Answer:
The answer is (d) ⇒ eccentricity = 6 , hyperbola , directrix x = 3/2
Step-by-step explanation:
∵ r = ek/(1 ± ecosФ)
∵ r = 9/(1 + 6cosФ)
∴ e = 6 ⇒ eccentricity = 6
∵ e > 1
∴ The conic is hyperbola
∵ ek = 9
∴ k = 9/6 = 3/2
∴ The directrix x = 3/2
Answer:
5
Step-by-step explanation:
u do 2x2 cuz of the square root and add the 1
Answer: Hope this helps
Step-by-step explanation: Listen, exponents may be complicated at first but
The basic concept is to think of it like 2 to the 3rd power would be 2x2x2
since you are multiplying the number by itself three times
Answer:
it is the 3rd one
Step-by-step explanation:
Answer:
1. 425,328 -> 425,330
2. 105,025 -> 105,030
3. 45,527 -> 45,530
4. 35,478 -> 35,480
5. 212,369 -> 212,370
Step-by-step explanation:
000,0<u>0</u>0 the underlined number is the tens place. In order for the tens place to round up the ones place must be 5 or above. If the ones place is lower than 5 you round down to the nearest tens.
In Example:
333,389 you would round up to 333,390 because of the 9 in the ones place.
Now, 333,333 you would round down to 333,330 because of the 3 in the ones place
