Answer:
Step-by-step explanation:
(x⁴+ax²+b) ÷ (x+1) = x³-x²+(a+1)x-(a+1) remainder b+(a+1)
Since x+1 is a factor, b+(a+1) = 0.
(x³-x²+(a+1)x-(a+1)) ÷ (x+2) = x²-3x+(a+7) remainder -3a-15
Since x+2 is a factor, -3a-15 = 0
a = -5
b = 4
x⁴+ax²+b = x⁴ - 5x² + 4 = (x²-4)(x²-1) = (x+2)(x-2)(x+1)(x-1)
Answer:
13,100 mi²
Step-by-step explanation:
If 80% of the area of WI is land area, then that area is 0.80(35,498 mi²).
If (100% - 80%), or 20%, is not land area, then that area comes to
0.20(65,498 mi²), or 13,100 mi² (rounded up from 13,099.6).
Probability that gear 1 will fail = 5/100 (upto 10 years)
and 8/100 (after 10 years)
Probability that both will fail = 5/100 * 8/100
= 40/10000
= 0.4 %
It would all depend on the number and the factors they have.
For example:
A. What is the LCM of 4 and 8? As you can see, 8 is a multiple of 4 since 4×2=8
But 4 is NOT a multiple of 8 so that means 8 is the LCM.
B. What is the LCM of 3 and 6? As you can see, 6 is a multiple of both 3 and 6 but 3 is not a multiple of 6
Answer: So based off on what I showed you, the LCM of two numbers where one is the multiple of the other number is the multiple of the other number. In other words, the bigger of the two numbers
It would be C since it is a non terminating decimal that has a pattern. Example: 2.34456432234......
