Answer:
Option B.
Step-by-step explanation:
We know that, if the graph of a function is reflected across the line y=x, then we get the graph of inverse of that function.
It means, the graph of inverse function is the mirror image of graph of function across the line y=x.
If h(x) is a function and h⁻¹(x) is its inverse function, then the line y = x is the perpendicular bisector of each segment connecting a point on h(x) to the corresponding point on h⁻¹(x).
Therefore, the correct option is B.
Answer:
the answer is b

What is the image of the point (6,0)(6,0) after a rotation of 180^{\circ}180 ∘ counterclockwise about the origin?
Answer:
(-6,0)
Step-by-step explanation:
Whether we rotate a point 180° clockwise or counterclockwise, we'll always end up at the same point.
When we rotate a point by 180°, assuming the original point is [tex](x,y)[/tex], the new coordinate becomes [tex](-x,-y)[/tex].
So:
[tex](-6,-0)\\\\(-6,0)[/tex]

f(x)=[tex]\sqrt{x+4}[/tex] and g(x)=[tex]x^{2}[/tex]
find f(g(-6)
Answer:
[tex]f(g(-6))=2\sqrt{10}[/tex]
Step-by-step explanation:
first we need to find g(-6)
[tex]g(x)= x^2\\\\g(-6)=(-6)^2\\\\g(-6)=36[/tex]
so g(-6)=36
so we need to find f(36)
[tex]f(x)=\sqrt{x+4} \\\\f(36)=\sqrt{36+4} \\\\f(36)=\sqrt{40}\\\\f(36)=\sqrt{4}* \sqrt{10} \\\\f(36)=2\sqrt{10}[/tex]
so that's answer
[tex]f(g(-6))=2\sqrt{10}[/tex]

Find all real zeros of the function f(x)= 12 A. 5,7 B. 12 C. 1 D. none
Answer:
D. NoneStep-by-step explanation:
Given the function f(x) = 12, the function is only a constant with no degree. For a function to have roots, it must have at least degree of 1. Let us write the function f(x) = 12 in terms of x
f(x) = 12x⁰
From the function above it can be seen that the introduction of x⁰ can not in any way affect the function of x because x⁰ will return 1.
From the function, it can be seen that the highest power of the variable x is zero. This means that the function has no roots.
Hence, there are no real zeros of the function.

Susan plans to rent a bike in New Orleans to tour the city. The cost of the rental is $20 per day. The cost of a helmet is $7 for as long as Susan needs the bike. Barbara has $250 to rent a bike for 15 days. Does Barbara have enough money? Explain. First answer gets Brainiest and 48 points hurry please tho
Answer:
No, she does not.
Step-by-step explanation:
Using the words here, we can create the expression [tex]20d + 7[/tex] where d is the number of days.
We can now substitute 15 in as d, to see how much this will cost.
[tex]20\cdot15 + 7\\\\300+7\\\\307[/tex]
So the total cost will be $307.
Since $307 is more than $250, she does not have enough money.

Paj is filling a -cubic-inch flower pot with soil from small bags. Each bag of soil contains cubic inches of soil. Exactly how many bags of soil are needed for Paj to fill the flower pot?
Complete Question
Paj is filling a 9-cubic-inch flower pot with soil from small bags. Each bag of soil contains 2 2/3 cubic inches of soil. Exactly how many bags of soil are needed for Paj to fill the flower pot?
Answer:
[tex]Number\ of\ Bags = 3\frac{3}{8}[/tex]
Step-by-step explanation:
Given
[tex]Flower\ Pot = 9 in^3[/tex]
[tex]Small\ Bag = 2\frac{2}{3} in^3[/tex]
Required
How many bag of soil can fill the flower pot
To solve this,we simply divide the volume of flower pots by the small bags. This is done as follows;
[tex]Number\ of\ Bags = \frac{Flower\ Pot}{Small\ Bag}[/tex]
[tex]Number\ of\ Bags = \frac{9 in^3}{2\frac{2}{3} in^3}[/tex]
Convert fraction
[tex]Number\ of\ Bags= \frac{9 in^3}{\frac{8}{3} in^3}[/tex]
[tex]Number\ of\ Bags = 9 in^3/\frac{8}{3} in^3[/tex]
[tex]Number\ of\ Bags = 9 * \frac{3}{8}[/tex]
[tex]Number\ of\ Bags = \frac{9 * 3}{8}[/tex]
[tex]Number\ of\ Bags = \frac{27}{8}[/tex]
[tex]Number\ of\ Bags = 3\frac{3}{8}[/tex]
Hence, the number of bags needed is [tex]3\frac{3}{8}[/tex]

Answer: They are both right triangles so you can use the Pythagorean Theorem to get the length of the missing side
12^2 = 144. 5^2 = 25. 144 + 25 = 169. 13^2 = 169. Or you could say the sure root of 169 is 13.
Step-by-step explanation:
The triangles are congruent because the three sides of triangle A are equal to the three sides of triangle B.
In geometry they call that proof "sss" meaning 3 same sides. Or you could prove by "sas" 2 equal sides and an equal angle.

Answer:
A. England = 56000000
B. 1.046 * 10^7
C. 9.7 to 2sf
Step-by-step explanation:
A. England = 5.60*10000000
=56000000
B. Wale = 3.14*1000000 = 3140000
Scotland = 5.44*1000000 = 5440000
Northern Ireland = 1.88*1000000 =1880000
Total = 10460000
In standard form =1.046*10^7
C. Total population as at 2018 = 66460000
expected population by 2041 = 72900000
increase or change = (72900000 - 66460000) = 6440000
% change = (6440000/66460000)*100
= 0.0969003912 * 100
= 9.69003912
= 9.7 to 2sf

a body of mass 2kg travelling with a velocity of 10 m/s what is the momentum this body colloids with another body of equal mass travelling in the same direction with a velocity of 5m/s what is the total momentum of the 2 objects before and after coliision
Your question has been heard loud and clear.
M1 = 2kg , M2=2kg , V1=10m/s V2=5m/s
Total momentum before collision = M1V1+M2V2 = 2*10 + 2*5 = 30kgm/s
Now , by law of conservation of momentum ,
Total momentum before collision = total momentum after collision
Therefore , total momentum of objects before and after collision = 30kgm/s

Answer:
0.5 m³
Step-by-step explanation:
You have a rectangular prism and a cube. Find the volume of each separately. After solving, add the two volumes together to find the total volume.
Cube
The side length is 0.5 m.
V = a³
V = (0.5 m)³
V = 0.125 m³
Rectangular Prism
The height is 0.75 m, the width is 0.5 m, the length is 1 m.
V = lwh
V = (0.75 m)(0.5 m)(1 m)
V = 0.375 m³
0.125 m³ + 0.375 m³ = 0.5 m³

Hadley buys 7 boxes of markers with 8
in each box. Delaney buys 6 boxes of
markers with 12 markers in each box.
How many markers did Hadley and
Delaney buy in all?
Answer:
128 markers.
Step-by-step explanation:
7 x 8 = 56
12 x 6 = 72
72+ 15 = 87
Hadley and Delaney therefore bought 128 markers all in total.
Hope I helped ! :))))))
The amount of markers Hadley and Delaney bought in all is equal to 128 markers.
Given the following data:
Hadley = 7 boxes of markers with 8 in each box.Delaney = 6 boxes of markers with 12 markers in each box.To determine the amount of markers Hadley and Delaney bought in all:
First of all, we would determine the total number of marker in each box.
For Hadley:
[tex]Hadley = 7 \times 8[/tex]
Hadley = 56 markers
For Delaney:
[tex]Delaney = 6\times 12[/tex]
Delaney = 72 markers
Now, we can find the total markers:
