Answer:
The total resistance of these three resistors connected in parallel is 
Step-by-step explanation:
The attached image has the circuit for finding the total resistance. The circuit is composed by a voltage source and three resistors connected in parallel: 
, 
and 
.
<u>First step: to find the source current</u>
The current that the source provides is the sum of the current that each resistor consumes. Keep in mind that the voltage is the same for the three resistors (
, 
and 
).
The total current is:
The total resistance (
) is the source voltage divided by the source current:
Now, replace 
by the previous expression and the total resistance would be:
Simplify the expression and you must get:
The last step is to replace the values of the resistors:
Thus, the total resistance of these three resistors connected in parallel is
Given that:
<span>22a(22b)=16
484ab=16
thus
ab=16/484
ab=4/121
thus given that
ab=4/121
then
a=4 and b=1/121
hence
4+1/121
=4 1/121</span>
We have the following equation:
V = kr ^ (2) h
For cylinder A we have:
251.2 = k * ((4) ^ (2)) * (5)
Let's clear k:
k = 251.2 / (((4) ^ (2)) * (5))
k = 3.14
For cylinder B we have:
V = 3.14 * ((3) ^ (2)) * (9)
V = 254.34 in ^ 3
Answer:
the volume of cylinder B is:
V = 254.34 in ^ 3
If and only if it is a proportional relationship, the problem can be solved by creating a proportion of B1/T1=B2/T2. This can also be expressed as 4.5/3.5=5.4/x given the values. You must cross multiply, so 4.5x=3.5(5.4). This simplifies to x=4.2. So, the tail length would be 4.2 feet.
Hope this helps.
