DochEvi [55]

Answer:

700 miles

Step-by-step explanation:

Given:

Scale of the map is $\frac{1}{2}\textrm{ in}=50\textrm{ mi}$

∴ $1\textrm{ in}= \frac{50}{\frac{1}{2}}=50\times 2=100\textrm{ mi}$

Distance of Susan from mount Shasha on the map is 7 inch.

Therefore, Number of miles = $7\times 100=700\textrm{ mi}$

Hence, Susan must travel 700 miles to reach her destination.

Find a formula for the described function. An open rectangular box with volume 3 m3 has a square base. Express the surface area

Alex73 [517]

Answer:

$SA(x) = x^2 + \frac{12}{x}$

Step-by-step explanation:

Given

$V = 3m^3$ --- volume

$x \to base\ length$

$y \to height$

Required

The surface area as a function of base length

The volume (V) is calculated as:

$V = Base\ Area * Height$

$V = x*x*y$

$V = x^2*y$

Make y the subject

$y = \frac{V}{x^2}$

Substitute 3 for V

$y = \frac{3}{x^2}$

The surface area of the open box is:

$SA = x^2 + 2xy+2xy$

$SA = x^2 + 4xy$

Substitute: $y = \frac{3}{x^2}$

$SA = x^2 + 4x*\frac{3}{x^2}$

$SA = x^2 + 4*\frac{3}{x}$

$SA = x^2 + \frac{12}{x}$

Hence, the function is:

$SA(x) = x^2 + \frac{12}{x}$
