Answer:
Compounded Semiannually: [tex](1.03454)^t[/tex] and APR = 3.454%
Compounded Quarterly: [tex](1.03469)^t[/tex] and APR = 3.469%
Step-by-step explanation:
Compound Interest Formula:The Compound Interest Formula is as follows: [tex]A = P(1 + \frac{r}{n})^{nt}[/tex], which can also be written as: [tex]A = P((1 + \frac{r}{n})^n)^t[/tex], using properties of exponents. This is crucial since we want one value inside the parenthesis to calculate the APR (Annual Percentage Rate). Since we want the APR, the only thing we really care about is the [tex](1 + \frac{r}{n})^n[/tex], but this is going to be our APR + 1.
In the question, it's formatted as: [tex]b^t[/tex], and this inside part is going to be our b, so: [tex]b = (1 + \frac{r}{n})^n[/tex], and to calculate the APR we simply subtract 1.
Calculating APR:Compounded semiannually means the interest is compounded twice a year, so n = 2. We are also given the interest to be 3.425% which in decimal form is 0.03425
Plugging this into the formula stated above we get: [tex]b = (1 + \frac{0.03425}{2})^2 \approx 1.03454[/tex]
So we have the form:
[tex](1.03454)^t[/tex]
With our APR simply being the base - 1:
[tex]APR \approx 0.03454[/tex]
We multiply this by 100 to get it in percentage form:
[tex]APR\approx 3.454\%[/tex]
Compounded quarterly means the interest is compounded four times a year, so n = 4. Plugging in known values we get:
[tex]b = (1 + \frac{0.03425}{4})^4 \approx 1.03469[/tex]
So we have the form:
[tex](1.03469)^t[/tex]
With our APR simply being the base - 1
[tex]APR \approx 0.03469[/tex]
Multiply this by 100 to get it in percentage form:
[tex]APR \approx 3.469\%[/tex]

From inspection of the compound interest formula:
[tex]\implies b^t=\left[\left(1+\dfrac{r}{n}\right)^n\right]^t[/tex]
To find the annual percentage rate:
[tex]\implies APR=(b-1)\times 100[/tex]
Compounded annuallyGiven:
r = 3.425% = 0.03425n = 1Substitute the values into the formula for [tex]b^t[/tex]:
[tex]\implies b^t=\left[\left(1+\dfrac{0.03425}{1}\right)^1\right]^t[/tex]
[tex]\implies b^t=\left(1.03425\right)^t[/tex]
Therefore, the annual percentage rate is:
[tex]\implies APR=(1-1.03425) \times 100[/tex]
[tex]\implies APR=0.03425 \times 100[/tex]
[tex]\implies APR=3.425\%[/tex]
Compounded semi-annuallyGiven:
r = 3.425% = 0.03425n = 2Substitute the values into the formula for [tex]b^t[/tex]:
[tex]\implies b^t=\left[\left(1+\dfrac{0.03425}{2}\right)^2\right]^t[/tex]
[tex]\implies b^t=\left(1.03454326...\right)^t[/tex]
[tex]\implies b^t=\left(1.03454\right)^t[/tex]
Therefore, the annual percentage rate is:
[tex]\implies APR=(1-1.03454) \times 100[/tex]
[tex]\implies APR=0.03454 \times 100[/tex]
[tex]\implies APR=3.454\%[/tex]
Compounded quarterlyGiven:
r = 3.425% = 0.03425n = 4Substitute the values into the formula for [tex]b^t[/tex]:
[tex]\implies b^t=\left[\left(1+\dfrac{0.03425}{4}\right)^4\right]^t[/tex]
[tex]\implies b^t=\left(1.03469241...\right)^t[/tex]
[tex]\implies b^t=\left(1.03469\right)^t[/tex]
Therefore, the annual percentage rate is:
[tex]\implies APR=(1-1.03469) \times 100[/tex]
[tex]\implies APR=0.03469 \times 100[/tex]
[tex]\implies APR=3.469\%[/tex]
Compounded dailyGiven:
r = 3.425% = 0.03425n = 365Substitute the values into the formula for [tex]b^t[/tex]:
[tex]\implies b^t=\left[\left(1+\dfrac{0.03425}{365}\right)^{365}\right]^t[/tex]
[tex]\implies b^t=\left(1.03484162...\right)^t[/tex]
[tex]\implies b^t=\left(1.03484\right)^t[/tex]
Therefore, the annual percentage rate is:
[tex]\implies APR=(1-1.03484) \times 100[/tex]
[tex]\implies APR=0.03484 \times 100[/tex]
[tex]\implies APR=3.484\%[/tex]

First use appropriate properties of logarithms to rewrite f(x) and then find f’(x)
Answer:
f(x) = 6ln(8) -6ln(x)f'(x) = -6/xStep-by-step explanation:
You want to rewrite f(x) and differentiate it for f(x) = 6·ln(8/x).
Rules of logarithmsThe log of a ratio is the difference of logs:
ln(a/b) = ln(a) -ln(b)
ApplicationUsing this to rewrite f(x), we have ...
f(x) = 6ln(8/x) = 6(ln(8) -ln(x))
f(x) = 6·ln(8) -6·ln(x)
DerivativeThe derivative of the constant is zero, so ...
f'(x) = -6/x

The length of a rectangle is twice its width.
If the perimeter of the rectangle is 48 cm, find its length and width.
If the perimeter of the rectangle is 48 cm, its length and width is equal to 16 cm and 8 cm respectively.
How to calculate the perimeter of a rectangle?Mathematically, the perimeter of a rectangle can be calculated by using this equation;
P = 2(L + W)
Where:
P represents the perimeter of a rectangle.L represents the length of a rectangle.W represents the width of a rectangle.Since the length is twice the width, we have;
L = 2W
Substituting the given parameters into the perimeter formula, we have;
48 = 2(2W + W)
48 = 6W
W = 48/6
Width, W = 8 cm.
For the length of this rectangle, we have;

Which of the following is not a solution for x < 8?
O x = -3
OX= 7.95
Ox=9
OX= 4.3
Answer:
x=9
Step-by-step explanation:
x=9
To find out what is a solution for x<8 you have to plug in all the answer choices for x.
When you plug in -3, you get -3<8 and 8 is bigger than -3, so then that makes it a solution because -3 is less than 8 and when you plug it in it sets the equation right.
When you plug in 7.95, you get 7.95<8 and 8 is bigger than 7.95 by a few but it still is bigger so then it's a solution because 7.95 is less than 8 making it a solution.
When you plug in 4.3, you get 4.3<8 and 8 is bigger than 4.3 so then it's a solution because it sets the equation right.
When you plug in 9, you get 9<8 and that's not right because 8 isn't bigger than 9, setting this answer choice as a non-solution to the inequality.

The sold price of company x is 1000 more than the other. Therefore, find the value of each company's product sold price by framing a linear equation?
The value of each company's product sold price is given as follows:
Company x: $22,000,500.Company y: $21,999,500.How to obtain the values?The values of each company's product sold price is obtained using a system of equations, for which the variables are defined as follows:
Variable x: Company's x sold price.Variable y: Company's y sold price.The sold sum of both the two companies salaries are $44,000,000, hence:
x + y = 44000000.
The sold price of company x is 1000 more than the other, hence:
x = 1000 + y.
Then the sold price of company y can be found replacing the second equation into the first, as follows:
1000 + y + y = 44000000
2y = 44000000 - 1000
y = (44000000 - 1000)/2
y = $21,999,500.

The semicircle above has a radius of r inches, The distance between the chord and the diameter in terms of r is √5 r/3 inches.
What is chord of Circle ?A chord of a circle can be defined as a line segment connecting any two points on the circumference. It should be noted that the diameter is the longest chord of a circle which passes through the center of the circle.
To find the distance required one can use either the Pythagorean theorem or the trigonometric ratios. Let the semicircle have center O. The diameter AB has length 2r. Because chord CD is 2/3 of the length of the diameter,
CD=2/3(2r) = 4r/3
let the distance between diameter AB and chord CD be x inches. To find x draw a right triangle connecting center O, the midpoint, E of chord CD, and point C . Using Pythagorean theorem here,
r² = x² + (CD/2)²
=> r² = x² + (2r/3)²
=> r² = x² + 4r²/9
=> x² = r² - 4r²/9 = 5r²/9
=> x = √5 r/3
Hence, the distance between the chord and the diameter in terms of r is √5r/3..

Long division can be used to determine the absolute value of x[0], x[-1], and x[-2] when the roc is known. To do this, divide the roc (113) by the coefficient of the highest power in the polynomial (x2). Then, divide the remainder (3) by the coefficient of the next highest power (x), which gives x[-1] = 3. Finally, divide the remainder (8) by the coefficient of the lowest power (1), which gives x[-2] = 8.
To use long division to determine the values of x[0], x[-1], and x[-2], begin by dividing the roc (113) by the coefficient of the highest power in the polynomial (x2). This gives a result of 113/x2 = 10. This means that x[0] = 10. This number is then used as the divisor for the next step, which is to divide the remainder (3) by the coefficient of the next highest power (x). This gives a result of 3/x = 3, so x[-1] = 3. Finally, divide the remainder (8) by the coefficient of the lowest power (1), which gives 8/1 = 8, so x[-2] = 8. This process can be repeated to determine the values of x[n] for any polynomial.

The tanθ for the angle θ that lies in Quadrant III is √35
How to determine tanθ?Trigonometry simply means the branch of mathematics that is concerned with functions of angles as well as their applications to calculation. It also deals with the relationship between ratios and their angles.
Given: The angle θ lies in Quadrant III
cosθ= −1/6 (adjacent/hypotenuse)
adjacent = -1 and hypotenuse = 6
We can draw the position of the angle as shown in the image attached.
Using Pythagoras' theorem:
opposite = √6²-(-1)² = √35
tanθ = (-√35) / (-1) = √35 (tanθ = opposite/adjacent)
Note: opposite in Quadrant III is negative

2) If you wish to save up $220,000 using an annuity, what monthly payment is required into the
annuity if the annuity has an APR of 8.0% compounded annually and you wish to reach your
savings goal in 30 years?
Answer:
$936.91
Step-by-step explanation:
To find the monthly payment required to save up $220,000 using an annuity with an APR of 8.0% compounded annually over 30 years, we can use the following formula:
payment = (goal * rate) / (1 - (1 + rate) ^-n)
In this formula, "goal" is the savings goal, "rate" is the monthly interest rate, and "n" is the number of payments.
To find the monthly payment, we need to first convert the annual interest rate to a monthly rate by dividing it by 12:
rate = 8.0% / 12 = 0.0067
Next, we need to find the number of payments by multiplying the number of years by the number of payments per year:
n = 30 years * 12 payments/year = 360 payments
Substituting these values into the formula, we get:
payment = (goal * rate) / (1 - (1 + rate)^-n)
= (220,000 * 0.0067) / (1 - (1 + 0.0067)^-360)
= $936.91
The monthly payment required to save up $220,000 using an annuity with an APR of 8.0% compounded annually over 30 years is $936.91.
LetVbe the vector space of continuous functions defined on the interval[0,1]. Define an inner product onVby the following rule:⟨f,g⟩=∫01f(x)g(x)dx.Use the Gram-Schmidt orthonormalization procedure to produce an orthonormal basis for the subspace spanned by1,x,x2. Use the results to find the closest-point projection ofx3into this subspace.
The closest projection will have a value of -29/360.
we will follow these steps to use the Gram-Schmidt orthonormalization procedure for producing an orthonormal basis for the subspace spanned by 1, x, and x²,
Set u₁ = 1, a unit vector.
Set v₂ = x and u₂ = v₂ / ||v₂||.
Set v₃ = x² - (x², u₁)u₁ - (x², u₂)u₂, and u₃ = v₃ / ||v₃||.
Thus we get the orthonormal basis for the subspace spanned by 1, x, and x² to be {u₁, u₂, u₃}.
Now we will use the formula for the projection of a vector onto a subspace to find the closest-point projection of x³ into this subspace,
proj_subspace(x³) = (x³, u₁)u₁ + (x³, u₂)u₂ + (x³, u₃)u₃
The inner products will be calculated as follows:
(x³, u₁) = ∫x³ X 1 dx = 1/4
(x³, u₂) = ∫ x³ X x dx = 1/5
(x³, u₃) = ∫ x³ * (x² - (x², u₁)u₁ - (x², u₂)u₂) dx
Here all the integrals will have limits of 0 and 1.
Hence we get
= 1/9 - 1/4 X 1/2 - 1/5 X 1/3
= 1/9 - 1/8 - 1/15
= (40 - 45 - 24)/360
= -29/360
Thus, the projection of x³ onto the subspace spanned by 1, x, and x² is:
proj_subspace(x³) = 1/4 X u₁ + 1/5 X u₂ + (1/9 - 1/4 X 1/2 - 1/5 X 1/3) X u₃
This projection is the closest point in the subspace to x³, in the sense that the distance between x³ and proj_subspace(x³) is minimized.
