Q and D are points on a polygon. Q' D' are points of the polygon under a translation. Determine the translation. Write your answer as (x,y).
Q (4,5) Q' (9,-1)
D (-5,-2) D' (0,-8)
Answers
Answer:
The translation is (5, -6)
Step-by-step explanation:
If the point (x, y) translated h unit right and k unit up, then its image is (x + h, y + k) and the translation is (h, k)If the point (x, y) translated h unit left and k unit up, then its image is (x - h, y + k) and the translation is (-h, k)If the point (x, y) translated h unit right and k unit down, then its image is (x + h, y - k) and the translation is (h, -k)If the point (x, y) translated h unit left and k unit down, then its image is (x - h, y - k) and the translation is (-h, -k)Let us solve the question
∵ The coordinates of point Q are (4, 5)
∴ x = 4 and y = 5
∵ The coordinates of point Q' are (9, -1)
∴ x' = 9 and y' = -1
→ That means x increased and y decreased ⇒ 3rd case above
∴ The point Q is moved to the right and down
→ By using the 3rd rule above ⇒ (x + h, y - k)
∵ x + h = 9
∵ x = 4
→ Substitute x by 4
∴ 4 + h = 9
→ Subtract 4 from both sides
∵ 4 - 4 + h = 9 - 4
∴ h = 5
∵ y - k = -1
∵ y = 5
→ Substitute y by 5
∴ 5 - k = -1
→ Subtract 5 from both sides
∵ 5 - 5 - k = -1 - 5
∴ -k = -6
→ Divide both sides by -1
∴ k = 6
∵ The translation is (h, -k) in the 3rd case
∵ h = 5 and k = 6
∴ The translation is (5, -6)
We can check the rule by finding D' the image of the point D
∵ D = (-5, -2)
∵ D' = (x + h, y - k)
∵ D' = (-5 + 5, -2 - 6)
∴ D' = (0, -8) as the given point D'
∴ The translation is correct
In a soccer game, Dalton scores 5 out of 8 shots on the goal. If he continues at that same rate, how many goals would he score if he made 168 shots on the goal?
Answers
Answer:
He would have made 105 shots!
Step-by-step explanation:
8 shots × 21 is 168
5 shots × 21 is 105

table to help
115
2. Write an equation that gives the amount of snow that has fallen after
x hours at this rate.
3. How many inches of snow will fall in 24 hours if it continues to snow at
this rate?
Answers
Answer:
13 inches ; 2 inches per hour ; 48 inches
Step-by-step explanation:
Given that :
Inches of snow after 2 hours = 4 inches
Since, snow is falling steadily ;
We can infer that:
Inches of snow per hour : (4 in / 2 hrs) = 2 in / hr
Hence, rate of snow fall = 2in /hr
Inches of snow after 6.5 hours
Rate per hour * Numbee of hours
2 * 6.5
= 13 inches
Amount of snow after x hours :
Rate * x
2 * x
= 2x
Inches of snow after 24 hours
2 * 24 hrs = 48 inches

We could follow the same set of steps as shown back in part (i), but I'll show a different approach. Feel free to use the method I used back in part (i) if the visual approach doesn't make sense.
The diagram below is a visual way to organize all the terms. Many textbooks refer to it as "the box method" which helps multiply out any two algebraic expressions.
Each inner cell is found by multiplying the corresponding outer terms. For instance, in the upper left corner we have 2x*2x = 4x^2. The other cells are filled out the same way.
The terms in those four inner cells (gray boxes) are:
4x^2-14x-2x7The like terms here are -14x and -2x which combine to -16x, since -14+(-2) = -16.
We end up with the answer 4x^2-16x+7

Describe how the graph of y= x^2 can be transformed to the graph of the given equation.
y = x^2 - 12 (5 points)
a) Shift the graph of y = x2 left 12 units.
b) Shift the graph of y = x2 down 12 units.
c) Shift the graph of y = x2 right 12 units.
d) Shift the graph of y = x2 up 12 units.
Answers
Answer:
b
Step-by-step explanation:
Given y = x² then y = x² + c is a vertical translation of y = x²
• If c > 0 then a shift up of c units
• If c < 0 then a shift down of c units
Here c = - 12 < 0
Thus y = x² - 12 is the graph of y = x² shifted 12 units down → b
Answer:
b) Shift the graph of y = x2 down 12 units.
Step-by-step explanation:
Graphs
The graph of the function
[tex]y=x^2[/tex]
can be found by giving the variable x some values and calculating the values of y as follows:
For x=-2, [tex]y=(-2)^2=4[/tex]. Point (-2,4)
For x=-1, [tex]y=(-1)^2=1[/tex]. Point (-1,1)
For x=0, [tex]y=(0)^2=0[/tex]. Point (0,0)
For x=1, [tex]y=(1)^2=1[/tex]. Point (1,1)
For x=2, [tex]y=(2)^2=4[/tex]. Point (2,4)
The graph of
[tex]y=x^2-12[/tex]
Can be similarly found:
For x=-2, [tex]y=(-2)^2-12=-8[/tex]. Point (-2,-8)
For x=-1, [tex]y=(-1)^2-12=-11[/tex]. Point (-1,-11)
For x=0, [tex]y=(0)^2-12=-12[/tex]. Point (0,-12)
For x=1, [tex]y=(1)^2-12=-11[/tex]. Point (1,-11)
For x=2, [tex]y=(2)^2-12=-8[/tex]. Point (2,-8)
The graphs are shown in the attached image. It can be clearly seen that the second graph (in blue) is shifted down 12 units with respect to the red graph. Answer:
b) Shift the graph of y = x2 down 12 units.
find the measures of the numbered angles in the rhombus, will give brainliest ! pls show how you solved it :)))
Answers
Answer:
∠1 = 72°
∠2 = 54°
∠3 = 54°
∠4 = 72°
Step-by-step explanation:
In the isosceles triangle in which ∠4 is the top vertex angle and ∠3 & 54° are it's base angles. As it is an isosceles triangle , ∠3 = 54°
Using angle sum property of a triangle ,
∠4 + ∠3 + 54° = 180°
⇒ ∠4 + 54°+ 54° = 180°
⇒ ∠4 = 180° - 108° = 72°
Diagonals of a rhombus bisect the vertex angles of a rhombus. So,
∠2 = ∠3 = 54°
Also , opposite vertex angles of a rhombus are equal, So , ∠1 = ∠4 = 72°

Scientist Dr. Sparks counted the flashes of lightning he saw around his home town for three months. He saw 25 in June, 51 in July, and 62 in August. A. What is the average number a month? B. What is the average number he saw in a day? If you help, please answer quickly after this is posted!!!
Answers
Answer:
Average number in a month = 46
Average number in a day = 1.5
Step-by-step explanation:
Given that:
Scientific Dr. Sparks has counted the flashes of lightning around his home for a period of 3 months.
Number of sparks counted in June = 25
Number of sparks counted in July = 51
Number of sparks counted in August = 62
To find:
Average number in a month ?
Average number in a day ?
Solution:
Average of observations can be defined as the ratio of total sum of all the observations to the total number of observations.
[tex]Average = \dfrac{\text{Sum of all observations}}{\text{Total number of observations}}[/tex]
Average as per month = [tex]\frac{25+51+62}{3} =\frac{138}{3} = 46[/tex]
To find the average number in a day, we need to first find the number of days.
Number of days in June = 30
Number of days in July = 31
Number of days in August = 31
Total number of days = 92
Average as per month = [tex]\frac{25+51+62}{92} =\frac{138}{92} = 1.5[/tex]

Enter the range of values for x: AB=AD
Answers
Answer:
6 < x < 30
Step-by-step explanation:
The angle of the side AB = 48 degrees
the angle of the side AD = 2x - 12 degrees
If the angle AD is greater than zero;
2x -12 > 0
= 2x > 12
= x > 12/ 2
= x > 6
if the maximum angle of AD is equal to angle AB, then;
= 2x -12 = 48
2x = 48 + 12
2x/ 2 = 60 / 2
x = 30
Therefore, the range of x is; 6 < x < 30
