Answer 1

Answer:

A. The constant ratio of y/x is 12/5

Step-by-step explanation:

Answer 2

The ratio of y to x is constant which is 12/5. Hence option A is the correct option.

What is a constant?

The term "constant" has several meanings in mathematics. When used as a noun, it can have any of the following two meanings: a constant, clearly defined number or another immutable mathematical object.

Given table is

x y

5/6 2

25/6 10

125/6 50

625/6 250

When x = 5/6 and y = 2:

x/y = (5/6)/2 = 5/12

∴y/x = 5/12

When x = 25/6 and y = 10:

x/y = (25/6)/10 = 25/60 = 5/12

∴y/x = 5/12

When x = 125/6 and y = 50:

x/y = (125/6)/50 = 125/300 = 5/12

∴y/x = 5/12

When x = 625/6 and y = 250:

x/y = (625/6)/250 = 625/1800 = 5/12

∴y/x = 5/12

An airplane travels about 1,500 Km in a straight line between Toronto and Winnipeg. However, the plane must climb to 10,000 m during the first 200 Km, then it must descend 10,000 m during the final 300 Km.

a) How much distance do the climb and descent add to the flight?
b) The airplane averages a speed of 600 km/h. Do climbing and descending 10 000 m add hours, minutes of second to the flight? Explain.

Please help I do not understand how to do this.

Answers

Answer:416

Step-by-step explanation: Based on the given problem above, it requires a trigonometric solution. So here it goes:

The climb distance is:200 * Sec [ArcTan [10/200]] = 10√ 401 km

and the decent distance is:300 * Sec [ArcTan [10/300]] = 10√901 km

So add the given results above with 500 km and this will be the additional distance that plane moves through the air.

The answer would be in the unit meters.

((10√401 +10√901−500)∗1000)=416 meters

Hope this is the answer that you are looking for.

Answer:

32 (if the "2" in the parenthesis is just 8 - 2 and not 8(-2)

Step-by-step explanation:

Note that you can solve this by using the method PEMDAS.

Solve the parentheses first:

21 + 3 + ( 8 ) ——— if you look closely in the parentheses (8 - 2 + 2) you should see that (- 2 + 2) is the same thing as (2 - 2) so you would be left with 8 inside your parentheses.

Combine like terms (add all the values):

21 + 3 + 8
= 24 + 8
= 32

21 + 3 + ( 8 - 2 + 2 ) = 32

Angles in a triangle sum up to 180°, so:

180° = 58° + 58° + m∠3
