Answer:

C. 624 cm^2

Step-by-step explanation:

Find area of bottom rectangle:

12*24 = 288

Find area of upper rectangle (excluding the bottom part)

The bottom part is 12 inches long

(40-12) * 12

28*12

336

336+288 = 624

Alla [95]

Answer:

6\sqrt{6}\ un.

Step-by-step explanation:

Consider right triangle ABC with right angle ACB. If m∠ACD = 45°, then

m∠BCD=m∠ACB-m∠ACD=90°-45°=45°.

Since  CD ⊥ AB, then

m∠CDA=m∠CDB=90°.

Thus, triangles ACD and BCD are right triangles with right angles ADC and BDC. In these triangles:

m∠CAD=90°-m∠ACD=90°-45°=45°;

m∠CBD=90°-m∠BCD=90°-45°=45°.

Thus, triangles ACD and BCD are isosceles right triangles with

CD=AD=BD=6\sqrt{3}\ un.

By the Pythagorean theorem,

AC^2=CD^2+AD^2,\\ \\AC^2=(6\sqrt{3})^2+(6\sqrt{3})^2,\\ \\AC^2=216,\\ \\AC=6\sqrt{6}\ un.

If changes are made to a signature while using version 5.x signature files, are they visible in the router running the configura
tatyana61 [14]
I think that the changes will not be visible in the router running the configuration. This is because they are not part of the router configuration. The version 5.x signature is more advantageous it has an additional signature risk rating feature and it supports encrypted signature parameters. <span />

Firlakuza [10]

Answer:

  4.73%

Step-by-step explanation:

  y = 3×2^(t/15) = 3×(2^(1/15))^t = 3×1.0472941^t

In this form, ...

  1 +r = 1.0472941

  r = .0472941 ≈ 4.73%

The daily increase is about 4.73%.
