From the statement of the problem, we know the following data of the mortgage:
• t = time = 30 years,
,• P = principal = $100,000,
,• r = interest rate in decimal = 7/100 = 0.07.
The monthly payments are given by the following formula:
\(m=\frac{P\cdot\frac{r}{12}}{1-(1+\frac{r}{12})^{-t\cdot12}}\text{.}\)Replacing the data of the problem, we find that the monthly payments will be:
\(m=\frac{100,000\cdot\frac{0.07}{12}}{1-(1+\frac{0.07}{12})^{-30\cdot12}}\cong665.302.\)dollars.
The money that Aaron will pay in a year is 12 times the value of the monthly payment:
total of a year = 12 * $665.302 ≅ $7983.63.
Answer
Aaron will pay $7983.63 in a year.

What is the remainder when 287 is divided by 5?
Answer:
2
Step-by-step explanation:
Any multiple of 5 ends in 0 or 5.
To find the remainder when a number is divided by 5, we can find the highest number less than or equal to the given number that ends in 0 or 5, then subtract that number from the given number.
In this case, the highest number that ends in a 0 or 5 that is less than or equal to the given number is 285.
When we subtract that from the given number, 287, we get:
287 - 285 = 2

How to Use the Venn diagram to determine each set and the number of elements in each set?A Venn diagram is a pictorial representation used to visualize the relationships between different sets of objects or concepts.
a.) U is the universal set. This implies it contains all the elements in the set. Thus:
U = {1, 2, 3, 4, 5, 6, 7, 8, 9, 11, 12}
b.) A is all element (number) is set A (circle A). Thus:
A = {1, 3, 4, 5, 6, 8}
c.) B is all element is set B (circle B). Thus:
B = {4, 5, 6, 7, 9, 11}
d.) C is all element is set C (circle C). Thus:
C = {6, 8, 9, 12}
e.) A ∪ B is all element is sets A and B (circles A and B). Thus:
A ∪ B = {1, 3, 4, 5, 6, 7, 8, 9, 11}
f.) A ∩ B is all element is sets A and B (circles A and B) have in common. Thus:

What is the length of CD?
Answer:
CD = 15
Step-by-step explanation:
Pre-SolvingWe are given two quadrilaterals: CDEF and GIJH.
We know that CD = 3x - 6, and GI = x + 8.
We want to find the length of CD.
SolvingFinding xNotice how CD and GI both have one tick mark on them.
This indicates that these two are congruent, meaning that they have the same length.
Because of that, CD = GI.
If we substitute 3x - 6 for CD and x + 8 for GI, we get:
3x - 6 = x + 8
Now, we can solve this like a regular equation.
Add 6 to both sides.
3x - 6 = x + 8
+6 +6
_________________
3x = x + 14
Subtract x from both sides.
3x = x + 14
-x -x
_____________-
2x = 14
Divide both sides by 2.
2x = 14
÷2 ÷2
____________
x = 7
Finding the length of CDWe found the value of x.
Now, substitute 7 as x in 3x-6 (the length of CD).
CD = 3x - 6 = 3(7) - 6 = 21 - 6 = 15
Therefore, CD = 15.

Mr. Bauer Placed the letters in the word basketball into a bag what is the probability of choosing a B not replacing it and then choosing a vowel
Using it's concept, it is found that there is a 0.0333 = 3.33% probability of choosing a B not replacing it and then choosing a vowel.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
The word basketball has 10 letters.
b is one of them, hence P(A) = 1/10 = 0.1.Then, of the 9 letters, 3 will be vowels, hence P(B|A) = 3/9 = 1/3 = 0.3333.Thus, the probability of choosing a B not replacing it and then choosing a vowel is given by:
\(P(A \cap B) = P(A)P(B|A) = 0.1 \times 0.3333 = 0.0333\)

Karen obtains a loan for home renovations from a bank that charges simple interest at an annual rate of 3.6%. Her loan is for $14,300 for 99 days. Assume each day is 1365 of a year.
After 99 days, Karen is required to pay $14,436.63 in full, plus $139.63 in interest.
What is simple interest?
Simple interest is calculated based on a loan's principal or the initial deposit into a savings account. Simple interest doesn't compound, therefore a creditor will only charge interest on the principal sum, and a borrower will never be required to pay further interest on the interest that has already accrued.
Given, Karen obtains a loan for home renovations from a bank that charges simple interest at an annual rate of 3.6%. Her loan is for $14,300 for 99 days.
From the formula of simple interest(SI) :
SI = P * R * T / 100
Where p = principal amount
r = rate of interest
T = time
In our case
p = 14300
r = 3.6
time = 99/365
Simple interest = (14300* 3.6 * 99) / 36500
Simple interest = (143 * 3.6 * 99) / 365
Simple interest = 139.63
The total amount she has to pay = principal amount + SI
The total amount she has to pay = 14300 + 136.63
The total amount she has to pay = 14,436.63
therefore, Karen has to pay $139.63 interest and $14,436.63 Total amount after 99 days.

A plane flying with a constant speed of 360 km/h passes over a ground radar station at an altitude of 1 km and climbs at an angle of 30°. At what rate (in km/h) is the distance from the plane to the radar station increasing a minute later? (Round your answer to the nearest whole number.)
The rate (in km/h) at which the distance from the plane to the radar station is increasing a minute later is 0 km/h (rounded to the nearest whole number).
To solve this problem, we can use the concepts of trigonometry and related rates.
Let's denote the distance from the plane to the radar station as D(t), where t represents time. We want to find the rate at which D is changing with respect to time (dD/dt) one minute later.
Given:
The plane is flying with a constant speed of 360 km/h.
The plane passes over the radar station at an altitude of 1 km.
The plane is climbing at an angle of 30°.
We can visualize the situation as a right triangle, with the ground radar station at one vertex, the plane at another vertex, and the distance between them (D) as the hypotenuse. The altitude of the plane forms a vertical side, and the horizontal distance between the plane and the radar station forms the other side.
We can use the trigonometric relationship of sine to relate the altitude, angle, and hypotenuse:
sin(30°) = 1/D.
To find dD/dt, we can differentiate both sides of this equation with respect to time:
cos(30°) * d(30°)/dt = -1/D^2 * dD/dt.
Since the plane is flying with a constant speed, the rate of change of the angle (d(30°)/dt) is zero. Thus, the equation simplifies to:
cos(30°) * 0 = -1/D^2 * dD/dt.
We can substitute the known values:
cos(30°) = √3/2,
D = 1 km.
Therefore, we have:
√3/2 * 0 = -1/(1^2) * dD/dt.
Simplifying further:
0 = -1 * dD/dt.
This implies that the rate at which the distance from the plane to the radar station is changing is zero. In other words, the distance remains constant.

As per the given graph of a random function,
The value of f(x) decreasing when x is increasing is the interval on which we can say that function is decreasing.
If we look at the extreme left of the graph and come towards the right then the curve is going downward till x = -5.
Therefore, in interval (-∞, -5] function is decreasing.
The function is again going down in intervals [-2,2].
Therefore in inteval (-∞, -5] ∪ [-2, 2] the function is decreasing.
