Rasek [7]2 years ago

Step-by-step explanation:

5^2=5×5

10^3=10×10×10

(25×25×t^8)/(100×t^4)

(625×t^8)/(100t^4)

exponents of the same variable subtract when they are divided

the 8 and 4 are subtracted so,

(625/100)×(t^4)

6.25t^4

Answer:

0.625t^{4}

Step-by-step explanation:

  =\frac{(25)(5)^{2} t^{8} }{(10)^{3} t^{4} }=\frac{625t^{8} }{1000t^{4} }  =0.625t^{8-4} =0.625t^{4}

Hope this helps

4 gallons = 6 miles
Multiply by 4.
16 gallons = 24 miles

Implicit differentiation of 1/x +1/y=5 y(4)= 4/19<br> y'(4)=?
Aneli [31]
\frac{1}{x} +\frac{1}{y} = 5\\\\x^{-1}+y^{-1}=5\\

Above, I changed the fraction form of x and y into exponential form so it is easier to see the differentiation. Now, we can differentiate:

-1x^{-2}+-1y^{-2}\frac{dy}{dx}=5\\\\\frac{-1}{x^2}-\frac{1}{y^2}\frac{dy}{dx}=5\\\\-\frac{1}{y^2}\frac{dy}{dx}=5+\frac{1}{x^2}\\\\\frac{dy}{dx}=-5y^2-\frac{y^2}{x^2}

Now that we have dy/dx, we can plug in the x, which is 4, and the y, which is 4/19. We know these values of x and y because your question stated y(4) = 4/19.

\frac{dy}{dx}=-5(\frac{4}{19})^2-\frac{(\frac{4}{19})^2}{(4)^2}\\\\\frac{dy}{dx}=-5(\frac{16}{361})-\frac{(\frac{16}{361})}{16}\\\\\frac{dy}{dx}=\frac{-80}{361}-\frac{1}{361}\\\\\frac{dy}{dx}=\frac{-81}{361}
