A 0.143-Henry Inductor is connected in series with a variable resistor to a 208-volt 400-cycle source. For what value of capacit
aleksandr82 [10.1K]

Answer:

A.)359.2, B.)2.5 uf

Step-by-step explanation:

E / I = R

208 / 1.04 = 200 ohms

2*pi*f*L = Xl

6.28*400*.143 = 359.2 ohm

1 / (2*pi*f*Xc) = c

1 /(6.28*400*159.2) = 2.5 uf

Jonathon has a bag that contains exactly one red marble (r), one yellow marble (y), and one green marble (g). He chooses a marbl
wariber [46]

Answer:

          [ry, yr, gy, yg, rg, gr]-Any three picks from this sample space.

Step-by-step explanation:

-The bag contains exactly 1r, \ 1y, \ 1g \ marbles.

-He picks one ball without looking, and chooses a second ball without replacing the first:

  • If the first is red, the the second is either yellow or green,
  • If the first is a yellow, then the second can be red or green,
  • If the first is green, then the second can be a red or yellow.

The sample space of the second pick is therefore:

                               [ry, yr, gy, yg, rg, gr]

Hence, any three picks from the sample space are correct possible outcomes.

Alexis invests $475 in a bank account that earns 1.25% interest compounded annually. Which function models the growth of her inv
olchik [2.2K]
Answer: The function that modes this situation would be: y = 475(1 + .0125)^x.

This is an example of an exponential equation. These equations are always in the form y = ab^x.

The a value is the starting value. The b value is the interest rate. The x value is the number of years.

The only thing to be careful about is the rate. We are adding 1.25% or 0.125. Make sure that you are adding 1 whole to the 1.25% and don't just use 0.125.

sergey [27]

Answer:

Let n be the number of questions you got right. Then

30-n equals the number of questions you got wrong.

So:

A) 20n-10(30-n)=180

30n-300=180

30n=480

n=16

30-n=14

B)You got <u>16</u> questions right and <u>14</u> questions wrong.
