Hi,

Everything with exponent equal to 0 is 1.

The equation is therefore:

1 + 1 = 2

Hope this helps.

This is for AP CALCULUS. I really need help on this. I’m trying to find the first and second derivative of these three functions
ale4655 [162]

Review Material:

\sqrt[n]{x^m} = x^{\frac{m}{n}}

\frac{d}{dx}[x^n]=nx^{n-1}\\

\frac{d}{dx}[\sin(x)]=\cos(x)\\

 \frac{d}{dx}[\cos(x)]=-\sin(x)\\

\frac{d}{dx}[constant]=0\\

Step-by-step explanation:

(a)

F(x) = -2\cos(x) +x^{\frac{4}{3}} -3e\\ \text{Note: 3e is a constant}\\F'(x) = 2\sin(x) + \frac{4}{3}x^{\frac{1}{3}}\\F''(x) = 2\cos(x) + \frac{4}{9}x^{-\frac{2}{3}}

(b)

F(x) = x^{-3} + \frac{1}{2}x^2-\sin(x)\\F'(x)=-3x^{-4} + x - \cos(x)\\F''(x) = 12x^{-5} + 1 + \sin(x)

(c)

F(x) = 2x^{-3}+x^{\frac{3}{4}}-4x\\F'(x) = -6x^{-4} + \frac{3}{4}x^{-\frac{1}{4}}-4\\F''(x)= 24x^{-5} - \frac{3}{16}x^{-\frac{5}{4}}

PLEASE SOLVE
kherson [118]

Answer:

14/5

Step-by-step explanation:

So first i manipulated a/b= 2/5. i multiplied both sides by 5 making it 5a/b=2. Then i multiplied both sides by b making it 5a=2b. Then i substituted 2b into 5a+3b=35. Making it 2b+3b=35. then i simplified it making it 5b=35. Then i solved for b making it b=7. Then i substituted b into 5a+3b=35. So that it looked like this 5a+3*7=35. then it became 5a+21=35. Then you subtract 21 making it 5a=14. You then divide by 5 making it a=14/5
