The price of the box of 15 stickers is $6. The price of the box of 25 stickers is $8. All prices are without tax, and the price

REY [17]

Answer:

$y=0.2x+3$

Step-by-step explanation:

Let

x ----> the number of stickers

y ----> the price of the boxes

we have the points

$A(15,6),B(25,8)$

<em>Find the slope</em>

$m=(8-6)/(25-15)$

$m=2/10=0.20$

<em>Find the equation of the line into point slope form</em>

The equation is equal to

$y-y1=m(x-x1)$

substitute the value of m and the point A

$y-6=0.2(x-15)$

$y=0.2x-3+6$

$y=0.2x+3$ ----> linear equation that represent the situation

A runner is running a 10 km race. it takes her 17.5 minutes to reach the 2.5 km mark. at that rate, how long will it take her to

cluponka [151]

First find the unit rate. Do 17.5/2.5 and you get 7. Next just multiply that by 10 and voila. It takes her 70 minutes to run the whole race.

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

blondinia [14]

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

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