Answer:
f^-1(x)=x²+5 is yr answer.
stay safe healthy and happy.Inverse function for f(x) = √(x - 5) is f⁻¹(x) = x² + 5
What is inverse function?A function accepts values, performs some operation on those values, and produces an output. The inverse function works in line with the result and returns to the original function.
An inverse function returns the original value that the function provided the output for.
Given function
f(x) = √(x - 5)
Let y = √(x - 5)
Replacing y with x
x = √(y - 5)
Squaring both sides
x² = (y - 5)
x² + 5 = y
or y = x² + 5
Replacing y with f⁻¹(x)
f⁻¹(x) = x² + 5
Hence, f⁻¹(x) = x² + 5 is the inverse function for f(x) = √(x - 5)

In a right triangle, the hypotenuse has endpoints P(–3, 2) and Q(1, –3). If R represents the third vertex in the triangle and R is located in the third quadrant, what is the length of PR?
Answers
PR = 5 units.
Step-by-step explanation:Given:
Right triangle
Hypotenuse = P(–3, 2), Q(1, –3)
R = located in the third quadrant.
To calculate the length of PR,
(i) First make a sketch of the points P and Q. The diagram is attached to this response.
(ii) As shown in the diagram, the point R is located in the third quadrant and its distance from P is from point -3 to 2 on the y-axis.
There are 5 points between -3 and 2. Therefore, the length PR = 5 units

__m²
Composite made up of a rectangular prism surmounted by a triangular prism. The rectangular prism has dimensions of 16 meters wide by 20 meters long by 12 meters high. The triangular prism has dimensions of 16 meters wide by 20 meters long with a triangular altitude of 8 meters high.
Answers
Answer:
1764 m²Step-by-step explanation:
Refer to attached picture.
All given dimensions are given on the picture (not to scale).
Since altitude of the triangle and slant height is given, we can find the base of the triangle using Pythagorean:
[tex]b/2 = \sqrt{11.3^2-8^2} = \sqrt{64} = 8m, \\b = 16 m[/tex]It has 9 faces and the total surface area is:
S = 16*20 + 2(20*12) + 2(20*11.3) + 2(16*12) + 2(1/2*8*16) = 1764 m²Isaac finished eight of the ten homework problems. Phil has finished of the homework. How many more problems did Isaac finish?

Step-by-step explanation:
If Issac has finished 8/10 problems in the homework, and Phil has completed all of it, it can be concluded that Phil completed 10/10. 10/10 would equal a whole, or in this case, the entire homework. If Issac completed 8 problems, and Phil completed 10, subtract both values to find that Issac completed -2 more problems than Phil.

A 10-foot ladder is placed against a building so that the ladder makes a 78°
angle with the ground. To the nearest tenth of a foot, at what height does the
ladder touch the building?
Answers
Answer:
Step-by-step explanation:
The height of the ladder using trigonometric ratio is 9.8 feet.
What is trigonometry?Trigonometry is mainly concerned with specific functions of angles and their application to calculations. Trigonometry deals with the study of the relationship between the sides of a triangle (right-angled triangle) and its angles.
For the given situation,
The slanting height of the ladder = 10 foot
The ladder makes an angle = 78°
Let height of the ladder be 'h'.
The below diagram shows the ladder position.
The height of the ladder can be found by using trigonometric ratio,
[tex]sin \theta=\frac{perpendicular}{hypotenuse}[/tex]
⇒ [tex]sin78=\frac{h}{10}[/tex]
⇒ [tex]0.9781=\frac{h}{10}[/tex]
⇒ [tex]h=9.781[/tex] ≈ [tex]9.8[/tex]
Hence we can conclude that the height of the ladder using trigonometric ratio is 9.8 feet.

Jayna used the distributive property to simplify the expression 4(a + 2) and got(4a + 2). Do you agree with Jayna?
Answers
Answer:
No
Step-by-step explanation:
I would not agree with Jayna because using the distributive property, you can get:
4(a + 2) = 4(a) + 4(2) = 4a + 8
Jayna did not get the right answer because she did not distribute the 4 to the 2 in a + 2 and she only multiplied a by 4.

3 is added to 5 times a certain number and the result is multiplied by 5 the final answer is not more than 2 less than the number
Answers
Answer:
The number is less than - 0.708
Step-by-step explanation:
Given - 3 is added to 5 times a certain number and the result is multiplied by 5 the final answer is not more than 2 less than the number
To find - What is the number ?
Proof -
Let a number be x
Given that,
3 is added to 5 times a certain number
So,
The expression becomes 3 + 5x
Now,
Given that, the result is multiplied by 5
So,
The expression becomes (3 + 5x)× 5
Now,
Given that,
The final answer is not more that 2 less than the number.
So,
The equation becomes
(3 + 5x)× 5 ≤ x - 2
⇒15 + 25x ≤ x - 2
⇒15 + 2 + 25x - x ≤ 0
⇒17 + 24x ≤ 0
⇒24x ≤ -17
⇒x ≤ - [tex]\frac{17}{24}[/tex]
⇒ x ≤ -0.708
∴ we get
The number is less than - 0.708

Alice is searching online for tickets to a knicks game. Two weeks ago, the cost was $30. Now the cost is $39. What is the percent increase
Answers
Given:
Two weeks ago, the cost of tickets = $30
Now, the cost of tickets = $39
To find:
The percent increase.
Solution:
We have,
Initial value = $30
New value = $39
Formula for percentage increase is:
[tex]\%\text{increase}=\dfrac{\text{New value - Initial value}}{\text{Initial value}}\times 100[/tex]
Using this formula, we get
[tex]\%\text{increase}=\dfrac{39-30}{30}\times 100[/tex]
[tex]\%\text{increase}=\dfrac{9}{3}\times 10[/tex]
[tex]\%\text{increase}=3\times 10[/tex]
[tex]\%\text{increase}=30[/tex]
Therefore, the percent increase in the cost of tickets is 30%.
Sally can paint a room in 9 hours while it takes Steve 5 hours to paint the same room. How long would it take them to paint the room if they worked together?
Answers
Answer: About 3 hours and 5 minutes to paint the room together.
Step-by-step explanation:
Sally can paint 1/5 of the room in an hour and Steve can paint 1/8 of the room in an hour.
Room/Hour
1/5 ± 1/8 =8/40
8/40+5/40=13/40
How long to paint the room?
13/40 x 1= 40/13
40÷13=3.0777
So the answer will be Sally and Steve can paint the room in about 3 hours and 5 minutes
