The dimensions of a room are 4.2m by 6m. On a plan, the longer side is equal to 4 cm. What is the length of the shorter side on

Fiesta28 [93]

Answer: Length of shorter side is 2.8 cm.

Explanation:

Since we have given that

Dimensions of a room are given by

$4.2\ m\times 6\ m$

On a plan, the longer side = 4 cm

As we know that the ratio of original room is equal to ratio of plan room

So,

$\frac{4.2}{6}=\frac{x}{4}\\\\4.2\times 4=6x\\\\16.8=6x\\\\\frac{16.8}{6}=x\\\\2.8=x$

So, length of shorter side is 2.8 cm.

Given that f(x)= x^2-3/2 find f^-1(x)

Scilla [17]

Answer:

$\bold{f(x)=-\frac{1}{2}}$

Step-by-step explanation:

$f(x)= x^2-\frac{3}{2}$ replace x with -1

$f(x)= -1^2-\frac{3}{2}$ solve exponents

-1² = -1 × -1 = 1

$f(x)= 1-\frac{3}{2}$ subtract

$\bold{f(x)=-\frac{1}{2}}$
