Answer:

a. 8,953.5 seconds

b. 14,400 seconds (check note)

Step-by-step explanation:

y=-4x

y=-35814 (negative because this is underwater)

-35814=-4x

8953.5

The model suggests it would take 8,953.5 seconds for DeepSea Challenger to reach the bottom (2.487083333 hours, or about 2 hours and 30 minutes).

y=4x

x=3600 (positive because the vessel is rising)

4(3600)

14400

It took 14,400 seconds for the DeepSea Challenger to ascend to the surface.

[also note: I'm not sure if the second question is asking for how many seconds it takes to ascend to the surface with reference to the 4 seconds in the previous question (which is how I answered part b) or if it's asking how many seconds 1 hour is, and in that case. the answer is 3,600 seconds. I hope this helps and sorry if it's unclear!]

3. Suppose that MAP and MAC are linear pairs, m ZMAP = 7x - 13 and

Artyom0805 [142]

Answer:

Part A: The line PC and the ray AM formed ∠MAP and ∠MAC

Part B: m∠MAP = 113°

Part C: m∠MAC = 67°

Step-by-step explanation:

* Lets explain what is the linear pairs

- A linear pair of angles is formed when two lines intersect.

- Two angles are said to be linear if they are adjacent angles formed by

two intersecting lines.

- The measure of a straight angle is 180°, so a linear pair of angles

must add up to 180°

* Lets solve the problem

- ∠MAP and ∠MAC are linear pairs

- m∠MAP = 7x - 13

- m∠MAC = 3x + 13

# Part A:

∵ The rays of ∠MAP are AM and AP

∵ The rays of ∠MAC are AM and AC

∴ The common Vertex is A and the common ray is AM

∴ The line is PC and the ray is AM

* The line PC and the ray AM formed ∠MAP and ∠MAC

# Part B:

∵ The measure of linear pairs is 180°

∵ ∠MAP and ∠MAC are linear pairs

∴ m∠MAP + m∠MAC = 180°

∵ m∠MAP = 7x - 13

∵ m∠MAC = 3x + 13

- Substitute these values in the equation above

∴ 7x - 13 + 3x + 13 = 180

∴ 10x = 180

- Divide both sides by 10

∴ x = 18

- To find m∠ MAP substitute the value of x in its expression

∵ m∠MAP = 7x - 13

∵ x = 18

∴ m∠MAP = 7(18) - 13 = 126 - 13 = 113

* m∠MAP = 113°

# Part C:

- To find m∠ MAC substitute the value of x in its expression

∵ m∠MAP = 3x + 13

∵ x = 18

∴ m∠MAC = 3(18) + 13 = 54 + 13 = 67

* m∠MAC = 67°

In experiments in which participants manually tracked a complex pattern that consisted of two segments that were random patterns

PilotLPTM [1.2K]

For the given experiments , participants concluded that complexity is more on the random patterns on every trials compare to one segment that was same for every trial.

As given in the question,

Steps for the experiment where participants manually tracked a complex pattern which consists of two segments are as follow:

In first case : One segment consists of random patterns on every trial that is on every new trial there is new random pattern which participant has to follow.

In second case : Another segment consists of same pattern on every new trial.

After conducting experiment reports conclude that repeated segment with the same pattern present more improved result compare to random patterns. As participants were aware of the same segment on each new trial.

Therefore, given experiments of participants proves the complexity is more on the random patterns on every trials compare to one segment same for every trial.
