HELP ME PLEASE…….Which table represents a function that does not have a constant rate of change ?
1 answer:
<h3>Answer: Choice B</h3>
Explanation:
Notice that the jump from y = 9 to y = 10 is +1
But the jump from y = 10 to y = 12 is +2
This is sufficient info to say that the rate of change is <u>not</u> constant. The change in y must be the same.
If you were to plot these points on the same xy grid, then you could see that it's impossible to draw a straight line through all four points.
See below.

<em><u>Question:</u></em>
In a circle with a radius of 12.6 ft, an arc is intercepted by a central angle of 2π/7 radians.
What is the arc length?
Use 3.14 for π and round your final answer to the nearest hundredth.
Enter your answer as a decimal in the box.
<em><u>Answer:</u></em>
<h3>Arc length is 11.30 feet</h3><em><u>Solution:</u></em>
Given that,
Radius of circle = 12.6 feet
Central angle = radians
To find: Arc length
<em><u>The arc length of a circle of radius "r" when central angle given in radians is:</u></em>
Where,
s is the arc length
r is the radius
is the central angle in radians
<em><u>Substituting the values we get,</u></em>
Thus, arc length is 11.30 feet
