Answer:
To calculate the amount you would need to invest in a money market account to have $5,000 at the end of 3 years, we can use the formula for future value of an investment:
FV = PV(1+r)^n
where FV is the future value of the investment, PV is the present value of the investment, r is the interest rate (expressed as a decimal), and n is the number of compounding periods.
In this case,
FV = $5,000 (future value)
r = 5% (APR) = 0.05 (as a decimal)
n = 3 years * 12 (months) = 36
So we can use the formula:
PV = FV / (1 + r)^n
PV = $5,000 / (1 + 0.05)^36
PV ≈ $3,716.76
So you would need to invest $3,716.76 in the money market account to have $5,000 in the account at the end of 3 years.
In △ABC, the length of median BM is half the length of side AB and ∠ABM measures 40°. Find m∠ABC.
Answer:
m∠ABC = 180.
Step-by-step explanation:
In a triangle, the median to the side opposite the largest angle bisects that angle.
Since BM is a median, it bisects ∠C, the angle opposite side AB.
Let's call the angle opposite side AB angle x, so x/2 = 40.
Therefore, x = 80
Since a triangle has 180 degree, then if we add all the angles in the triangle we get:
m∠ABC = m∠BAC + m∠BCA + m∠CAB = x + (180-x) + (180-x) =180
So m∠ABC = 180

Multiply the previous term by 3 and subtract 4 The second term of the sequence is 5. Find the difference between the first and fourth terms of the sequence.
Answer:
72
Step-by-step explanation:
Given that the second term of the sequence is 5, and that we are to multiply the previous term by 3 and subtract 4, we can use that as a recursive formula to find the other terms of the sequence.
The first term of the sequence is:
5*3-4 = 11
The third term of the sequence is:
53-4=11
113-4=29
The fourth term of the sequence is:
53-4=11
113-4=29
29*3-4=83
The difference between the first and fourth terms of the sequence is:
83-11 = 72
So the difference between the first and fourth terms of the sequence is 72.

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°.

7Mr's sharma spends 17/25 parts of her earning of her children education. how many childrene percent does she spends on her daughter education How many percent does she save.
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.
Cyprian was allowed a discount of 11% for goods at sh 800 and a discount of 8.6% for worth 17000.What percentage discount was he allowed altogether
The percentage discount that Cyprian was allowed altogether was 8.21%.
What is the percentage discount?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%.

Find the values of k and m in the parallelogram?
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.

Maureen bought a new car worth $26,525 one year ago. She knows that her car's value will depreciate each year. She uses an online calculator to find that her car is worth $24,403 today. Write an exponential equation in the form y = a(b) that can model the value, y, of Maureen's car x years after purchase. Use whole numbers, decimals, or simplified fractions for the values of a and b.
The exponential equation that models the function of Maureen's car is 26,525 (0.92)
a = 26,525 and b = 0.92
What is an exponential function?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: 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)

How do you do this math problem involving csc? Can you do it on a ti-84 calculator?
Explanation:
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

$2750 is invested at an interest rate of 3.5% APR compounded quarterly. Determine the amount after 7 years. Round your answer to the nearest hundredth.
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.
