×=13
(3x-3)/4=(2x+1)/3 CROSS MULTIPLY
3(3x-3)=4(2x+1) DISTRIBUTE
9x-9=8x+4 ADD 9 TO BOTH SIDES
9x=8x+13 SUBTRACT 8X FROM BOTH SIDES

x=13

PROOF
3(13)-3=36
36÷4=9

2(13)+1=27
27÷3=9

Find the integral of 3/sqrt of 1-4x^2

erastovalidia [21]

$\int {\frac{3}{\sqrt{1-4x^{2}}}} \, dx$
$= 3\int {\frac{1}{\sqrt{1-4x^{2}}}} \, dx$
$= 3\int {\frac{1}{\sqrt{4(\frac{1}{4} - x^{2})}}} \, dx$
$= \frac{3}{2}\int {\frac{1}{\sqrt{\frac{1}{4} - x^{2}}}}\, dx$

$= \frac{3}{2}sin^{-1}(2x) + C$

Change the decimal 0.0112 to a fraction. A. 112/10,000 B. 112/100 C. 112/100,000 D. 112/1,000

ehidna [41]

The answer would be A. 112/10,000.

The answer would be that because: If we do 0.1001, it wouldn't be 112/100 or 112/1,000, and 112/100,000 is too big.

Hope this helped! c:

HELP PLEASE!!!!!!

The problems of physics that are given here can be solved using Ohms laws. As per the Ohms law, we can write
Resistance = Current/Voltage.
Now coming to the questions that are given.
1. In this question,
Current = 15 amperes
Voltage = 5 volts
Then
Resistance = 5/15
   = 1/3
   = 0.33 ohms
So the resistance of the tube will be 0.33 ohms
2. Given information's are noted below
Current = 2 amperes
Voltage = 120 volts
Resistance = 120/2
   = 60 ohms
So 60 ohms of resistance is present in the bulb.
3. Given information's
Current = 250 watt
Voltage = 240 volts
Resistance = 250/240
   = 25/24
   = 1.04 ohms.
The radio will draw 1.04 ohms.
