Answer:

An exponent refers to how many times a number is multiplied by itself.

Step-by-step explanation:

For example, 2 to the 3rd (written like this: 23) means: 2 x 2 x 2 = 8. 23 is not the same as 2 x 3 = 6. Remember that a number raised to the power of 1 is itself.

Answer:

3x - 5y = - 18

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

given

3x - 5y = 10 ( subtract 3x from both sides )

- 5y = - 3x + 10 ( divide through by - 5 )

y = [tex]\frac{3}{5}[/tex] x - 2 ← in slope- intercept form

with slope m = [tex]\frac{3}{5}[/tex]

• Parallel lines have equal slopes , then

y = [tex]\frac{3}{5}[/tex] x + c ← is the partial equation of the parallel line

to find c substitute (- 1, 3 ) into the partial equation

3 = - [tex]\frac{3}{5}[/tex] + c ⇒ c = 3 + [tex]\frac{3}{5}[/tex] = [tex]\frac{18}{5}[/tex]

y = [tex]\frac{3}{5}[/tex] x + [tex]\frac{18}{5}[/tex] ← equation of parallel line in slope- intercept form

multiply through by 5 to clear the fractions

5y = 3x + 18 ( subtract 5y from both sides )

0 = 3x - 5y + 18 ( subtract 18 from both sides )

- 18 = 3x - 5y , that is

3x - 5y = - 18 ← in standard form

The two types of longitude are the Prime Meridian and the International Date Line.

The Prime Meridian is the imaginary line of 0° longitude that divides the earth into the Eastern and Western hemispheres. It passes through Greenwich, England and is the reference point for all other longitudes on the Earth’s surface.

The International Date Line is an imaginary line located on the opposite side of the Earth from the Prime Meridian at 180° longitude. It is the reference point from which we measure the date change when traveling from one side of the world to the other.

The calculation for longitude is fairly simple. Longitude is measured in degrees, with a full circle being 360°. Each degree can be divided into 60 minutes and each minute into 60 seconds. To calculate the longitude, the degree and minutes are added together and converted into decimal form. For example, if a point has a longitude of 15° 22’ 30”, the calculation would be 15 + (22/60) + (30/3600) = 15.375°.

The answers are as follows:

1 Angle Bisector Theorem

2 Sum of Adjacent Angles

3 Co-interior angle property

4 Additive law

Given:

Note: Diagram for Question is attached

1. Angle Bisector Theorem

The angle bisector is BD. Bisection entails splitting into two equal pieces. Angles 3 and 4 are therefore equal.

2. Sum of Adjacent Angles

To determine the greater angle that is created by the two adjacent angles, add the two angles together.

3. Co-interior angle property

According to the co-interior property, the sum of interior angles (on the same side) formed when a single line crosses two parallel lines is equal to 180.

4. Additive law

By applying the additive law, we can take a value away from both sides of the equation without throwing the equation out of balance. Therefore, we may take 110 out of both sides of the equation to get the final result of 70.

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.

So, the sequence is 10, 100, 1000, 10000, 100000

A pattern that multiplies each number by 10 to get the next number in the sequence would be as follows:

Start with 10.

Multiply 10 by 10 to get 100.

Multiply 100 by 10 to get 1000.

Multiply 1000 by 10 to get 10000.

Multiply 10000 by 10 to get 100000.

This pattern creates a sequence of numbers that increases exponentially, with each number being 10 times larger than the previous one. The pattern can be represented by the following rule: "Each number in the sequence is the previous number multiplied by 10."

So, the sequence is:

Given that the hypotenuse of the right triangle is as given then;

i. α = 56^o

ii. Adjacent = 2.80

iii. Opposite = 4.15

A right triangle is a type of triangle which has only one of its internal angles equal to 90^o. Thus the hypotenuse is opposite to the greatest angle, while the second long side is opposite to the greater angle, and the shortest side opposite to the measure of the least angle.

Applying the Pythagorean theorem to the triangle, we have;

i. The sum of angles in a triangle is 180^o. So that;

α + 34 + 90 = 180

α + 124 = 180

α = 56^o

ii. Let the length of the opposite side be represented by y;

   Sin θ = opposite/ hypotenuse

   Sin 34 = y/ 5

y = 5 * Sin 34

 = 2.796

The length of its opposite side is 2.80.

iii. Let the length of the adjacent side be represented by x;

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)

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]

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
