Find the amount (future value) of ordinary annuity $1000 a year for 10 years at 10%/year compounded annually.
a.
$15,500
b.
$15,937
c.
$16,456
d.
$16,845
The future value of ordinary annuity $1000 a year for 10 years at 10% year compounded annually is $15937.
The value of a sum of money that will be paid on a specified date in the future is known as its future value. Since each payment is made at the end of a period, the formula for the future value of an ordinary annuity refers to the value on a specified future date of a series of periodic payments.
Given,
R=$1000, n=10, i=10%=10/100=0.1
The formula to calculate the future value is
FV=R[(1+i)^n-1]/i
[tex]FV=R(\frac{(1+i)^{n} -1}{i})[/tex]
[tex]FV=1000(\frac{(1+0.1)^{10} -1}{0.1})[/tex]
[tex]FV=1000(\frac{(1.1)^{10} -1}{0.1})[/tex]
[tex]FV=1000(\frac{1.593742}{0.1})[/tex]
[tex]FV=1000\times15.9374[/tex]
[tex]FV=15937.4[/tex]
Future Value approximately equal to $15937.
Therefore, the future value of the ordinary annuity $100 a year for 10 years at 10% compounded annually is $15937, Option c is the correct answer.

The graph of a sinusoidal function has a minimum point at (0,2)(0,2)left parenthesis, 0, comma, 2, right parenthesis and then has a maximum point at (3\pi,6)(3π,6)left parenthesis, 3, pi, comma, 6, right parenthesis.
Write the formula of the function, where xxx is entered in radians.
The (0, 2) and (3•π, 6) minimum and maximum points on the graph of the sinusoidal function indicates that the function is as follows
[tex]y = 2\cdot sin\left(\dfrac{1}{3} \times \left(x - \dfrac{3\times \pi}{2} \right)\right) + 4[/tex]
What is a sinusoidal function?A sinusoidal function is a function based on the trigonometric function of sine.
The points on the graph of the sinusoidal function are;
Minimum point of the function; (3•π, 6)
Maximum point of the function; (0, 2)
The general form of the equation of a sinusoidal function is presented as follows;
The sinusoidal function equation is; y = a×sin(b×(x - h)) + k
The amplitude, a, is half the distance between the maximum and minimum points, therefore;
a = (6 - 2)÷2 = 2
a = 2
From the information in the question, when x = 0, y = 2
Plugging in the values of x = 0, y = 2in the equation, y = a×sin(b×(x - h)) + k, produces;
2 = 2×sin(b×(0 - h)) + k
The point (0, 2) is a minimum point, therefore; sin(b×(0 - h)) = -1
2 = 2×sin(b×(0 - h)) + k = 2×(-1) + k = -2 + k
k = 2 + 2 = 4
At the minimum point the value of sine is -1, which indicates that the value of the argument, (b•(0 - h)) = -π/2
Therefore; -b•h = -π/2
h = π/(2·b)
At the maximum point, (b×(x - h)) = π/2
Therefore; (b×(3×π - π/(2×b))) = π/2
b = 1/3
Therefore;
h = π/(2×b) = 3×π/2
y = 2×sin((1/3)×(x - 3×π/2)) + 4
The function is; y = 2×sin((1/3)×(x - 3×π/2)) + 4
The formula of the function for the graph is therefore; y = 2×sin((1/3)×(x - 3×π/2)) + 4

the question requests the cost of a "student ticket." Because we don't know, let's assume the student ticket price is "x" dollars.
Because we know from the question that "the price of an adult ticket is half the price of a student ticket plus $8.00," we can represent the adult ticket price as follows:
1/2 x + 8
If we also get "An adult ticket costs $15.00" from the question, we can write the equation as:
1/2 x + 8 = 15

In the given figure, the reflex angle DOB measures 3.5y and AOD measures Y. Find the measures of the non reflex DOB in degrees.
The measure of non reflex angle DOB in degrees is 140°
Calculating the measure of an angleFrom the given information, we are to determine the measure of the non reflex angle DOB
From the given information,
m reflex ∠ DOB = 3.5y
and
m ∠ AOD = y
First, we will determine the value of y
From Linear pair theorem, we can write that
3.5y + y = 180°
4.5y = 180°
y = 180°/4.5
y = 40°
Also,
y + m ∠ DOB = 180° (Linear pair theorem)
Thus,
40° + m ∠ DOB = 180°
m ∠ DOB = 180° - 40°
m ∠ DOB = 140°
Hence, the measure of ∠ DOB is 140°

Write an equation for the trend line shown on the scatter plot.
An equation for the trend line shown on the scatter plot is y = 5x + 15.
How to find an equation for the trend line?In order to determine a linear equation for the trend line (line of best fit) that models the data points described in the scatter plot above, we would have to calculate the slope of this line.
By critically observing the scatter plot, we can reasonably and logically deduce the following points through which the trend line passes through:
Points (x, y) = (2, 25)
Points (x, y) = (6, 45)
Mathematically, the slope of any straight line can be calculated by using this formula;
Slope, m = (Change in y-axis, Δy)/(Change in x-axis, Δx)
Slope, m = (y₂ - y₁)/(x₂ - x₁)
Slope, m = (45 - 25)/(6 - 2)
Slope, m = 20/4
Slope, m = 5.
At point (2, 25), a linear equation for the trend line can be calculated by using the point-slope form:
y - y₁ = m(x - x₁)
Where:
m represents the slope.x represents the length of trip (in days).y represents the weight (lbs).Substituting the given parameters into the formula, we have;
y - y₁ = m(x - x₁)
y - 25 = 5(x - 2)
y - 25 = 5x - 10
y = 5x - 10 + 25
y = 5x + 15.

The value of the unknown variable in the ordered pair is 8
How to determine the value of the unknown variable in the ordered pair?From the question, we have the following ordered pairs that can be used in our computation:
(r, 3), (5, 9)
Also, we have
m = 2
The meaning of the above notations are
Ordered pairs (x, y) = (r, 3), (5, 9)
Slope, m = 2
The slope of points is calculated using the following slope equation
Slope, m = (y₂ - y₁)/(x₂ - x₁)
Where
(x, y) = (r, 3), (5, 9) and m = 2
Substitute the known values in the above equation, so, we have the following representation
(9 - 3)/(r - 5) = 2
Evaluate the difference
This gives
6/(r - 5) = 2
Divide both sides by 2
So, we have
3/(r - 5) = 1
Cross multiply
r - 5 = 3
So, we have
r = 3 + 5
Evaluate the sum
r = 8
Hence, the value of r is 8

The vertex form of the quadratic equation is f(x) = -3(x - 2)² + 5. The coordinates of the vertex are (2, 5).
We are given a quadratic function. The equation of the quadratic function is f(x) = -3x² + 12x - 7. We need to convert the equation to vertex form. We can convert a quadratic equation to its standard vertex form by "completing the square" method. The calculations are done below.
f(x) = -3x² + 12x - 7
f(x) = -3(x² - 4x) - 7
f(x) = -3(x² - 4x + 2² - 2²) - 7
f(x) = -3(x² - 4x + 2²) - 7 + 3*2²

The perimeter of a rectangle i 202020 centimeter. The length i 666 centimeter. What i the area of the rectangle?
quare centimeter
The area of the rectangle is, 24 square centimeter.
What is area?
Area is a mathematical concept that expresses the size of a region on a planar or curved surface. The area of an open surface or the boundary of a three-dimensional object is referred to as the surface area, whereas the area of a plane region or plane area refers to the area of a form or planar lamina.
Let, the perimeter of the rectangle is 20 centimeter.
The length is 6 centimeter.
Suppose the width of the rectangle is y.
So,
Perimeter = 2(6) + 2(y)
20 = 12 + 2y
8 = 2y
y = 4
Hence, the width of the rectangle is 4 centimeter.
Since,
Area of rectangle = length x width
A = 6 x 4
A = 24
Therefore, the area of the rectangle is, 24 square centimeter.

log((4x)/(8))=log(x-5)
The given logarithmic equation solved for x is x = 10
Solving Logarithmic equationsFrom the question, we are to solve the given logarithmic equation.
The given logarithmic equation is
log((4x)/(8)) = log(x - 5)
To solve the given logarithmic equation, we will determine the value of the unknown variable.
The unknown variable in the equation is x.
From one of the rules of logarithm, we have that
If logₓY = logₓZ
Then,
Y = Z
Thus,
From log((4x)/(8)) = log(x - 5)
We can write that
(4x)/(8) = (x - 5)
Now, solve for x
(4x)/(8) = (x - 5)
Multiply both sides by 8
8 × (4x)/(8) = (x - 5) × 8
4x = 8x - 40
Subtract 8x from both sides of the equation
4x - 8x = 8x - 8x - 40
-4x = -40
Multiply both sides by -1
-1 × -4x = -1 × -40
4x =40
Divide both sides by 4
4x/4 = 40/4
x = 10
Hence, the solution of the equation is x = 10

remember, when multiplying exponents of the same base, we add the exponents : e.g.
a⁵ × a³ = a⁸
when we have exponents in exponents we multiply the exponents : e.g.
(a³)⁴ = a¹²
now, also remember the priorities of mathematical operations :
1. brackets
2. exponents
3. multiplications and divisions
4. additions and subtractions
now, let's look at our expression again :
3³ × (3⁴)^(0.5)
since we only want to simplify and not to calculate, we leave (3⁴) alone, because the only thing we could do would be to actually calculate 3⁴.
so,
(3⁴)^(0.5) = 3^(4×0.5) = 3²

3³ × 3² = 3^(3+2) = 3⁵
