Answer:

y > x² - 6

y < x² + 2                               Option A

Step-by-step explanation:

Given that,

Two parabolic inequality's graph is given.

If we graph inequality y > x² - 6

it shaded the upper part of graph because greater than sign is given.

If we graph inequality y < x² + 2

it shaded the lower part of graph because less than sign is given.

So, common shaded part is mid of both the graph.

Final answer is:

y > x² - 6

y < x² + 2

That's the final answer.

What is the measure of each angle of a regular 24-gon? If necessary, round to the<br> nearest tenth.
Butoxors [25]

Answer:

165°

Step-by-step explanation:

Find the interior angle measure by using the formula, ((n - 2) x 180°) / n

Plug in 24 as n:

((n - 2) x 180°) / n

((24 - 2) x 180°) / 24

(22 x 180°) / 24

3960 / 24

= 165

So, the measure of each angle is 165°

A train travels 110 km in the same time that a plane covers 385 km. If the speed of the plane is 20 km per hr less than 4 times
slamgirl [31]

Answer:

  • train: 40 kph
  • plane: 140 kph

Step-by-step explanation:

Let t represent the speed of the train in km/h. Then 4t-20 is the speed of the plane. Travel times are the same, so we can use the formula ...

  time = distance/speed

and equate the travel times.

  110/t = 385/(4t-20)

Cross multiplying gives ...

  110(4t -20) = 385t

  440t -2200 = 385t . . . . . eliminate parentheses

  55t -2200 = 0 . . . . . . . . . subtract 385t

  t -40 = 0 . . . . . . . . . divide by 55

  t = 40 . . . . . . . . . . . add 40; train's speed is 40 kph

  4t -20 = 140 . . . . . . find plane's speed; 140 kph

The train's speed is 40 km/h; the plane's speed is 140 km/h.

_____

<em>Check</em>

Train's travel time = 110 km/(40 km/h) = 2.75 h.

Plane's travel time = 385 km/(140 km/h) = 2.75 h.
