Use Ohm’s law to find the resistance of the light bulb if you had a 20 volt battery and 0.57 amps of current. Show your work for
aleksley [76]
For this case we have the following equation:
 V = I * R
 Where,
 V: voltage
 I: current
 R: resistance
 By clearing R we have:
 R = V / I
 Substituting the values:
 R = (20) / (0.57)
 R = 35.09 Ohms
 Answer:
 
The resistance of the light bulb is:
 
R = 35.09 Ohms

A polynomial has been factored, as shown below: f(x) = (x − 6)(x + 5)(x − 9) What are the zeros of the polynomial? (5 points)
soldi70 [24.7K]

<span>x=6</span>, <span>x=−5</span> or <span>x=9</span>

Explanation:

<span><span>f<span>(x)</span></span>=<span>(x−6)</span><span>(x+5)</span><span>(x−9)</span></span>

If all of the linear factors are non-zero, then so is their product <span>f<span>(x)</span></span>.

If any of the linear factors is zero, then so is their product <span>f<span>(x)</span></span>.

The average daily high temperature in °C) in Karachi, Pakistan, on the tth day of the year is
kvasek [131]

Answer:

The highest would be 34 degrees Celsius and the lowest would be 24 degrees Celsius.

Step-by-step explanation:

What I did was make a graph. The 29 in the beginning of the function represents the vertical shift, meaning the "midline" would be y = 29. The -5 after the 29 represents the amplitude. From there, you can go 5 under 29 (24 degrees Celsius) and 5 over 29 (34 degrees Celsius).
