Due to unexpected circumstances, you take out a loan for $5,000 to pay for a lawyer. You agree to pay it back over the next 5 years at a rate of 22.5% (because your credit score is really really low). At the end of the 5 years, how much did this "unexpected circumstance" end up costing you in all?

The solution for the given expression is given below:

a. vertical asymptote. b. the graph of f will pass through the point (0, 15). c. to keep f(x) within 0.01 units of 7, we need to keep x between 2.9986 and 3.0014.

What is expression?

In general, an expression is a combination of symbols, numbers, and/or operators that can be evaluated to produce a value. In programming, an expression typically refers to a sequence of one or more operands and operators that can be evaluated to produce a single value.

a. When x = 3, the denominator of f(x) becomes zero, and therefore f(3) is undefined (or does not exist). This is called a vertical asymptote.

b. To plot the graph of f, we can factor the numerator as follows:

f(x) = (4x-3)(x-5)/(x-3)

The graph of f will have a vertical asymptote at x = 3, and the function will be undefined at that point. The factor (4x-3)(x-5) has zeros at x = 3/4 and x = 5, so the graph will cross the x-axis at those points. We can also find the y-intercept by setting x = 0:

f(0) = (4(0)-3)(0-5)/(0-3) = 15

Therefore, the graph of f will pass through the point (0, 15).

c. The limit of f(x) as x approaches 3 is given by:

lim[x→3] f(x) = lim[x→3] (4\(x^2\)-17x+15)/(x-3) = 7

To find how close to 3 we need to keep x in order for f(x) to be within 0.01 units of 7, we can use the definition of a limit:

|f(x) - 7| < 0.01

This inequality can be rewritten as:

-0.01 < f(x) - 7 < 0.01

\(-0.01 < (4x^2-17x+15)/(x-3) - 7 < 0.01\)

Solving for x using this inequality is difficult, but we can use a graphing calculator or a numerical method to find the values of x that satisfy it. For example, using a graphing calculator, we can graph the function (4x^2-17x+15)/(x-3) and the horizontal lines y = 7.01 and y = 6.99, and find the values of x where the graph intersects those lines. We get:

x ≈ 3.0014 and x ≈ 2.9986

Therefore, to keep f(x) within 0.01 units of 7, we need to keep x between 2.9986 and 3.0014.

Similarly, to find how close to 3 we need to keep x in order for f(x) to be within 0.0001 units of 7, we can use the inequality:

|f(x) - 7| < 0.0001

This inequality can be rewritten as:

-0.0001 < f(x) - 7 < 0.0001

\(-0.0001 < (4x^2-17x+15)/(x-3) - 7 < 0.0001\)

Using a similar method as before, we can find that we need to keep x between approximately 2.99994 and 3.00006 to keep f(x) within 0.0001 units of 7.

To keep f(x) arbitrarily close to 7 just by keeping x close to 3 but not equal to 3, we can use the fact that the function approaches 7 as x approaches 3 from both sides. This means that we can make f(x) as close to 7 as we want by choosing a small enough positive or negative deviation from 3.

If you doubled a penny every day, you would have $5,368,709.12

You can see that the decision is rather straightforward: having a single penny that doubles every day for a month are preferable to receiving $1 million upfront. This is due to compound interest's strength.

The interest earned on savings that are computed using both the original principal and the interest accrued over time is known as compound interest.

It is thought that Italy in the 17th century is where the concept of "interest on interest" or compound interest first appeared. It will accelerate the growth of a total more quickly than simple interest, which is solely calculated on the principal sum.

Money multiplies more quickly thanks to compounding, and the more compounding periods there are, the higher the compound interest will be.

If I double this particular penny every day, I would have 30 extra pennies, plus my original one. I have $0.31 literal dollars

Farmer Ed has 3,000 meters of fencing and wants to enclose a rectangular plot that borders on a river.The largest area that can be enclosed is 750,000 square meters.

To get the largest area that can be enclosed, we have to find the dimensions of the rectangular plot. Let's assume that the width of the rectangle is x meters.The length of the rectangle can be found by subtracting the width from the total length of fencing available:L = 3000 - x. The area of the rectangle can be found by multiplying the length and width:Area = L × W = (3000 - x) × x = 3000x - x²To find the maximum value of the area, we can differentiate the area equation with respect to x and set it equal to zero.

Then we can solve for x: dA/dx = 3000 - 2x = 0x = 1500. This means that the width of the rectangle is 1500 meters and the length is 3000 - 1500 = 1500 meters.The area of the rectangle is therefore: Area = L × W = (3000 - 1500) × 1500 = 750,000 square meters. So the largest area that can be enclosed is 750,000 square meters.

The area of the square is changing at 12√2 + 2√2t square inches/minute when the circle is increasing at 1 in/min.

Let us find the relationship between r and s using the Pythagorean theorem. Since the square is inscribed in the circle, the diameter of the circle is equal to the diagonal of the square.

2r = s√2
Squaring both sides, we get:
4r² = 2s²or s² = 2r²
Dividing by 2 on both sides, we get:
s²/2 = r²
Differentiating both sides with respect to t, we get:
ds²/dt = 2r (dr/dt)
Dividing both sides by 2s, we get:
ds/dt = r (dr/dt) / s

Substituting r² = s²/2,

\(ds/dt = r (dr/dt) / √2s2s ds/dt = r (dr/dt)s ds/dt = (r/2) (dr/dt)2s ds/dt = r (dr/dt) or dA/dt = 2s ds/dt = 2r (dr/dt)\)

Now, substituting r² = s²/2,

dA/dt = 2s ds/dt = 2(√2 s) (dr/dt) = 2(√2) r (dr/dt)

Now, substituting dr/dt = 1 in/min and r = 6 in (since the circle is increasing at 1 in/min, the radius after t minutes is 6 + t),

dA/dt = 2(√2) (6 + t) (1) = 12√2 + 2√2t square inches/minute

Therefore, the area of the square is changing at a rate of 12√2 + 2√2t square inches/minute.

The magnitude of the vector QP is √73.

To find the component form of the vector QP, we need to subtract the coordinates of point P from the coordinates of point Q. The component form of a vector is represented as (x, y), where x and y are the differences in the x-coordinates and y-coordinates, respectively.

Given that P = (4, 1) and Q = (-4, 4), we can calculate the component form of the vector QP as follows:

x-component of QP = x-coordinate of Q - x-coordinate of P

                 = (-4) - 4

                 = -8

y-component of QP = y-coordinate of Q - y-coordinate of P

                 = 4 - 1

                 = 3

Therefore, the component form of the vector QP is (-8, 3).

To find the magnitude of the vector QP, we can use the formula:

Magnitude of a vector = √(\(x^2 + y^2\))

Substituting the x-component and y-component of QP into the formula, we get:

Magnitude of QP = √((\(-8)^2 + 3^2\))

              = √(64 + 9)

              = √73

Therefore, the magnitude of the vector QP is √73.

In summary, the component form of the vector QP is (-8, 3), and its magnitude is √73. The component form gives us the direction and the magnitude gives us the length or size of the vector.

a. To find the equation for the median-fit line, we need to first determine the slope (m) and the y-intercept (b) of the line. We can use the following formulas to calculate these values:

m = (nΣxy - ΣxΣy) / (nΣx^2 - (Σx)^2)

b = median y - m(median x)

Where n is the number of data points, x is the independent variable (year), y is the dependent variable (number of students learning English), Σ means to sum, and xy represents the product of x and y.

For this dataset, we have 5 data points, so n = 5.

x = 2003, 2004, 2005, 2006, 2007

y = 1.600, 1.599, 1.592, 1.570, 1.560

Σx = 10,015

Σy = 7,966

Σxy = 31,948

Σx^2 = 40,307

m = (531948 - 100157966)/(5*40307 - 10015^2) = -0.007

median x = 2005

median y = 1592

b = 1592 - -0.007 * 2005 = 1597.014

The equation for the median-fit line is:

y = -0.007x + 1597.014

b. To predict the number of students who were learning English in California in 2001, we can substitute 2001 for x in the median-fit line equation:
