Answer:

Step-by-step explanation:

The last (fourth) graph is that of the parent function y = √x.  The negative sign in front of √x leads to reflection of this parent function graph in the x-axis.  Thus, the correct graph of f(x) = -√x is the first one.

The new coordinates of the figure is :

A=( 1,5)  B= (-4,5)  C= (-4,8)

A point on a plane can be subject to transformations. Examples of transformations that can be done on points are translations, reflections, or rotations about a point. These transformations are also observed algebraically, in which functions on the coordinates are applied.

Recall that if (x, y) is a point on the plane, reflecting it across the y-axis means that the x-coordinate is negated:

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

The coordinates of the figure is

A = (-1,5)

B = (4, 5)

C = (4, 8)

The new coordinates of the figure is :

A=( 1,5)  B= (-4,5)  C= (-4,8)

This means that the first coordinate is changed, and the y-coordinate is left as is.

Therefore, it is the y-coordinate that stays the same when reflected across the y-axis.

A (1, 5), B (-4, 5), C (-4, 8) are the new coordinates of the figure aboge if it is reflected over the y axis.

In the realm of plane geometry, various transformations can be applied to points, facilitating a means of altering their positions or orientations. These transformations include translations, reflections, and rotations, all of which have algebraic representations.

When reflecting a point across the y-axis, as denoted by the transformation (x, y) => (-x, y), the x-coordinate is negated while the y-coordinate remains unaffected.

This can be observed in the coordinates of the figure:

A (-1, 5)

B (4, 5)

C (4, 8)

After the reflection, the new coordinates become:

A (1, 5)

B (-4, 5)

C (-4, 8)

It is evident that the reflection operation results in the change of the sign of the x-coordinate while leaving the y-coordinate unaltered. Consequently, the y-coordinate remains the same when a point is reflected across the y-axis, illustrating a fundamental property of this geometric transformation.

Answer:

C

Step-by-step explanation:

You are making a couple of assumptions. The first is that since the given has units of m/s that requires an acceleration based in m/s^2. That eliminates choices A and B. 16 is usually associated with f/s^2

Second, you are assuming 42m/s is positive and the acceleration due to gravity is negative. It doesn't matter as long as they are opposite.

Third, you are assuming that 42 m/s is the vertical acceleration.  If it is not then some sort of trigonometry is needed. Since your choices don't offer trig then this assumption must be taken care of.

So the correct answer is C.

Answer:

Not inverse of each other

Domain : [-∞,0) U (0,5) U (5,∞]

Step-by-step explanation:

Given in the question two functions

f(x)=1/x-5

g(x)=5x-1/x

To find that each of them are inverse of each other we will use composition

[tex]\frac{1}{\frac{5x-1}{x}-5 }[/tex]

take LCM

[tex]\frac{1}{\frac{5x-1-5x}{x}}[/tex]

5x will be cancel

[tex]\frac{1}{\frac{-1}{x}}[/tex]

1 ÷ (-1/x)

1 × (-x/1)

-x

Now,

[tex]\frac{5\frac{1}{x-5} -1}{\frac{1}{x-5}}[/tex]

[tex]\frac{5}{x-5} -1}[/tex] × [tex]5-x[/tex]

[tex]\frac{5-x+5}{x-5} * (x-5)[/tex]

10-x

As it ended up with different answers, so f(x) and g(x) are not inverse of each other

The domain are all the possible x-values of function except x ≠ 0 and x ≠ 5

We can conclude that the domain of the composition function is

Domain : [-∞,0) U (0,5) U (5,∞]

To prove whether or not the functions f(x) = 1/(x-5) and g(x) = (5x-1)/x are inverses of each other, we need to show that their compositions result in the identity function. We also need to find the domain of the compositions f(g(x)) and g(f(x)).

To prove whether or not the functions f(x) = 1/(x-5) and g(x) = (5x-1)/x are inverses of each other, we need to show that their compositions result in the identity function. Let's start by finding the composition f(g(x)):

Now, we need to find the composition g(f(x)): g(f(x)) = g(1/(x-5))

Follow the same steps as above to simplify g(f(x)) as a function of x. If the compositions f(g(x)) and g(f(x)) both result in the identity function, then the functions f(x) and g(x) are inverses of each other.

To express the domain of the compositions f(g(x)) and g(f(x)), we need to consider the restrictions on the domains of the individual functions. The domain of f(g(x)) will be the values of x for which (5x-1)/x is defined, and the domain of g(f(x)) will be the values of x for which 1/(x-5) is defined.

Answer:

x = 75 degrees

Step-by-step explanation:

155 and the angle next to it makes 180 degrees

To find the missing angle take 180 and subtract 155

180 - 155 = 25

All the angles in the upper triangle are 25, 80 and x

To find x add 80 and 25

80 + 25 = 105

A triangle equals 180 degrees so subtract 105 from 180 to get x

180 - 105 = 75

The equation of the hyperbola in standard form is

[tex]\frac{y^{2}}{100}-\frac{4x^{2}}{625}=1[/tex]

Step-by-step explanation:

* We will take about the standard form equation of the hyperbola

- If the given coordinates of the vertices (0 , a) and (0 , -a)

∴ The transverse axis is the y-axis. (because x = 0)

- If the given asymptotes at y = ± (b/a) x

∴  Use the standard form  ⇒ y²/a² - x²/b² = 1

* Lets use this to solve our problem

∵ The vertices are (0 , 10) and (0 , -10)

∴ a = ±10

∴ a² = 100

∵ The asymptotes at y = ± 5/4 x

∴ ± 5/4 = ± b/a

∵ a = ± 10

∴ ± 5/4 = ± b/10 ⇒ using cross multiplication

∴± (4b) = ± (5 × 10) = ± 50 ⇒ divide both sides by 4

∴ b = ± 25/2

∴ b² = 625/4

* Now Lets write the equation

* y²/100 - x²/(625/4) = 1

∵ x² ÷ 625/4 = x² × 4/625 = (4x²/625)

∴ y²/100 - 4x²/625 = 1

* The equation of the hyperbola in standard form is

  [tex]\frac{y^{2}}{100}-\frac{4x^{2}}{625}=1[/tex]

Answer: Independent Variable

Step-by-step explanation:

The independent (or manipulated) variable is something that the experimenter purposely changes or varies over the course of the investigation. The dependent (or responding) variable is the one that is observed and likely changes in response to the independent variable.

Answer:

The standard form of the equation is y = 2x^2 + 16x + 25

Step-by-step explanation:

To find the standard form, first square the parenthesis.

y = 2(x + 4)^2 - 7

y = 2(x^2 + -8x + 16) - 7

Now distribute the 2

y = 2(x^2 + 8x + 16) - 7

y = 2x^2 + 16x + 32 - 7

Now combine like terms

y = 2x^2 + 16x + 32 - 7

y = 2x^2 + 16x + 25

x = 20 feet, y = 40 feet

Step-by-step explanation:

See attached photo for solution

The length of the brick wall is 20 ft and the length of an adjacent side is 40 ft and this can be determined by forming the linear equation in two variables.

Given :

Let 'x' be the length of the brick wall and 'y' be the length of an adjacent side in feet. Then the area of the garden is:

xy = 800    --- (1)

The perimeter of the rectangular garden will be:

Perimeter = 24x + 8x +2(8)y    ---- (2)

Now, solve equation (1) for y.

[tex]y = \dfrac{800}{x}[/tex]   --- (3)

Now, put the value of 'y' in equation (2).

[tex]\rm P=32x+16\times \dfrac{800}{x}[/tex]

Now, for minimizing cost differentiate the perimeter with respect to 'x'.

[tex]\rm P'=32-16\times \dfrac{800}{x^2}[/tex]

Now, equate the above equation to zero.

[tex]0=32-16\times \dfrac{800}{x^2}[/tex]

[tex]\dfrac{800}{2}={x^2}[/tex]

x = 20

Now, put the value of 'x' in the equation (3).

The value of X is 112° and The value of Y is 68°

Answer:

Angle y: 68°

Angle x: 112°

Step-by-step explanation:

When you are dealing with two sets of parallel lines where one set intercepts the other, angles are always the same as the parallel line's angle. In this example

∡PM = 68° = ∡y°

Seeing that we now know that y is 68° and q is a straight line (Straight Lines have an angle of 180°) we can subtract 68° from 180° in order to get the degree of the angle x.

180° - 68° = 112°

Now we know that angle y is 68° and angle x is 112°

Step-by-step explanation:

Employees need to stock at least 42 each day for a whole week or work. (5 days) so wee need to find how much they need to stock in a week.

42 x 5 = 210.

So They need to stock 210. Employee A has already stocked 185. so we need to take 185  from 210 to see how MORE he needs to stock.

210 - 185 = 25.

25.

Hope this helped! Please mark as brainliest! THanks!

In order to be able to make the goal that was set for the employee, the employee would have to re-stock 25 products.

The worker is supposed to stack an average of 42 products from Monday to Friday which is 5 days.

Technically speaking, in every one of those 5 days, 42 products should be stocked. The total for the week is therefore:

= 5 days x Number of products stocked per day

= 5 x 42

= 210 products

The worker has stocked 210 products already and so is left with:

= Number to be stocked - Number already stocked

= 210 - 185

= 25 products

In conclusion, the worker still has to re-stock 25 products.
