = t^2 - 4 has a constant term of -4, this suggests the vertex's y-coordinate is -4. For the x-coordinate of the vertex, we must consider the constant -3 in the x equation, which adjusts the x-coordinate of the vertex. Since the parametric equation for x alone does not yield an obvious vertex, we realize that the parabola is shifted from the origin, and the -3 signifies a leftward shift from the y-axis.

Therefore, The correct description is a parabola with a vertex at (-3, -4) and, because x increases linearly with t, it is traced from left to right as t increases. This corresponds to option 3.
