Answer:

Step-by-step explanation:

Graph it and you would find that (-2,2) is 3 units higher than the line y=-1. So you would reflect it across by starting at (-2,-1) and count downwards, 3 to get (-2,-4).

Answer:

$\frac{\pi}{43082}\text{ radians per second}$

Step-by-step explanation:

Given,

Time taken in one rotation of earth = 23 hours, 56 minutes and 4 seconds.

Since, 1 minute = 60 seconds and 1 hour = 3600 seconds,

⇒ Time taken in one rotation of earth = (23 × 3600 + 56 × 60 + 4) seconds

= 86164 seconds,

Now, the number of radians in one rotation = 2π,

That is, 86164 seconds = 2π radians

$\implies 1\text{ second }=\frac{2\pi}{86164}=\frac{\pi}{43082}\text{ radians}$

Hence, the number of radians in one second is $\frac{\pi}{43082}$

The value of x is 14

<h3>How to solve for x?</h3>

From the question, the lines from the center of the circle to the chords have equal measures of 9 units

This line divides a chord into equal segments, where each segment is 7 units

So, we have:

x = 7 + 7

Evaluate

x = 14

Hence, the value of x is 14
