It will take approximately 39.532 days for $9500 to earn $800 at an annual interest rate of 8.25%.

To find the number of days it will take for $9500 to earn $800 at an annual interest rate of 8.25%, we need to use the formula for simple interest:

Interest = Principal * Rate * Time

In this case, we are given the interest ($800), the principal ($9500), and the annual interest rate (8.25%). We need to solve for time.

Let's denote the time in years as "t". Since we're looking for the number of days, we'll convert the time to a fraction of a year by dividing by 365 (assuming a standard 365-day year).

$800 = $9500 * 0.0825 * (t / 365)

Simplifying the equation:

800 = 9500 * 0.0825 * (t / 365)

Divide both sides by (9500 * 0.0825):

800 / (9500 * 0.0825) = t / 365

Simplify the left side:

800 / (9500 * 0.0825) ≈ 0.1083

Now, solve for t by multiplying both sides by 365:

0.1083 * 365 ≈ t

t ≈ 39.532

Therefore, it will take approximately 39.532 days for $9500 to earn $800 at an annual interest rate of 8.25%.

Answer:

The answer is option D.

Equation of a line is y = mx + c

m = slope

c = intercept on y axis

y-4= -2/3 (x-6)

y = -2/3x + 4 + 4

y = -2/3x + 8

From the above equation

m= -2/3

Since the lines are perpendicular the slope of the line is the negative inverse of the original line.

so m = 3/2

Equation of the line using point (-2 , -2) is

y + 2 = 3/2(x+2)

y = 3/2x + 3 - 2

y = 3/2x + 1

That's the last option

Hope this helps

The linear equation with the given characteristics is given by:

\(y = \frac{3}{2}x + 1\)

It is given by:

y = mx + b.

In which:

When two lines are perpendicular, the multiplication of their slopes is -1, hence:

\(-\frac{2}{3}m = -1\)

\(2m = 3\)

\(m = \frac{3}{2}\)

Then:

\(y = \frac{3}{2}x + b\)

It passes through the point (-2, -2), hence:

\(-2 = \frac{3}{2}(-2) + b\)

\(-3 + b = -2\)

\(b = 1\)

Hence, the equation is:

\(y = \frac{3}{2}x + 1\)

Answer:

y = 2/3x + 4/3

Step-by-step explanation:

you need to know the slope of the line -2x + 3y = -6 because parallel lines have the same slopes

let's put the equation in y=mx+b format (slope-intercept format)

-2x + 3y = -6

add 2x to each side to get:

3y = 2x - 6

divide each side by 3 to get:

y = 2/3x - 2

the equation now shows us the slope is 2/3 and the y-intercept is (0,-2)

now we use y=mx+b again and use the point (-2,0) and the m=2/3 to get the y-intercept ('b' value) of the equation that is parallel:

0 = 2/3(-2) + b

0 = -4/3 + b

b = 4/3

equation would be:

y = 2/3x + 4/3

We are given these three people age below:

We define the age of Jim as any variable, because the problem doesn't give any specific age. I will define Jim's age as x.

Next, Carla is 5 years older than Jim. That means if Carla is 5 years older, her age would be x+5.

Then Tomy is 6 years older than Carla. That means the age would be 6+(x+5).

The sum of their three ages is 31 years old. That means we add all these ages and equal to 31.

\( \large{x + x + 5 + 6 + x + 5 = 31}\)

Combine like terms and solve for x.

\( \large{3x + 16 = 31} \\ \large{3x = 31 - 16} \\ \large{3x = 15} \\ \large{x = 5}\)

Then we substitute the value of x in ages to find these three people ages.

Answer

The conjugate which is 3 - √7 is also a root of f(x).

The root of a polynomial function f(x) is the value of x for which f(x) = 0.

Now if a polynomial function has a root x = a + √b then the conjugate of x which is x' = a - √b is also a root of the function, f(x).

Given that the polynomial function, f(x), with rational coefficients has roots

3 + √7, then by the above, the conjugate which is 3 - √7 is also a root of f(x).

So, 3 - √7 is also a root of f(x).

whats the definition?

Step-by-step explanation:

In a right triangle, the length of one leg is seven more than the other leg, and the hypotenuse is eight more than the shorter leg. By applying the Pythagorean theorem, we can determine the length of the hypotenuse, which is found to be 13 units.

Let's denote the shorter leg of the right triangle as x.

According to the given information, the longer leg is seven more than the shorter leg, so its length is x + 7.

The hypotenuse is eight more than the shorter leg, so its length is x + 8.

We can use the Pythagorean theorem to relate the lengths of the legs and the hypotenuse:

x^2 + (x + 7)^2 = (x + 8)^2

Expanding the equation:

x^2 + x^2 + 14x + 49 = x^2 + 16x + 64

Simplifying the equation:

2x^2 + 14x + 49 = x^2 + 16x + 64

Rearranging terms:

x^2 - 2x - 15 = 0

Now, we can factor the quadratic equation:

(x - 5)(x + 3) = 0

Setting each factor equal to zero:

x - 5 = 0  -->  x = 5

x + 3 = 0  -->  x = -3

Since lengths cannot be negative, we discard x = -3.

Therefore, the length of the shorter leg is x = 5, the length of the longer leg is x + 7 = 12, and the length of the hypotenuse is x + 8 = 13.

So, the length of the hypotenuse is 13.

Answer:

33

Step-by-step explanation:

Start by adding the 3 to the other side (2/3x=22)

Then, you divide 2/3 to cancel it out. To do that, multiply 22 by 3/2 which equals to 33.

Answer:

2/3x - 3 = 19

We first isolate the variable and solve for x, (we get rid of any constants first in the process)

2/3x - 3 = 19 the three is the constant so we get rid of it by adding three to both sides.

2/3x - 3 = 19

+3            +3

2/3x = 22

Step-by-step explanation:

Given

x² + 2x - 3 = 0 ( add 3 to both sides )

x² + 2x = 3

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(1)x + 1 = 3 + 1

(x + 1)² = 4 ( take the square root of both sides )

x + 1 = ± \(\sqrt{4}\) = ± 2 ( subtract 1 from both sides )

x = - 1 ± 2

Thus

x = - 1 - 2 = - 3

It will take about 9.5 months (or 10 months rounded up) for the rabbit population to reach 5,800.

Let's use the formula for exponential growth to solve this problem:

N = N0 * 2^(t/k)

Where:

N0 = initial population (8 rabbits)

N = final population (5,800 rabbits)

k = doubling time (1 month)

t = time in months (what we're trying to find)

Substituting the values we have:

5,800 = 8 * 2^(t/1)

Dividing both sides by 8:

725 = 2^(t/1)

Taking the logarithm of both sides (base 2):

log2(725) = t/1

t = log2(725) ≈ 9.515

So it will take about 9.5 months (or 10 months rounded up) for the rabbit population to reach 5,800.

Given the matrix expression A = (a 0 3(a-b) b) = (1 0 3 1) (a 0 0 b) (1 0 -3 1), we want to compute the matrix power Ak using the factorization A = PDP^-1.

First, we need to find the matrices P and D. The matrix D is a diagonal matrix consisting of the eigenvalues of A, which are a, b+3a, and b-3a. The matrix P is the matrix whose columns are the eigenvectors of A, which can be found by solving the system (A - λI)x = 0 for each eigenvalue λ.

Solving for each eigenvalue, we get λ1 = a with eigenvector (0,1), λ2 = b+3a with eigenvector (-3,1), and λ3 = b-3a with eigenvector (1,1). Thus, we have:

D = (a 0 0

0 b+3a 0

0 0 b-3a)

P = (0 -3 1

1 1 1

0 0 1)

To compute Ak, we can use the formula A^k = PD^kP^-1. Since D is a diagonal matrix, we can easily compute D^k by raising each diagonal entry to the power of k. Thus, we get:

D^k = (a^k 0 0

0 (b+3a)^k 0

0 0 (b-3a)^k)

Multiplying out the matrices P and P^-1, we get:

P^-1 = (1/3 -1/3 0

-1/3 2/3 -1/3

0 -1/3 1/3)

P^-1AP = D

Multiplying both sides by P^-1, we get:

A = PDP^-1

Now, substituting D^k into the formula A^k = PD^kP^-1, we get:

A^k = P D^k P^-1

Substituting the matrices P, P^-1, and D^k, we get the expression for Ak as:

Ak = (1/3)((b+3a)^k - (b-3a)^k) (1 -3(b-3a)^k/(b+3a)^k - 3(b+3a)^k/(b-3a)^k 1) (a 0 0 b)

Therefore, we have the expression for Ak.
