Answer:
Find the coordinates of the midpoint of the segment whose endpoints are H(2, 1) and K(10, 7).
Step-by-step explanation:
Answer:
{-1, 1, 3}
Step-by-step explanation:
Given the function
y = (x + 1)/3
The domain are the input value x while the range are the output values given the input value x;
Given the domain {-4, 2, 8}
when x = -4;
y = (-4+1)/3
y = -3/3
y = -1
when x = 2;
y = (2+1)/3
y = 3/3
y = 1
when x = 8;
y = (8+1)/3
y = 9/3
y = 3
Hence the member of the range are {-1, 1, 3}
Answer:
Step-by-step explanation:
To find the measure of angle DBC, we can use the angle bisector theorem, which states that in a triangle, if a line bisects one of the angles, it divides the opposite side into segments proportional to the other two sides. In this case, BD bisects angle ABC, so:m∠ABD / m∠DBC = AB / BCWe are given:
m∠ABC = 8x
m∠ABD = 2x + 30So, we have:(2x + 30) / m∠DBC = AB / BCNow, we need to express AB / BC in terms of x. To do that, we'll use the fact that angles in a triangle add up to 180 degrees:m∠ABC + m∠ABD + m∠DBC = 180Substitute the given angle measures:8x + (2x + 30) + m∠DBC = 180Combine like terms:10x + 30 + m∠DBC = 180Now, isolate m∠DBC:m∠DBC = 180 - 10x - 30
m∠DBC = 150 - 10xNow, we can substitute this expression for m∠DBC back into our proportion:(2x + 30) / (150 - 10x) = AB / BCNow, you can solve for m∠DBC:Cross-multiply:(2x + 30)(BC) = (150 - 10x)(AB)Now, you would need more information about the relationship between AB and BC or additional angle measures to solve for the exact value of m∠DBC. Without that additional information, you can't determine the specific angle measure.
The correct option is (A). and are connected at point Y. is reflected across XY and then is reflected another time across YZ to form .
Given, and are connected at point Y.
is reflected about XY will shift the marked angle from left to right while the right side angle will remain at the same location and the triangle will remain upright to give
Reflection about the YZ will give the marked angle and the right angle in the same location and the vertex X will then be changed to P.
Thus , can be mapped to with two reflections.
In the second option, we have is reflected 3 times which is more than 2 times as said in question. so this statement is false.
In next option is reflected across side XY and then is shifted downwards to form .since here we have only one reflection, so this statement is also false.
4) In option 4 is reflected and then rotated thus option 4 is also not a correct option.
Hence the correct statement is and are connected at point Y. is reflected across XY and then is reflected another time across YZ to form .

Answer:
The correct option is the first option;
Triangle XYZ and PYT are connected at point Y. Triangle XYZ is reflected across XY and then is reflected another time across YZ to form triangle PYT
Step-by-step explanation:
To answer the question we look at each option as follows;
1) The parameters given are triangle XYZ and PYT are connected at point Y
Triangle XY is reflected about XY will shift the marked angle from left to right while the right angle will remain at the same location and the triangle will remain upright to give triangle X'Y'Z'
Reflection about the YZ will give; the marked angle and the right angle in the same location and the vertex X will then be changed to P
Therefore, triangle XYZ can be mapped to triangle PYT with two reflections
2) In the second option, we have triangle XYZ is reflected 3 times which is more than 2 times as in the question, therefore, option two is less suited as an answer to the question
3) Triangle XYZ is reflected across side XY and then is shifted down to form triangle AYT
Therefore, since we have only one reflection, option 3 is also not appropriate as an answer
4) In option 4 triangle XYZ is reflected and then rotated therefore option 4 is also not a correct option.
Radius is half the diameter.
The diameter is shown as 16, so the radius would be 16/2 = 8 in.
Area = 3 x 8^2
Area = 3 x 64
Area = 192 square inches
Answer:
A = 192
Step-by-step explanation:
r = 16/2 = 8
A = 3x(8)^2
8^2 = 64
A = 3 x 64 = 192
