Answer:
2
Step-by-step explanation:
The rate of change is just the slope, which is -6/-3 or 2.
Answer:
c
Step-by-step explanation:
To find the maximum point, differentiate:
D' = -8p +160
Set to zero and solve for p:
D' = 0
⇒ -8p +160 = 0
⇒ 8p = 160
⇒ p = 20
Input p = 20 into the original equation to find D:
D = -4(20)² + 160(20) -310 = 1290
Therefore, the price is $20 and the maximum number of drills is 1,290
I think u just connect the dots
Wait what....? No equal signs or inequalities...?
Here a=1, b= -5 and c= -3
so the discrim. is b^2 - 4(a)(c), or (-5)^2 - 4(1)(-3) = 25 + 12 = 37.
Because the discrim. is +, you'll have 2 real, unequal roots.
