NO LINKS!! Describe the set of all points P(x, y) in a coordinate plane that satisfy the given condition. Part 2
Answers
Part (d)
If xy > 0, then the two items x and y must have the same sign.
Examples where x,y are both positive
x = 2 and y = 5 leads to xy = 2*5 = 10x = 7 and y = 4 leads to xy = 7*4 = 28Examples where x,y are both negative
x = -1 and y = -9 leads to xy = -1*(-9) = 9x = -12 and y = -3 leads to xy = -12*(-3) = 36This places us in either the first quadrant or third quadrant (Q1 and Q3)
Q1 is where x > 0 and y > 0 (northeast corner)Q3 is where x < 0 and y < 0 (southwest corner)Answer: The set of all points in quadrants I and III (x and y have the same sign)======================================================
Part (e)
If y < 0, then we have points like (2,-5) and (1,-7). The x coordinate doesn't matter as long as the y coordinate is negative.
Visually speaking we are below the x axis. This places the point in Q3, Q4, or on the negative y axis. The point cannot be on the x axis. You can think of this point as being underground or underwater.
Answer: The set of all points below the x axis======================================================
Part (f)
If x = 0, then the point is on the vertical y axis. Recall that y intercepts always occur when x = 0. Two examples would be (0,4) and (0,12).
Answer: The set of all points on the y axis.Answer:
(d) The set of all points in quadrants I and III (x and y have the same sign).
(e) The set of all points below the x-axis.
(f) The set of all points on the y-axis.
Step-by-step explanation:
The Cartesian plane is divided into four quadrants.
Quadrant I is the upper right quadrant and the rest follow in a counterclockwise direction.
Quadrant I: x > 0 and y > 0 → (x, y)Quadrant II: x < 0 and y > 0 → (-x, y)Quadrant III: x < 0 and y < 0 → (-x, -y)Quadrant IV: x > 0 and y < 0 → (x, -y)Part (d)
For xy > 0, x and y should either both be positive or both be negative, i.e. have the same sign.
x and y are both positive in quadrant I.x and y are both negative in quadrant III.Therefore, the description that satisfies the given condition is:
The set of all points in quadrants I and III (x and y have the same sign).Part (e)
For y < 0, y is always negative.
y is negative in quadrant III.y is negative in quadrant IV.Quadrants III and IV are below the x-axis.
Therefore, the description that satisfies the given condition is:
The set of all points below the x-axis.Part (f)
The only place where x = 0 is the y-axis.
Therefore, the description that satisfies the given condition is:
The set of all points on the y-axis.

Step-by-step explanation:
you should have measured the lengths of the sides and added that information here to the picture.
because we here cannot measure this from a picture that is inclined and has no size scale.
I can give you a hint how to get the angles, when you have all 3 sides :
start with the extended Pythagoras for non right-angled triangles:
c² = a² + b² - 2ab×cos(C)
with c being the side opposite of the angle you are aiming for.
then
2ab×cos(C) = a² + b² - c²
cos(C) = (a² + b² - c²)/(2ab)
for example, to get the angle at T, its opposite side is SE.
cos(T) = (ST² + ET² - SE²)/(2×ST×ET)
you can do the same thing for all 3 angles (you need to always pay attention to what sides you have to use in what combination for the angle).
or you can switch after getting the first angle to the laser of sine :
a/sin(A) = b/sin(B) = c/sin(C)
where the sides and the disposing angles are always opposite of each other.
for your triangle that looks like
ET/sin(S) = ST/sin(E) = SE/sin(T)
from there (once you have one angle via the Pythagoras approach) you get all other angles.

2 \(\frac{2}{9}\) days
Step-by-step explanation:
Let d = the number of days.
\(\frac{1}{4}\) d = \(\frac{1}{5}\)d = 1
\(\frac{5}{20}\) d + \(\frac{4}{20}\) d = 1
\(\frac{9}{20}\) d = 1 Multiply both sides by \(\frac{20}{9}\)
(\(\frac{20}{9}\))(\(\frac{9}{20}\)) d = 1(\(\frac{20}{9}\))
d = \(\frac{20}{9}\) I can break 20 into 9 + 9 + 2
d = \(\frac{9}{9}\) + \(\frac{9}{9}\) + \(\frac{2}{9}\) \(\frac{9}{9}\) = 1
d = 1 + 1 + \(\frac{2}{9}\)
d = 2 \(\frac{2}{9}\)

Three of the exterior angles of an n-sided
polygon are 50° each,
two of its interior
angles are 127° and 135°,
and the remaining
interior angles are 173° each. Find the value of n.
Answers
Answer:
\(n=126\)
Step-by-step explanation:
Using the formula for the sum of the angles of an \(n\)-sided polygon, the sum of the angles is \(180(n-2)\) degrees.
An exterior angle is supplementary to the corresponding interior angle. Using the given angle measures, the sum of the angles is \(2(180-50)+127+135+173n=522+173n\) degrees.
Equating these two results,
\(180(n-2)=522+173n \\ \\ 180n-360=522+173n \\ \\ 7n-360=362 \\ \\ 7n=882 \\ \\ n=126\)
Answer:
n=126
Step-by-step explanation:
180(n−2)=522+173n
180n−360=522+173n
7n−360=362
7n=882

What are the coordinates of the point on the directed line segment from ( − 7 , 9 ) (−7,9) to ( 3 , − 1 ) (3,−1) that partitions the segment into a ratio of 2 to 3?
Answers
The coordinates of the point on the directed line segment from (-7, 9) to (3, -1) that partitions the segment into a ratio of 2 to 3 are (-3, 5).
To find the coordinates of the point that divides the directed line segment from (-7, 9) to (3, -1) into a ratio of 2 to 3, we can use the section formula.
Let's label the coordinates of the desired point as (x, y). According to the section formula, the x-coordinate of the point is given by:
x = (2 * 3 + 3 * (-7)) / (2 + 3) = (6 - 21) / 5 = -15 / 5 = -3
Similarly, the y-coordinate of the point is given by:
y = (2 * (-1) + 3 * 9) / (2 + 3) = (-2 + 27) / 5 = 25 / 5 = 5
Therefore, the coordinates of the point that divides the line segment in a ratio of 2 to 3 are (-3, 5).
To understand this conceptually, consider the line segment as a distance from the starting point (-7, 9) to the ending point (3, -1). The ratio of 2 to 3 means that the desired point is two-thirds of the way from the starting point and one-third of the way from the ending point. By calculating the x and y coordinates using the section formula, we find that the desired point is located at (-3, 5).

Use the image to determine the direction and angle of rotation. Graph of triangle ABC in quadrant 1 with point A at 1 comma 3. A second polygon A prime B prime C prime in quadrant 4 with point A prime at 3 comma negative 1. 90° clockwise rotation 180° clockwise rotation 180° counterclockwise rotation 90° counterclockwise rotation
Answers
First, we can find the translation vector that moves point A to point A':
translation vector = A' - A = (3, -1) - (1, 3) = (2, -4)
Next, we can find the vector that connects point B to point A in the original triangle ABC:
vector AB = B - A
Then, we can rotate this vector using the rotation matrix for the desired angle of rotation:
90° clockwise rotation:
|0 -1| |x| |y'|
|1 0| * |y| = | -x'|
180° clockwise rotation:
|-1 0| |x| |x'|
| 0 -1| * |y| = |y'|
180° counterclockwise rotation:
|-1 0| |x| |-x'|
| 0 -1| * |y| = |-y'|
90° counterclockwise rotation:
| 0 1| |x| |-y'|
|-1 0| * |y| = | x'|
Finally, we can add the translation vector to the rotated vector to get the coordinates of the corresponding point in the new polygon A' B' C':
90° clockwise rotation: B' = A' + (AB rotated 90° clockwise + translation)
180° clockwise rotation: B' = A' + (AB rotated 180° clockwise + translation)
180° counterclockwise rotation: B' = A' + (AB rotated 180° counterclockwise + translation)
90° counterclockwise rotation: B' = A' + (AB rotated 90° counterclockwise + translation)
Using this method, we can find the coordinates of points B' and C' in the new polygon A' B' C'. Then, we can use the coordinates of these points to determine the direction and angle of rotation needed to move the original triangle to the new polygon.

A dog shelter is giving away 19 different dogs, but you have room for only 4 of them. How many different dog families could you create?
Answers
The 19 tykes given away by the Shelter, that have room for only 4 tykes per family.
The number of different canine families that could be created from the 19 tykes given away by the sanctum, we need to calculate the number of combinations. room for only 4 tykes , we need to choose 4 tykes from the aggregate of 19 tykes . The order of the tykes in the family doesn't count, as long as we choose different tykes for each family. The number of combinations can be calculated using the formula for combinations C( n, r) = n!/( r!( n- r)!) Where C( n, r) represents the number of combinations of choosing r particulars from a set of n particulars. In this case, we've n = 19( total number of tykes ) and r = 4( number of tykes per family). Plugging these values into the formula, we get C( 19, 4) = 19!/( 4!( 19- 4)!) Calculating the factorial values 19! = 19 × 18 × 17 × 16 × 15 × 14 × 13 × 12 × 11 × 10 × 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1 = ! = 4 × 3 × 2 × 1 = 24 15! = 15 × 14 × 13 × 12 × 11 × 10 × 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1 = Substituting these values into the formula C( 19, 4) = /( 24 ×) ≈ 91,390 The 19 tykes given away by the sanctum, considering that you have room for only 4 tykes per family.

OA. Yes, because 23 and 27 are congruent.
OB. No, because 27 and 25 are not congruent.
C. Yes, because 25 and 27 are supplementary.
D. No, because 23 and 25 are not supplementary.
Answers
The correct answer is D. No because 23 and 25 are not supplementary.
In the given diagram, it is stated that the measures of angles 23 and 27 are 45°, and the measure of angle 25 is 135°. To determine if lines C and D are parallel, we need to analyze the angles formed by these lines.
If the alternate interior angles or corresponding angles are congruent, then the lines are parallel. However, in this case, we don't have enough information about the angles formed by lines C and D to make that determination.
The fact that angle 23 and angle 27 are congruent (both measuring 45°) doesn't provide any information about the relationship between lines C and D. Similarly, the measure of angle 25 being 135° doesn't give us any insight into the parallelism of lines C and D. Therefore, we cannot conclude that lines C and D are parallel based on the given information, and the correct answer is D.
