Answer:

answer is y = 3/4x - 5

Step-by-step explanation:

picture below.

The 3/4 comes from the line. You would use rise over run to find the slope, which in this case is 3/4. and the -5 is basically the y-intercept

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

after two years on the job, an engineer salary was $60,000. after seven years on the job, her salary was $66,000. let y represen
galina1969 [7]

Answer: y = 1200m + 57,600

Step-by-step explanation: To be a line, let's say that x is the numbers of years on the job and y the salary.

So, we have (2,60000) and (7,66000)

y = mx + b

66000 = 7m + b

60000 = 2m + b (-)

________________________

6000 = 5m

m = 6000/5 = 1200

60000 = 2m + b

60000 = 2.1200 + b

60000 = 2400 + b

b = 60000 - 2400

b = 57600

y = mx + b

y = 1200m + 57,600

For the data set 100, 100, 104, 107, 107, the mean is 103,. What is the mean absolute deviation
Anna35 [415]

Answer:

Mean Absolute Deviation is 3.

Step-by-step explanation:

103-100=3

103-100=3

103-104=1

103-107=4

103-107=4

3+3+1+4+4=15/ the five numbers

15/5= 3
