A) 27, 85
B) 70, 60, 30
C) B=43,750, G=42,940, A=18,130
Answer:
The answer is "3".
Step-by-step explanation:
differentiate the function f(x):
Formula:
since the value of x in: and . So, the value of a is 3
Answer:
(x - 3) is a factor of P(x)
Step-by-step explanation:
if (x - 3) is a factor of P(x) then P(3) = 0
P(3) = 2(3)³ + 5(3)² - 28(3) - 15
= 2(27) + 5(9) - 84 - 15
= 54 + 45 - 99
= 99 - 99
= 0
since P(3) = 0 then (x - 3) is a factor of P(x)
