Answer:
g(5x)=0
Step-by-step explanation:
Given that g(x)=4
From the graph when x=-2 then g(x)=4
Hence 5x=-10
Now from the graph
g(-10)=0
Answer:
it should be somewhere along the lines of 2.25
Step-by-step explanation:
Answer:
Step-by-step explanation:
Given the expression
, to evaluate this, we will use one of the law of indices as shown;



Mario's error was that she did not raise the value of 4 to the power of -3. She only raised z^8 to the power of -3 when it is supposed to affect both 4 and z^8
Answer:
r~ 49.97
Step-by-step explanation:
Answer:
14.488 amperes
Step-by-step explanation:
The amplitude I of the current is given by
where
= amplitude of the energy source E(t).
Z = Total impedance.
The amplitude of the energy source is 120, the maximum value of E(t)
The total impedance is given by
where
<em>
R= Resistance
</em>
<em>L = Inductance
</em>
<em>C = Capacitance
</em>
<em>w = Angular frequency
</em>
= inductive reactance
= capacitive reactance
As E(t) = 120sin(12t), the angular frequency w=12
So
and
Finally
