Given : supply voltage = 120V;60 Hz

Inductive Reactance (X_{L}) = 40 Ω

The inductive reactance is given by the formula, X_{L}=Lw, where L is inductance and w is given by formula, w = 2\pi(frequency)

Apply this, we can say that, L = \frac{X_{L}}{2\pi (frequency)}  = \frac{40}{2(3.14)(60)} = 0.106157 H = 106.157 mH

The trick here is to notice that all 3 terms can be div. by 2:

2(x^2 + x - 12)

Note that -12 factors into -3 * 4 or -4 * 3.  Thus,

x^2 + x - 12 = (x-4)(x+3), and so <span>2x2 + 2x − 24 = 2(x-4)(x+3).</span>

The value is 5.48 or 5 inches because the parallelograms have equal opposite  sides, so therefore the opposite angles are equal too so the
sinx=5.6/10
x=34
then sin34=h/9.8
h=5 inches.

Find the first 4 terms of the geometric sequence a1=40 and r=0.5
DedPeter [7]
For the answer to the question above, 
a1 = 40 
<span>a2 = 20 </span>
<span>a3 = 10 </span>
<span>.. </span>
<span>aN = (1/2^N-1) a1 { in general aN= (r^N-1) A1 </span>

<span>a5 = (1/2^4) 40 = 40/16 = 2.5
</span>
So the answer to your question is 2.5

Aleks04 [339]

Answer:

31 vacuums

Step-by-step explanation:

1800 = 250 + 50v

1800 - 250 = 50v

50v = 1550

v = 1550 / 50

v = 31

He sold 31 vacuums.
