One root of the equation "[tex]x^{2} -m^{2}x -m + 1 = 0[/tex]" (with unknown x) is the number "x1 = 1". Determine the other root "x2".
Answer:
0; 3.
Step-by-step explanation:
1) if to substitute x=1 into the given equation, it is possible to calculate the value of 'm':
1-m²-m+1=0; ⇔ m²+m-2=0; ⇒ m₁=-2; m₂=1;
2) if m=-2 and m=1, then the initial equation is:
x²-4x+3=0 or x²-x=0;
3) according to the item 3), the 2d root is:
x₂=3 or x₂=0.
What’s the inverse of the function?
f(x)=3^x+1
[tex]y= f(x) = 3^x+1\\\\\text{Replace x with y and solve for y}\\ \\~~~~~~x=3^y+1\\\\\implies 3^y = x-1\\ \\\implies \ln(3^y) = \ln(x-1)\\\\\implies y \ln 3= \ln(x-1)\\\\\implies y= \dfrac{\ln(x-1)}{\ln 3}\\\\\implies f^{-1}(x) = \dfrac{\ln(x-1)}{\ln 3}[/tex]

Solve the equation on the
interval [0,21).
2 csc x + 17 = 15 + CSC X
Answer:
7π/6, 11π/6
Step-by-step explanation:
2cscx + 17 = 15 + cscx
1. Subtract cscx and 17 from both sides ⇒ cscx = -2
2. cscx = 1/sinx ⇒ 1/sinx = -2
3. Multiply by sinx and divide by -2 ⇒ sinx = -1/2
When is sinx equal to -1/2? ⇒ 7π/6, 11π/6
The solution of the equation 2cosec x+17 = 15+cosec x is 7π/6 and 11π/6.
What is the solution of the given equation in the interval [0, 2π)?Given:
The equation which is given is 2Cosec x + 17 = 15 + Cosec x.The interval is [0,2π).Find:
The solution of the given equation.Solution:
2Cosec x + 17 = 15 + Cosec x
⇒ 2Cosec x - Cosec x = 15 - 17
⇒ Cosec x = -2
Now, 1/sinx = -2
⇒ sinx = -1/2
we know, sin 30° = 1/2
Since, sinx is negative,
x will be in 3rd and 4th quadrant.
value in 3rd quadrant = 180° + 30° = 210°
value in 4th quadrant = 360° - 30° = 330°
So, x = 210° = 210 * π/180 = 7π/6
Also, x = 330° = 330 * π/180 = 11π/6

Suppose that you are a member of the typical American household and your family carries a credit card debt of
$7942. Use the TVM (Time-Value-of-Money) Solver to model a few credit card scenarios. (Note: Use months
rounded to the nearest hundredths on all calculations.)
1. If the average annual interest rate is 17.11%, how many months will it take the average American family
to pay off their debt of $7,942 if they make a minimum payment of $175 each month and no additional
purchases are made?
2. How much interest did you pay during this time?
1. At an annual interest rate of 17.11%, an average family needs 74 months to settle $7,942 at a $175 monthly payment.
2. The total interest is $4,932.10.
What is a monthly payment?The monthly payment is the amount paid each month to settle the loan within its maturity period.
The monthly payment can be computed using an online finance calculator.
We can also determine the period of payment using the same online finance calculator as below.
Data and Calculations:I/Y (Interest per year) = 17.11%
PV (Present Value) = $7,942
PMT (Periodic Payment) = $-175
FV (Future Value) = $0
Results:
N = 73.566
Sum of all periodic payments = $12,874.10
Total Interest = $4,932.10
Thus, while it will take 74 months for the average American family to pay off the loan of $7,942 with a monthly payment of $175 at 17.11% interest, the total interest paid is $4,932.10.

The red square is the image of the blue square after a SINGLE transformation. Use two or more complete sentences to describe each of the FOUR different transformations that could produce the image.
The transformations which can lead to the red square image of the blue Square are; Translation, Reflection, Rotation.
What transformations lead to the image?Translation is when we slide a figure in any direction. The translation of the shape can be by moving the blue leftward or rightward and the then downward.Reflection is when we flip a figure over a line. The reflection involves reflect the blue Square over the line; y = x.Rotation is when we rotate a figure a certain degree around a point. The rotation is by rotating the blue Square over 180⁰.Read more on transformations;

What is the area of the shaded sector of Point B below?
Answer:
A) 175π / 9 squared inches,
Step-by-step explanation:
Radius = 10 inches
AB = BD = 10 = radius
Triangle ABD is isosceles
Angle DAB = Angle BDA = 35 degrees,
Base angles theroem
35 + 35 + x = 180, angles in triangle
x = 180 - 70
x = 110 degrees
Angle DBC is supplementary with ABD
110 + x = 180
x = 70
70 degrees is angle for the sector
70 is 70/360, 7/36 of the circle
The area will also be 7/36 of the circle area
Area of circle = πr^2
Area = 100π
Area of sector = (100π * 7) / 36
Area of sector = 700π / 36
Simplified area = 175π / 9 squared inches

If it takes 3.6 minutes to fill a 3000ml container, how long will it take to fill a 1.5L container?
Answer:
1.8 min
Step-by-step explanation:
This question is easier to answer than it would be in general.
3000 mL = 3 L
1.5L is exactly half of that, so the time to fill the 1.5L container is half the time it takes to fill the 3L container.
Half of 3.6 minutes is 1.8 minutes
The endpoints of AB are A(4,3) and B(1,1). What are the coordinates of A’’ after the image has been translated (x,y)—> (x-5,y-1) and rotated 180 degrees about the origin?
Answer:
A"(1, -2)
Step-by-step explanation:
In addition to the translation transformation given, you are asked to transform the figure further by rotating it 180° about the origin. The translation for that is ...
(x, y) ⇒ (-x, -y)
Then the composition of the two transformations is ...
(x, y) ⇒ (-(x -5), -(y -1)) = (-x +5, -y +1)
__
Applied to the given point(s), we have ...
(x, y) ⇒ (-x +5, -y +1)
A(4, 3) ⇒ (-4 +5, -3 +1) = A"(1, -2)
B(1, 1) ⇒ (-1 +5, -1 +1) = B"(4, 0)
The coordinates of A" after translation and rotation are (1, -2).

The reference angle for (5pi)/4 is pi/4 , which has a terminal point of (sqrt2/2), (sqrt2/2). What is the terminal point of 5pi/4?
Using the unit circle, it is found that the terminal point of the angle 5pi/4 is given by:
A. [tex]\left(-\frac{\sqrt{2}}{2}, -\frac{\sqrt{2}}{2}\right)[/tex]
What is the unit circle?For an angle [tex]\theta[/tex] the unit circle is a circle with radius 1 containing the following set of points: [tex](\cos{\theta}, \sin{\theta})[/tex].
The angle 5pi/4 is in the third quadrant, as it is greater than pi and less than 1.5pi, in which both the sine and the cosine are negative. Hence, considering the reference angle, we have that:
[tex](\cos{(\left(\frac{5\pi}{4}\right)}, \sin{(\left(\frac{5\pi}{4}\right)}) = (-\cos{(\left(\frac{\pi}{4}\right)}, -\sin{(\left(\frac{\pi}{4}\right)}) = \left(-\frac{\sqrt{2}}{2}, -\frac{\sqrt{2}}{2}\right)[/tex]

Step-by-step explanation:
vertex form:
[tex]y = {a(x - h)}^{2} + k[/tex]
the negative sign in front of x^2 is also -1, which is the "a". A controls if the parabola will opek up or down, and the width of the function. In this problem, the parabola opens down. the -3 corresponds to "k" in vertex form. K is the vertical shift or the y coordinate of the vertex. If k is positive it moves up, and if it is negative it moves down. Because of the -3, the vertex of the parabola will move down 3 units on the y-axis.
