A) translated 9 units up and then reflected across the y-axis
B) translated 6 units to the right then translated 9 units up
C) translated 9 units to the right then translated 6 units up
D) translated 6 units to the right and then reflected across the x-axis
Answers
Answer:
B) translated 6 units to the right then translated 9 units up
Step-by-step explanation:
Just use the graph to follow each translation until you get thee right answer, or you can count how many spaces are from the pre-image to the image. Just make sure to always use the same point.
The transformation from figure A to figure A' are:
Translating 6 units to the right.
Translated 9 units up.
Option B is the correct answer.
What is translation?It is the movement of the shape in the left, right, up, and down directions.
The translated shape will have the same shape and shape.
There is a positive value when translated to the right and up.
There is a negative value when translated to the left and down.
We have,
We will take two coordinates from the figure.
Figure A has the coordinates:
(-5, -2) and (-4, -2)
And,
Figure A' has the coordinates:
(1, 7) and (2, 7)
Now,
Translating 6 units to the right.
(-5, -2) = (-5 + 6, -2) = (1, -2)
And,
(-4, -2) = (-4 + 6, -2) = (2, -2) _____(1)
Again,
Translated 9 units up.
(1, -2) = (1, -2 + 9) = (1, 7)
And,
(2, -2) = (2, -2 + 9) = (2, 7) ______(2)
From (1) and (2) we see that,
Figure A to Figure A'.
Translating 6 units to the right.
Translated 9 units up.
Thus,
The transformation from figure A to figure A' are:
Translating 6 units to the right.
Translated 9 units up.

How do I find the median for 77,82,87,85,32,78?
Answers
Answer:
80
Step-by-step explanation:
The median is the middle value of the data arranged in ascending order. If there is no exact middle then the median is the average of the 2 values either side of the middle
Arrange the data in ascending order ( smallest to largest )
32, 77, 78, 82, 85, 87
There is no value exactly in the middle, use the average
median = [tex]\frac{78+82}{2}[/tex] = [tex]\frac{160}{2}[/tex] = 80

what’s the area
A. 64
B. 44
C. 30.25
D. 13.75
Answers
Answer:
B) 44
Step-by-step explanation:
Let's start with the triangles. Normally, when dealing with triangles, you would use the formula (B*H*1/2), but since there's two identical triangles, we can just do (B*H) and get the area for both:
2.5*5.5=13.75
Then to solve for the square, it is also (B*H):
5.5*5.5=30.25
At this point, to solve for the total area, you just add the areas together:
13.75+30.25=44

Given h(f)=-2(t+5)^2 +4, find h(-8)
Answers
Answer:
h(-8) = 22
Step-by-step explanation:
Plug -8 in for t and simplify...
h(-8) = 2(-8 + 5)² + 4
h(-8) = 2(-3)² + 4
h(-8) = 2(9) + 4
h(-8) = 18 + 4
h(-8) = 22
Answer:
Step-by-step explanation:
Given h(f)=-2(t+5)^2 +4
There is an intermediate step which is
h(f) = -2(f + 5)^2 + 4
h(-8) = -2(-8 + 5)^2 + 4
h(-8) = -2(-3)^2 + 4
h(-8) = -2(9) + 4
h(-8) = -18 + 4
h(-8) = - 14
Which of these functions has an inverse function? Select all that apply.
y = x
y = x^2
y = x^3
y = x^4
Answers
ANSWER
y=x
y=x³
EXPLANATION
A function, f(x) has an inverse if and only if
[tex]f(a) = f(b) \Rightarrow \: a = b[/tex]
Thus, the function is one to one.
For y=x or
[tex]f(x) = x[/tex]
[tex]f(a) = f(b) \Rightarrow \: a = b[/tex]
Hence this function has an inverse.
For the function y=x² or f(x)=x².
[tex]f(a) = f(b) \Rightarrow \: {a}^{2} = {b}^{2} \Rightarrow \: a = \pm \: b[/tex]
This function has no inverse on the entire real numbers.
For the function y=x³ or f(x)=x³
[tex]f(a) = f(b) \Rightarrow \: {a}^{3} = {b}^{3} \Rightarrow \: a = b[/tex]
This function also has an inverse.
For y=x⁴ or f(x) =x⁴
[tex]f(a) = f(b) \Rightarrow \: {a}^{4} = {b}^{4} \Rightarrow \: a = \pm \: b[/tex]
This function has no inverse over the entire real numbers.
Answer:
The function [tex]x=y[/tex] and [tex]y=x^{3}[/tex] are inverse function.
Step-by-step explanation:
Function inverse definition:
If a provided function f(x) is mapped x to y, then the inverse of the provided function f(x) is mapped y to x.
Or [tex]f(x)=f(y)\Rightarrow x=y[/tex]
Now, consider the function y = x.
Interchange the variables x and y.
[tex]x=y[/tex]
Now, solve [tex]x=y[/tex] for [tex]y[/tex].
[tex]x=y[/tex]
Therefore, this function has an inverse.
Consider the function [tex]y=x^{2}[/tex].
Interchange the variables x and y.
[tex]x=y^{2}[/tex]
Now, solve [tex]x=y^{2}[/tex] for [tex]y[/tex].
[tex]\pm \sqrt{x} =y[/tex]
Therefore, the function has no inverse.
Consider the function [tex]y=x^{3}[/tex].
Interchange the variables x and y.
[tex]x=y^{3}[/tex]
Now, solve [tex]x=y^{3}[/tex] for [tex]y[/tex].
[tex]\sqrt[3]{x}=y[/tex]
Therefore, the function has inverse.
Consider the function [tex]y=x^{4}[/tex].
Interchange the variables x and y.
[tex]x=y^{4}[/tex]
Now, solve [tex]x=y^{4}[/tex] for [tex]y[/tex].
[tex]\pm \sqrt[4]{x}=y[/tex]
Therefore, the function has no inverse.
Hence, the function [tex]x=y[/tex] and [tex]y=x^{3}[/tex] are inverse function.

Kaleb used the distributive property to write two equivalent expressions. Use w = 5 and w = 10 to determine if the two expressions are equivalent. 12(w – 3) 12w – 36 When w = 5, both expressions have a value of 24. When w = 10, both expressions have a value of . Therefore, the expressions are equivalent.
Answers
When w is 5 both expressions have the same value 24.
When w is 10 both expressions have the same value 84.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
Substitute w = 5
12 (w - 3)
= 12 (5 - 3)
= 12 x 2
= 24
And,
12w - 36
= 12 x 5 - 36
= 60 - 36
= 24
Now,
Substitute w = 10
12 (w - 3)
= 12 (10 - 3)
= 12 x 7
= 84
And,
12w - 36
= 12 x 10 - 36
= 120 - 36
= 84
Thus,
When w is 5 both expressions have the same value.
When w is 10 both expressions have the same value.

When [tex]\( w = 10 \),[/tex]both expressions have a value of 84, and the expressions are indeed equivalent.
To determine if the two expressions [tex]\(12(w - 3)\) and \(12w - 36\)[/tex] are equivalent, we can evaluate both expressions for the given values of [tex]\(w\).[/tex]
When [tex]\(w = 5\),[/tex]we substitute [tex]\(5\)[/tex]into both expressions:
For the expression [tex]\(12(w - 3)\):[/tex]
[tex]\[12(5 - 3) = 12(2) = 24\][/tex]
For the expression [tex]\(12w - 36\):[/tex]
[tex]\[12(5) - 36 = 60 - 36 = 24\][/tex]
Both expressions evaluate to [tex]\(24\) when \(w = 5\).[/tex]
Now, let's evaluate both expressions when [tex]\(w = 10\):[/tex]
For the expression [tex]\(12(w - 3)\):[/tex]
[tex]\[12(10 - 3) = 12(7) = 84\][/tex]
For the expression [tex]\(12w - 36\):[/tex]
[tex]\[12(10) - 36 = 120 - 36 = 84\][/tex]
Since the values of both expressions are the same for [tex]\( w = 5 \) and \( w = 10 \),[/tex]we can conclude that the expressions are equivalent.

if you horizontally stretch the quadratic parent function, f(x)=x^2, by a factor of 3, what is the equation of the new function?
Answers
Answer: [tex]g(x)=\frac{1}{9}x^2[/tex]
Step-by-step explanation:
By definition, he quadratic parent function [tex]f(x)=x^2[/tex] is the simplest form of a quadratic function.
By definition, if the fucntion is multiplied by the factor b and:
|b|>0 the function is stretched.
If 0<|b|<1 the function is compressed.
Then the new function will have the form:
[tex]g(x)=(\frac{1}{b}x)^2[/tex]
Therefore, keeping the above on mind, if b=3, then the new function is:
[tex]g(x)=(\frac{1}{3}x)^2[/tex]

(h, k) - center
r - radius
The general form of an equation of a circle:
[tex]x^2+y^2+Dx+Ey+F=0[/tex]

Put thr coordinates of the point (-4, 1) to the equation and calculate a radius:

AC
tangent to circle k(O) at B and C respectively. Find BC, if m∠OAB=30°, and AB=5 cm.
Answers
Answer:
5 cm
Step-by-step explanation:
If AB is tangent to the circle k(O), then radius OB is perpendicular to segment AB.
If BC is tangent to the circle k(O), then radius OC is perpendicular to segment AC.
Consider two right triangles ABO and ACO. In these triangles:
AO is common hypotenuse;∠OBA=∠OCA=90°, because AB⊥OB, AC⊥OC;OB=OC as radii of the circle k(O).By HL theorem, triangles ABO and ACO are congruent. Then
∠OAB=∠OAC=30°;AC=AB=5 cm.Hence, ∠BAC=∠OAB+∠OAC=30°+30°=60°.
Consider triangle ABC, this triangle is isosceles triangle. In isosceles triangles angles adjacent to the base are congruent, thus
∠CBA=∠BCA=1/2(180°-60°)=60°.
Therefore, triangle ABC is an equilateral triangle, so BC=AB=AC=5 cm.
