Answer:

$27.14

Step-by-step explanation:

Price of 1 DVD: $9.10

Price of 4 DVDs: 4 * $9.10 = $36.40

Discount: 25%

Now we find 25% of $36.40.

25% of $36.40 =

= 0.25 * $36.40

= $9.10

The 25% discount amounts to $9.10. We now subtract $9.10 from $36.40 to find the discounted price.

$36.40 - $9.10 = $27.30

Now we need to apply the 6.75% tax to $27.30.

6.75% of $27.30 =

= 0.0675 * $27.30

= $1.84

The sales tax is $1.84.

Now we add the sales tax amount to the total discounted price.

$27.30 + $1.84 = $29.14

Answer: $27.14

The voltage across the capacitor increases as a function of time when an uncharged capacitor is placed in a single loop with a r
dmitriy555 [2]

Answer:

1. Exponential

Step-by-step explanation:

The simplest RC-Circuit, that is, a capacitor and a resistor in a series configuration can be modeled by using Ohm's Law and Kirchhoff's Circuit Laws:

C \cdot \frac{dV}{dt} + \frac{V}{R} = 0

By rearranging the formula, an homogeneous linear first-order differential equation is found:

\frac{dV}{dt} + \frac{1}{R \cdot C} \cdot V = 0

Whose solution has the form of a exponential model:

V(t) = V_{o} \cdot e^{-\frac{t}{R \cdot C} }

The average profit a local store owner earns on a given day is $960 and is growing
Ostrovityanka [42]

The average profit of the local store is an illustration of an exponential function

The profit function is: y = 960 * (0.9894)^{x}

<h3>How to determine the function</h3>

From the question, we have:

  • Initial value (a) = 960
  • Rate per year (b) = 88%

An exponential function is represented as:

y = ab^x

So, the function that represents the profit per year is:

y = 960 * (88\%)^x

Divide x by 12 to get the monthly rate

y = 960 * (88\%)^{x/12}

Evaluate the exponent

y = 960 * (0.9894)^{x}

Hence, the profit function is: y = 960 * (0.9894)^{x}
