The scale factor of the dilation is 1 over 2. Why? Well, going from A to A prime is a reduction of 1/2, going from B to B prime is a reduction of 1/2, and going from C to C prime is a reduction of 1/2. The figure is dilated, meaning it is shrunk rather than the shape and orientation being changed.

Delia has 3 5/8 yards of ribbon. About how many 1/4 yard-long pieces can she cut?
grin007 [14]

Answer: There are 14 long pieces she can cut.

Step-by-step explanation:

Since we have given that

Length of yards of ribbon is given by

3\frac{5}{8}\ yards\\\\=\frac{29}{8}\ yards

Length of yards of ribbon pieces need to be cut is given by

\frac{1}{4}\ yards

Number of yards is given by

\frac{\frac{29}{8}}{\frac{1}{8}}\\\\=\frac{29}{2}\\\\=14.5\\\\=14

Hence, there are 14 long pieces she can cut.

Find the domain of the function algebraically:<br><br> <img src="https://tex.z-dn.net/?f=R%28x%29%3D%5Cfrac%7Bx%7D%7Bx%5E%7B2%7D
BigorU [14]

The domain of the function is all real numbers except 2 and -1

Step-by-step explanation:

Domain is the set of inputs of a function on which the function is defined.

Given function is:

R(x) = \frac{x}{x^2-x-2}

In case of a function involving fraction, the function is undefined if the denominator is zero so in order to find the domain of the function algebraically , we have to find the values on which the function will be undefined

x^2-x-2 = 0\\x^2-2x+x-2 = 0\\x(x-2)+1(x-2) = 0\\(x+1)(x-2) = 0\\x+1 = 0 => x=-1\\x-2=0 = > x=2

The function will be undefined on x=-1 and x=2

So,

The domain of the function is all real numbers except 2 and -1
