Oi

Just calculating the differential. Step by step:

$y=12 \sqrt{x} -x \frac{3}{2}-10 \\ \\ y=12x^{ \frac{1}{2} } -x \frac{3}{2}-10 \ \ \ \boxed{transform \ \sqrt{x} =x^{ \frac{1}{2} }} \\ \\ Differentiating \\ \\ y'=12. \frac{1}{2}.x^{ \frac{1}{2}-1 } -1.x^{1-1}. \frac{3}{2}-0 \\ \\ y'=6.x^{ -\frac{1}{2} } -x^{0}. \frac{3}{2} \\ \\ y'=6. \frac{1}{x^{ \frac{1}{2} }} -1. \frac{3}{2} \\ \\ \boxed{y'=\frac{6}{ \sqrt{x} } -\frac{3}{2}}$

If you want to know where the tangent has no slope:

$\frac{6}{ \sqrt{x} } - \frac{3}{2} =0 \\ \\ \frac{6}{ \sqrt{x} } = \frac{3}{2} \\ \\ 3 \sqrt{x} =12 \\ \\ \sqrt{x} = \frac{12}{3} \\ \\ \sqrt{x} =4 \\ \\ (\sqrt{x})^2 =4^2 \\ \\ x=16$

If a perimeter of a room is 78 feet, what is the area of the floor of the room?

Andrei [34K]

The perimeter doesn't tell you the area, and neither of them
can be calculated by knowing the other one.

Check this out:

Dimensions   Perimeter   Area .

1 by 38 78 38 square feet
2 by 37 78 74 square feet
3 by 36 78    108 square feet
5 by 34 78    170 square feet
10 by 29      78       290 square feet
15 by 24      78    360 square feet
17 by 22      78    374 square feet
19 by 20      78    380 square feet
19.5 by 19.5    78    380.25 square feet

Nine same perimeters, nine different areas !

Here's one more ... a long skinny one:

1 inch by 38ft 11in    Perimeter = 78 ft. Area = 3.24 square feet.
