Answer:

  • jet in still air: 712 mi/h
  • jetstream rate: 50 mi/h

Step-by-step explanation:

The relation between speed, time, and distance is ...

  speed = distance/time

Against the wind, the speed is ...

  (3310 mi)/(5 h) = 662 mi/h

With the wind, the speed is ...

  (3810 mi)/(5 h) = 762 mi/h

The jet stream adds to the speed in one direction, and subtracts in the other direction, so the difference in travel speeds is twice the speed of the jet stream:

  (762 mi/h -662 mi/h)/2 = jet stream speed = 50 mi/h

__

The speed of the plane is the average of the two speeds, or the sum of jet stream speed and the lower speed, or the difference of the higher speed and the jet stream speed. Any of these calculations will give the plane's speed in still air:

  (762+662)/2 = 662 +50 = 762 -50 = 712 . . . mi/h

Alexxx [7]

Answer:

Step-by-step explanation:

It represents a linear function because there is a constant rate of change.

Step-by-step explanation:

Since, if the rate of change for y ( output value ) with respect to x ( input value ) remains constant for a function then it is called linear function.

Here, number of hours represents input value and minutes represents the output value,

Now, By the given table,

The function is passing through the points (1,60), (2,120), (3,180), (4,240) and (5,300),

Also,

⇒  The rate of change output value with respect to input value remains constant,

Hence, It represents a linear function because there is a constant rate of change.

Can anyone show me the steps in order solve this problem
STatiana [176]
M∠A = 42°   [isosceles triangle]

m∠B = 180 - 42 - 42 = 96°  [in a triangle, the three interior angles always add to 180°]

m∠C = 180 - 96 - (x+12)
m∠C = 84 - x - 12
m∠C = 72 - x

2x+9 + 3x-1 + 72-x = 180
4x + 80 = 180
4x = 180 - 80
4x = 100
x = 100/4
x = 25

m∠C = 72 - x = 72 - 25 = 47°
