X(t) = 2-t, Y(t) = 5-t, and Z(t) = 0 are the parametric equations for the line passing through (2, 5, 0) and being perpendicular to both i+j and j k. The line has symmetric equations x+2 = -(y + 5) and z = 0, or x+2 = -(y + 5) = z.

As x(t) = 2-t, y(t) = 5-t, and z(t) = 0, the parametric equations of the line passing through (2, 5, 0) and perpendicular to both i+j and j k can be written. The x, y, and z coordinates of the line are defined by these equations in terms of the parameter t. It is possible to write the line's symmetric equations as x+2 = -(y + 5) and z = 0, or as x+2 = -(y + 5) = z. These equations define the line as the collection of all points (x, y, and z) that concurrently meet both equations. The line goes through the point and is perpendicular to both i+j and j k.

Answer: One way that Olivia might have found a combination of two transformations to move figure ABCDE onto figure A'B'C'D'E' is by using a combination of translations and rotations.

A translation is a type of transformation that moves a figure a certain distance in a specified direction, without changing its size or orientation. A rotation is a type of transformation that turns a figure about a fixed point, called the center of rotation, by a certain angle.

Olivia might have first translated figure ABCDE to a new location and then rotated it about a point to match the orientation of A'B'C'D'E'. For example, she could have translated figure ABCDE so that one vertex coincides with a corresponding vertex in A'B'C'D'E', and then rotated it about that common vertex so that the sides match up.

Alternatively, Olivia might have first rotated figure ABCDE to a new orientation and then translated it to the final position. The sequence of transformations could have been different, but the end result would still be figure ABCDE matching the orientation and position of A'B'C'D'E'.

Step-by-step explanation:

( 4x + 1 ) ° = ( 3x + 4 )°

Opposite side of parallelogram are always equal ...

4x + 1° = 3x + 4°

4x - 3x = 4° - 1°

x = 3°

The measure of angle R from the given parallelogram TPRS is 101°.

A parallelogram is a special kind of quadrilateral that is formed by parallel lines. The angle between the adjacent sides of a parallelogram may vary but the opposite sides need to be parallel for it to be a parallelogram. A quadrilateral will be a parallelogram if its opposite sides are parallel and congruent.

Given that, TPRS is a parallelogram.

Here, ∠T=(4x+1)° and ∠S=(3x+4)°

The sum of adjacent angles of a parallelogram is 180°.

∠T+∠S=180°

(4x+1)°+(3x+4)°=180°

7x+5=180

7x=175

x=175/7

x=25°

So, ∠T=(4x+1)°=4×25+1=101°

∠T=∠R=101° (Opposite angles of parallelogram are equal)

Therefore, the measure of angle R is 101°.

The more money will be earned for job B.

Subtraction can be done for any numbers or algebraic expressions. It is the process of taking out certain value from a given amount of number.

For Job A :

Salary = $51,000

Distance = 9 miles from home

Total distance needed to travel to and back from job in a day = 18 miles

Number of working days in a year = 260

Number of working days in a year after vacation = 260 - (12% × 260) = 228.8 days

Total distance for working days in a year = 228.8 × 18 = 4118.4 miles

Mileage on his car = 24 miles per gallon

Amount of gas for 24 miles = 1 gallon

Amount of gas for 4118.4 miles = 171.6 gallon

Gas price for 1 gallon = $5.25

Gas price for 171.6 gallon = 171.6 × $5.25 = $900.9

Net salary after gas price = $51,000 - $900.9 = $50,099.1

For Job B :

Salary = $53,000

Distance = 22 miles from home

Total distance needed to travel to and back from job in a day = 44 miles

Number of working days in a year after vacation = 260 - (8% × 260) = $239.2 days

Total distance for working days in a year = 239.2 × 44 =  10,524.8 miles

Mileage on his car = 24 miles per gallon

Amount of gas for 24 miles = 1 gallon

Amount of gas for 10,524.8 miles = 438.533 gallon

Gas price for 1 gallon = $5.25

Gas price for 171.6 gallon = 438.533 × $5.25 = $2302.3

Net salary after gas price = $53,000 - $2302.3 = $50,697.7

The net salary after gas price is higher for job B.

Hence Net salary after gas price is higher for job B.

Answer:

The investment will be worth $16898.67 after 17 years, compounded semiannually at 3.3% per year.

Step-by-step explanation:

The compound interest formula is:

A = P * (1 + (r/n))^(nt)

where

A is the amount of the investment after t years,

P is the principal amount (9070),

r is the annual interest rate (3.3%),

n is the number of times the interest is compounded per year (2),

t is the number of years (17).

Using the formula:

A = 9070 * (1 + (0.033/2))^(2 * 17)

A = 9070 * (1.0165)^34

A = 9070 * 1.882611

A = 16898.67 to the nearest cent.

So the investment will be worth $16898.67 after 17 years, compounded semiannually at 3.3% per year.

The smallest angle is 5° when each of those angles was divided into 5 equal parts.

In Geometry, an angle is a figure which is produced by two rays, which share a common point called a vertex. The two rays stand in for the angle's two sides. The Roman word "Angulus," which means "corner," is where the term "angle" originates. The intersection of two curves in this plane results in the angles. Angles of several kinds can be generated on a planar surface. As follows:

Acute Angle

Obtuse Angle

Right Angle

Reflex Angle

Straight Angle

Full Angle

An angle greater than 90° but less than 180°  is referred to as a "obtuse angle."  An obtuse angle is between a right angle and a straight angle.

Now in this question,

Starting with an obtuse angle of 150°, bisecting it gives two angles of 75° each.

Trisecting each of these angles gives three angles of 25° each.

Dividing each of these angles into 5 equal parts gives angles of 5° each.

Therefore, the smallest angle is 5°.

The answers for demand function are a) p(x) = -0.0006q + 15 and b) the price at which the demand will reach 20000 units put q = 20000, is $3

A demand function is a mathematical equation which expresses the demand for a product or service as a function of its price.

Given that, the demand function for a certain product is known to be linear.

When the price of the product is $12, the number of units sold is 5000.

But if the price of the product is $9, the number of units sold is 10000.

We need to find the demand function, expressed as price p in terms of quantity q and the price at which the demand will reach 20000 units.

a) P(x) can be calculated using point slope equation given:

Price is $12 for 5000 units sold. A decrease in price to $9 increases units sold to 10000.

Slope = Δ price / Δ units = 9-12 / 10000 - 5000

= -3 / 5000 = -0.0006

p(q) = m(q - x₁) + p₁

= -0.0006(q-5000) + 12

=  -0.0006q + 3 + 12

=  -0.0006q + 15

Therefore, the demand function is p(x) = -0.0006q + 15

b) To find the price at which the demand will reach 20000 units put q = 20000, put q = 20000

p(x) = -0.0006 × 20000 + 15

= -12 + 15

= 3

Therefore, the price at which the demand will reach 20000 units put q = 20000, is $3

Hence, the answers for demand function are a) p(x) = -0.0006q + 15 and b) the price at which the demand will reach 20000 units put q = 20000, is $3

The line has a slope of - 3/4.

The line has a slope of 3/4.

Step-by-step explanation:

To determine the slope of a line passing through two points, you can use the formula:

Slope = (y2 - y1) / (x2 - x1)

Using the points (-6, 8) and (-3, 4), the slope would be:

Slope = (4 - 8) / (-3 - (-6)) = -4 / 3 = -4/3

So, the line has a slope of -4/3. The other statements in the list are not necessarily true based on the given information.

The features of the sine function in this problem are given as follows:

The equation is given as follows:

For which the parameters are given as follows:

The function has a minimum value of -6 and a maximum value of -2, for a difference of 4, hence the amplitude is given as follows:

2A = 4.

A = 2.

Without vertical shift, a function with amplitude of 2 would oscillate between -2 and 2, while this one oscillates between -6 and -2, hence the vertical shift is given as follows:

D = -4.

The shortest distance between repetitions can be given by 2 - (-1) = 3, hence the period is of 3 units and the coefficient B is given as follows:

2π/B = 3

B = 2π/3.

The function is at it's midline at the origin, hence it has no phase shift, and thus the equation is given as follows:

y = 2sin(2πx/3) - 4.

To calculate the carpenter's earnings, separate the regular work hours from the overtime hours. Compute earnings for both from their respective rates and add them together. Multiply by the number of days worked and finally, by the total number of weeks.

In order to calculate the earnings of a carpenter during a 10-week period, we must consider how many hours were worked at regular and overtime rates. During the weekdays, the carpenter worked 9 hours per day. The first 8 hours were paid at the regular rate, and the remaining 1 hour was considered overtime. On Saturdays, the carpenter worked 4 hours at the regular rate as it didn't supersede the 8-hour workday.

So, on weekdays, he earned: 8 hours * $30 + 1 hour * $45. On Saturdays, his earnings were 4 hours * $30. To find the weekly earnings we add weekday and Saturday earnings, then multiply by 5 (for weekdays) and add 1 Saturday, then multiply the total earnings by 10 weeks. Using these computations, we are able to find the total amount earned by the carpenter.

The correlational hypothesis is a type of research hypothesis that proposes a relation between two variables.

Hypothesis proposes that there is a relationship or association between two variables, known as the independent and dependent variables.

The relation between the two variables can be positive or negative. A positive relation means that as the independent variable increases, the dependent variable also increases.

On the other hand, a negative relation means that as the independent variable increases, the dependent variable decreases.

The strength of the relation can be determined by calculating the correlation coefficient, which is a numerical representation of the strength of the relation between two variables.

In the mathematical representation of a correlational hypothesis, the equation
