the Matrix multiplication of the given question is [tex]\left[\begin{array}{cc}-9&3\\5&-8\\\end{array}\right][/tex]

What is matrix?

The plural version of the word matrix is a matrix, which refers to the arrangements of numbers, variables, symbols, or phrases in a rectangular table with varying numbers of rows and columns. These arrays have a rectangular shape, and several operations like addition, multiplication, and transposition are specified for them. The components of the matrix are referred to as its entries or numbers. Vertical and horizontal entries in matrices are referred to as columns and rows, respectively. A matrix with m rows and n columns will contain m n entries. The uppercase letter 'A', which here stands for "matrix," Aij.

A =-1/3 [tex]\left[\begin{array}{cc}27&-9\\-15&24\\\end{array}\right][/tex]

A = [tex]\left[\begin{array}{cc}-9&3\\5&-8\\\end{array}\right][/tex]

The distance between Jasmine’s house and her grandmother’s house is 504 miles.

To find the distance, we can use this following formula:

X = V x T

Where: X = distance, V = Velocity, and T = Time

By using the following equations above, we can assume that

V x 45 = (V-4) x 70

45 V = 70 V – 280

25 V = 280

V = 11.2 mph

Now that we have the velocity, we can find the distance =

X = V x T

X = 11.2 mph x 45 minutes

X = 504 miles

Thus, the distance between Jasmine’s house and her grandmother’s house would be 504 miles

A triangle's exterior angle is the product of its interior opposing angles.

Exterior angles are those that run parallel to a polygon's exterior angles but are located outside of it. The sum of the two internal opposed angles determines the size of an outside angle.

At each vertex, there are two equivalent exterior angles.

Each vertex often only shows one external angle, though.

A triangle's exterior angles have these three essential qualities:

(1) A triangle's corresponding and exterior angles pair together to form a linear pair of angles. The inner and exterior angles therefore total up to 180 degrees.

(2) The size of a triangle's external angle is equal to the sum of its two diametrically opposed internal angles. The exterior angle theorem is another name for this property.

(3) A triangle's outside angles add up to a total of 360.

It is possible to construct a triangle whose sides are 5 cm 7 cm and 11 cm because the sum of two sides are greater than three sides.

In the given question, we have to check that it is possible to construct a triangle whose sides are 5 cm 7 cm and 11 cm.

The sum of the two sides must always be greater than the third side in order to determine whether or not the given sides may form a triangle.

To check this we firstly add the 5 and 7

5 + 7 > 11

12 > 11

Now we add 7 and 11

7 + 11 > 5

The value of the given equation with a fractional index is 15.

What are fractional indices?

We can determine how many times a term has been multiplied by itself using an index, which is a small number. Powers of a term that are fractions are known as fractional indices.

The fractional power's two components both have significance. The number's or letter's root serves as the fraction's denominator. The power to raise the answer is contained in the fraction's numerator.

For example,

A value raised to the power of ½ means we have to find the square root.

A value raised to the power of ⅓ means we have to find the cube root

Some of the rules of fractional indices are

[tex]a^{1/m} * a^{1/n} = a^{1/m + 1/n} \\\a^{1/m} / a^{1/n} = a^{1/m - 1/n} \\\a^{1/m} * b^{1/m} =( ab)^{1/m}\\\a^{1/m} / b^{1/m} =( a/b)^{1/m}[/tex]

[tex](a^\frac{1}{m}) ^\frac{1}{n} = a^\frac{1}{mn}[/tex]

For the given question,

    [tex](15^\frac{1}{5} )^5[/tex] = [tex]15^\frac{5}{5} =15^1 =15[/tex]

Therefore the value of the given equation with a fractional index is 15.

Step-by-step explanation:

Given that ∠MPN is a right angle, we know that MP and NP are perpendicular to each other. Since NP is also a perpendicular bisector of MO, it bisects MO at a 90-degree angle.

Also given that NP is a perpendicular bisector of MO, we know that NP is equidistant from M and O. Therefore, NP is the midpoint of MO and so MN = NO.

Since MP and NP are perpendicular and MN = NO, it follows that △MNP is similar to △ONP.

Therefore, we can conclude that △MNP ≅ △ONP

The point of intersection is (1, 0, -2)

To find the point where the line through (-1, 1, -8) and (5, -2, 10) crosses the ZX plane, we need to find the point on the line that has a y-coordinate of 0.

We know that the equation of a line in 3D space is given by:

P = P0 + t(P1 - P0)

where P0 is a point on the line, P1 is another point on the line, t is a scalar parameter, and P is a variable point on the line.

We can substitute in the coordinates of the two given points for P0 and P1:

P = (-1, 1, -8) + t((5, -2, 10) - (-1, 1, -8))

and set the y-coordinate to 0:

1 + t(-3) = 0

t = 1/3

so the point of intersection is:

P = (-1, 1, -8) + (1/3)((5, -2, 10) - (-1, 1, -8))

P = (-1, 1, -8) + (1/3)((6, -3, 18))

P = (-1, 1, -8) + (2, -1, 6)

P = (1, 0, -2)

So the point of intersection is (1, 0, -2)

His monthly payment, to the nearest dollar, if the loan is taken over 25 years is $1,978.54

Mortgage is a loan taken out to purchase a property. It is usually secured against the value of the property with the lender having the right to repossess the property if the loan is not repaid.

The fixed monthly payment for a mortgage can be calculated using the following formula:

Monthly Payment = [P x R(1+R)^N]/[(1+R)^N-1]

P = Principal Amount

R = Monthly Interest Rate

N = Total Number of Payments

Where Interest Rate is the interest rate per annum, Principal Loan Amount is the amount of money borrowed, and Term in Months is the duration of the mortgage loan in months.

Solution:

Monthly Payment = [$420,000 x (0.03/12)(1 + 0.03/12)^300]/[(1 + 0.03/12)^300 - 1]

Monthly Payment = $1,978.54

The end behavior of the functions g(x) and h(x) are the same and both functions approach negative infinity as x becomes large in either direction.

Generally, The end behavior of a function refers to the behavior of the function as x approaches positive or negative infinity. To compare the end behavior of g(x) and h(x), we can look at the leading term of each function, which is the term with the highest degree.

In the function g(x) = -3x^4 + 15x^3 - 12x^2 + 3x + 20, the leading term is -3x^4, so as x approaches positive or negative infinity, the function will approach negative infinity.

In the function h(x) = -3x^4 - 16x - 1, the leading term is also -3x^4, so as x approaches positive or negative infinity, the function will also approach negative infinity.

An object that appears to be identical but is really turned the opposite way in the plane perpendicular to the mirror surface is called a mirror image.

It appears as an optical phenomenon as a result of reflection from surfaces like water or mirrors. People might be able to see a reflection of themselves in the mirror behind the glass. The "mirror image" is produced when light rays strike the mirror-like surface and reflect back. One that is commonly misinterpreted is the notion that the reflection is reflected from left to right. Mirrors are turned from left to right rather than from front to back.

When looking at printed surfaces from the inside out, as well as in the reflections of mirrors and other reflecting surfaces, one may notice two-dimensional mirror images. After gazing at what is effectively a two-dimensional object when we first glance at a card, we notice a left-right reversal in the mirror when we turn the card such that the lettering is facing a mirror (like the text on a card).
