Answer:

The surface area of this cylinder. is 266π cm²

Step-by-step explanation:

Surface Area of Cylinder (SA) = 2πrh+2πr²

since r = 7cm & h = 12 cm

Then SA = 2 π (7)(12) + 2π(7²)

SA = 168π + 98π

∴ SA = 266π cm²

Consider the given function and the given interval. f$x$ = (x - 7)**2 text(, ) [5 text(, ) 11] (a) Find the average value fave

Jet001 [13]

a. $f$ has an average value on [5, 11] of

$f_{\rm ave}=\displaystyle\frac1{11-5}\int_5^{11}(x-7)^2\,\mathrm dx=\frac{(x-7)^3}{18}\bigg|_5^{11}=\frac{4^3-(-2)^3}{18}=4$

b. The mean value theorem guarantees the existence of $c\in(5,11)$ such that $f(c)=f_{\rm ave}$ . This happens for

$(c-7)^2=4\implies c-7=\pm2\implies c=9\text{ or }c=5$

3 (x-5) =5 what is x?

azamat

Answer: 20/3

So when solving this equation first distribute our 3,we will now have 3x-15=5.

Next we will Add 15 to both sides of our equation. Now we have 3x=20.Then divide our terms,and you will have 3x/3 = 20/3

This will leave you with 1x=20/3.

So the X is 20/3.

Hope that helped!
