Abcd Is A Parallelogram Determine The Length Of BEA)51 UnitsB)102 Units C)96 UnitsD) -11 Units

Answers

Answer 1

Answer:

  B)  102 units

Step-by-step explanation:

The diagonals of a parallelogram bisect each other. This means ...

  BE = ED

  3 -9x = -8x +14

  -11 = x . . . . . . . . . . . . add 9x -14

  BE = 3 -9x = 3 -9(-11) = 3 +99

  BE = 102 units

Without graphing, classify the system of equations as either consistent or inconsistent.
−7x+8y=9

21x/8−3y=−6

Answers

How you know if a system is consistent or inconsistent or dependent without graphing:

If a consistent system has a infinite number of solutions, it is dependent. When you graph the equation, both equations represent the same line. If a system has no solution, it is said to be inconsistent. If the graphs of the lines do not intersect, the graphs are parallel and there is no solution.

What is the nth term rule of the quadratic sequence

Answers

Answer:

[tex]n^2 -3n - 6[/tex]

Step-by-step explanation:

Looking at the image attached, you must first work out the difference between each term. This is +0, +2, +4, +6, +8, +10 (shown in orange).

Because you now have a linear sequence, the difference is now the same each time. This is +2 (shown in blue).

Because the original sequence is a quadratic, you have to halve the second difference (the +2). This means that the value of [tex]n^2[/tex] is 1, so 1[tex]n^2[/tex] or just [tex]n^2[/tex] .

If you write out the values of [tex]n^2[/tex], you can work out how much more you need to add or take away. For example, take the first three terms in the sequence.

n = 1, 2, 3

x = -8, -8, -6

[tex]n^2[/tex] = 1, 4, 9

Work out the difference between [tex]n^2[/tex] and x:

1 - -8 = 9

4 - -8 = 12

9 - -6 = 15

This gives you yet another linear sequence, 9, 12, 15.

Working out the formula for this, the difference is 3 each time, so it is 3n. The first value of n is 1, so 3n is 1. The difference is 6, so the formula for this linear sequence is 3n + 6.

Because [tex]n^2[/tex] is greater than x, you need to take 3n + 6 away from [tex]n^2[/tex].

This gives [tex]n^2[/tex] - (3n+6), so the final answer is:

[tex]n^2[/tex] - 3n - 6.

Technology required. A plane leaves the ground with an elevation angle of 6 degrees.
The plane travels 10 miles horizontally.
a. How high is the plane at the time?
b. What is the distance of the plane's path?
Round answers to the nearest tenths.
How high is the plane at this time?
miles
What is the distance of the plane's path?
miles

Answers

The height of the plane at that time is 1.1 miles

The distance of the plane's path is 10.1 miles

The situation forms a right angle triangle.

Using trigonometric ratio,

tan 6° = opposite / adjacent

The height of the plane is the opposite side of the triangle. The adjacent

side is the distance travelled horizontally. Therefore,

tan 6° = h / 10

cross multiply

h = 10 tan 6°

h = 10 × 0.10510423526

h = 1.05104235266

height of the plane at that time = 1.1 miles

The distance of the plane path is the hypotenuse of the triangle formed.

Therefore,

c² = a² + b²

c² = 10² + 1.1²

c = √101.21

c = 10.0603180864

c = 10.1  miles

plane's path = 10.1 miles

A flight from Boston to London took only 5 hours because of a strong tailwind. The flight back to Boston against the same wind took 6 hours. What was the speed of the wind if the speed of the plane in still air is 550 mph?

Answers

Step-by-step explanation:

let v is the speed of the wind,

the equation of the speed:

(550 + v ) × 5 = (550 - v) × 6

2750 +5v = 3300 - 6v

11v = 3300 - 2750

11v = 550

v = 550/11

v = 50

therefore, the speed of the wind =

50 mph

Step-by-step explanation:

v = speed of the wind

5(550 + v) = 6(550 - v)

2.750 + 5v = 3.330 - 6v

5v + 6v = 3.300 - 2.750

11v = 550

v = 550 ÷ 11

v = 50mph
