A property is available for sale that could normally be financed with a fully amortizing $83,000 loan at a 10 percent rate with monthly payments over a 25-year term. Payments would be $754.22 per month. The builder is offering buyers a mortgage that reduces the payments by 50 percent for the first year and 25 percent for the second year. After the second year, regular monthly payments of $754.22 would be made for the remainder of the loan term.
The buyer were to opt for the builder's offer, the total payments over the life of the loan would be $248,110. This includes interest payments of $165,110. So, while the reduced payments may seem like a good deal in the short-term, buyers need to carefully consider the long-term implications before making a decision.
The builder's Mortgage offer seems attractive, as it significantly reduces the payments for the first two years. However, it's important to consider the long-term implications of this offer.
While the reduced payments may be helpful for buyers who are facing financial constraints in the short-term, they may end up paying more over the life of the loan.
Let's look at the numbers. With the builder's offer, the payments for the first year would be $377.11 per month, and $565.67 per month for the second year. This means that the total payments for the first two years would be $13,165.52. After that, the regular monthly payments of $754.22 would kick in, and the buyer would need to pay this amount for the remaining 23 years of the loan.
If the buyer were to opt for the fully amortizing loan with monthly payments of $754.22 for the entire 25-year term, the total payments over the life of the loan would be $226,266. This includes interest payments of $143,266.
On the other hand, if the buyer were to opt for the builder's offer, the total payments over the life of the loan would be $248,110. This includes interest payments of $165,110. So, while the reduced payments may seem like a good deal in the short-term, buyers need to carefully consider the long-term implications before making a decision.

From the calculation, we have the total area of the figure as shown to be 86 cm^2.
What is area of a triangle?The area of a triangle is the amount of space that is enclosed within the three sides of a triangle. It can be calculated using the formula:
A = 1/2 * b * h
where A is the area of the triangle, b is the length of the base of the triangle, and h is the height of the triangle, which is the perpendicular distance from the base to the opposite vertex.
We know that;
Tan 45 = h/10
h = 10 cm
Then;
Tan 30 = 10/10 + x
0.58 = 10/10 + x
0.58(10 + x) = 10
5.8 + 0.58x = 10
x = 7.2 cm
Thus;
The area of the first triangle = 1/2 * 10 * 10

1. The diagonal of the base of the box is shorter than the length of the wind chime. 2. The interior diagonal of the box shorter than the length of the wind chime. 3. The wind chime will not fit in the box.
What is diagonal?A diagonal is a line segment that connects two polygonal corners (vertexes), although it is not an edge (side). In other words, it connects any two polygonal vertices that are not neighboring. So, when we directly link any two vertices that are not connected by any sides, we may draw the diagonals in a polygon. A diagonal is a line that runs straight across the vertices of a polygon and joins its opposing corners. In other terms, a line segment connecting any two non-adjacent corners is a polygon's diagonal. Depending on how many sides a polygon has, distinct polygons may have a variable number of diagonals.
Given that the length of the wind chime is 16 inches thus,
1. diagonal of base of the box = √10²+8² = √164 = 12.8
Hence, the diagonal of the base of the box is shorter than the length of the wind chime.

At age 20, someone sets up an IRA (individual retirement account) with an APR of 6%. At the end of each month he deposits $50 in the account. How much will the IRA contain when he retires at age 65?
Compare that amount to the total deposits made over the time period.
After retirement the IRA will contain S
(Do not round until the final answer. Then round to the nearest cent as needed.)
The total deposits made over the time period is $
(Type a whole number.)
Answer:
To calculate the amount in the IRA at retirement, we can use the formula for the future value of an annuity:
S = PMT * (((1 + r)^n - 1) / r)
Where:
PMT = the monthly payment (in dollars)
r = the monthly interest rate (APR/12)
n = the number of months (45 years * 12 months/year)
Substituting the given values, we get:
PMT = $50
r = 0.06/12 = 0.005
n = 45 * 12 = 540
S = $50 * (((1 + 0.005)^540 - 1) / 0.005) = $204,055.57
So the IRA will contain $204,055.57 at retirement.
The total deposits made over the time period is:
Total deposits = 540 * $50 = $27,000
Therefore, the amount in the IRA at retirement ($204,055.57) is significantly higher than the total deposits made over the time period ($27,000). This demonstrates the power of compound interest over a long time horizon

How do you solve this?
The approximate diameter of the sphere is 29.3 cm, the correct option is C.
To find the approximate diameter of the sphere, we can use the formula for the volume of a sphere and solve for the diameter.
The following equation determines a sphere's volume:
V = [tex]\frac{4}{3} \pi r^{3}[/tex]
where r is the sphere's radius and V is its volume.
We are given the volume of the sphere as 3600 cubic centimeters. If we use this value as a substitute in the formula, we get:
3600 = [tex]\frac{4}{3} \pi r^{3}[/tex]
Multiplying both sides by [tex]\frac{3}{4}\pi[/tex], we get:
r³ = ([tex]\frac{3}{4}\pi[/tex]) × 3600
r³ = 8100
If you take the cube-root of both sides, you get:
r = [tex]8100^{1/3}[/tex]
r ≈ 14.6 cm
So, the radius of the sphere is approximately 14.6 cm.
The sphere's diameter is twice its radius. Therefore, the approximate diameter of the sphere is:
d = 2r
d= = 2 × 14.6
d ≈ 29.3 cm

(b) If you put $8350 in the ATM each day, what percent of the days in a month should you expect to run out of cash?
You can expect to run out of cash on approximately 39.45% of the days in a month when withdrawing $8,350 every day.
To determine the percentage of days in a month where you can expect to run out of cash, we'll need to consider the following terms: daily withdrawal, monthly cash usage, and average days in a month.
1. Daily withdrawal: This is the amount of money you withdraw from the ATM each day. In this case, you withdraw $8,350 every day.
2. Monthly cash usage: This is the total amount of money you will withdraw in a month. To calculate this, multiply the daily withdrawal by the number of days in a month. Since the average number of days in a month is approximately 30.42 (365 days in a year / 12 months), the monthly cash usage would be $8,350 x 30.42 ≈ $253,507.
3. Average days in a month: As mentioned earlier, this is approximately 30.42 days.
Now, we need to determine the number of days you would run out of cash. To do this, divide your monthly budget by the daily withdrawal amount. Let's assume you have a budget of $100,000:
Days without cash = $100,000 / $8,350 ≈ 11.98 days.
Since you can't have a fraction of a day, round it up to 12 days.
4. Calculate the percentage: To find the percentage of days you would run out of cash, divide the number of days without cash by the average number of days in a month and multiply by 100:
Percentage = (12 days / 30.42 days) x 100 ≈ 39.45%.
So, you can expect to run out of cash on approximately 39.45% of the days in a month when withdrawing $8,350 every day.

A group of students stand at the door of the school and asked every 10th student who they would vote for in the upcoming class elections and why?
This is an example of a survey or sampling technique called systematic sampling. The students are selecting every 10th student from the population (in this case, the population is the entire student body) to survey.
This technique can be useful when the population is too large to survey everyone or when a random sample is difficult to obtain. By using systematic sampling, the students can obtain a representative sample of the student body without having to survey every single student.
However, it's important to note that systematic sampling can introduce bias if there is a pattern or structure in the population that is related to the sampling interval. For example, if every 10th student is in a particular grade level or section of the school, this could skew the results of the survey. To mitigate this potential bias, researchers should ensure that the sampling interval is random and that they are not selecting every nth person based on any identifiable characteristics.

length of side AB is approximately 5.74 units when rounded to the nearest hundredth
how to find value of x?To find the value of x in triangle ABC,
Applying the law of sines in triangle ABC, we have:
sin(A)/AB = sin(B)/AC
where AB is the length of side AB, and sin(A) and sin(B) are the sines of angles A and B, respectively.
Substituting the given values, we get:
sin(36)/AB = sin(180-36- angle C)/7
simplifying the equation, we get:
AB = 7sin(36)/sin(C)
To find the angle C, we can use the fact that the sum of the angles in a triangle is 180 degrees:
angle C = 180 - angle A - angle B
Substituting the given values, we get:
angle C = 180 - 36 - 90 = 54 degrees
Substituting the values of sin(36) and sin(54) into the equation for AB, we get:
AB = 7sin(36)/sin(54) = 5.74 (rounded to the nearest hundredth)
Therefore, the length of side AB is approximately 5.74 units when rounded to the nearest hundredth.

A quadratic function has zeros at x=3 and x=15. Which of the following must be the equation of its axis of symmetry?
The equation of its axis of symmetry is x = 4.
What is axis of symmetry?
The axis of symmetry is a line that divides a symmetrical object or shape into two mirror-image halves. In mathematics, the axis of symmetry is often used in the context of graphs of equations, particularly quadratic equations
The axis of symmetry of a quadratic function is a vertical line that passes through the vertex of the parabola.
If a quadratic equation has zeros at x = 3 and x = 5, then its factored form is:
(x - 3)(x - 5) = 0
Expanding this expression, we get:
x^{2} - 8x + 15 = 0
This is the standard form of a quadratic equation: ax^{2} + bx + c = 0, where a = 1, b = -8, and c = 15.
To find the x-coordinate of the vertex of the parabola, we can use the formula:
x = -b/2a
Substituting the values of a and b, we get:
x = -(-8)/(2*1) = 4
Therefore, the axis of symmetry is a vertical line passing through x = 4. The equation of this line is simply:
x = 4

Please help me with this question.
The correct option is (b) i.e. area of rectangle is [tex]x^{3} y^{4}[/tex].
What is rectangle?
The internal angles of a rectangle, which has four sides, are all exactly 90 degrees. the two sides come together at a straight angle at each corner ,The rectangle differs from a square because its two opposite sides are of equal length.
Given : width of rectangle : xy
length of rectangle : [tex]x^{2} y^{3}[/tex]
we know that, area of rectangle = length × breadth
= x²y³ × xy
Now, adding power of terms which has same base.
we get, [tex]x^{3} y^{4}[/tex]
so, the correct option is (b).

Binaya has fixed a water tank in the shape of cylinder surmounted by a hemisphere on the roof of his house. The tank has its internal radius 90 cm and total height 3.8 m.
1) Find the cost of filling the tank with water at the rate of 20 paisa per litre.
Answer:
To find the cost of filling Binaya's water tank, we need to calculate the volume of the tank first. The tank is in the shape of a cylinder surmounted by a hemisphere, so we can find the volume by calculating the volumes of the cylinder and hemisphere separately and adding them together.
The formula for the volume of a cylinder is V_cyl = πr^2h, where r is the radius and h is the height.
Given that the internal radius of the tank is 90 cm and the total height is 3.8 m, we convert the height to cm to match the radius unit and get 380 cm in height.
So, the volume of the cylinder part of the tank will be V_cyl = π(90)^2(380) = 9147600 cm^3.
The formula for the volume of a hemisphere is V_hem = (2/3)πr^3, where r is the radius of the hemisphere. By halving the internal radius of the cylinder, we get the radius of the hemisphere as 45 cm.
So, the volume of the hemisphere part of the tank will be V_hem = (2/3)π(45)^3 = 95325π cm^3.
The total volume of the tank will be the sum of the volumes of the cylinder and hemisphere:
V_total = V_cyl + V_hem = 9147600 + 95325π = 9457589.25 cm^3.
To convert this volume to litres, we divide by 1000:
V_total_l = 9457.59 l.
The cost of filling the tank with water at the rate of 20 paisa per litre will be:
Cost = 9457.59 x 0.20 = 1891.52 paisa = 18.92 rupees (rounded to two decimal places).
Therefore, it will cost Binaya 18.92 rupees to fill his water tank with water at the given rate.
Triangle DEF with D(-4, 6), E(2,6),
F(0,8): k = 1/2
Triangle DEF as shown ion figure D(-4, 6), E(2,6), F(0,8) translate by a factor of 1/2, So the new vertex are: D' (-2, 3), E' (1, 3), F' (0, 4)
Describe the term triangle?Triangle is commonly represented by a graph in which the three points are labeled as A, B, and C, and the three line segments are labeled as AB, AC, and BC. The graph of a triangle typically looks like below figure.
The new coordinates of each vertex of the triangle after scaling by 1/2.
For vertex D:
x-coordinate = -4, y-coordinate = 6
New x-coordinate = (1/2) × (-4) = -2
New y-coordinate = (1/2) × 6 = 3
So the new coordinates for D' are (-2, 3)
For vertex E:
E (2, 6) ⇒ 1/2 × (2, 6) ⇒ (1, 3)
So the new coordinates for E' are (1, 3)
For vertex F:
F (0, 8) ⇒ 1/2 × (0, 8) ⇒ (0, 4)
So the new coordinates for F' are (0, 4)
D(-4, 6), E(2,6), F(0,8) ⇒ D' (-2, 3), E' (1, 3), F' (0, 4)
Finally, plot the new points on the same coordinate plane and connect them to form the new triangle. You should see that the new triangle is a smaller version of the original triangle, with all sides and angles scaled down by a factor of 1/2.
