The vector and parametric equations are r(t) = [t/2, (4t/3 - 1), (1 - 3t/4)] and x = t/2, y = -1 + 4t/3, z = 1 - 3t/4.
We have P(0, -1, 1), Q(1/2, 1/3, 1/4)
We have to find a vector equation and parametric equations for the line segment that joins P to Q.
Vector equation of a line segment joining the points with position vectors r0 and r1 is given by
r =(1 - t)r0 + tr1
Where, t ∈ [0, 1]
Here, r0 = (0, -1, 1) and r1 = (1/2, 1/3, 1/4)
So, r(t) = (1 - t)(0, -1, 1) + t(1/2, 1/3, 1/4)
r(t) = [((1 - t)(0) -1(1 - t) + 1(1 - t)] + [t/2, t/3, t/4]
r(t) = [0, (t - 1), (1 - t)] + [t/2, t/3, t/4]
On simplification,
r(t) = [(t/2 + 0), (t + t/3 - 1), (1 - t + t/4)]
r(t) = [t/2, (4t/3 - 1), (1 - 3t/4)]
Where, t ∈ [0,1]
The parametric equations for the line segment are
x = t/2, y = -1 + 4t/3, z = 1 - 3t/4
Where, t ∈ [0, 1]
Therefore, the vector and parametric equations are r(t) = [t/2, (4t/3 - 1), (1 - 3t/4)] and x = t/2, y = -1 + 4t/3, z = 1 - 3t/4.

What is the interior angle?Angles inside a polygon are referred to as interior angles. A triangle, for instance, has three internal angles. Interior angles are sometimes defined as "angles confined in the interior area of two parallel lines when they are crossed by a transversal."
Given:
(2). The exterior angle is 52°.
So, the sum of all the interior angles in the polygon = (5 - 2)180
x + (180 - 52) + 2x + x + 2 + 90 = 560
4x + 208 = 560
4x = 352
x = 88

how many seconds in 4.571 billion years
4.571 billion years is equals to 1.4415 × 10⁷ seconds.
To calculate the number of seconds in 4.571 billion years, we first need to determine how many seconds there are in a year. There are 60 seconds in a minute, 60 minutes in an hour, 24 hours in a day, and 365 days in a year. Multiplying these together gives us 31,536,000 seconds in a year.
Next, we multiply the number of seconds in a year by the number of years in 4.571 billion years. This gives us:
31,536,000 seconds/year x 4,571,000,000 years = 1.4415 × 10¹⁷ seconds
Therefore, there are approximately 1.4415 × 10¹⁷ seconds in 4.571 billion years.
It's worth noting that this calculation assumes a standard year of 365 days. In reality, a year is slightly longer than 365 days, and so the actual number of seconds in 4.571 billion years would be slightly higher. Nonetheless, this calculation provides a good approximation.

The diagram below shows a rectangular prism made up of
inch cubes.
1. How many unit cubes whose dimensions are 3/5 inch fill up the rectangular prism?
_________
2. Find the total volume, in cubic inches, represented in the diagram.
_______ cubic inches
The number of unit cubes whose dimensions are 3/5 inch fill up the rectangular prism is (125/27)abc.
The total volume, in cubic inches, is represented in the diagram n cubic inches.
What is a cube?A cube is a three-dimensional object who has six faces.
Since each side of the unit cube has a length of 1 inch, the number of unit cubes that fill up the rectangular prism is equal to its volume in cubic inches. If the rectangular prism has dimensions a x b x c inches, then its volume is V = abc cubic inches.
Now, we need to find how many unit cubes whose dimensions are 3/5 inch fill up the rectangular prism. First convert the dimensions of the unit cube and the rectangular prism to a common unit, such as inches. Since 1 inch = 5/3 unit cubes, each side of the unit cube has a length (3/5) inch. Therefore, each side of the rectangular prism has dimensions (5a/3) x (5b/3) x (5c/3) unit cubes.
To find the number of unit cubes that fill up the rectangular prism, we can divide its volume (abc cubic inches) by the volume of each unit cube, which is (3/5)³ cubic inches. Thus, the number of unit cubes whose dimensions are 3/5 inch that fills up the rectangular prism is:
(abc) / [(3/5)³] = (125/27)abc
To find the total volume represented in the diagram, we need to add up the volumes of all the unit cubes shown in the diagram. Since we don't know the dimensions of the rectangular prism, we can't calculate its volume directly.
Therefore, the total volume represented in the diagram is n cubic inches.

The residents of a city voted on whether to raise property taxes the ratio of a yes votes to no votes was 5 to 4 if there were 4923 total votes how many yes votes were there ?
Answer:
2,735 yes votes
Step-by-step explanation:
First we have too determine the ratio of yes votes to the total number of votes.
We can rationalize thus
If there are 5 yes votes and 4 no votes, the total number of votes = 5+ 4 = 9
So 5/9th of the total votes are yes votes
If the total number of votes = 4923 , number of yes votes = 5/9 x 4923
= 2,735 yes votes ANSWER
We can check to see if our reasoning is correct:
Total number of no votes = 4923 - 2735 = 2188
Yes votes to Nay votes = 2735 : 2188
As a fraction:
2735 / 2188 = 1.25

Which quadrilateral has diagonals that are alwaysperpendicular bisectors of each other?1) square 2) rectangle 3) trapezoid4) parallelogram
The quadrilateral with diagonals that are always perpendicular bisectors of each other is a square. Correct option is 1.
In a square, the diagonals bisect each other at right angles, which means they intersect at a 90-degree angle. Moreover, since a square has four congruent sides and four right angles, the diagonals are also congruent. Thus, each diagonal is a perpendicular bisector of the other diagonal, splitting it into two equal segments.
In contrast, a rectangle has diagonals that bisect each other, but they are not always perpendicular. A trapezoid has only one pair of opposite sides that are parallel, and its diagonals do not bisect each other.

The slope of the line is -1/4, So correct option is B.
Describe Slope?It is defined as the ratio of the change in the vertical coordinate (y) to the change in the horizontal coordinate (x) between any two points on the line or curve. The letter m is typically used to indicate a line's slope.
The formula for the slope of a line between two points (x1, y1) and (x2, y2) is:
m = (y2 - y1) / (x2 - x1)
The slope can be positive, negative or zero, depending on the direction of the line. A positive slope indicates that the line is moving upwards from left to right, while a negative slope indicates that the line is moving downwards from left to right. A slope of zero indicates that the line is horizontal.
The slope of a line passing through two points (x1, y1) and (x2, y2) is given by:
slope = (y2 - y1)/(x2 - x1)
Using the coordinates (-4, 2) and (4, 0), we have:

As a rule of thumb, altitude corrections of less than 100 feet should be corrected by using "less than a full bar width on the attitude indicator".
C. is the answer.
How should altitude corrections of less than 100 feet be corrected?The attitude indicator (also known as an artificial horizon) is a key instrument in an aircraft that displays the aircraft's pitch and bank attitude. The instrument typically consists of a gyro that indicates the aircraft's attitude relative to the horizon.
When flying an aircraft, it's important to maintain a specific altitude, and to make adjustments as needed to stay on course. The altitude is typically measured in feet above sea level, and can be affected by a number of factors, such as temperature, pressure, and wind.
As a rule of thumb, altitude corrections of less than 100 feet can be corrected using the attitude indicator by making adjustments that are less than a full bar width on the instrument.

4) While designing a new dessert menu, the manager of a restaurant offered customers a
coupon in exchange for completing a brief survey about their favorite desserts. 20 of the
customers accepted the offer.
) Is this a random sample of the restaurant's customers?
YES/NO
This is not a random sample of the restaurant's customers.
Why is this not a random sampling ?The offer of a coupon in exchange for completing a brief survey about favorite desserts may bias the sample and result in a non-random sample of the restaurant's customers.
Only those customers who were interested in the coupon may have participated in the survey, which may not be representative of the overall customer population. Additionally, those who chose to participate may have different tastes and preferences compared to those who did not participate.
