Proving that EFGH is a square: points E,F,G,H
separate the sides of the square ABCD into two lines. if AE=BF=CG=DH then
AH=DG=EB=FC and it shows that if we connect the points E,F,G,H to each other with line we will have a square

HAE~EBF~FCG~GDH by rule SAS

If L ll M, classify the marked angle pair and give their relationship, then solve for x
Talja [164]

Answer:

Supplementary angle; x = 14.

Step-by-step explanation:

Angle (9x - 2) and angle (10y + 6) form a straight line, so they form a supplementary angle.

Because angle (9x - 2) and (5x + 54) are corresponding angles, we can set them equal to each other.

9x - 2 = 5x + 54

9x - 5x = 54 + 2

4x = 56

x = 14.

Hope this helps!

Krypton-91 is a radioactive substance that decays very quickly. The function Q(t)=Qoe^-kt models radioactive decay of krypton-91
Masteriza [31]
The "k" value should have units and should be negative.
k = -.07 / seconds
Half-Life = ln (.5) / k
Half-Life = ln (.5) / -.07
Half-Life = -.693147 / -.07
Half-Life = 9.9 seconds
(actually, wkpedia says half-life of Krypton 91 is 8.57 seconds)

elapsed time = half-life * log (bgng amt / end amt) / log (2)
elapsed time = 9.9 * log (100 / 10) / 0.30102999566
elapsed time = 9.9 * 1 / 0.30102999566
<span><span>elapsed time = 9.9 * 3.3219280949 </span>
</span><span><span><span>elapsed time = 32.8870881395 </span> </span> </span>
<span>elapsed time = 32.89 seconds (rounded)
