If the vertex is at the maximum point they dy/dx=0 at that point...
dA/dx=-2x+4
dB/dx=-2x+8
dC/dx=2x-4
dD/dx=2x-8
So both B and D have a zero velocity at x=4, but only B is equal to 3 when x=4
B. is the correct quadratic with the vertex at (4,3)
You can check your work by using a calculator or using another method to find the same answer to the same question. You could also ask a friend
Pleaze mark brainliest!!
<span>In question 3, You don't know the cost of an orchid, so that is r. You have 11 orchids per vase, so that is a cost of 11r per vase. A vase costs $4. 11r + 4 would be the total cost. So, the last choice would be your answer which is:
C = 11r + 4
I hope my answer has come to your help. God bless and have a nice day ahead!

Answer:
<em>49 cm²</em>
Step-by-step explanation:
Answer:
1 - sin² θ = 1 - ( 1 - cos² θ) = cos² θ
tan x csc x = (sin x / cos x) * 1 / sin x = cos x
Step-by-step explanation:
1 - sin² θ = 1 - ( 1 - cos² θ) = cos² θ
tan x csc x = (sin x / cos x) * 1 / sin x = cos x
