Use the equation given below to find f '' (π/ 3) . f(x) = sec x

1 answer:

8 0

F'(x) = secxtanx
f''(x) = (secx)^3 + (secx)^2*(tanx)^2
Plug in $\pi$ / 3 and you get 8 + 12 = 20

Check me on that i did it in my head but it should be right

The speed, v, of a wave is inversely proportional to the square root of the

yKpoI14uk [10]

Answer:

v = 120

Step-by-step explanation:

If v is inversely proportional to square root of d, then we can write

$v \sqrt{d}$ = k

If v = 30 and d = 400, then

30( $\sqrt{400}$ ) = k

k = 30(20) = 600

Now $v \sqrt{d}$ = 600

If d = 25, then v $\sqrt{25}$ = 600

5v = 600

v = 120
