Answer:
B. Identity
Step-by-step explanation:
Answer:
factor left the side of the equation
(2k_9)(k+2)=0
set factors equal to 0
2k_9=0 or k+2=0
the answer is K= 9/2 or K =-2
Based on the information given, it can be deduced that the initial cost will be $187 and the hourly rate is $72 per hour.
From the information given, the initial cost is $187. The cost for 2 hours is $259 and the cost for 3 hours is $331.
Therefore, the rate per hour will be:
= $259 - $187 = $72
The equation will then be:
= 187 + 72h
Lastly, the difference in the costs is $72.

It is given in the question that the end of a pendulum with a length of 21 cm travels an arc length of 24 cm.
So here radius is 21 cm and the arc length is 24 cm .
Now we use the arc length formula , which is
Where s is the arc length and r is the radius.
Substituting these values, we will get
And now we need to convert radian to degree, and for that we have to multiply by 
That is
