Dante deposited $5,000 into an account with an annual interest rate of
3.5%. He plans to deposit an additional $200 each year, just after the
interest is compounded. What will his balance be after 16 years? (round to
the penny)
Dante deposited $5,000 into an account with an annual interest rate of
3.5%. He plans to deposit an additional $200 each year, just after the
interest is compounded. His balance will be $9,838.44 after 16 years.
What do you mean by annual interest rate?It displays the actual percentage rate of interest owed on any outstanding debts, including credit card debt and loans.
Because it takes compounding effects into account, the effective annual interest rate is the real interest rate on an investment or loan. The rate increases as the compounding periods get more frequent. Advertisements for loans or savings accounts may include both the nominal interest rate and the effective yearly interest rate. The rate that should be used to compare loan and investment rates of return is the effective annual interest rate.
We can substitute the known values into the formula and calculate the final balance:
A = $5,000 (1 + 0.035)¹⁶
We can calculate the final balance by using a calculator, or we can use the formula of compound interest:
A = P(1 + r/n)ˣ
where, A= Amount
P= Principle($5,000 )
x= Time(16 years)
n= Rate(3.5%)
A = $5,000 (1 + 0.035/1)¹⁶
Now we can add the $200 deposit each year for 16 years:
A = $5,000 (1 + 0.035)¹⁶ + $200 × 16
A = $9,838.44
Dante's balance will be $9,838

Ray AT bisects MAR. If m MAT = (6x - 4) and m RAT = (2x + 8), what is is the m MAR
Answer:
∠MAR = 28
Step-by-step explanation:
Given angle MAR bisected by ray AT to form angle MAT = (6x-4) and RAT = (2x+8), you want to know the measure of MAR.
Angle bisectorAn angle bisector divides an angle into two congruent parts:
∠MAT = ∠RAT
6x -4 = 2x +8
4x = 12 . . . . . . . . add 4-2x
x = 3 . . . . . . . divide by 4
Then the measure of one of the halves is ...
∠RAT = 2x +8 = 2·3 +8 = 14
So, the measure of the whole is ...
∠MAR = 2·14
∠MAR = 28
An airline run 156 domestic
flights and 34 international flights
each day from a particular
airport. A passenger states that
the ratio is 39 to 9. Is the
passenger correct, why or why
not?
Answer:
No
Step-by-step explanation:
For the passenger to be correct, the two ratios should equal each other.
[tex]\frac{156}{34}[/tex] = [tex]\frac{39}{9}[/tex] Multiply both sides by 34 and 9
[tex]\frac{(34)(9)}{1}[/tex] x [tex]\frac{156}{34}[/tex] = [tex]\frac{(34)(9)}{1}[/tex] x [tex]\frac{39}{9}[/tex] On the left side of the equation, the 34's cancel each other out. On the right side of the equation, the 9's cancel out. That leaves us with:
(9)(156) = (340)(39)
1404 = 13260
These numbers do not equal each other so the ratios are not equal.

The average rate of change of the given function is 20.
What is the average rate of change of the function?It quantifies how much the function changed per unit on average throughout that time interval. The slope of the straight line connecting the interval's ends on the function's graph is used to calculate it.
The average rate of change of a function f(x) over the interval [a,b] is given by the formula:
(f(b) - f(a)) / (b - a)
So, for the function f(x) = x² + 2 as x changes from 5 to 15, we can plug in the values to find the average rate of change:
(f(15) - f(5)) / (15 - 5) = (15² + 2 - 5² - 2) / (15 - 5) = (225 - 25) / 10 = 200 / 10 = 20

For example, 5, -3, and 0 are all integers.A mixed number is a combination of an integer and a fraction, such as 3 ½.A proper fraction is a fraction where the numerator (the number on top) is less than the denominator (the number on the bottom). For example, 3/4 is a proper fraction because 3 is less than 4. Improper fractions, on the other hand, have a numerator that is greater than the denominator, such as 7/4.In mathematics, integers are used to represent whole numbers and countable objects, while fractions are used to represent parts of a whole. Mixed numbers are a combination of both, used to represent a value that is between two integers. For example, if you were cooking a recipe that called for two and a half cups of flour, you would use a mixed number to represent this value.Proper fractions are useful for representing ratios or for dividing a whole into equal parts. For example, when dividing a cake into four equal parts, each part would be represented by a proper fraction, such as 1/4 or 2/4.Integers, mixed numbers, and proper fractions are all useful for representing different kinds of values and for performing calculations in mathematics.To learn more about mixed number refer to:

Two lines m annd l are perpendicular to lines pand n respectively. If n amd p intersect , proove l and m also intersect .
Answer:
See below
Step-by-step explanation:
Since lines n and p intersect, they must have different slopes. Lets say they have slopes 2 and 4, as an example. They will intersect. Lines m and l are perpendicular to n and p, so their slopes will be the negative inverse of 2 and 4. That gives them slopes of -(1/2) and -(1/4). These slopes are different, so they will intersect.
The attached graph illustrates this intersection with lines having the above slopes. Lines m and l intersect at (-1,1) in this example. Lines m and l also intersect, off the graph at the top left.

For option B, the interest amount would be:
Interest = $12,000 x 0.045 x (60/12) = $3,000
For option C, the interest amount would be:
Interest = $12,000 x 0.0375 x (66/12) = $2,970
For option D, the interest amount would be:
Interest = $12,000 x 0.04 x (72/12) = $3,840
As we can see the lowest interest amount is option C which is $2,970. Thus Ciara will pay the least interest if she chooses option C.

Answer:
Image 1 answer → not a polygon
Image 2 answer → n = 49 degrees
Image 3 answer → Square
Step-by-step explanation:
Image 1 explanation: Circles and ovals aren't polygons because their area and perimeter are calculated differently. So the answer is not a polygon.
Image 2 explanation: All complementary angles add up to 90 degrees, so 131 and 139 are incorrect. 41 and 49 add up to 90 degrees, which makes 49 degrees your answer.
Image 3 explanation: All options listed are quadrilaterals, but a square is the only shape that has 4 congruent sides and angles. Therefore, a square is a shape that possesses all the characteristics listed.
Have a great day! :)
