A3^2+4=1604
a3=40
a2^2+4=40
a2=6
a1^2+4=6
a1=√2
So the first two terms are √2 and 6, answer C
Answer:
20
Step-by-step explanation:
Given
2x² - y ← substitute x = 3 and y = - 2 into the expression
= 2(3)² - (- 2)
= 2(9) + 2
= 18 + 2
= 20
X can not = 0 because if I did your answer would not be a fraction it would be 0
To find volume, we will use the following equation: V=4/3piR^3
The correct answer should be 1436.76
Step-by-step explanation:
1. ΔABC=ΔCDE: a) according to the condition BC=CD and AC=CE; b) m∠(BCA)=m∠(DCE).
2. if ΔABC=ΔCDE, then m∠(BAC)=m∠(DEC) and m∠(ABC)=m∠(CDE).
3. if m∠(BAC)=m∠(DEC), then AB || DE (or if m∠(ABC)=m∠(CDE), then AB || DE).
