What is the range of y= sec-'(x)? PreCal, send help please!!
beks73 [17]

Given:

The function is:

y=\sec^{-1}(x)

To find:

The range of the given function.

Solution:

We have,

y=\sec^{-1}(x)

The range of secant inverse function is:

Range=\{y|0\leq y\leq \pi , y\neq \dfrac{\pi}{2}\}

The range of the given function in interval notation is:

Range=\left[0,\dfrac{\pi}{2}\right)\text{ and }\left( \dfrac{\pi}{2}, \pi\right ]

Therefore, the correct option is C.

A square of area 36 cm2 is cut out to make two rectangles , A and B The area of area A to area B is 2 : 1 work out the dimension
KIM [24]

Answer:

Dimensions of:

Rectangle A are 6 cm by 4 cm.

Rectangles B are 6 cm by 2 cm.

Step-by-step explanation:

It is given that:

The area of square is 36 cm^2.

Hence, the side of the square is given as:

Area=(side)^2\\\\36=(side)^2\\\\side=6

Hence, the side of square is 6 cm.

Now, as the area of two rectangles A and B are in the ratio:

2:1

This means that, the area of rectangle A is 24 cm^2.

and area of rectangle B is 12 cm^2.

( Since, 36/(2+1)=36/3=12

Area of rectangle A=2×12=24 cm^2.

Area of rectangle B=1×12=12 cm^2. )

Hence, the dimensions of A are:

6 cm by 4 cm.

and the dimensions of rectangle B are:

6 cm by 2 cm.
