Answer:
L = 4.103
Step-by-step explanation:
we have length of curve

where 
substituting for f(x), we have 
(since the limit is 2≤ x ≤5)
solving, 
Simplifying this integral, we have
L = 4.10321
Answer: 2.10
Step-by-step explanation: 2.10 * 4 + 6
Answer:
i want to say 36, im not 100% sure though
Step-by-step explanation:
So we see that the ratio between the two octagons is 7:1, since 28/4=7 so what we do next is multiply the values of the smaller octagon by 7. But that’s the long way. There’s actually a shortcut by multiplying the perimeter of the smaller octagon, 34, by 7. This in turn equals 238.
Answer:
-48/15, simplified to -16/5
Step-by-step explanation:
The reciprocal of -3/8 is -8/3. So the equation will be 6/5 x -8/3. Multiply numerators then multiply denominators to get -48/15. This can simplify to -16/5 by dividing both by 3.
