For an saving account in a bank, With the given value of the rate 'r' and the compounding period 'n' , The AER on the saving account is given by :

AER = [tex](1+\frac{r}{n})^{n} -1[/tex] .

The interest rate on a savings account or investment product with multiple compounding periods is known as the annual equivalent rate (AER). The next interest payment will be based on the marginally higher account amount, and AER is computed under the presumption that any interest paid is included in the balance of the principle payment.

The main benefit of AER is that it takes compounding effects into account, making it the real rate of interest.

Unfortunately, the AER is typically not mentioned when investors are comparing various investment possibilities. Investors are required to perform the calculations themselves.

n= compounding periods.

r= rate

The horizontal component of the force vector is 260 pounds, and the vertical component is 150 pounds. (Option B).

To find the horizontal and vertical components of the force vector, we can use trigonometry. The horizontal component is the force acting in the direction parallel to the ground (x-axis), and the vertical component is the force acting in the direction perpendicular to the ground (y-axis).

Given that the force is 300 pounds and makes a 30° angle with the ground, we can calculate the components as follows:

Horizontal component (F_horizontal) = Force * cos(angle)

Vertical component (F_vertical) = Force * sin(angle)

Inserting in the values:

Horizontal component (F_horizontal) = 300 pounds * cos(30°)

Vertical component (F_vertical) = 300 pounds * sin(30°)

Now, let's calculate:

Horizontal component (F_horizontal) = 300 pounds * 0.866 (rounded to 3 decimal places, cos(30°) ≈ 0.866)

F_horizontal ≈ 259.8 pounds

Vertical component (F_vertical) = 300 pounds * 0.5 (rounded to 3 decimal places, sin(30°) ≈ 0.5)

F_vertical ≈ 150 pounds

Therefore, the required components of the force vector are approximately 260 pounds and 150 pounds.

Answer:

To have 4 times as many apples as bananas, Amadou could have bought 4 apples for every 1 banana, or 8 apples for every 2 bananas, or 16 apples for every 4 bananas.

4 apples : 1 banana

8 apples : 2 bananas

16 apples : 4 bananas

We can use the fact that the total cost of the apples and bananas was $9 to determine the number of apples and bananas that Amadou bought. Since each apple costs $1, Amadou bought 9 apples if he bought no bananas, or 7 apples if he bought 2 bananas, or 5 apples if he bought 4 bananas.

9 apples : 0 bananas

7 apples : 2 bananas

5 apples : 4 bananas

Therefore, the possible combinations of apples and bananas that Amadou could have bought are 9 apples and 0 bananas, 7 apples and 2 bananas, or 5 apples and 4 bananas.

if the sum of two digits is divided by the sum of the digits, the number is  80.

Generally, Let the two digits of the number be x and y. The number can be written as 10x + y.

We are given that (x+y)/(x+y) = 6, which means that x + y = 6x + 6y.

Subtracting x + y from both sides, we get 5x = 5y. Therefore, x = y.

We are also given that the number is 9 greater than the number formed by reversing the digits, which means that 10x + y = 9 + 10y + x.

Combining like terms, we get 9x = 8y, or x = 8/9y.

Substituting this expression for x into the equation x = y, we get 8/9y = y, which means that y = 0.

Therefore, the number is 10x + y = 10 * (8/9y) + 0 = 80.

To calculate the amount of commission that Nancy Bell earned last month, we can use the following formula:

Commission = Sales * Commission Rate

In this case, the sales are $59,400 and the commission rate is 14%, so the commission is:

Commission = $59,400 * 14% = $8,356

To calculate Nancy's gross pay, we can add her salary to her commission:

Gross Pay = Salary + Commission

Gross Pay = $1,710 + $8,356 = $10,066

Therefore, Nancy earned $8,356 in commission and her gross pay was $10,066.

Answer: 890 downloads the high-quality version

Step-by-step explanation:

Let x be the number of downloads of the high-quality version

1420-x be the number of downloads of the standard version

So, we have the equation

4.5x + 2.7(1420-x) = 5436

4.5x + 3834 - 2.7x = 5436

1.8x + 3834 = 5436

Subtract 3834 on both sides

1.8x = 1602

x = 890

13) y= 3/5 x +2

14) y= x + 2

Step-by-step explanation:

To find the rate of change you use your slope formula which is y2-y1 over x2-x1.

You'd set your equation and you'd get 4-2 over 20-10. You solve and you get 2/10 and because it isn't one of the answer choices you have to simplify it. To simplify it you find the common number they both share and they both share 2 so you divide both by 2. 2 divided by 2 is 1 and 10 divide by 2 is 5. So then the rate of change or slope is 1/5.

The midrange for the data items in the given frequency distribution is 30.5.

Generally, To find the midrange for the data items in the given frequency distribution, we need to calculate the midpoint of each score range. The midpoint of a range is calculated by taking the average of the lower and upper bounds of the range.

For the first score range (29-30), the lower bound is 29 and the upper bound is 30, so the midpoint is (29 + 30) / 2 = 29.5.

For the second score range (30-31), the lower bound is 30 and the upper bound is 31, so the midpoint is (30 + 31) / 2 = 30.5.

Therefore, the midrange for the data items in the given frequency distribution is 30.5.

Here we have the following equation:

[tex]\frac{-15x + 10}{(5x - 2)^2} = \frac{A}{5x - 2} + \frac{B}{(5x - 2)^2}[/tex]

If we multiply and divide the first therm in the right side by (5x - 2) we will get:

The numerators must be equal, then we can write:

-15x + 10 = A*(5x - 2) + B

-15x + 10 = A*5x - 2A + B

Answer:

x=5, y=2 | Equations: 4x+y=22 (or see below) and 12x-5y=50

Step-by-step explanation:

Here's my attempt:

First Equation:

Because triangles ΔSTU and ΔXYZ are congruent, then we can say that:
m∠S = m∠X
m∠T = m∠Y
m∠U = m∠Z

We know that m∠X = 130°, and that m∠X = m∠S, so m∠S = 130°

We also know that the sum of angles in a triangle = 180°

We also know the rest of the angles in ΔSTU: 28° and (4x+y)°

So, we can say that ∠S + ∠T + ∠U = 130+28+4x+y = 180 (we can remove the degree sign)

Now, you can either enter this as it is or simplify it: ❗

130+28+4x+y=180

4x+y+158=180

4x+y=22

Second Equation:

We can do the same thing as for the first equation and get the angles of ΔXYZ:

∠X = 130, ∠Y = 8x-6y, ∠Z = 4x+y

Then, add them and set it to 180:

130+8x-6y+4x+y=180

Simplify:

12x-5y+130=180

12x-5y=50

To solve for x and y:

Now, we have to solve the systems.

Let's start with the first one:

4x+y=22

Isolate y:

y=22-4x (Equation 1)

Then, we plug it into the second equation:

12x-5y=50

12x-5(22-4x)=50

12x-110+20x=50

32x=160

x=5

So we got x, but to find y, we need to plug in x into Equation 1 (where we isolated y

y=22-4x

y=22-4(5)

y=22-20

y=2

We have both our x and y values

Answer:

Step-by-step explanation:

Angle EHG is a right angle, so it measures 90°.

The measures of angles EHF and FHG add to 90°.

m<EHF + m<FHG = 90°

m<FHG = 27°

m<EHF + 27° = 180°

m<EHF = 153°

Examining the triangles, the length of side QT is 2.5

This is a term used in geometry to mean that the respective sides of the triangles are proportional and the corresponding angles of the triangles are congruent

Hence assuming the corresponding angles of the triangle are congruent then the side should be in proportions

The solution is worked out using sides SQ and QR, then ST and TU

(12 + QT) / 18 = 12 / 6(QT)

let QT = x

(12 + x) / 18 = 12 / 6x

cross multiplying

72x + 6x² = 216

6x² + 72x - 216

x = 2.5 OR -14.4

Vertical angles are two angles that are opposite each other and share a common vertex. Adjacent angles are two angles that share a common side and vertex.

To find the measure of an unknown angle using these relationships, you can use the vertical angle theorem which states that if two angles are vertical, then they have equal measure. For example, if angle A and angle B are vertical angles, then angle A = angle B.

Example:

Given: Angle A = 40°

Find the measure of angle B

Solution:

Since angle A and angle B are vertical angles, then angle A = angle B

Therefore, the measure of angle B = 40°

An angle is created when two straight lines or rays intersect at the same point. The point where all points converge is known as an angle's vertex. The Latin word angulus, which meaning "corner," is where the term "angle" comes from.
