This is geometric. The next term is 16. Ax+b. A is the initial value, b is the constant and x would be ur values to plug in to get those numbers

Find dy/dx if y =x^3+5x+2/x²-1

stiks02 [169]

<u>Differentiate using the Quotient Rule</u> –

$\qquad$ $\pink{\twoheadrightarrow \sf \dfrac{d}{dx} \bigg[\dfrac{f(x)}{g(x)} \bigg]= \dfrac{ g(x)\:\dfrac{d}{dx}\bigg[f(x)\bigg] -f(x)\dfrac{d}{dx}\:\bigg[g(x)\bigg]}{g(x)^2}}\\$

According to the given question, we have –

f(x) = x^3+5x+2
g(x) = x^2-1

Let's solve it!

$\qquad$ $\green{\twoheadrightarrow \bf \dfrac{d}{dx}\bigg[ \dfrac{x^3+5x+2 }{x^2-1}\bigg]} \\$

$\qquad$ $\twoheadrightarrow \sf \dfrac{(x^2-1) \dfrac{d}{dx}(x^3+5x+2) - ( x^3+5x+2) \dfrac{d}{dx}(x^2-1)}{(x^2-1)^2 }\\$

$\qquad$ $\twoheadrightarrow \sf \dfrac{(x^2-1)(3x^2+5) - ( x^3+5x+2) 2x}{(x^2-1)^2 }\\$

$\qquad$ $\pink{\sf \because \dfrac{d}{dx} x^n = nx^{n-1} }\\$

$\qquad$ $\twoheadrightarrow \sf \dfrac{3x^4+5x^2-3x^2-5-(2x^4+10x^2+4x)}{(x^2-1)^2 }\\$

$\qquad$ $\twoheadrightarrow \sf \dfrac{3x^4+5x^2-3x^2-5-2x^4-10x^2-4x}{(x^2-1)^2 }\\$

$\qquad$ $\green{\twoheadrightarrow \bf \dfrac{x^4-8x^2-4x-5}{(x^2-1)^2 }}\\$

$\qquad$ $\pink{\therefore \bf{\green{\underline{\underline{\dfrac{d}{dx} \dfrac{x^3+5x+2 }{x^2-1}} = \dfrac{x^4-8x^2-4x-5}{(x^2-1)^2 }}}}}\\\\$

Find the volume length 10 2/5 cm, width 3 cm, height 8 1/3 cm

AURORKA [14]

Answer:

260 cm

Step-by-step explanation:

formula for finding volume:

l=length w=width h=height v=volume

$10\frac{2}{5}$ × 3 × $8\frac{1}{3}$

$10\frac{2}{5}$ = $\frac{52}{5}$

how did i do that?

cross multiply the whole number and the denominator together and add the product by the numerator.

$8\frac{1}{3}$ = $\frac{25}{3}$

so, $\frac{52}{5}$ × $\frac{25}{3}$ × $\frac{3}{1}$

cross simplify(dont have to do it just makes everything easier)

and you get:

$\frac{52}{1}$ × $\frac{5}{1}$ × $\frac{1}{1}$

and you get $\frac{260}{1}$

$\frac{260}{1}$ = 260 cm
