Okay, so there's a number rounded to the nearest million, in this case 2 million. So this tells me that the number of visitors is between 1,500,000 and 2,499,999. The reason why 1,499,999 doesn't count is because the hundred thousands digit is not 5 or above, so it doesn't count. It would round down to 1 million, not 2 million. The reason why 2,500,000 doesn't count, is because the hundred thousands digit is 5, so that rounds to 3 million, not 2 million. The greatest number of visitors that visited the aquarium has to be 2,499,999, because that's one digit away from 2.5 million, and the hundred thousands digit is a 4, not 5. The answer is 2,499,999
Tienes que usar la fórmula cuadrática:
(-b +/- √(b^2-4ac))/2a
Primero identificas los valores de a,b y c en kx^2-3x+2=0
K=a, b=-3, c=2
Luego sustituis en la fórmula y te queda:
(3+/-√(9-8k))/2k
Para que las raíces Sena reales se tienen que cumplir que 9-8k>=0
Answer:
108 feet cubed
Step-by-step explanation:
i think its 24 because you do l*w*h so 4 times 6 equals 24, times 4.5 and its 108.
We have to find 2 areas and to subtract A2 from A1:
A1 = ( r² · π · 45° ) / 360° = ( 6² · 3.14 · 45° ) / 360° = 14.13 ft²
A2 = ( 3² · π · 45° ) / 360° = 3.53 ft²
A ( BCIH ) = 14.13 - 3.53 = 10.6 ft² ≈ 11 ft²
Answer: The area of the glass in the region BCIH is 11 ft² ( rounded to the nearest square foot ).
