To find the average speed of an object, we find the change in distance divided by the time over which that change occurs. For the instantaneous speed, we must make the time interval very _______, so that the speed does not change appreciably.
To find the instantaneous speed of an object, we must make the time interval very small, so that the speed does not change appreciably.
How to find the speed?
Speed is a scalar quantity which tells how fast an object is moving, regardless of its direction.
To find the instantaneous speed of an object, we must make the time interval very short, so that the speed does not change appreciably. The formula for the instantaneous speed of an object is given by the limit as time approaches zero of the change in distance divided by the time over which that change occurs. The formula for average speed is simply the total distance traveled divided by the total time elapsed.

What is an angle that is adjacent to ∠CED?
The angle that is adjacent to the angle CED is the angle DEA.
What are adjacent angles?When two angles have a similar vertex and side, they are referred to as neighbouring angles. The vertex of an angle is the point at which the rays that make up its sides come to an end. When adjacent angles have a same vertex and side, they can be a complimentary angle or supplemental angle.
An adjacent angle is complementary to another if the total of its adjacent angles is 90 degrees.
When the total of two adjacent angles is 180 degrees, they are supplementary to one another.
Two angles are said to be adjacent angles when they share a common vertex.
In the given figure the angle that shares the common vertex to angle CED is angle DEA.

Solve what is in the attatchment!!
the measurement of the ∠R will be 101 degrees.
What is a parallelogram?A quadrilateral with the opposing sides parallel is called a parallelogram (and therefore opposite angles equal). A parallelogram with all right angles is known as a rectangle, while a quadrilateral with equal sides is known as a rhombus.
Given TPRS is a parallelogram. in that ∠T = (4x +1) and ∠S = (3x +4)°
Since in a parallelogram, opposite angles are equal Thus,
∠P = ∠S = 3x + 4
∠R = ∠T = 4x +1
Since we know the sum of all angles of a quadrilateral is 360°
3x +4 + 4x +1 + 3x +4 + 4x +1 = 360
14x + 10 = 360
14x = 350
x = 350/14
x = 25
Thus,
∠R = 4x +1
∠R = 4 *25 + 1
∠R = 101°
therefore, the measurement of the ∠R will be 101 degrees.

(200 - 100√2) / 16 is the rectangular form of the product c1*c2 for an equilateral triangle's vertices.
What is triangle?A triangle is a three-sided polygon that is sometimes (but not always) referred to as the trigon. Every triangle has three sides and three angles, which may or may not be the same.
Here,
An equilateral triangle is a triangle with three equal sides. If 3-2i, 6-i, and c form the vertices of an equilateral triangle, then the distance between 3-2i and 6-i is equal to the distance between 3-2i and c.
The distance between two complex numbers a + bi and c + di can be found using the formula:
√((c - a)² + (d - b)²)
So, the distance between 3-2i and 6-i is:
√((6 - 3)² + (-1 - (-2))²) = √((3)² + (1)²) = √(9 + 1) = √10
And the distance between 3-2i and c is:
√((c - 3)² + (c - (-2))²) = √((c - 3)² + (c + 2)²)
Since these distances must be equal, we have:
√((c - 3)² + (c + 2)²) = √10
Squaring both sides:
(c - 3)² + (c + 2)² = 10
Expanding both sides:
c² - 6c + 9 + c² + 4c + 4 = 10
Combining like terms:
2c² + 10c + 5 = 10
Subtracting 10 from both sides:
2c² + 10c - 5 = 0
This is a quadratic equation, which can be solved using the quadratic formula:
c = (-b ± √(b² - 4ac)) / 2a
Where a = 2, b = 10, and c = -5. Plugging these values into the formula:
c = (-10 ± √(10² - 4 * 2 * -5)) / 2 * 2
c = (-10 ± √(100 + 40)) / 4
c = (-10 ± √(140)) / 4
c = (-10 ± 10√2) / 4
So there are two complex solutions, c1 = (-10 + 10√2) / 4 and c2 = (-10 - 10√2) / 4.
The product of these two solutions is:
c1 * c2 = ((-10 + 10√2) / 4) * ((-10 - 10√2) / 4)
= (100 - 100√2 + 100) / 16
= (200 - 100√2) / 16
(200 - 100√2) / 16 is the answer in rectangular form for the product c1*c2 for the vertices of an equilateral triangle.

when the two countries did not specialize, the total production of chinos was 23 million pairs per day, and the total production of pistachios was 68
The total production of both countries when they did not specialize was 91 million / day.
Given the information that when the two countries did not specialize, the total production of chinos was 23 million pairs per day, and the total production of pistachios was 68, we can calculate the total production of both countries with the following equation:
Total Production = Chinos (23 million pairs / day) + Pistachios (68 million / day)
Therefore, the total production of both countries when they did not specialize was 91 million / day. This can be calculated as:
Total Production = 23 million pairs + 68 million = 91 million / day
Hence, the total production of both countries when they did not specialize was 91 million / day. This calculation can be represented by the following formula:
Total Production = Chinos (x) + Pistachios (y)

Step-by-step explanation:
Suppose that you have at your disposal a software package that solves a square nonsingular system of equations Cx=d. Assume that the package either finds the unique solution of Cx=d or terminates with an error message if C is singular. Given an m×n matrix A of rank n and an m -vector b, briefly describe in words how you would use the package to find whether or not the equations Ax=b are compatible, and if they are, compute a solution x. Comment briefly on the uniqueness of a solution if one exists.
The equations Ax = b are not compatible.
What do you mean by equation?It is represented by an equal sign (=) and is used to solve for unknown values or to describe relationships between variables. Equations can be simple or complex, involving basic arithmetic operations or advanced mathematical concepts like trigonometry and calculus.
An equation can be used to solve for a single unknown value, for example, the equation 2x + 3 = 7 can be solved for x by subtracting 3 from both sides, giving us 2x = 4 and then dividing both sides by 2, giving us x = 2. In this example, x = 2 is the solution to the equation.
To determine whether the equations Ax = b are compatible and to compute a solution x, you would first form the augmented matrix [A|b]. Then, you would perform row operations on [A|b] to reduce it to an upper triangular matrix [C|d]. Finally, you would use the software package to solve the square system of equations Cx = d.
If the software terminates with an error message, it means that C is singular, and the equations Ax = b are not compatible. If the software finds the unique solution of Cx = d, it means that the equations Ax = b are compatible and that the solution x is unique. However, it is important to note that the uniqueness of the solution depends on the rank of A being equal to n. If the rank of A is less than n, the equations are not compatible, and if the rank of A is greater than n, the equations have infinitely many solutions.
