Identify the graph of 4x^2+5y^2=20 for T(5,-6) and write an equation of the translated or rotated graph in general form..

ANSWER: 15.5 units^2

The system has two solutions: [tex]\( (2, -2) \) and \( (-1, 4) \),[/tex] found by solving their simultaneous equations.

let's solve the system step by step:

Given the system of equations:

[tex]1. \( y = -2x + 2 \)\\2. \( y = x^2 - 3x \)[/tex]

We want to find the values of [tex]\( x \) and \( y \)[/tex] that satisfy both equations simultaneously.

First, we set the equations equal to each other since they both equal [tex]\( y \):[/tex]

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

Now, let's rearrange this equation to get a quadratic equation:

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

Now, we can use the quadratic formula to solve for [tex]\( x \):[/tex]

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

where [tex]\( a = 1 \), \( b = -1 \), and \( c = -2 \).[/tex]

[tex]\[ x = \frac{{-(-1) \pm \sqrt{{(-1)^2 - 4(1)(-2)}}}}{{2(1)}} \]\[ x = \frac{{1 \pm \sqrt{{1 + 8}}}}{2} \]\[ x = \frac{{1 \pm \sqrt{9}}}{2} \]\[ x = \frac{{1 \pm 3}}{2} \][/tex]

So, we have two potential values for [tex]\( x \): \( x = 2 \) and \( x = -1 \).[/tex]

Now, let's find the corresponding [tex]\( y \)[/tex] values for each [tex]\( x \)[/tex] value using either of the original equations:

For [tex]\( x = 2 \):[/tex]

[tex]\[ y = -2(2) + 2 = -4 + 2 = -2 \][/tex]

For [tex]\( x = -1 \):[/tex]

[tex]\[ y = -2(-1) + 2 = 2 + 2 = 4 \][/tex]

So, we have two solutions for the system:[tex]\( (2, -2) \) and \( (-1, 4) \).[/tex] Therefore, the system has 2 solutions.

Answer: option c.

Step-by-step explanation:

 To solve the given exercise and write the expression as a single logarithm, you must keep on mind the following properties:

[tex]m*log(a)=log(a)^m[/tex]

[tex]log(a)-log(b)=log(\frac{a}{b})[/tex]

Therefore, by applying the properties shown above, you can rewrite the expression given, as following:

[tex]2logx-6log(x-9)=logx^2-log(x-9)^6=log(\frac{x^2}{(x-9)^6})[/tex]

Then as you can see, the answer is the option c.

Answer:

Area_lawn = 393.75 π ft^2

Step-by-step explanation:

Maximum radius : 30 feet

Minimum radius:  30 feet - 0.25*(30feet)  =  22.5 feet

(25 percent reduction)

To find the area of lawn that can be watered, we just need to calculate the area for the maximum radius and the minimum radius, and then subtract them.

Since the sprinklers have a circular area:

Area = π*radius^2

Max area  = π*(30 ft)^2 = 900π ft^2

Min area  = π*(22.5 ft)^2 = 506.25π ft^2

Maximum area of lawn that can be watered by the sprinkler:

Area_lawn = Max area - Min area = 900π ft^2 -506.25π ft^2

Area_lawn = 393.75 π ft^2

Answer:

1,590.4 sq ft

Step-by-step explanation:

The transformed parallelogram P'Q'R'S' is smaller than the original parallelogram PQRS, due to a scale factor of less than 1 (0.75) being applied in this dilation.

The given transformation (x, y) → (0.75x, 0.75y), the scale factor is 0.75, indicating a reduction in size. This means that the transformed parallelogram P'Q'R'S' is smaller than the original PQRS. The scale factor of 0.75 signifies that both the x and y coordinates of every point in the original parallelogram are multiplied by 0.75, leading to a proportional reduction in dimensions. Therefore, option B) stating that Parallelogram P'Q'R'S' is smaller than parallelogram PQRS due to the scale factor being less than 1, accurately describes the transformation, illustrating the diminished size of the transformed figure in comparison to the original one.

https://brainly.com/question/29811168

#SPJ12

The correct answer is B: Parallelogram P'Q'R'S' is smaller than parallelogram PQRS because the dilation scale factor is 0.75, which is less than 1.

The question asks about the effect of a given dilation on a geometric figure, specifically a parallelogram named PQRS, which is transformed into parallelogram P'Q'R'S'.

This transformation is performed using the dilation rule (x, y) → (0.75x, 0.75y), which indicates that every point on the original parallelogram is multiplied by the scale factor of 0.75 when creating the new parallelogram.

Since the scale factor is less than 1, each coordinate is reduced to 75% of its original value, resulting in a figure that is proportionally smaller than the original.

Therefore, the correct statement about the relationship between the original parallelogram PQRS and the dilated parallelogram P'Q'R'S' is Option B: Parallelogram P'Q'R'S' is smaller than parallelogram PQRS, because the scale factor is less than 1.

Answer:

16 feet

Step-by-step explanation:

Since the scale is 3 in : 4 ft, the model car is 16 ft.

To find the actual length of a model car given a scale of 3 inches : 4 feet with the model car being 12 inches long, set up a proportion to calculate the actual car length, which is 16 feet.

A scale of 3 inches : 4 feet means that for every 3 inches on the model car, the actual car is 4 feet long. Given that the model car is 12 inches long, you can set up a proportion:

Solving for x, you get the actual length of the car to be 16 feet.

The height of a triangle with an area of 3.6 cm² and a base of 6 cm is calculated using the area formula, resulting in a height of 1.2 cm.

To find the height of a triangle when the area and base are known, we use the formula for the area of a triangle, which is area = 1/2 × base × height. The given area is 3.6 cm2, and the base is 6 cm. Rearranging the formula to solve for the height, we get height = (2 × area) / base.

Plugging the values in, we get height = (2 × 3.6 cm2) / 6 cm = 7.2 cm2 / 6 cm = 1.2 cm.

Thus, the height of the triangle is 1.2 cm, which corresponds to option B.

The height of a triangle with an area of 3.6 cm² and a base of 6 cm is found by rearranging the formula for the area of a triangle. The calculated height comes out to be 1.2 cm.

To find the height of a triangle given the area and base, we can use the formula for the area of a triangle which is Area = (1/2) × base × height. In this case, the area is 3.6 cm² and the base is 6 cm.

Rearranging the area formula to find the height, we get height = (2 × Area) / base. Plugging in the values, we have:

height = (2 × 3.6 cm²) / 6 cm = 7.2 cm² / 6 cm = 1.2 cm.

Therefore, the correct answer to the question is B. 1.2 cm.

Answer:

So the answer is (3, 0) on a graph.

Step-by-step explanation:

What I use is a graphing calculator. It helps tremendously. It is called desmos.com. Hope this helps.

Answer:

The given function is

[tex]y=log(x-2)[/tex]

To graph any function, we just have to five arbitrary values to x-variable, and see the y-values that gives to formed coordinate pairs to graph them then.

In this case, the table that shows these values is gonna be

X       Y

2.5   -0.3

3        0

3.5    0.2

4       0.3

4.5 0.4

Notice that we started from [tex]x=2.5[/tex]. The reason is beacuse the given logarithmic function is not defined for values equal or lower than 2, when taht happens, the function becoms undetermined. This means the domain of the given function has to be restricted to [tex]D= (x>2)[/tex], otherwise the function won't be defined.

Next, we evalute the function for each case.

[tex]x=2.5[/tex]

[tex]y=log(x-2)=log(2.5-2)=log(0.5) \approx -0.3[/tex]

[tex]x=3\\y=log(x-2)=log(3-2)=log(1)=0[/tex]

[tex]x=3.5\\y=log(x-2)=log(3.5-2)=log(1.5) \approx 0.2[/tex]

[tex]x=4\\y=log(x-2)=log(4-2)=log(2) \approx 0.3[/tex]

[tex]x=4.5\\y=log(x-2)=log(4.5-2)=log(2.5) \approx 0.4[/tex]

When you have the table completed, you proceed to graph each coordinate.

In this case, the graph of the logarithmic function would be as the image attached. That's all the process to graph the function.

(In the graph, you can observe how fast the function drops when is near to x=2, that's the undetermination behaviour we talk about lines above).

Answer:

[tex]a_n=-12-4(n-1)[/tex]

Step-by-step explanation:

The given sequence is

-12,-16,-20...

The first term of this sequence is [tex]a_1=-12[/tex].

The common difference is

[tex]d=-16--12[/tex]

[tex]d=-16+12=-4[/tex]

The nth term of this arithmetic sequence is;

[tex]a_n=a_1+d(n-1)[/tex]

We substitute the values for the first term and the common difference to obtain;

[tex]a_n=-12-4(n-1)[/tex]

Answer:

[tex]a_{n} = -12-4(n-1)[/tex]

Step-by-step explanation:

We have given a arithmetic sequence.

-12,-16,-20,...

We have to find formula for a given sequence.

The general formula for nth term of sequence is :

[tex]a_{n} = a_{1}+d(n-1)[/tex]

In given sequence,

[tex]a_{1} = -12[/tex]

d is the common difference between consecutive terms.

d = -16-(-12)  = -16+12

d = -4

Putting given values in formula, we have

[tex]a_{n} = -12-4(n-1)[/tex] which is the answer.

After calculating the perimeters, both the square and the rectangle have the same perimeter of 32 inches when the square has each side measuring 8 inches and the rectangle has dimensions of 6 inches by 10 inches.

To determine which shape has the greater perimeter, calculate the perimeter of both the square and the rectangle. The formula for the perimeter of a square is 4 × side length, and the formula for the perimeter of a rectangle is 2 × (length + width).

For the square with each side measuring 8 inches, its perimeter is 4 × 8 = 32 inches.

For the rectangle with a width of 6 inches and a length of 10 inches, its perimeter is 2 × (10 + 6) = 2 × 16 = 32 inches.

Therefore, both the square and the rectangle have the same perimeter of 32 inches.

Answer:

Picture 1 is the answer.

Step-by-step explanation:

The expression states that the absolute value of a number x , is equal to the number 7. Absolute Values have an 2 inputs for every output (except for 0), the negative and positive inputs both output the same positive number.

Example: abs(-5) = abs(5) = 5

The Absolute value of -5 and 5 both output 5. Therefore, there are two possible x values for the answer to be 7 and those values are -7 and 7. Since these are the only possible values they would be represented on a number line as closed dots.

The only picture with closed dots on both -7 and 7 is picture 1. So that is the answer.

Answer:

The state with the second lowest population has the lowest population density.

Step-by-step explanation:

The state with the second lowest population has the lowest population density.

State B has the second lowest population, and it has the lowest population distance considering it has a substantial amount of area compared to other states, yet 1, 333, 089 people, in comparison it therefore as the lowest population density.

The statement "The state with the second-lowest population has the lowest population density." is true.

The population density can be found by dividing the total population of an area by the area.

We must calculate the population densities of all the states to determine which state has the highest density.

This can be done as shown below:

State A:

Population density = Population/Area

= 1,055,173/2,677

= 394.162

State B:

Population density = Population/Area

= 1,333,089/36,418

= 36.605

State C:

Population density = Population/Area

= 3,596,677/5,543

= 648.87

State D:

Population density = Population/Area

= 6,745,408/10,555

= 639.072

We can see that the state with the second-lowest population has the lowest population density.

Therefore, we have found that the statement "The state with the second-lowest population has the lowest population density." is true. The correct answer is option B.

Step-by-step explanation:

Diagram

Let's look at the diagram for a moment.

The 8 in line has been extended.

The dashed line is the height associated with the 8 inch line

The dashed line and the 8 inch line's extension meets at right angles.

Discussion

Normally you would take the 8 inch line and the height and divide their product by 2. You don't have the height. So you have to somehow get an expression for it.

The 81o angle is the supplement of the 99o angle. If you take the sine of both of them the sines are equal.

h = sin(81) * 14.2 because

sin(81) = opposite / hypotenuse.

opposite = hypotenuse * sin(81)

opposite = height = hypotenuse* sin(81)

height = 14.2 * sin(81)

Now we can find the area

Area

Area = height * base

base = 8

height = 14.2 * sin(81)

Area = 1/2 * 8 * 14.2 * sin(81)

Area = 56.1
