H = {z∣z ∈ N and 82 ≤ z ≤ 106}<br><br><br> H has ___ subsets.<br> H has ___ proper subsets.
IRINA_888 [86]

Answer:

Step-by-step explanation:

Notice that H is a set with 106 - 81 = 25 elements.

Hence H has 2^{25} subsets.

In order to get the proper subsets of H we just need to deduct one from 2^{25}

So there are 2^{25}-1 proper subsets.

What is the smallest of 3 consecutive positive integers if the product of the smaller two integers is 5 less than 5 times the la
olga55 [171]
Let's say the first number is "a"
the next consecutive can just be "a+1" and  the next, you guessed it, "a+2"
the two smaller ones are a and a+1, the larger one is a+2

now, the product of "a" and "a+1" equals 5 times "a+2" but less by 5

thus   a(a + 1) = 5(a + 2) - 5   <----- solve for "a"
