Under T, the point (0,2) gets mapped to (3,0). T -1 (x, y)


(x + 3, y - 2)

(x - 3, y + 2)

(x - 3, y - 2)

Answer:

(- 1, 4)

Step-by-step explanation:

The line x = 1 is a vertical line.

The point P(3, 4) is 2 units to the right of x = 1 ( 3 - 1 = 2 )

Hence the reflection will be 2 units to the left of x = 1, that is  (1 - 2)

P'(- 1, 4)

The reflection of point P(3, 4) about the vertical line x = 1 is P'(-2, 4).

Reflection is a transformation that flips a figure over a line or a plane. It is a type of symmetry transformation that maintains the same shape and size of the object but changes its orientation with respect to the line or plane of reflection.

Given: Point P(3, 4).

The line x = 1 is a vertical line.

Now, let's find the reflection of point P(3, 4) about the vertical line x = 1:

To reflect a point about a vertical line, we reverse the sign of the x-coordinate while keeping the y-coordinate the same.

So, the reflection of P(3, 4) will be (-2, 4).

Hence, the reflection of point P(3, 4) is P'(-2, 4).

Answer:

Explanation:

For the first question, the mathematical (statistical, to be more precise) definition of a event that is impossible is that its probability is zero.

There are two extremes when you talk about probability: 0 and 1. 0 means that the event cannot occur in any way, while 1 is that the event is certain (it cannot not happen).

An example of an event with probability 0 is: men born in the Sun. This is an impossible event, and so there is no chance (probability 0) to find a man born in the Sun.

For the second question, when you deal with empirical results, this is with an experiment, the fact of having a probability zero as result of approximations does not make that an event be impossible; the event is unlikely (if the experiments were carried out properly) but yet it can happen.

For example, say you put 1,000 ballots in a bag with the number 3, together with 1 ballot with the number 9. Then, you perform the experiment of drawing a ballot 2,000 times. Suppose you draw the ballot with the number 9 two times. In that case, your approximated experimental probability of drawing a 9 will be 2 /2,000 = 0.001. Which you could round to 0.00. That may be valid but it cannot be taken as that the event of drawing the ballot with the number 9 is impossible, it is just unlikely.

Answer:

  b.  10

Step-by-step explanation:

For the most part, these are problems in addition. The measures of the different angles add up according to the relationships given in the problem statement.

From the picture, you can tell that ∠JKN is the sum of ∠1 and ∠2, which are said to be equal (congruent). That is, ∠1 has a measure that is half of that of ∠JKN.

Since ∠JKN is a right angle, 90°, and the measure of ∠1 is half that, m∠1 is 45°.

So, to find t, we equate the given expression for m∠1 to 45 and solve.

  4t +5 = 45

  4t = 40 . . . . . subtract 5

  t = 10 . . . . . . . divide by 4 . . . . . matches answer choice B

Answer:

(1,6)

Step-by-step explanation:

In this question, the point (1,2) is first reflected on the line y=0 then followed by line y=2

In the first reflection, y=0, the line is the x-axis, so the point (1,2) is reflected on the x-axis. The law here is that reflection of a point (x,y) on the x-axis, will result to an image of (x,-y)

The point is (1,2), its image will be (1,-2)

The new image (1, -2) is then reflected on the line y=2 but you should be aware that the x-coordinate will remain the same, but the y-coordinate will change. This is to say that the y coordinate value will shift the same number of units above the line y=2 as it is below the line y=2

Point (1,-2) reflected on line y=2 will result to an image (1,6). The x-coordinate value has remained the same, where as the y coordinate value has shifted 4 units above the line y=2 because it was 4 units below the line y=2.

Final image will be (1,6)

Final answer:

The spinner is half RED and WHITE, and the other half is BLUE and GREEN. With 1/6 of it being GREEN, the remaining fraction 1/3 of the spinner is BLUE.

Explanation:

To determine how much is BLUE on the mystery spinner, we must calculate the portions of each color. We know that the spinner is 50% RED and WHITE combined and the remainder is BLUE and GREEN. Since 1/6 of the spinner is GREEN, we have to find out what fraction is left for BLUE.

Firstly, we calculate what 50% is in fraction form, which is 1/2 of the spinner. Now, knowing that 1/6 of the spinner is GREEN, we subtract the GREEN fraction from the half not covered by RED and WHITE:

1/2 (portion of BLUE and GREEN) - 1/6 (portion of GREEN) = (3/6 - 1/6) = 2/6, which simplifies to 1/3.

Therefore, 1/3 of the spinner is BLUE.

Answer: Lena eats 1/4 of the whole bar

Step-by-step explanation:

Half of the bar is 50. A full bar would be 100%. If Phillip has half, amd Lena eats half of that half, she eats 0.25 out of 0.5. 0.5 is half of the whole bar, so 0.5×0.5 is 1, and if lena ate 0.25 of 1, that is 1/4.

In the context of mathematical geometry, if 'A⊥Y and X || Y', it means that A is perpendicular to Y and X is parallel to Y. In such a scenario, A would also be perpendicular to X.

In mathematical terms, the symbols used in this question represent geometric relationships. Here, 'A⊥Y' means that A is perpendicular to Y, meaning A intersects with Y at a right angle (90 degrees). 'X || Y' signifies that X and Y are parallel, meaning they are in the same plane never intersect or meet, regardless of how far extended.

When it is given 'A⊥Y and X || Y', this suggests a specific geometric condition. In such a case, the vector A (or line/segment) is perpendicular to the vector Y. Also, the Vector X is parallel to Y. From these conditions, if one line is perpendicular to a second line, and a third line is parallel to the second line, then the first and third lines are also perpendicular to each other. Therefore, the conclusion in this case would be 'A is perpendicular to X' or 'A⊥X'.

Answer:

  [tex]\dfrac{r_s}{r_r}\approx 6.3346[/tex]

Step-by-step explanation:

The ratio of the radii is the square root of the ratio of the areas:

  [tex]\dfrac{r_s}{r_r}=\sqrt{\dfrac{22680}{565.2}}\approx 6.3346[/tex]

The radius of sphere s is about 6.3346 times as large as the radius of sphere r.

To determine the ratio of the sizes of the radii of the two spheres based on their surface areas, you can use the ratios of the square roots of the surface areas. Using this method, the radius of Sphere S is found to be roughly 8 times larger than Sphere R

The subject topic of this question is related to geometry, specifically looking at the relationship between the surface areas of two spheres and their respective radii. Given that the surface area (SA) of a sphere is given by the formula SA=4πr², you can set up a ratio for the radii.

The square roots of the ratios of the surface areas of the spheres will give us the ratio of the radii. In other words, sqrt(SA of sphere S/ SA of sphere R) = ratio of the radii. Substituting the given values, we get sqrt(22680/565.2) which approximately equals to 8.

Therefore, the radius of Sphere S is approximately 8 times larger than Sphere R.

Answer:

B. infinite solutions along a line

Step-by-step explanation:

The matrix is equivalent to the equations ...

x = 2

y = 9

0z = 0 . . . . . . true for any z

This tells you the solutions are ...

(x, y, z) = (2, 9, z)

This defines a line parallel to the z-axis.

First you must know that the sides 2x and x + 8 are equal to each other and sides x and 3x - 16 are equal to each other.

This means you can make a formula like so:

2x = x + 8

and

x = 3x - 16

Now you may solve for x for both of them (you should get the same answer for both x's)

2x - x = (x - x) + 8

x = 8

and

x - 3x = (3x - 3x) - 16

-2x = -16

-2x/-2 = -16/-2

x = 8

To find the length of each side just replace x with 8!

Answer:

  "halfway between"

Step-by-step explanation:

The zero crossings are symmetrical about the line of symmetry, which is a vertical line through the vertex. The x-coordinate of the vertex s the average of the two x-intercepts, so lies between them--exactly halfway between them.

Answer:

Between

Step-by-step explanation:

The Vertex is a point where two or more curve meets. In the case of a quadratic equation, the vertex is at the minimum point (if a is positive) or at the maximum point (if a is negative).

When the graph of a quadratic function crosses the x-axis twice, the x-coordinate of the vertex lies between the two x-intercepts.

Note that the two x-intercepts are the roots of the quadratic function.

If you translate circle 1 with the vector (6,-4), the center will become

[tex](-4,5)+(6,-4) = (-4+6,5-4)=(2,1)[/tex]

So, circles 1 and 2 are now concentric. The radii are, respectively, 2 and 6. This means that, if we dilate circle 1 with a scale factor of 3, its radius will become 6 as well.

After this two transformations, both circles will have center (2,1) and radius 6.

The transformation rule is (x+6, y-4).

We dilate by a factor of 3.

A circle is a perfectly round shape meaning any point around its curve is the same distance from its central point called the center

Firstly we need to shift the center.

Step-by-step explanation:

1/20 = 5/100 = 5%

If that value is cut in half, it becomes ...

(1/2)×5% = 2.5%

Answer:

The correct option is 4) 2.5%

Step-by-step explanation:

Consider the provided information.

One of every 20 customers reports poor customer service on your company’s customer satisfaction survey.

First find the 1 is how much percent of 20.

[tex]\frac{1}{20}\times 100=1\times 5=5\%[/tex]

That means 5% of customers reports for poor customer services.

It is given that, You have just created a new process that should cut the number of poor customer service complaints in half.

Previously 5% of customers was not satisfy with the customer services, now only half of it not satisfy the customer service.

[tex]\frac{1}{2}\times 5\%=2.5\%[/tex]

Hence, the correct option is 4) 2.5%

Looks like [tex]f(x,y)=x^2+y^2-x^2y+7[/tex].

[tex]f_x=2x-2xy=0\implies2x(1-y)=0\implies x=0\text{ or }y=1[/tex]

[tex]f_y=2y-x^2=0\implies2y=x^2[/tex]

The latter two critical points occur outside of [tex]D[/tex] since [tex]|\pm\sqrt2|>1[/tex] so we ignore those points.

The Hessian matrix for this function is

[tex]H(x,y)=\begin{bmatrix}f_{xx}&f_{xy}\\f_{yx}&f_{yy}\end{bmatrix}=\begin{bmatrix}2-2y&-2x\\-2x&2\end{bmatrix}[/tex]

The value of its determinant at (0, 0) is [tex]\det H(0,0)=4>0[/tex], which means a minimum occurs at the point, and we have [tex]f(0,0)=7[/tex].

Now consider each boundary:

[tex]f(1,y)=8-y+y^2=\left(y-\dfrac12\right)^2+\dfrac{31}4[/tex]

which has 3 extreme values over the interval [tex]-1\le y\le1[/tex] of 31/4 = 7.75 at the point (1, 1/2); 8 at (1, 1); and 10 at (1, -1).

[tex]f(-1,y)=8-y+y^2[/tex]

and we get the same extrema as in the previous case: 8 at (-1, 1), and 10 at (-1, -1).

[tex]f(x,1)=8[/tex]

which doesn't tell us about anything we don't already know (namely that 8 is an extreme value).

[tex]f(x,-1)=2x^2+8[/tex]

which has 3 extreme values, but the previous cases already include them.

Hence [tex]f(x,y)[/tex] has absolute maxima of 10 at the points (1, -1) and (-1, -1) and an absolute minimum of 0 at (0, 0).

The function must first have its partial derivatives set to zero to find its critical points. Also, considering the given domain's boundaries with Lagrange multipliers can establish the function's maximum and minimum points.

This function is a multivariable function and to find its extreme values within a specified domain you would use multivariable calculus methods. For the given function f(x, y) = x2 + y2 − x2y + 7, we first find its critical points by setting its partial derivatives equal to zero and then solve for x and y. Additionally, we need to consider the boundaries of the set {|x| ≤ 1, |y| ≤ 1} by using the method of Lagrange multipliers. The extreme values are obtained at the critical points within the domain, including the boundary.

Step-by-step explanation:

Using the formula for calculating interest (I) which is PRT, you substitute the given values for principal (P), rate (R), and time (T) respectively. First, calculate the product of principal P and rate R, then multiply this result by the time (T). Hence, the estimated interest is $103,396.54.

The formula for calculating interest (I) is I = PRT. In your case, the principal (P) is $49,236.45, the rate (R) is 105% or 1.05 (we use decimal form for this calculation), and the time (T) is 2 years. To calculate interest, we substitute these values into the formula as follows:

I = $49,236.45 * 1.05 * 2

First, calculate the product of principal and rate: $49,236.45 * 1.05 = $51,698.27

Next, multiply this result by the time: $51,698.27 * 2 = $103,396.54
