The half-life of the substance is of 10.31 years.

What is exponential?

The exponential is an example of a mathematical function that is useful in determining if something is increasing or decreasing exponentially is the exponential function. As implied by its name, an exponential function uses exponents. But take note that an exponential function does not have a variable as its exponent and a constant as its base (if a function has a variable as the base and a constant as the exponent then it is a power function but not an exponential function).

a sample of a radioactive substance decayed to 93% of its original amount after a year.

The half-life is t for which:

exp(-0.067 t) = (0.5)

ln(0.5) = -0.067 t

t = 10.31 years.

Hence the half-life of the substance is of 10.31 years.

The minimum cost for the area can be fenced is $1920

It is given that the area of the rectangular field is 900 m²

Let the length of one side of the field be x m

Therefore, the length of the other side will be

900/x

The perimeter of the rectangular field

= 2(length + breadth)

= 2(x + 900/x)

= 2x + 1800/x  m

Therefore, the cost of fencing will be

$(32x + 28800/x )

Let f(x) = 32x + 28800/x

We need to minimize f(x)

Differentiating with respect to x and equating it to 0 gives us

32 - 28800/x² = 0

or, x² = 28800/32

or, x² = 900

or, x = 30

This is because the length cannot be negative hence -30 cannot be a value

Now

f''(x) = 57600/x³

f''(30) = 2/1333

Since f"(x) is positive, x = 30 is the minimum value of x for which the cost is minimum.

Hence, the minimum cost will be

f(30)

= 960 + 960

= $1920

Answer:

Below

Step-by-step explanation:

Question 1:

The quadratic equation is of the form ax^2 + bx + c = 0, where a, b, and c are constants. If one solution of the equation is 7-13i, the other solution must be the complex conjugate of 7-13i, which is 7+13i. To find the complex conjugate of a complex number, you simply need to change the sign of the imaginary part of the number. In this case, the complex conjugate of 7-13i is 7+13i.

Question 2:

1. (4-3i) (-7+21)

To add two complex numbers, we need to add their real parts and imaginary parts separately. In this case, we have:

(4-3i) (-7+21)

= (4 - 7) + (-3i + 21)

= -3 + 18i

2. (-7+6i)+(2-3i)+(4+5i)

To add multiple complex numbers, we can add them one at a time using the same procedure as before. In this case, we have:

(-7+6i)+(2-3i)+(4+5i)

= (-7+2) + (6i - 3i) + (4 + 5i)

= -5 + 3i + 4 + 5i

= -1 + 8i

3. (-6-i)/4-2i

To divide two complex numbers, we need to multiply the numerator and denominator by the complex conjugate of the denominator. In this case, we have:

4. (-6-i)/4-2i

= (-6-i)(4+2i)/(4-2i)(4+2i)

= (-24 - 2i + 6i - i^2)/20

= (-24 + 4 -1)/20

= (-21)/20

= -1.05 - 0.05i

5. (-2-7i)(-2+7i)

To multiply two complex numbers, we use the FOIL method, which involves multiplying the First, Outer, Inner, and Last terms separately and then adding the results. In this case, we have:

(-2-7i)(-2+7i)

= (-2 * -2) + (-2 * 7i) + (-7i * -2) + (-7i * 7i)

= 4 + (-14i) + 14i + 49

= 4 + 49

= 53

6. (5-3i)-(-2-6i)

To subtract two complex numbers, we need to add the first number to the opposite of the second number. In this case, we have:

(5-3i)-(-2-6i)

= (5-3i) + (2 + 6i)

= 7 + 3i

This is the final answer for each of the problems.

Answer:

To find the slope-intercept form of the line that passes through the points (−2, 6) and (−1, 18), we can use the slope-intercept form y = mx + b, where m is the slope of the line and b is the y-intercept.

First, we need to find the slope of the line. The slope of a line is calculated using the formula m = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are the coordinates of two points on the line. Substituting the coordinates of the points given in the problem, we have:

m = (18 - 6) / (−1 - (−2)) = 12 / 3 = 4

Next, we need to find the y-intercept of the line. The y-intercept is the point where the line crosses the y-axis, which has an x-coordinate of 0. Substituting the slope and the coordinates of one of the points given in the problem, we can solve for b:

y = mx + b

6 = 4 * (−2) + b

6 = −8 + b

b = 6 + 8 = 14

Therefore, the slope-intercept form of the line that passes through the points (−2, 6) and (−1, 18) is y = 4x + 14.

What is the percentage?

A percentage that represents a tenth of a quantity. One percent, denoted by the symbol 1%, is equal to one-hundredth of something; hence, 100 percent denotes the full thing, and 200 percent designates twice the amount specified. A portion per hundred is what the percentage denotes. The percentage refers to one in a hundred. The % sign is used to denote it.

the risk-free return during the sample period was 3%.

performance evaluation for sooner stock fund.

Expected return of Sooner Stock Fund = E(Rp) = 20%

Beta of stock = 1.8

risk free rate Rf = 3%

a) Cost of debt, I = 4.25%(annual)

b) After tax cost of debt = 3.315%

c) After tax cost of debt of 3.135% is more relevant.

Given:

FV = 100

Semiannual bond issued 3 years ago

Maturity = 27

Price, PV = 104

coupon rate = 4.5%

Tax rate = 22%

a) Semiannual bond issued 3 years ago

Maturity, n = 27 years × 2 = 54

Coupon C = 4.5%/2×100 = 2.25

Now,

Pretax cost of debt,

Cost of debt, I = [C+(FV-PV)/n] / (FV+PV)/2

= [2.25 +(100 - 104)/54] / [ 100+1040/2

= 2.12%

= 2.12×2

Cost of debt, I = 4.25%(annual)

b) After tax cost of debt = cost of debt × (1-T)

We can determine that we need 216 mL of 100% alcohol and 384 mL of 50% alcohol using the percentage by volume of the solutions that have been provided.

Volume/volume percentage, often known as v/v percent or %v/v, is a unit used to express how much of a substance is present in a solution.

It is defined as the volume of the solute divided by the sum of the volumes of the solution, multiplied by one hundred.

So, we know that:

A + B = 600 mL

We also understand that the final solution's total alcohol content must equal:

0.68 * 600 mL = 408 mL

So, it follows that:

0.50 * A + B = 408 mL

We can infer the following from the first equation:

A = 600 mL - B

In the second equation, using that A, we obtain:

0.50 * (600 mL - B) + B = 408 mL

300 mL - 0.50 B + B = 408 mL

The result of rearranging this equation is:

B - 0.50 * B = 408 mL - 300 mL

0.50 * B = 108 mL

B = 108 mL / 0.50

B = 216 mL

A = 600 mL - 216 mL = 384 mL

Therefore, we can determine that we need 216 mL of 100% alcohol and 384 mL of 50% alcohol using the percentage by volume of the solutions that have been provided.

Answer:

To determine which region represents the solution to a system of linear inequalities, you need to graph each inequality on the same coordinate plane and then find the intersection of the regions that satisfy each inequality. This intersection is the solution to the system of linear inequalities, as every point in this region satisfies all of the inequalities in the system.

To graph the solution, you can use a number line for each variable and plot the inequalities as points or lines on the coordinate plane. For example, if the system of linear inequalities is given by the equations y > 2x + 3 and y < -x + 5, you can plot the lines y = 2x + 3 and y = -x + 5 on the coordinate plane and find the intersection of the two lines. This intersection represents the solution to the system of linear inequalities, as every point in this region satisfies both inequalities.

Another way to find the solution to a system of linear inequalities is by using algebra to solve the system. This involves writing the equations in standard form, eliminating variables, and solving for the remaining variable. The solution can then be written as a set of ordered pairs that represent the points on the coordinate plane that satisfy the system of linear inequalities.

In either case, the solution to a system of linear inequalities is the region of the coordinate plane that satisfies all of the inequalities in the system.

The equation of the line that passes through the point (−11,−14) is y = x - 3.

What is the slope of the line?

A line's steepness can be determined by looking at its slope. The slope is calculated mathematically as "rise over run" (change in y divided by change in x).

We have,

The line that passes through the point (−11,−14)

With Slope (m) = 1,

The general equation of a straight line is

y = mx + c,

where m is the gradient, and y = c is the value where the line cuts the y-axis. This number c is called the intercept on the y-axis.

so here,

y = mx + c,

(-14) = 1(-11) + c

c = -14 + 11

c = -3

The equation becomes:

y = x - 3.

Hence, the equation of the line that passes through the point (−11,−14) is

y = x - 3.
