Answer:

√a = 3.77

Step-by-step explanation:

2/(√6+√2) * 0.4663 + 4 * 0.4226

= [2(√6+√2)/(√6)²-(√2)²] * 0.4663 + 4 * 0.4226

= (√6+√2)/2 * 0.4663 + 1.6904

= (2.4494 + 1.4142)/2 * 0.4663 + 1.6904

= 1.9318 * 0.4663 + 1.6904

= 0.90079834 + 1.6904

= 2.59119834

Again, √a + √2 = 2.59119834 * 2 = 5.18239668

=> √a = 5.18239668 - 1.41421356 = 3.76818312 ≈ 3.77

Sharon reads two different articles about avocados. The first article, in a weight-loss magazine, claims that avocados are unhealthy because they are high in fat. The second article, in an annual publication from a doctors’ group, claims that the fat in avocados is a type that is good for the heart. To assess these claims, which question might Sharon ask?
Answer:-

{2x|x belongs to N, x<5}

put x<5

x=1, 2,3,4

put x=1, 2(1) =2

put x=2, 2(2) =4

put x=3, 2(3) =6

put x=4, 2(4) =8

Therefore answer={1, 2,3,4}
