dilation with a scale factor of 2 centered at (1 2)
Answer:
The answer is below
Step-by-step explanation:
The question is not complete, but I would show how to solve.
Transformation is the movement of a point from its initial location to a new location. Types of transformation is reflection, translation, rotation and dilation.
Dilation is the enlargement or reduction of the size of an object by a factor.
If a point A(x, y) is dilated by a factor k with a center of dilation at (a, b), then the new point is:
A'(x, y) = [k(x - a) + a, k(y - b) + b]
Let us assume that point A(2, 0) dilation with a scale factor of 2 centered at (1, 2). Hence the new point is:
A'(x, y) = [2(2 - 1) + 1, 2(0 - 2) + 2] = (3, -2)

What is included between two congruent sides in an isoceles triangle
In an isosceles triangle that has exactly two equal sides, the equal sides are called legs and the third side is called the base. The angle included by the legs is called the vertex angle and the angles that have the base as one of their sides are called the base angles.
When dividing 3x4 – x^2 – 2x + 6 by 2x2 - x - 5, the remainder will be ...?
Answer: -7.5 maybe
Step-by-step explanation:
Katie is purchasing plates and mugs for her house.
She would like to buy at least 8 items. Plates cost
$8 each and the mugs cost $7 each, and she plans
to spend no more than $112. Write a system to
model the situation and then solve.
Step-by-step explanation:
Plate: $8 each
Mug: $7 each
Spend Limit: $112
Items Wanted: 8
Considering she wants eight items, she can split that in half and buy four of each item, plate and mug.
8 * 4 = 32
$32 for 4 plates.
7 * 4 = 28
$28 for 4 mugs.
However, if she wanted to spend all the money, she could buy a few more of each item.
On a unit circle, the vertical distance from the x-axis to a point on the perimeter of the circle is twice the horizontal distance from the y-axis to the same point. What is sin of theta
Answer:
2/√5
Step-by-step explanation:
A unit circle is a circle of unit radius. This means that the radius of a unit circle is 1.
Let a represent the horizontal distance. Therefore the vertical distance = twice the horizontal distance = 2a
We can get the hypotenuse using Pythagoras theorem:
hypotenuse² = a² + (2a)²
hypotenuse² = a² + 4a²
hypotenuse² = 5a²
hypotenuse = √5a²
hypotenuse = a√5
sin(θ) = opposite / hypotenuse
sin(θ) = vertical distance / hypotenuse
sin(θ) = 2a / a√5
sin(θ) = 2/√5

Is this a square root graph?
Is this graph a reflection of its parent graph?
this graph shifted _
The equation to this graph would transform the parent function f(x) to _
Answer:
Thus, [tex]y=-\sqrt{x+3}[/tex] represents the transformed graph on the attached figure, which is a translated square root graph i.e. vertically reflected across the y-axis and also horizontally translated or shifted 3 units to the left.
Step-by-step explanation:
Consider the function
y = f(x)
The rule of horizontal translation
y = f(x-h)
When 'h' is positive, the function is shifted to the right.
When 'h' is negative, the function is shifted to the left.
The rule of implying vertical reflection across the x-axis
y = -f(x)
Applying the rule:
We know that the square root function is
[tex]y=\sqrt{x}[/tex]
We know that if the graph would be reflected across the x-axis, then
[tex]y=-\sqrt{x}[/tex]
We know that is horizontally translated or shifted 3 units to the left, it implies +
3 inside the radical implies. Then the transformed function becomes .
Please check the attached diagram. From the diagram,
The blue graph shows the parent function [tex]y=\sqrt{x}[/tex].The red graph shows the transformed function i.e. vertically reflected across the y-axis and also horizontally translated or shifted 3 units to the left.Thus, [tex]y=-\sqrt{x+3}[/tex] represents the transformed graph on the attached figure, which is a translated square root graph i.e. vertically reflected across the y-axis and also horizontally translated or shifted 3 units to the left.

*random answers will be reported*
Answer:
(0, 13)
Step-by-step explanation:
The midpoint is halfway between the line segment. First find the distance from the starting point to the midpoint.
2-1 = 1. So Since the midpoint is behind the start point, we are going backwards (moving to the left on the x axis).
So 1 space left from the midpoint is 1-1=0.
For y, the distance between the start and mid is 6 - -1 = 6+1 = 7 spaces. Then add 7 spaces to the midpoint value of 6, so 7+6 = 13. We moved upwards on the y axis.

80 middle-school students went on a field trip to watch a performance of Alice In Wonderland. When the teacher took a survey, 70% of the students responded that they enjoyed the play. About how many students enjoyed the play?
Answer:
56 students
Step-by-step explanation:
Because there are 80 students and only 70% enjoyed it, 70% is equal to 0.7 so you would multiply 80 by 0.7.

What are coordinates in a graph?The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.
The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.
We have,
The equation of a line y = (1/2)x - 1
We will find some coordinates from the equation.
When x = 1,
y = 1/2 - 1
y = -1/2
When x = 2,
y = 1/2 x 2 - 1
y = 1 - 1 = 0
When x = 3,
y = 1/2 x 3 - 1
y = 3/2 - 1
y = 1/2
When x = 4.
y = 4/2 - 1
y = 2 - 1
y = 1
The coordinates that we can plot on the graph are:
(1, -1/2), (2, 0), (3, 1/2), and (4, 1)
The graph is given below

A parachutist's rate during a free fall reaches kilometers per hour. What is this rate in meters per second? At this rate, how many meters will the parachutist fall during seconds of free fall? Do not round your answers.
Complete question :
A parachutist's speed during a free fall reaches 162 kilometers per hour. What is this speed in meters per second? At this speed, how many meters will the parachutist fall during 20 seconds of free fall? Do not round your answers.
Answer:
45 m/s ; 900 meters
Step-by-step explanation:
Given that :
Speed = 162 kilometers per hour ;
The speed in meters per second can be found by:
162 km/hr = (162 * 1000)m / (60 * 60) second
162 km/hr = 162000m / 3600 s
162 km/hr = 45 m/s
At this speed, how many meters will the parachutist fall during 20 seconds of free fall?
Speed of free fall = 45m /s
Distance in meters after 20 seconds :
(45 m/s * 20s) = 900 meters
The residents of a city voted on wether to raise property taxes. The ratio of yes votes to no votes was 8 to 5. If there was 6856 yes votes, what was the total number of votes
Answer:
The total number of votes cast in the election was 11,141.
Step-by-step explanation:
To determine the number of negative votes in the voting, taking into account that the ratio of votes between positive and negative is 8 to 5 and that there were 6,856 positive votes, it is necessary to perform the following calculation:
6.856 / 8 x 5 = X
857 x 5 = X
4.285 = X
Therefore, there were 4,285 negative votes in the election. So, since 4,285 + 6,856 equals 11,141, the total number of votes cast in the election was 11,141.
If point P is Four-sevenths of the distance from M to N, what ratio does the point P partition the directed line segment from M to N into?
Answer:
m into5
Step-by-step explanation:
Answer:
ANSWER 4:3
Step-by-step explanation:
Given : A point P is 4/7 of the distance from M to N.
∴ Let the distance between M to N be d.
Also, the point P partition the directed line segment from M to N .
Thus , MN = MP+PN
Now, the ration of MP to PN will be :-
∴ Point P partitioned the line segment MN into 4:3.
