Answer:
k = -21
Step-by-step explanation:
9/ (2k-3) = 4/(k+1)
Using cross products
9 * (k+1) = 4(2k-3)
Distribute
9k+9 = 8k -12
Subtract 8k from each side
9k-8k +9 = 8k-8k-12
k+9 = -12
Subtract 9 from each side
k+9-9 = -12-9
k = -21
Answer:

Step-by-step explanation:
Hey There!
The first step of this problem is to find the formula for arc length
r=raduis
0 = angle
now we just plug in the values
so the arc length equals 9.424777961
the last step is to round to the nearest hundreth
so your final answer is 9.42
Answer:
