An ordinary annuity that earns 7.5% compounded monthly has a current balance of $500000. The owner of the account is about to retire
and has to decide how much to withdraw from the account each month.
Find the number of withdrawals under each of the following options:
(a) $5000 monthly (b) $4000 monthly (c) $3000 monthly
Answers
PV = PMT x [1 - (1 + r/n)^(-nt)] / (r/n)
where PV is the present value (current balance), PMT is the withdrawal amount, r is the annual interest rate (7.5%), n is the number of times the interest is compounded per year (12 for monthly compounding), and t is the number of years.
(a) For PMT = $5000:
500000 = 5000 x [1 - (1 + 0.075/12)^(-12t)] / (0.075/12)
Simplifying and solving for t, we get:
t = 20.31 years
Therefore, the owner can withdraw $5000 per month for 20.31 years.
(b) For PMT = $4000:
500000 = 4000 x [1 - (1 + 0.075/12)^(-12t)] / (0.075/12)
Simplifying and solving for t, we get:
t = 24.85 years
Therefore, the owner can withdraw $4000 per month for 24.85 years.
(c) For PMT = $3000:
500000 = 3000 x [1 - (1 + 0.075/12)^(-12t)] / (0.075/12)
Simplifying and solving for t, we get:
t = 32.77 years
Therefore, the owner can withdraw $3000 per month for 32.77 years.
Note: These calculations assume that the interest rate and the monthly withdrawal amount remain constant over the entire period. In reality, the interest rate may fluctuate and the withdrawal amount may need to be adjusted over time to account for inflation and other factors.

Given a triangle with a = 19, A = 43°, and B = 26°, what is the length of c? Round to the nearest tenth.
C. 27
a. 26
d. 28
b. 25
Please select the best answer from the choices provided
Answers
The best answer from the given choices is b. 25.
To find the length of side c in the triangle, we can use the Law of Sines, which states that the ratio of the length of a side to the sine of its opposite angle is constant for all sides and angles in a triangle.
Using the Law of Sines, we can write:
c/sin(C) = a/sin(A)
Substituting the given values:
c/sin(43°) = 19/sin(26°)
Now, we can solve for c by rearranging the equation:
c = (19 * sin(43°)) / sin(26°)
Using a calculator, we find:
c ≈ 25.01
Rounded to the nearest tenth, the length of side c is approximately 25.0.
Therefore, the best answer from the given choices is b. 25.

12) (2, 3) over the x - axis becomes, (2, -3).
13) (7, -2) over the y - axis becomes, (-7, -2).
14) (4, 5) 90° about the origin becomes, (-5, 4).
15) (-3, -2) 270° about the origin becomes, (-2, 3).
16) (17, -23) over the line y = x becomes, (-23, 17).
What is transformation of points?
The reflection is the type of alteration that takes place when each point in the shape is reflected over a line. The picture is on the opposite side of the line from the pre-image when the points are reflected across a line, but it is still at the same distance from the line as the pre-image. The reflection of each point (p, q) onto an image point (q, p).
12) Reflect (2, 3) over the x axis:
Since, the x-coordinate of a point that is reflected across the x-axis stays constant, but the y-coordinate is assumed to be the additive inverse.
The x-axis' reflection of point (x, y) is (x, -y).
So, (2, 3) becomes, (2, -3).
13) Reflect (7, -2) over the y axis:
Since, the y-coordinate of a point that is reflected across the y-axis stays constant, but the x-coordinate is assumed to be the additive inverse.
So, (7, -2) becomes, (-7, -2).
14) Rotate (4, 5) 90° about the origin:
(x, y) → (-y, x) is the formula for a 90° rotation about the origin.
So, (4, 5) becomes, (-5, 4).
15) Rotate (-3, -2) 270° about the origin:
(x, y) → (y, -x) is the formula for a 270° rotation of the origin.
So, (-3, -2) becomes, (-2, 3).
16) Reflect (17, -23) over the line y=x.
The angle at which the point (x, y) is reflected across the line y = x is (y, x).
So, (17, -23) becomes, (-23, 17).

Solve the following system of inequalities graphically on the set of axes below. State the coordinates of a point in the solution set
yy<-1/2x-4
Answers
For the inequalities y > 3x - 5 and y < -x - 1 the points of solution set is (1,-2).
What is an inequality?
In Algebra, an inequality is a mathematical statement that uses the inequality symbol to illustrate the relationship between two expressions. An inequality symbol has non-equal expressions on both sides. It indicates that the phrase on the left should be bigger or smaller than the expression on the right, or vice versa.
The given inequalities are -
y > 3x - 5
y < -x - 1
Write both the inequalities in equation form -
y = 3x - 5 ..... (1)
y = -x - 1 ....... (2)
Substitute the value of y in equation (1) -
y = 3x - 5
-x - 1 = 3x - 5
-x - 3x = -5 + 1
-4x = -4
x = 1
Substitute the value of x in equation (1) -
y = 3x - 5
y = 3(1) - 5
y = -2
Therefore, the graphs of inequalities intersect at (1,-2).

Find the volume of the composite. The solid below is a square prism with a cylinder
cut out of it. Round to the nearest whole centimeter.
Answers
Answer:
17,242 cm³
Step-by-step explanation:
Step 1:
Volume of square prism = (area of base) * height
Volume of square prism = (25 * 30) * 25
Volume of square prism = 750 * 25
Volume of square prism = 18,750 cm³
Step 2:
Volume of cylinder = (area of base) * height
Volume of cylinder = (π * (8/2)²) * 30
Volume of cylinder = 16π * 30
Volume of cylinder = 480π
Volume of cylinder ≈ 1,508 cm³
Step 3:
Volume of composite = (Volume of square prism) − (Volume of cylinder)
Volume of composite = 18,750 cm³ − 1,508 cm³
Volume of composite = 17,242 cm³

One batch of pink paint uses 2 cups of red paint and 7 cups of white paint. 1 Mai made a large amount of pink paint using 14 cups of red paint. How many cups of white paint are used per cup of red paint? *
Answers
From the information given,
One batch of pink paint is made from 2 cups of red paint and 7 cups of white paint.
This means that the ratio of red paint to white paint in 1 batch of pink paint is 2:7
By reducing to the lowest term, it becomes 1:3.5
This means that 1.5 cups of red paint is used with 3.5 cups of white paint.
This ratio is constant.
Let x represent the number of cups of white paint used. Given that he made a large amount of pink paint by using 14 cups of red paint, it means that the number of cups of white would be
1/3.5 = 14/x
By cross multiplying, it becomes
x = 3.5 * 14
x = 49 cups
49 cups of white paint would be used with 14 cups of red paint
3.5 cups of white paint is used per cup of red paint

What is 88 2/4 rounded to the nearest whole number
Answers
The value of the mixed fraction 88²/₄ rounded to the nearest whole number is 89.
What are mixed fractions?A mixed fraction is one that is represented by both its quotient and remainder. A mixed fraction is, for instance, 2¹/₃, where 2 is the quotient and 1 is the remainder
To round 88²/₄ to the nearest whole number, we look at the fraction 2/4, which simplifies to 1/2.
If the numerator of the fraction is less than 1/2, we round down to the nearest whole number. If the numerator is greater than or equal to 1/2, we round up to the nearest whole number.
In this case, the numerator is 2, which is greater than 1/2. Therefore, we round up to the nearest whole number.

0.92 * 10²
How to use Laws of Exponents?The expression is given as:
6.89 * 10⁻⁴/(7.5 * 10⁻⁶) = 0.92 * 10¹
The steps that Maggie followed are:
Step 1: Rewrite the given expression:
6.89 * 10⁻⁴/(7.5 * 10⁻⁶) = 0.92 * 10¹
Step 2: Divide the coefficients:
The coefficient of the numerator (6.89) is divided by the coefficient of the denominator (7.5) to get:
6.89 / 7.5 = 0.9186667.
Step 3: Divide the powers of 10:
This is done by subtracting the exponent of the denominator 10⁻⁶ from the exponent of the numerator 10⁻⁴ to get: 10²
Step 4: Combine the results:
This gives:
0.9186667 * 10²
Step 5: Simplify the coefficient:
She rounded the coefficient (0.9186667) to two decimal places, resulting in 0.92.

How to evaluate vector?A physical quantity that has both directions and magnitude is referred to as a vector quantity.
A lowercase letter with a "hat" circumflex, such as "û," is used to denote a vector with a magnitude equal to one. This type of vector is known as a unit vector.
To evaluate u + v - 4u, we first need to find the vector 4u, which is obtained by multiplying the vector u by the scalar 4:
4u = 4(5,-2) = (20,-8)
Now, we can add u and v, and subtract 4u from the result:
u + v - 4u = (5,-2) + (-5,7) - (20,-8)
