Given the function: f(x) = x2 – 2x How can you restrict the domain so that f(x) has an inverse? What is the equation of the inverse function? x ≥ 0; f Superscript negative 1 Baseline (x) = 1 + StartRoot x + 1 EndRoot x ≥ 1; f Superscript negative 1 Baseline (x) = 1 + StartRoot x + 1 EndRoot x ≥ 0; f Superscript negative 1 Baseline (x) = 1 minus StartRoot x + 1 EndRoot x ≥ 1; f Superscript negative 1 Baseline (x) = 1 minus StartRoot x + 1 EndRoot
Answer:
D x > 2; f Superscript negative 1 Baseline (x) = 2 + StartRoot x + 2 EndRoot

Answer:
(b) x ≥ 1; f⁻¹(x) = 1+√(x+1)
Step-by-step explanation:
We can find the inverse function by solving for y:
x = f(y)
x = y² -2y
x +1 = y² -2y +1
x +1 = (y -1)²
√(x +1) = y -1
1 +√(x +1) = y
So, the inverse function is ...
[tex]f^{-1}(x)=1+\sqrt{x+1}[/tex]
For this, the root will be non-negative, so the minimum value of this function is 1. That is, the minimum value of x for which the original function has this as an inverse is 1.
The domain restriction is x ≥ 1.
The inverse function is f⁻¹(x) = 1+√(x+1)

How do I solve this using long division?
Answer:
x + 5
Explanation:
x^2 + 3x − 10 /x−2
= x^2 + 3x − 10 /x − 2
= (x−2)(x+5) /x−2
= x + 5

Find the side of square , if it's perimeter is 18cm .also find its area
Answer:
a side of a square with a 18cm ´perimeter would be 4.5cm
area would be 20.25
Step-by-step explanation:
You can calculate the area of a square by using both the length of one side and its perimeter. Divide the perimeter length by 4 to get the measurement for each side of the square.
15 In rectangle PRST, ST and RT are extended as shown in the diagram below. The measure
of ZPTR is x° and the measure of ZRTS is (2x – 57).
P
R
X
U
(2x - 57)
V
Find the measure of ZUTV.
Find the measure of ZSTV.
Answer:
Z PTS = 90°
or, Z PTS = Z PTR + Z PTS
or, 90° = x° + ( 2x - 57 )°
or, 3x° = 90° + 57°
or, 3x° = 147°
or x° = 49°
ans: Z PTR = Z UTV = 49°
Z STU = 180°
or, Z UTV + Z STV = 180°
or, 49° + Z STV = 180 °
or, Z STV = 180° - 49°
= 131°
ans : Z STV = 131°
She writes the expression (0.2) (14). Which change in Mikel's expression will lead her to the correct answer? The 14 in the expression could be changed to 28. The 0.2 in the expression could be changed to 0.4. The 14 in the expression could be changed to 70. The 0.2 in the expression could be changed to 2.
Complete question :
Mikel creates the table below to help her determine 40% of 70. She writes the expression Which change in Mikel’s expression will lead her to the correct answer?
Corresponding chart for the problem is attached below.
Answer:
The 0.2 in the expression could be changed to 2.
Step-by-step explanation:
40% of 70
Directly working this out, we obtain :
0.4 * 70 = 28
From the table :
To obtain same from the columns, 0.2 is adjusted to 2.
Hence, 2 * 14 = 28
A plot of land is in the shape of a triangle. Two of the angles measure 48 degrees and 74 degrees. The length of the side between them is 90 m.
a) calculate the perimeter of the plot, to the nearest meter.
b) calculate the area of the plot, to the nearest square meter.
Answer:
Perimeter = 271 meters
Step-by-step explanation:
third angle measure would have to be 180 - 122 = 58 degrees
you can use the law of sines:
sin 58° = sin 74°
90 b
.85 = .96
90 b
cross-multiply: .85b = 86.4
b = 102
now do again to find third side:
sin 58° = sin 48°
90 c
.85 = .74
90 c
.85c = 67
c = 79
now you know all 3 sides so add them to get perimeter (79+102+90) = 271
Suppose y varies directly with x. Write an equation if y = 4 when x = 0.4.

Answer:
D) 6
Step-by-step explanation:
set Q has 16 values which are all even values from 4 to 36
set Z has 11 values that are multiples of 3 from 4 to 36 (6,9,12,15,etc.) however, we have to eliminate the odd ones, leaving the following six:
6, 12, 18, 24, 30, 36
Answer:
D. 6
Step-by-step explanation:
Key skills needed: Set Similarity
1) The easiest way to teach this is by writing out each set, but I will show it to you in 2 ways.
2) The first way is by writing everything out.
Set Q = 4,6,8,10,12,14,16,18,20,22,24,26,28,30,32,34,36
Set Z = 3,6,9,12,15,18,21,24,27,30,33,36
(I only wrote out Set Z to 36 since Set Q ends at 36. Anything greater than 36 won't even be there in Set Q, so no point in writing more.
The numbers that are common in both sets are --> 6,12,18,24,30,36Therefore D would be your answer.3) The next way is with using a simple pattern.
Set Q contains all even numbers from 4 to 36
Set Z contains all multiples of 3 (no limits)
Therefore, the numbers that are in both sets would be:
The even multiples of 3 that are bigger than 4 and less than 36.
4) Those even multiples of 3 would be ---> 6,12,18,24,30,36
That means there are 6 numbers in common. That means D is your answer.Both show that D is the answer, so I would say D as the answer very confidently.

Genie worst five hours on Tuesday three hours on Wednesday 4.5 hours on Thursday if H represents her hourly pay rate which expression below shows the amount she earned
Answer:
12.5H
Step-by-step explanation:
Number of hours worked per day:
Tuesday = 3 hours
Wednesday =5 hours
Thursday = 4.5 hours
H = hourly pay rate
Total amount earned = 3 hours × H + 5 hours × H + 4.5 hours × H
= 3H + 5H + 4.5H
= 12.5H
The expression which shows the total amount she earned = 12.5H

Answer:
(c) 16πx^6y^10
Step-by-step explanation:
The applicable rules of exponents are ...
(ab)^c = (a^c)(b^c)
(a^b)^c = a^(bc)
__
Putting the expression for r in the formula, you have ...
A = πr^2
A = π(4x^3y^5)^2 . . . . . substitute for r
A = π(4^2)(x^(3·2))(y^(5·2)) = 16πx^6y^10

b. cos 2theta =
c. tan 2theta =
cot theta = 11, theta lies in quadrant III
a. sin 2theta =
Answer:
Step-by-step explanation:
cot θ=11
tan θ=1/11
[tex]\sin ~2\theta=\frac{2 \tan ~\theta}{1+\tan^2 \theta} =\frac{2*\frac{1}{11} }{1+(\frac{1}{11} )^2}=\frac{22 }{122} \\\\cos~2 \theta=\frac{1-tan^2 \theta}{1+tan^2\theta} =\frac{1-(\frac{1}{11})^2 }{1+(\frac{1}{11} )^2} =\frac{120}{122} =\frac{60}{61} \\tan 2 \theta=\frac{2 tan\theta}{1-tan^2 \theta} =\frac{2*(\frac{1}{11 } )}{1-(\frac{1}{11} )^2} =\frac{2*11}{120} =\frac{11}{60}[/tex]

True or False: If there are multiple operations inside a parentheses, you do not need to complete these in the order of PEMDAS.
Answer:
False
Step-by-step explanation:
I would say false. The operations inside should always go by PEMDAS unless instructed otherwise
Answer:
FALSE
Step-by-step explanation:
Within a set of parentheses, the order of operations should be followed. This is because you will get the wrong answer if you don't.

Mina created a miniature rocket launcher, and the graph shows the height of one of her
rockets relative to the ground over time, where the rocket's height (y) is measured in meters
and time (x) is measured in seconds. *
(2 points)
The Vertex represents
the maximum height of the rocket
the minimum height of the rocket
the moment before the rocket is launched
Answer:
Work individually or in teams of two to construct and launch paper rockets using a teacher-built PVC-pipe launcher.
Following the flight of their rocket, calculate the altitude their rocket achieved.
Based on the flight performance of their rockets, analyze their rocket designs, modify or rebuild them, launch again, and calculate the altitude achieved to determine if their changes affected the performance of the rocket.
Conclude the activity by writing a post-flight mission report.
