Answer:
The circle's diameter is 6cm
Step-by-step explanation:
A = 28.26 cm^2
D = ![\sqrt[2]{\frac{A}{\pi } }](https://tex.z-dn.net/?f=%5Csqrt%5B2%5D%7B%5Cfrac%7BA%7D%7B%5Cpi%20%7D%20%7D)
D = ![\sqrt[2]{\frac{28.26}{\pi } }](https://tex.z-dn.net/?f=%5Csqrt%5B2%5D%7B%5Cfrac%7B28.26%7D%7B%5Cpi%20%7D%20%7D)
D = 6cm
Answer:
Final price = $2034
Step-by-step explanation:
Given the following data;
Marked price = $2000
Tax = 13%
Discount = 10%
To find the final sales price;
First of all, we would calculate the discount price
Discount price = 10/100 * 2000
Discount price = 20 * 10 = $200
New Price = marked price - discount price
New Price = 2000 - 200 = 1800
Next, we calculate the tax on the product;
Tax = 13/100 * 1800
Tax = 0.13 * 1800
Tax = $234
Finally, we would determine the final price;
Final price = marked price + Tax
Final price = 1800 + 234
Final price = $2034

A function, such is a mathematical collection of algebraic terms. Functions can be reflected across the x-axis by multiplying the entire function by -1. In this case multiplying the function by -1 leads to -4x/2. Hence the new function is -4x/2. Functions can also be reflected in the y-axis by replacing x with -x.
