$\bf f(x)=|x|+4\implies f(x)=\sqrt{x^2}+4\implies f(x)=(x^2)^{\frac{1}{2}}+4
\\\\\\
\cfrac{dy}{dx}=\stackrel{chain~rule}{\cfrac{1}{\underline{2}}(x^2)^{-\frac{1}{2}}\cdot \underline{2} x}\implies \cfrac{dy}{dx}=\cfrac{x}{(x^2)^{\frac{1}{2}}}

Find the area of the shaded region in the simplest form

balandron [24]

Answer:

A = 24t² + 2t

Step-by-step explanation:

The shaded area (A) is calculated as

A = area of outer square - area of rectangle

= (5t)² - t(t - 2)

= 25t² - t² + 2t

= 24t² + 2t

Tuition for one year at the community college Sean would like to attend is about $8,880. Sean plans to save money each month for

blagie [28]

Answer:

Step-by-step explanation:

he needs 8880. and his parents contribute 6000. so we subtract 6000 from the price of the tuition, bc his parents are paying for 6000 of the 8880 and we get 2880. there are 12 months in a year and he saves up every month for two years, so we multiply 12 by 2 to get 24. then we divide 2880 by 24 and you get 120. i hope this helps
