the points (3, 9) and (-3, -9) ate plotted on the coordinate plane using the equation y=a . x ... - did
slava [35]

See the explanation

<h2>Explanation:</h2><h2></h2>

Here we have the following points:

(3,9) \ and \ (-3,-9)

The point-slope form of the equation of a line is:

y=ax+b \\ \\ \\ a:Slope \\ \\ b:y-intercept

So the slope can be found as:

a=\frac{-9-9}{-3-3} \\ \\ a=\frac{-18}{-6} \\ \\ a=3

So:

y=3x+b \\ \\ \\ Finding \ b: \\ \\ For \ x=3, \ y=9: \\ \\ \\ So: \\ \\ 9=3(3)+b \\ \\ b=9-9 \\ \\ b=0

So the equation is finally:

y=3x

This line passes through and is shown below.

In a parallel circuit, ET = 208 V, R = 33 kΩ, and XL = 82 kΩ. What is the apparent power?
jeka94

Answer:

Apparent power is 1.413Volt-Amps.

Step-by-step explanation:

We are given that in a parallel circuit,E_{T}=208V,R=33kΩ and X_{L}=82kΩ.

And we are asked to find apparent power.

Apparent power is the combination of true power and reactive power.

In other words, we can say that in a power triangle apparent power is the hypotenuse where as true power and reactive powers are sides.

Let us find true power , reactive power first and the using Pythagorean theorem we can find apparent power.

True power=\frac{E_{T}^{2}}{R}=\frac{208^{2}}{33000}=1.311watts

Reactive power=\frac{E_{T}^{2}}{X_{L}}=\frac{208^{2}}{82000}=0.528VARs

Hence apparent power=\sqrt{1.311^{2}+0.528^{2}} =1.413VA

Find x (PLS HURRY ITS URGENT) ​
skelet666 [1.2K]

Answer:

<h2>         x = 85° </h2>

Step-by-step explanation:

m∠ADC = 180° - 95°             {a straight angle}

m∠ABC =  180° - x             {a straight angle}

m∠ADC + m∠ABC = 180°     {a quadrilateral inscribed in a circle}

180 - 95° + 180 - x = 180°

     85° - x = 0

        <u>x = 85° </u>
