Answer:
Vertex form:
The vertex is
Step-by-step explanation:
For a general quadratic function the form is:
For the function
The values of the coefficients for the function are the following: , ,
Take the value of b and divide it by 2. Then, the result obtained squares it.
Add and subtract
Write the expression of the form
The vertex is

A rotation 270° counterclockwise about the origin is the same as rotation 90° clockwise about the origin and has a rule:
(x,y)→(y,-x).
Then:
- D(−2,4)→D'(4,2)
- E(4,7)→E'(7,-4)
- F(10,3)→F'(3,-10)
- G(8,0)→G'(0,-8)
Answer: the coordinates of vertices of quadrilateral D′E′F′G′ are D'(4,2), E'(7,-4), F'(3,-10), G'(0,-8).
The Markup percentage is mathematically given as
M=42%
<h3>What is Mark up percentage?</h3>
The markup % may be determined by dividing the gross profit of a unit (the difference between its sales price and the amount it cost to create or buy for resale) by the amount that unit originally cost. If a product sells for $12 but only costs the corporation $8 to produce it, the markup percentage for that product is 50%, which can be calculated as (12 - 8) divided by 8.
Generally, the equation for is Total cost price mathematically given as
TCP= Pay+insurance
Therefore
TCP=35.5*1.6
TCP=284/5
Generally, the equation for is Total selling price mathematically given as
TSP=89.99+7.99
TSP=97.98
In conclusion, Mark up percentage is
M=0.4202898551*100
M=42%
