Answer:

The compound interest formula is A = P(1 + r/n)^(nt) where A is the final amount, P is the principal (initial deposit), r is the annual interest rate (expressed as a decimal), n is the number of times interest is compounded per year, and t is the number of years.

In this case, P = 2750, r = 0.035, n = 4 (because interest is compounded quarterly) and t = 7 (because we are trying to find the balance after 7 years).

So the formula becomes:

A = 2750(1 + 0.035/4)^(4*7)

By plugging the number into the formula we can find the final amount after 7 years

A = $3,974.23

So the amount of money in the account at the end of 7 years is $3,974.23, rounded to the nearest hundredth.

The TI-84 calculator is fairly powerful and can handle things like this, but it's not needed to be honest. Any calculator will do.

"csc" is shorthand for "cosecant". It's the reciprocal of sine.

csc = 1/sin

Recall that

sin = opposite/hypotenuse

which means

csc = 1/sin = hypotenuse/opposite

What we'll need are the hypotenuse and opposite sides. Plot the points (0,0) and (-20,21). Draw a segment between them. This forms the hypotenuse of the right triangle shown below. This triangle is in the quadrant Q2 in the upper left corner. The hypotenuse 29 is found using the pythagorean theorem a^2+b^2 = c^2.

Use a = 20 and b = 21 to find c = 29.

According to that diagram, we can then say:

csc = hypotenuse/opposite = 29/21

The exponential equation that models the function of Maureen's car is 26,525 (0.92)

a = 26,525 and b = 0.92

Exponential function is a type of function of the form: f(x) = a(b)^x. It is made up of  3 main parts

a = the starting value

b = the base function

x = the exponents

Considering the problem,

the starting = $26,525

the base = depreciation

the exponents = x

A year ago hence x = 1

$24,403 = $26,525(b)¹

b = 24,403 / 26,525

b = 0.92

hence we can say that a = 26,525 and b = 0.92

Answer:

m∠10 = 41°

Step-by-step explanation:

If ∠9 and ∠10 are complementary. Then ∠7 and ∠8 are complementary as well. Complementary angles meameansns they sum up to 90 degrees.

m∠7 + m∠8 = 90

m∠7 + 41 = 90

m∠7 = 90 - 41 = 49°

Given that m∠7 ≅ m∠9. So m∠9 = 49° and m∠10 = 41°.

If Mrs. Sharma spends 17/25 parts of her earnings on her children's education, then she is spending (17/25) x 100 = 68% of her earnings on her children's education.

If the number of children is the same, she spends 68%/number of children on her daughter education.

If she spends 68% of her earnings on her children's education, then she is saving 100 - 68 = 32% of her earnings.

So, she spends 68% on her daughter education and she saves 32% of her earning.

Answer:

In order to find the values of k and m in a parallelogram, you would need to have additional information such as the coordinates of the points that make up the parallelogram and the formulas or equations that relate k and m to these points.

Here is one way to find the values of k and m in a parallelogram:

Label the four vertices of the parallelogram as A, B, C, and D with the opposite sides parallel to each other.

Find the slope of the line segment AB by using the formula (y2-y1)/(x2-x1), where (x1, y1) and (x2, y2) are the coordinates of the two points.

Let the slope of AB be represented by k.

Find the slope of the line segment AD by using the same formula and let it be represented by m.

The values of k and m are now found.

Please note that, this method is only applicable if the Parallelogram is not degenerate i.e, it is not a rectangle or a line.

It is also important to keep in mind that different formulas or equations may be used depending on the specific context of the problem. It is also important to check that the slopes of opposite sides are equal.

Answer: the estimated maintenance cost of cars when the age of cars is 12 years is 16.5 ( in 100 birr)

Step-by-step explanation:

To obtain the regression equation for costs related to age of cars, we can use the method of least squares. This method involves finding the line of best fit that minimizes the sum of the squared differences between the predicted values and the actual values.

The equation for a linear regression line is:

y = a + bx

where a is the y-intercept and b is the slope of the line.

To find the slope of the line (b), we can use the formula:

b = (n(∑xy) - (∑x)(∑y)) / (n(∑x^2) - (∑x)^2)

To find the y-intercept (a), we can use the formula:

a = (∑y - b(∑x)) / n

Given the data provided, we can calculate the following values:

∑x = 142

∑y = 150

∑xy = 2430

∑x^2 = 10304

n = 8

By substituting these values into the formulas for b and a, we can find the slope and y-intercept of the line:

b = (8(2430) - 142(150)) / (8(10304) - 142^2) = 0.5

a = (150 - 0.5(142)) / 8 = 13.5

Therefore, the regression equation for the costs related to age of cars is:

y = 13.5 + 0.5x

To estimate the maintenance cost of cars when the age of cars is 12 years, we can substitute x = 12 into the equation and solve for y:

y = 13.5 + 0.5(12) = 16.5

So the estimated maintenance cost of cars when the age of cars is 12 years is 16.5 ( in 100 birr)

The percentage discount that Cyprian was allowed altogether was 8.21%.

The percentage discount is a portion of the sales price that reduces the amount the purchaser or customer pays for their purchase.

Percentages are ratios of a value or variable compared to another or the whole matter.

We express Percentages as the quotients of the division operations multiplied by 100.

In this situation, the overall percentage discount is worked out step by step as follows:

Discount on goods worth Sh. 800 = 11%

= Sh. 88 (Sh. 800 x 11%)

Discount on goods worth Sh. 17,000 = 8.6%

= Sh. 1,462

The total value of goods = Sh. 17,800 (Sh. 800 + Sh. 17,000)

Percentage discount = 8.21% (Sh. 1,462/Sh. 17,800 x 100)

Thus, overall, the total discount based on the full value of goods Cyprian bought was 8.21%.

The amount invested in the two different bank accounts which has a simple interest of $ 560 is $ 2000 and $ 4000 respectively

Simple interest is a method of calculating interest that ignores the impact of compounding. While interest frequently compounds throughout the course of a loan's set periods, simple interest does not. Simple interest is calculated by multiplying the principal amount by the interest rate, times the number of periods.

Simple Interest = ( Principal Amount x Rate x Time Period ) / 100

Given data ,

Let the simple interest be represented as SI

The value of SI = $ 560

Now , the total amount A = $ 6000

Let the first bank account be A

Let the second bank account be B

The amount invested in the bank account A be = P

The amount invested in the bank account B be = ( 6000 - P )

The rate of interest of bank account A = 8 %

The rate of interest of bank account B = 10 %

Now ,

The SI of bank account A = ( Principal Amount x Rate x Time Period ) / 100

Substituting the values in the equation , we get

The SI of bank account A = ( P x 8 x 1 ) / 100

The SI of bank account A = 8P/100

And ,

The SI of bank account A = ( Principal Amount x Rate x Time Period ) / 100

Substituting the values in the equation , we get

The SI of bank account A = [ ( 6000 - P ) x 10 x 1 ] / 100

The SI of bank account A = ( 60000 - 10P ) /100

And , the total SI = $ 560

So ,

8P/100 +  ( 60000 - 10P ) /100 = 560

Multiply by 100 on both sides of the equation , we get

8P + 60000 - 10P = 56000

On simplifying the equation , we get

-2P = -4000

Divide by -2 on both sides of the equation , we get

P = $ 4000

So , the amount invested in bank account A = $ 4000

And , the amount invested in bank account B = $ 2000

Hence , the amount invested is $ 4000 and $ 2000 respectively

Let the value of set A = { 1 , 2 , 3 , 4 }

Let the value of set C = { 1 , 2 , 3 , 6 , 8 }

Now , the equation of set is  ( A ∩ C )'

The value of ( A ∩ C )' = A' ∪ C'

Substituting the values in the equation , we get

A' = U - A

A' = { 1, 2, 3, 4, 5, 6, 7, 8 } - { 1 , 2 , 3 , 4 }

A' = { 5 , 6 , 7 , 8 }
