Answer:
[tex]A(-1,-8)[/tex]
Step-by-step explanation:
Given
Point: A(2,6)
Translation: 1 left and 3 up
Rotation: 180 degrees
Required
Image of Point A
Taking the exercise one after the other
Represent the function as: (x,y)
Such that
[tex]A(x,y) = A(2,6)[/tex]
1 unit left translation means the function becomes (x - 1, y)
2 unit up translation means the function becomes (x - 1, y + 2)
Applying the above transformation
[tex]A(2,6) -> A(2-1,6+2)[/tex]
[tex]A(2,6) -> A(1,8)[/tex]
At this stage, the coordinate becomes
[tex]A(1,8)[/tex]
When a function (x,y) is rotated by 180, the new function becomes (-x,-y)
So;
The further transformation of A is
[tex]A(1,8) -> A(-1,-8)[/tex]
Hence, the new image of A is
[tex]A(-1,-8)[/tex]

Endpoints of segment MN have coordinates (0, 0), (5, 1). The endpoints of segment AB have coordinates (1 1/2 , 2 1/4 ) and (−2 1/4 , k). What value of k makes these segments parallel?
Answer:
k=21
Step-by-step explanation:
Find the slope of MN which is 1/5, (use the slope formula.)
Use the slope formula for AB using k as y_2
Substitute and you get k=21
21-2.25/-2.25-1.5=-5
The lines are perpendicular because the slopes are the negative reciprocal of one another.
For K = 5.3, the line segments are parallel.
We have endpoints of segment MN have coordinates (0, 0), (5, 1) and endpoints of segment AB have coordinates (1 1/2 , 2 1/4 ) and (−2 1/4 , k).
We have to determine the value of k that makes these segments parallel.
What is the condition for the lines to be parallel?For lines to be parallel - slope of line 1 should be equal to slope of line 2.
m(1) = m(2)
According to question, we have -
Coordinates of M = (0, 0)
Coordinates of N = (5, 1)
Therefore, the slope of line MN = [tex]\frac{1 -0}{5-0}[/tex] = 1/5
Coordinates of A = (11/2, 21/4)
Coordinates of B = (-21/4, k)
Therefore, the slope of line AB =
[tex]$\frac{k -\frac{21}{4} }{\frac{-21}{4} -\frac{11}{2} }[/tex] = [tex]$\frac{k - \frac{21}{4} }{\frac{1}{4} }[/tex] = [tex]$\frac{\frac{4k - 21}{4} }{\frac{1}{4} }[/tex] = 4k -21
Now, for the lines to be parallel -
m(MN) = M(AB)
4k - 21 = [tex]\frac{1}{5}[/tex]
5(4k - 21) = 1
20k - 105 = 1
20k = 106
k = 5.3
Hence, for K = 5.3, the line segments are parallel.

The scores of players on a golf team are shown on the table Celia-3 Janine 3 Sami 1 Ted 4 Travis 0 The team combined score was 0. What was Travis score?
His score would have to be -5:
-3 + 3 = 0
0 + 1 = 1
1 + 4 = 5
5 + (-5) = 0
So you know that the su of all the scores is 0.
The scores in the table are cecilia -3, janine 3, sami 1 and ted 4 and travis x, where x is the number that we want to know.
if we sum those, we have : 3 - 3 + 4 + 1 + x = 0
and we get 5 + x = 0
then x= -5, so travis's score is -5 points.
The base of o rectangle is triple the height
The height is 35 What is the base?
Write a algebraic expression and evaluate
Answer:
105 units
Step-by-step explanation:
Height of rectangle = 35 units
Since, base of o rectangle is triple the height.
Therefore, base of rectangle = 3*35 = 105 units
Another way:
h = 35 (given)
b = 3h
b = 3*35 (Plug h = 35)
b = 105 units
7. Which of the following is true?
1. For a pair of functions to be inverses, their compositions must be equal to 1.
2. In an inverse relation, coordinates of the ordered pairs are multiplied by 2.
3. An inverse of a function is always a function.
4. The horizontal line test is used to determine if a function's inverse will be a function.
Answer:
The horizontal line test is used to determine if a functions inverse will be a function. You will compose the functions (that is, plug x into one function, plug that function into the inverse function, and then simplify) and verify that you end up with just "x". Here's what it looks like: Determine algebraically whether f (x) = 3x – 2 and g(x) = (x + 2)/3 are inverses of each other.
Use the horizontal line test to determine if a function is a one-to-one function.
If ANY horizontal line intersects your original function in ONLY ONE location, your function will be a one-to-one function and its inverse will also be a function.
hope this helps
The horizontal line test is used to determine if a function's inverse will be a function is true. Correct option is 4.
1. This statement is not true. For a pair of functions to be inverses, their compositions (f(g(x)) and g(f(x))) must result in the identity function (1) for all values of x, not just for a specific value.
2. This statement is not true. In an inverse relation, the coordinates of the ordered pairs are swapped (x becomes y and y becomes x), not multiplied by 2.
3. This statement is not true. While many functions have inverses that are also functions, it is not a universal rule. Some functions may not have an inverse that is a function.
4. This statement is true. The horizontal line test is used to determine if a function has an inverse that is also a function. If a horizontal line intersects the graph of the function at more than one point, then the function does not have an inverse that is a function. However, if every horizontal line intersects the graph at most once, then the function does have an inverse that is a function.

Answer:
18 paperclips are in the pile!
Step-by-step explanation:
We know that a dozen paperclips are equal to 9.6g, so we are going to divide 9.6 by 12 to figure out how much each paperclip weighs (0.8g). So we then divide 14.4 by 0.8 to figure out how many paperclips are in the pile! Hope this helps!

Answer: [tex]\frac{\sqrt{3} }{2}[/tex]
Step-by-step explanation:
To find sin(60), you need to know the unit circle. Sin(60) is the same as sin(π/3). On the unit circle, sin(π/3) is √3/2. We know this because the coordinates are (cos, sin). Sin is the y coordinate.

In this triangle we have:
[tex]opposite=a\sqrt3\\hypotenuse=2a[/tex]
