X intercept would mean plug in 0 for Y.
Then finding the y intercept would mean X is 0. Your answer will be 69420

Answer:

1308

Step-by-step explanation:

PEMDAS has us do 6^4 first which is 1296. Then we can do 6*2 which is 12 then 12 + 1296 is 1308.

1/2 = 1/a + b/c make b the subject

SCORPION-xisa [38]

Answer:

b = $\frac{ac-2c}{2a}$

Step-by-step explanation:

Given

$\frac{1}{2}$ = $\frac{1}{a}$ + $\frac{b}{c}$

Multiply through by 2ac to clear the fractions

ac = 2c + 2ab ( subtract 2c from both sides )

ac- 2c = 2ab ( divide both sides by 2a )

$\frac{ac-2c}{2a}$ = b

7-18 use part 1 of the fundamental theorem of calculus to find the derivative of the function.

blondinia [14]

$\displaystyle h(x)=\int\limits_{1}^{\sqrt{x}}~\cfrac{z^2}{z^4+1}dz~\hspace{10em}\cfrac{dh}{du}\cdot \stackrel{chain~rule}{\cfrac{du}{dx}\implies \cfrac{dh}{dx}} \\\\[-0.35em] ~\dotfill\\\\ u=\sqrt{x}\implies \cfrac{du}{dx}=\cfrac{1}{2\sqrt{x}} \\\\[-0.35em] ~\dotfill$

$\cfrac{dh}{dx}\implies \displaystyle \cfrac{d}{du}\left[ \int\limits_{1}^{u}~\cfrac{z^2}{z^4+1}dz \right]\cdot \cfrac{1}{2\sqrt{x}}\implies \left[ \cfrac{u^2}{u^4+1} \right]\cdot \cfrac{1}{2\sqrt{x}} \\\\\\ \stackrel{substituting~back}{\left[ \cfrac{(\sqrt{x})^2}{(\sqrt{x})^4+1} \right]\cdot \cfrac{1}{2\sqrt{x}}}\implies \cfrac{x}{x^2+1}\cdot \cfrac{1}{2\sqrt{x}}\implies \cfrac{\sqrt{x}}{2x^2+2}$
