I believe the expression would be 7(g)+7
F(x) = cos x
f'(x) = -sin x
f''(x) = -cos x
f'''(x) = sin x
f''''(x) = cos x
90/4 = 22 Remainder 2
Therefore, 90th derivative of f(x) = cos x is -cos x.
Hey there
Solution
1) <span>Divide each side by</span> 2
<span>v > </span>

2) Simplify

to 5
<span>v>5
Answer -- </span>v><span>5</span>
X^2 + (y-8)^2 = 64
use the center for the left side of the equation. X goes with X, Y goes with Y. Always do the opposite sign. The equation is equal to the radius squared
Hope this helped : )
