You need 3 points to graph a quadratic function.
It is advisable that one of these points be the vertex, because the line of symmetry passes through it
Next, you need to find two other points that lie on the curve, replacing an x-value into the function and calculating the y-value. It is easier if these two points are at the same distance from the line of symmetry.
For example, if the quadratic function is y = (x - 4)² + 3, the vertex is located at (4, 3). Replacing with x = 3 into the equation, we get:
y = (3 - 4)² + 3
y = 1 + 3
y = 4
Replacing with x = 5 into the equation, we get:
y = (5 - 4)² + 3
y = 1 + 3
y = 4
Now, we need to connect the points (3, 4), (4, 3), and (5, 4) with a U shape, as follows:
2( coin faces) 8( number of times)
18 ? am not really sure tho its kinda difficult lol
Answer:
The clearance price is $17.28.
The clearance price will not give the store any profit.
Step-by-step explanation:
We have been given that a store pays a manufacturer $20 for a hat. To make a profit, the store prices the hat 60% higher than the amount they paid.
The price of the hat after increasing the price by 60% will be:
So, the price of hat after the increase of 60% will be $32.
As the sale reduces the price of hat by 10%, so the price of hat after sale will be:
So the price of hat after 10% sale will be $28.8.
As the clearance sale reduces the price by 40%, so price of hat after clearance sale will be 28.8 minus 40% of 28.8.
Therefore, the clearance price is $17.28.
As store has purchased the hat from manufacturer for $20 and sold it $17.28, therefore, the store will not have a profit.
