Vectors and Complex numbers Part AYou drive 30 miles due east in a half hour. Then, you turn left and drive 30 miles north in 1 hour. What are your average speed andvelocity, and what are the rectangular and polar coordinates of your position?Part BYou have already travelled 30 miles east and then 30 miles north. To get back to the start, you travel 30 miles west in 1 hour and then 30 minutes south in a half hour. What are your average speed and average velocity for the whole rally?
Part A.
30 miles east in half hour next
turn left and drive 30 miles north in 1 hour
The average speed is given by
the total distance divided by the total amount of time.
In this case,
[tex]\begin{gathered} \text{average velocity=}\frac{30+30}{1.5+1} \\ \text{average velocity=}\frac{60}{2.5} \\ \text{average velocity=}24\text{ }\frac{miles}{hour} \end{gathered}[/tex]Now, the position in rectangular coordinates is (30,30)
In polar coordinates, we must find the angle theta and the lenght r.
This can be given as
[tex]\begin{gathered} r=\sqrt[]{x^2+y^2} \\ \end{gathered}[/tex]In our case x=30 and y=30, hence
[tex]\begin{gathered} r=\sqrt[]{30^2+30^2} \\ r=\sqrt[]{2\cdot30^2} \\ r=30\sqrt[]{2} \end{gathered}[/tex]On the other hand, angle theta is given by,
[tex]\theta=tan^{-1}\frac{y}{x}[/tex]hence,
[tex]\begin{gathered} \theta=tan^{-1}\frac{30}{30} \\ \theta=tan^{-1}1 \\ hence, \\ \theta=45\text{ degr}ees \end{gathered}[/tex]Therefore, in polar coordinates, point (30,30) is given by
[tex](r,\theta)=(30\sqrt[]{2},45)[/tex]Part B
Until now, we drove 30 miles east, next 30 miles north. Now, we must drive 30 miles west and 30 miles south.
Hence, we will drive 30+30+30+30=4*30=120 miles. Therefore, the average velocity is
[tex]\begin{gathered} \text{average velocity=}\frac{120}{1.5+1+1.5+1.5} \\ \text{average velocity=}\frac{120}{5.5} \\ \text{average velocity=}21.81\text{ }\frac{miles}{hour} \end{gathered}[/tex]Part A. Velocity.
Velocity is a vector. In this case, we must add to vectors:
vector V1 is given by
[tex]\begin{gathered} v_1=(\frac{30}{1.5},0) \\ \text{which is equal to } \\ v_1=(20,0) \end{gathered}[/tex]Vector V2 is given by
[tex]\begin{gathered} v_2=(0,\frac{30}{1}) \\ v_2=(0,30) \end{gathered}[/tex]then, resultant vector velocity is
[tex]\begin{gathered} v=v_1+v_2 \\ v=(20,0)+(0,30) \\ v=(20,30) \end{gathered}[/tex]Why were the colonists prepared to meet the British at the Battles of Lexington and Concord?
OA. They had organized their own sovereign governments and militias.
OB. They had feared and prepared for British efforts to seize their arms.
C. They knew that war had already been declared by British authorities.
OD. They believed that they could prevent open conflict by showing their resolve.
The British invaded Lexington and Concord with the goal of disarming any potential rebels by taking their guns.Instead, the Revolutionary War's opening conflict was precipitated by their activities.
Why did the battle of Lexington and Concord happen?
The American Revolutionary War began on April 19, 1775, with the Battles of Lexington and Concord (1775-83).Residents of the 13 American colonies and the British government had been at odds for many years, especially in Massachusetts.Hundreds of British soldiers marched from Boston to nearby Concord that evening, April 18, 1775, in attempt to take an arsenal.The Redcoat column was about to be intercepted when Paul Revere and other horsemen raised the alarm.The conflict began with an altercation on the Lexington town green, and soon the British were fleeing under heavy fire.After numerous additional conflicts, the colonists finally achieved official independence in 1783. Battles of Lexington and Concord's lead-upGreat Britain began taking a number of actions in 1764 to increase revenue from its 13 American possessions.The colonists revolted against "taxation without representation" as a result of many of these laws, such as the Sugar Act, Stamp Act, and Townshend Acts.One of the biggest hubs of opposition was Boston, the location of the 1770 Boston Massacre and the 1773 Boston Tea Party.In June 1774, King George III of Britain increased the military presence there and closed the city's harbor until the colonists paid for the tea that had been poured overboard the year before.The British Parliament soon after declared that Massachusetts was in full-fledged rebellion. Paul Revere never yelled the infamous remark that was later ascribed to him ("The British are coming!") as he traveled from town to town on April 18, 1775, at midnight.Considering that large numbers of British soldiers were skulking in the countryside of Massachusetts, the operation was designed to be carried out as covertly as possible.Colonial Americans also thought of themselves as British at that time.A source inside the British high command informed Joseph Warren, a physician and Sons of Liberty member, on April 18 that Redcoat troops would march on Concord that evening.Paul Revere, a silversmith, and William Dawes, a tanner, were sent as two messengers by Warren to inform the populace. In the event that one of them was captured, they took separate paths.To reach Charlestown, where fellow Americans were waiting for a signal regarding the movement of British troops, Revere traveled across the Charles River by boat.The Old North Church steeple in Boston, Massachusetts, was pointed out to the patriots to be seen because it was the highest point in the city.The British were coming by land if there was even a single lantern hanging in the steeple.In the event that there were two, the British arrived by sea.The secret signal was commemorated by American poet Henry Wadsworth Longfellow in his poem "Paul Revere's Ride," where he stated: "If by land, one; if by sea, two; and I on the other shore, ready to ride and give the alarm Through every Middlesex village and farm, For the country men to be up and to arm."Dawes left Boston and made his way along the Boston Neck peninsula as Revere completed his mission in Charlestown.A few miles east of Concord, where revolutionary leaders John Hancock and Samuel Adams had taken refuge, the two came together in Lexington.Revere and Dawes set out again after successfully convincing those two to go.They encountered Samuel Prescott, a third rider, who traveled all the way to Concord by himself.A British patrol arrested Revere, while Dawes escaped.

find the x and the y intercept there should be 2 ordered pairs for the each solution
We have the line in standard form:
[tex]4x+5y=-20[/tex]We have to find the 2 intercepts.
The y-intercept correspond to the value of the line when x=0, so we can find the value of y that correspond to x=0 replacing x in the equation and solving for y:
[tex]\begin{gathered} 4x+5y=-20 \\ 4(0)+5y=-20 \\ 5y=-20 \\ y=-\frac{20}{5} \\ y=-4 \end{gathered}[/tex]Then, the ordered pair for the y-intercept is (0,-4).
In the case of the x-intercept the concept is equivalent but the coordinate that has a value of 0 is y. So we will replace y with 0 in the equation and solve for x:
[tex]\begin{gathered} 4x+5(0)=-20 \\ 4x=-20 \\ x=-\frac{20}{4} \\ x=-5 \end{gathered}[/tex]Then, the ordered pair for the x-intercept is (-5,0).
We can graph the line and its intercepts as:

show algebraically that 0.681 can be written as 15/22
The expression 0.681 can be written as 15/22 because 0.681 approximates to 15/22
How to show that the expressions are equivalent?The expressions are given as
0.681 and 15/22
Start by converting 0.681 to fraction
So, we have the following equation
0.681 = 681/1000
Multiply the fraction by 1
So, we have
0.681 = 681/1000 x 1
Rewrite 1 as 22/22
0.681 = 681/1000 x 22/22
Switch the numerator and the denominator
So, we have
0.681 = 681/22 x 22/1000
Simplify
0.681 = 681/22 x 11/500
Multiply 681 by 11
So, we have
0.681 = 7491/22 x 1/500
Divide 7491 by 500
So, we have

What are Decimals?A decimal numeral is a broad term for a number's notation using the decimal numeral system. Sometimes a decimal separator is used to identify decimals. Integer and non-integer numbers are often expressed using the decimal numeral system. The Hindu-Arabic numeral system has been expanded to include non-integer values. Term "terminating decimals" refers to decimal numerals in this context that have a predetermined number of non-zero digits following the decimal separator. An infinite decimal that, after a certain point, repeats the same digit sequence endlessly is said to be repeating. If and only if it has a finite number of non-zero digits or is a repeating decimal, an infinite decimal can be used to represent a rational number, the product of two integers.Therefore,
-8/5 = -1.6 …............ Number 3
-1.7 …............ Number 2
-30/-25 = 6/5 = 1.2 …............ Number 4

Answer:
2829.13 km.
Explanation:
If the radius of the Earth is 6370 km, the distance of the segment CD is also 6370 km.
Then, the sides of the rigth triangle are:
CB = 6370 km
AC = AD + DC
AC = 600 km + 6370 km
AC = 6970 km
AB = x
So, using the Pythagorean theorem we can calculate the value of x as follows:
[tex]\begin{gathered} AB=\sqrt[]{(AC)^2-(CB)^2} \\ x=\sqrt[\square]{6970^2-6370^2} \end{gathered}[/tex]Because AC is the hypotenuse and CB is on the legs of the triangle.
