What's a rational number between 8 and 8.1
jeka94
A rational number is any number that can be written in a/b form (like a fraction). So it just can't be a repeating decimal like how pie goes on forever. So let's see. 8.05 could work. Since you could write that as 8.05 over 1 (8.05/1)

Write these numbers in size order start with the smallest
professor190 [17]
First convert all to decimal.

7/9 = 0.777
8/11 = 0.727
0.79 = 0.79
84% = 0.84
4/5 = 0.8

Now line them back up in order from least to greatest based on the decimal value.

Final answer:
8/11, 7/9, 0.79, 4/5, 84%

Identify the graph of 9X^2+4xy+5y^2-40=0 and find theta to the nearest degree.
lubasha [3.4K]

Answer:

The answer is ellipse; 23° to the nearest degree ⇒ answer (d)

Step-by-step explanation:

* At first lets talk about the general form of the conic equation

- Ax² + Bxy + Cy²  + Dx + Ey + F = 0

∵ B² - 4AC < 0 , if a conic exists, it will be either a circle or an ellipse.

∵ B² - 4AC = 0 , if a conic exists, it will be a parabola.

∵ B² - 4AC > 0 , if a conic exists, it will be a hyperbola.

* Now we will study our equation:

- 9x² + 4xy + 5y² - 40 = 0

∵ A = 9 , B = 4 , 5 = 5

∴ B² - 4 AC = (4)² - 4(9)(5) = -164 < 0

∴ B² - 4AC < 0

∴ If a conic exists, it will be either a circle or an ellipse.

* To find the type of the graph lets check;

- If A and C are nonzero, have the same sign, and are not

 equal to each other, then the graph is an ellipse.

- If A and C are equal and nonzero and have the same

 sign, then the graph is a circle.

∵ A and C have same signs and are not equal

∴ The graph is an ellipse

* If we have term xy ⇒ B ≠ 0

∴ The graph is rotate by angle Ф

* To find the angle of rotation use the rule:

- cot(2Ф) = (A - C)/B

∵ A = 9 , B = 4 , C = 5

∴ cot(2Ф) = (9 - 5)/4 = 4/4 = 1

∴ tan(2Ф) = 1

∴ 2Ф = 45°

∴ Ф = 22.5° ≅ 23° to the nearest degree

* The answer is ellipse; with angle of rotation = 23°

Jason jumps from a plane at an altitude of 1000 m. His parachute opens after 10 seconds. The graph shows the relationship betwee
Lemur [1.5K]
<h3>Answer:</h3>

600 m

<h3>Step-by-step explanation:</h3>

The slope between 1 minute and 2 minutes is ...

... (800 -500)/(2 -1) = 300 . . . . . . m/min

Thus in 20 seconds, 1/3 minute, Jason will fall ...

... (1/3 min)·(300 m/min) = 100 m

This distance is in addition to the 500 m he has already fallen in the first minute.

In 1 min 20 sec, Jason falls 500 m + 100 m = 600 m.

_____

<em>Comment on the graph</em>

We don't expect Jason's rate of fall to change dramatically at the 2-minute mark. We suspect the last point should be (2 2/3, 1000).
