Answer:
circiut analysis
second law of thermodynamics
Step-by-step explanation:
in RC and Ral circiut, first order differential equations is an appropriate approach to solving the circuits
In the figure, tx is perpendicular to line RS.this means we can use the pythagorean theorem to determine RX length the long way or simply apply the theorem that each divided triangle becomes a 30-60-90 angle. If opposite to 60 deg is equal to 6 units, then the side's length is equal to 2*6/sq rt 3 or equal to 6.93 units. The answer is half of this equal to 3.47 units.
<u>Answer:</u>
The height of the model is 2 feet 10.5 inches.
<u>Step-by-step explanation:</u>
<u>Given:</u>
scale of 1/3 inch=2ft
actual tower is 207 feet
<u>To Find:</u>
The height of the model = ?
<u>Solution</u>:
We know that 1 feet is 12 inches
Then 2 feet is
= 24 inches
24 inches=
of a inch.
The tower is 72 times the scale of the model.
Now the actual tower is 207 feet
=
, units feet
=> 
=> 2 feet 10.5 inches.
Answer:
2
Step-by-step explanation:
x÷3 dư 1-->x=3a+1
y÷3 dư 2-->y=3b+2
x×y=(3a+1)×(3b+2)
=9ab+6a+3b+2
Mà 9ab, 6a, 3b chia hết cho 3, 2 chia 3 dư 1
==>x×y chia 3 dư 2
