Answer:The center-radius form of the circle equation is in the format (x – h)2 + (y – k)2 = r2, with the center being at the point (h, k) and the radius being "r". This form of the equation is helpful, since you can easily find the center and the radius. hoped it helped :)
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
Answer:
Step-by-step explanation:
Examples. A friend asks to borrow $300 and agrees to repay it in 30 days with 3% interest. How much interest will you earn? Simple interest is calculated on the principal, or original, amount of a loan. Compound interest is calculated on the principal amount and also on the accumulated interest of previous periods, and can thus be regarded as "interest on interest."
Answer:
(x-7)^2 + (y+3)^2 = 7
Step-by-step explanation:
The equation of a circle is
(x-h)^2 + (y-k)^2 = r^2 where (h,k) is the center and r is the radius
(x-7)^2 + (y- -3)^2 = (sqrt(7))^2
(x-7)^2 + (y+3)^2 = 7
