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.

Given that QT is an altitude of triangle QRS, measure of angle QTS=(6x+36), and QR = 2x – 5, find QR.

Alexeev081 [22]

We know that
if <span>QT is an altitude of triangle QRS
then
</span><span>the measure of angle QTS is equal to 90</span>°
so
6x+36=90-----> 6x=90-36----> x=54/6
x=9
QR=2x-5-----> QR=2*9-5-----> QR=18-5-----> QR=13

the answer is
QR=13
