Answer:
(I can't figure out number one)
2. 7 1/2 feet below sea level or -7 1/2 feet
3. It would stop on the 17th floorl
Step-by-step explanation:
2. You subtract 20 1/2 by 28 to get your answer. Flipped around, 28 - 20 1/2 is 7 1/2 so back to the right way would be -7 1/2 or 7 1/2 feet below sea level.
3. 23 + 5 = 28
28 - 14 = 14
14 + 3 = 17
So the 17th floor would be the answer.
Answer:
Step-by-step explanation:
a) 3x^2-12x-11=3*x^2-3*2*2*x+3*4-23=3*(x^2-2*2x+2^2)-23=3*(x-2)^2-23
so a= -2 ,b= -23
b) x1=[12+V(12^2-4*3* -11)]/6=12/6+V(144+132)/6=2+2/6V69=2+1/3V69=
2+V69/9=2+V23/3
c=2, d= 23/3
Cosine = adjacent / hypotenuse
cosine = 5 / 13
answer is a)
Im pretty sure its obtuse
