11. Any company plans to connect a total of 20 pF of capacitance to a 7200-V
vesna_86 [32]

Answer:

C = 80pF

Step-by-step explanation:

The total capacitance of 4 capacitors connected in series is given by:

Ct = \frac{1}{1/C1 + /C2 + 1/C3 + 1/C4}

Ct = \frac{1}{1/C + /C + 1/C + 1/C}

Ct = \frac{1}{4/C}

Ct = \frac{C}{4}=20pF

Solving for C:

C = 4*20pF

C = 80pF

Pls ANSWER in you know the Answer
lozanna [386]

Answer:

22.5 inches

Step-by-step explanation:

To find the unit rate, you divide the amount the plant grew by the amount of weeks. We learned that the plant grew 75 inches in 100 weeks, so we divide 75/100, to get 0.75. This means that the plant grows 0.75 inches per week, so in 30 weeks, it would grow 22.5 inches. This is calculated by multiplying 0.75 by 30 weeks.

$3 for 6 bagels; $9 for 24 bagels.Determine if the rates or ratios are equivalent
Luba_88 [7]
No these are not equivelent.  24 is 4x6 so that would mean that you would have to pay $12 for those bagels and because 9 is not 3x4, 12 is making these two ratios not equivelent.

The accompanying table shows the value of a car over time that was purchased for
Dafna1 [17]

The value of the car after 11 years is $3137.18

<h3>exponential function</h3>

An exponential function is in the form:

y = abˣ

where a is the initial value of y, b is the factor, y, x are variables.

Let y represent the value of the car in dollars after x years. From the table:

When x  = 0, y = 12700, hence:

  • 12700 = ab°
  • a = 12700

When x = 2, y = 9849, hence:

  • 9849 = 12700b²
  • b = 0.8806

The exponential function is:

y = 12700(0.8806)ˣ

For 11 years:

y = 12700(0.8806)¹¹ = 3137.18

The value of the car after 11 years is $3137.18

A swimming pool is to be drained. The pool is shaped like a rectangular prism with length 30 ft, width 18 ft, and depth 4 ft. Su
Licemer1 [7]

Answer:

10 hours (I am not positive)

Step-by-step explanation:

We first want to find the volume of pool which is 30 x 18 x 4 = 2160.

Then you are going to divide by 216 to find how many hours it takes to drain the whole pool. (I'm not that big of an expert)
