True. the equation for the rectangle would be 2L+2W=P and you have the length and width so, 2(24)+2(6)=P P= 60inches or 5ft.

Find the derivative of f(x)= (e^ax)*(cos(bx)) using chain rule
Vikentia [17]

If

f(x) = e^{ax}\cos(bx)

then by the product rule,

f'(x) = \left(e^{ax}\right)' \cos(bx) + e^{ax}\left(\cos(bx)\right)'

and by the chain rule,

f'(x) = e^{ax}(ax)'\cos(bx) - e^{ax}\sin(bx)(bx)'

which leaves us with

f'(x) = \boxed{ae^{ax}\cos(bx) - be^{ax}\sin(bx)}

Alternatively, if you exclusively want to use the chain rule, you can carry out logarithmic differentiation:

\ln(f(x)) = \ln(e^{ax}\cos(bx)} = \ln(e^{ax})+\ln(\cos(bx)) = ax + \ln(\cos(bx))

By the chain rule, differentiating both sides with respect to <em>x</em> gives

\dfrac{f'(x)}{f(x)} = a + \dfrac{(\cos(bx))'}{\cos(bx)} \\\\ \dfrac{f'(x)}{f(x)} = a - \dfrac{\sin(bx)(bx)'}{\cos(bx)} \\\\ \dfrac{f'(x)}{f(x)} = a-b\tan(bx)

Solve for <em>f'(x)</em> yields

f'(x) = e^{ax}\cos(bx) \left(a-b\tan(bx)\right) \\\\ f'(x) = e^{ax}\left(a\cos(bx)-b\sin(bx))

just as before.

How to reduce 10/4 i don’t know how to
vredina [299]

answer: 10/4 reduced is 2.5/1 or 2.5.

work: what we are doing is trying to divide ten into groups of four. how many times does 10 fit into four? well, look at the multiples of four, 4, 8, 12... we can see that 8 fits into ten, but 12 doesn't. that means two whole fours can fit into ten (since 4 x 2 = 8) so we still have a  2 left over from the ten. since 2 is one half of four, we can fit in another .5. so, ten can be fit into 2.5 groups. hope this helps, have a great day!
