Legit way is vertex form
easy way is this
x value of vertex in form
f(x)=ax^2+bx+c is -b/2a
the y value is f(x value of vertex)
so
p(x)=-0.5x^2+40x-300
x value of vertex is -40/(2*-0.5)=-40/-1=40
max profit selling 40 per week
profit would be 500
30,000 pounds.
I hope this helps! :)
Answer:
384 possible combinations are available.
Step-by-step explanation:
Types of sandwiches = 3
Types of bread = 2
Available toppings = 6
Choices for each topping = 2
Total combinations available = 3.2.2.2.2.2.2.2
= 3(128)
= 384
Yes they are
. 90/150= 3/5
so 45/75 and 3/5.
Answer:
Flip vertical then shift (translation) right 1 unit
Step-by-step explanation:
A (-3,0) B (2,-1) C (-1,2) .... green triangle
Flip vertical becomes
A (-3,1) B (2,2) C (-1,-1) .... blue triangle
shift to right 1 unit
A (-2,1) B (3,2) C (0,-1) .... red triangle
