Answer:
Step-by-step explanation:
Volume = 67*20 = 1340 cubic cm
(x²+9)*(25(x²-4x+4))
x=±√-36/2, so x=±3i
x=4±√(16-16)/2, so x=2 is a double root
depends on how your teacher instructed you to county roots. there are 2 complex solutions and two real solutions because 2 is a double root. that would be D. however there are only 3 DISTINCT roots, , 3i, -3i, and 2 which would be C. The CORRECT answer to a mathematician would be D
Answer: it C
Step-by-step explanation: if it not incorrect sorry for the wrong answer
2000=1800(1.04)^t,,log(1.11)/log(1.04)=t use the calculator,,,hope it helps :-)
I would say 640.5 centimeters. However, remember that this is high school work, and I am only in middle school. This may not be correct, as I am doubting myself, yet cannot find errors in my work. Please take caution with this answer! Hope this isn't a detriment to you, bye! :)
