Answer: 128 months
Step-by-step explanation:
Final answer:
Jessie will break even on the point purchase for her mortgage in approximately 128 months, as a point costs 1% of the $135,000 home, and the monthly mortgage payment falls by $10.55 after purchasing the point.
Explanation:
The student is asking how many months it will take Jessie to break even on the purchase of a point for her mortgage. A point typically costs 1% of the loan amount, and in return, the lender reduces the interest rate on the mortgage. In this case, the monthly payment is reduced from $766.51 to $755.96, a monthly savings of $10.55 ($766.51 - $755.96).
To calculate the break-even point in months, divide the cost of the point by the monthly savings. If a point costs 1% of the $135,000 home, then the cost is $1,350 ($135,000 * 0.01). The number of months to break even is therefore $1,350 / $10.55, which equals approximately 128 months.
Therefore, the correct answer would be:

Which of the equations below could be the equation of this parabola?
Vertex (0, 0)
ОА. х = 3у2
Ов. х = -3y?
Ос. у= 3x2
O D. y=-3
Option C, [tex]y = 3x^2[/tex], is the equation that could represent the parabola with a vertex at (0, 0).
To determine which of the given equations could represent the parabola with a vertex at (0, 0), we need to consider the standard form of a parabolic equation: [tex]y = ax^2[/tex]
In this standard form, 'a' is a constant that determines the shape and orientation of the parabola. For a parabola with a vertex at (0, 0), the equation will be of the form [tex]y = ax^2[/tex].
Let's examine each option:
A. [tex]x = 3y^2[/tex]: This equation is not in the standard form [tex]y = ax^2.[/tex] It is a different type of equation and does not represent a parabola with a vertex at (0, 0).
B. x = -3y: Similarly, this equation is not in the standard form [tex]y = ax^2[/tex]. It represents a linear relationship between x and y, not a parabola.
C. [tex]y = 3x^2[/tex]: This equation is in the standard form [tex]y = ax^2[/tex], where a = 3. It represents a parabola with a vertex at (0, 0), so it could be the equation of the parabola in question.
D. y = -3: This equation is not in the standard form [tex]y = ax^2[/tex]. It represents a horizontal line with a constant value of -3, not a parabola.
Based on the analysis, Option C, [tex]y = 3x^2[/tex], is the equation that could represent the parabola with a vertex at (0, 0) in the standard form.

Bus route A arrives at its stop every 15 minutes. Bus route B arrives at its stop across the street every 40 minutes. If both buses are currently arriving at their stops, how many hours will pass before both buses arrive at the same time?
Answer:
120 minutes
Step-by-step explanation:
15 x 8 = 120
40 x 3 = 120
The Number of hours passed for both buses to arrive at the same time is the value of the least common multiple of the stop made by each bus. Hence, 120 minutes will pass before the buses arrive at the same time.
Bus route A = 15 minutes
Bus route B = 40 minutes
Multiples of :
15 = 15, 30, 45, 60, 75, 90, 105, 120, 13540 = 40, 80, 120, 160, 200, 240The least multiple common to both 15 and 40 is 120.
Therefore, 120 minutes will pass before both buses arrive at the same time.

Solve for the roots in simplest form using the quadratic formula:
x2 – 14x = -50
Answer:
x2-14x+58=0
Two solutions were found :
x =(14-√-36)/2=7-3i= 7.0000-3.0000i
x =(14+√-36)/2=7+3i= 7.0000+3.0000i
Step by step solution :
Step 1 :
Trying to factor by splitting the middle term
1.1 Factoring x2-14x+58
The first term is, x2 its coefficient is 1 .
The middle term is, -14x its coefficient is -14 .
The last term, "the constant", is +58
Step-1 : Multiply the coefficient of the first term by the constant 1 • 58 = 58
Step-2 : Find two factors of 58 whose sum equals the coefficient of the middle term, which is -14 .
-58 + -1 = -59
-29 + -2 = -31
-2 + -29 = -31
-1 + -58 = -59
1 + 58 = 59
2 + 29 = 31
29 + 2 = 31
58 + 1 = 59
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
Equation at the end of step 1 :
x2 - 14x + 58 = 0
Step 2 :
Parabola, Finding the Vertex :
2.1 Find the Vertex of y = x2-14x+58
Parabolas have a highest or a lowest point called the Vertex . Our parabola opens up and accordingly has a lowest point (AKA absolute minimum) . We know this even before plotting "y" because the coefficient of the first term, 1 , is positive (greater than zero).
Each parabola has a vertical line of symmetry that passes through its vertex. Because of this symmetry, the line of symmetry would, for example, pass through the midpoint of the two x -intercepts (roots or solutions) of the parabola. That is, if the parabola has indeed two real solutions.
Parabolas can model many real life situations, such as the height above ground, of an object thrown upward, after some period of time. The vertex of the parabola can provide us with information, such as the maximum height that object, thrown upwards, can reach. For this reason we want to be able to find the coordinates of the vertex.
For any parabola,Ax2+Bx+C,the x -coordinate of the vertex is given by -B/(2A) . In our case the x coordinate is 7.0000
Plugging into the parabola formula 7.0000 for x we can calculate the y -coordinate :
y = 1.0 * 7.00 * 7.00 - 14.0 * 7.00 + 58.0
or y = 9.000
Parabola, Graphing Vertex and X-Intercepts :
Root plot for : y = x2-14x+58
Axis of Symmetry (dashed) {x}={ 7.00}
Vertex at {x,y} = { 7.00, 9.00}
Function has no real roots
Solve Quadratic Equation by Completing The Square
2.2 Solving x2-14x+58 = 0 by Completing The Square .
Subtract 58 from both side of the equation :
x2-14x = -58
Now the clever bit: Take the coefficient of x , which is 14 , divide by two, giving 7 , and finally square it giving 49
Add 49 to both sides of the equation :
On the right hand side we have :
-58 + 49 or, (-58/1)+(49/1)
The common denominator of the two fractions is 1 Adding (-58/1)+(49/1) gives -9/1
So adding to both sides we finally get :
x2-14x+49 = -9
Adding 49 has completed the left hand side into a perfect square :
x2-14x+49 =
(x-7) • (x-7) =
(x-7)2
Things which are equal to the same thing are also equal to one another. Since
x2-14x+49 = -9 and
x2-14x+49 = (x-7)2
then, according to the law of transitivity,
(x-7)2 = -9
We'll refer to this Equation as Eq. #2.2.1
The Square Root Principle says that When two things are equal, their square roots are equal.
Note that the square root of
(x-7)2 is
(x-7)2/2 =
(x-7)1 =
x-7
Now, applying the Square Root Principle to Eq. #2.2.1 we get:
x-7 = √ -9
Add 7 to both sides to obtain:
x = 7 + √ -9
In Math, i is called the imaginary unit. It satisfies i2 =-1. Both i and -i are the square roots of -1
Since a square root has two values, one positive and the other negative
x2 - 14x + 58 = 0
has two solutions:
x = 7 + √ 9 • i
or
x = 7 - √ 9 • i
Solve Quadratic Equation using the Quadratic Formula
2.3 Solving x2-14x+58 = 0 by the Quadratic Formula .
According to the Quadratic Formula, x , the solution for Ax2+Bx+C = 0 , where A, B and C are numbers, often called coefficients, is given by :
- B ± √ B2-4AC
x = ————————
2A
In our case, A = 1
B = -14
C = 58
Accordingly, B2 - 4AC =
196 - 232 =
-36
Applying the quadratic formula :
14 ± √ -36
x = ——————
2
In the set of real numbers, negative numbers do not have square roots. A new set of numbers, called complex, was invented so that negative numbers would have a square root. These numbers are written (a+b*i)
Both i and -i are the square roots of minus 1
Accordingly,√ -36 =
√ 36 • (-1) =
√ 36 • √ -1 =
± √ 36 • i
Can √ 36 be simplified ?
Yes! The prime factorization of 36 is
2•2•3•3
To be able to remove something from under the radical, there have to be 2 instances of it (because we are taking a square i.e. second root).
√ 36 = √ 2•2•3•3 =2•3•√ 1 =
± 6 • √ 1 =
± 6
So now we are looking at:
x = ( 14 ± 6i ) / 2
Two imaginary solutions :
x =(14+√-36)/2=7+3i= 7.0000+3.0000i
or:
x =(14-√-36)/2=7-3i= 7.0000-3.0000i
Two solutions were found :
x =(14-√-36)/2=7-3i= 7.0000-3.0000i
x =(14+√-36)/2=7+3i= 7.0000+3.0000i

Therefore,
A triangle = three adjacent faces of the cube are intersected.
A parallelogram = two pairs of opposite faces are intersected (rhombus or rectangle)
A pentagon = the plane meets all but one face of the cube
A hexagon = the plane meets all faces of the cube
