In a market a $50 dress is marked. It says "Save 25%." What is the discount? What is the sale price of the dress?
ehidna [41]

Answer:

$ 37.5

Step-by-step explanation:

It is given :

Price of the dress in the market = $ 50

The shopkeeper a discount percentage = 25%

Therefore the discount amount is = 25 % of 250

                                                         $=\frac{25}{100}\times 50$

                                                         = 12.5

Therefore the sale price of the dress is =  50 - 12.5

                                                                  = 37.5

Therefore the sale price is $ 37.5

Find the domain of the function using interval notation.<br> <img src="https://tex.z-dn.net/?f=f%28x%29%3D8%5Csqrt%7Bx-9%7D" id=
Irina18 [472]

Answer:

D_{f(x)} = [9, \infty)

Step-by-step explanation:

Here we have the square root of a function, in the following format:

f(x) = \sqrt{g(x)}

For the square root, and roots of even numbers(root of 4, 6, ...), we have the following condition in the domain

g(x) \geq 0

In this problem, we have that:

f(x) = 8\sqrt{x-9}

So

x - 9 \geq 0

x \geq 9

So the domain is

D_{f(x)} = [9, \infty)
