Answer:
a = -
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k ) = (105, 27 ) , thus
y = a(x - 105)² + 27
To find a substitute (109, 14 ) into the equation
14 = a(109 - 105)² + 27 ( subtract 27 from both sides )
- 13 = 16a ( divide both sides by 16 )
a = -

Answer:
The price at discounted rate = $ 16.8
Step-by-step explanation:
Given in question as ,
The rate of cashews for selling = $14 per pound
Now Carla discounting the price by 20%
So , new price of cashews = 14 - (20% × 14)
Or, = 14 ×
Or, New price of cashews = $11.2 per pound
Again , Carla buys pounds of cashews at discounted price
∵ , cost of 1 pound cashews = $ 11.2
∴ , cost of pound = × $ 11.2
=
= $ 16.8
Hence the price at discounted rate = $ 16.8 Answer
