Find the length L of the curve
1 answer:
Answer:
4.647 to the nearest thousandth.
Step-by-step explanation:
The formula for the length of an arc between x = a and x = b is
a
∫ √( 1 + (f'(x))^2) dx
b
Here f(x) = √x so
we have ∫ (√( 1 + (1/2 x^-1/2))^2 ) between x = 0 and x = 4.
= ∫ ( √( 1 + 1/(4x)) dx between x = 0 and x = 4.
This is not easy to integrate but some software I have gives me the following
length = √17 + 1/8 log(33 + 1/8 √17)
= 4.647.

Use the Pythagorean theorem for this. (a^2+b^2=c^2)
a=9, b=12, c=x
9^2+12^2=c^2
81 + 144 = c^2
225 = c^2
c =15
the answer is c
It’s d because u need to know how to divide
Q20) c < 82-76
c < 6
