Nathan invested $3,500 in an account paying an interest rate of 3. 5% compounded quarterly. Assuming no deposits or withdrawals are made, how much money, to the nearest hundred dollars, would be in the account after 19 years?.

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

f(x) = -3(x - 2)² - 7 + 12

f(x) = -3(x - 2)² + 5

The coordinates of the vertex are (2, 5).

The quotient for the expression is 4.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

The next term of the given geometric series is the fifth term which is; a₅ = 4

We are given the geometric series as;

1024, -256, 64, -16,.....

The formula to find the nth term of a geometric series is;

aₙ = ar^(n - 1)

where;

a is first term

r is common ratio

n is position of term

Thus, from the given series, we have that;

a = 1024

r = -256/1024

r = -1/4

Thus, the formula for the nth term of the series is;

aₙ = 1024(-¹/₄)^(n - 1)

Next term is the fifth term and so we have;

a₅ = 1024(-¹/₄)^(5 - 1)

a₅ = 1024(-¹/₄)^(4)

Step-by-step explanation:

Answer:

the answer i think it is 432

Step-by-step explanation:

so, it is

3³ × (3⁴)^(0.5) ?

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

and then,

3³ × 3² = 3^(3+2) = 3⁵

so, the simplified expression is 3⁵.

The given logarithmic equation solved for x is x = 10

From 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

Step-by-step explanation:

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.

The measure of non reflex angle DOB in degrees is 140°

From 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°

An equation for the trend line shown on the scatter plot is y = 5x + 15.

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:

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 (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]

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 value of the unknown variable in the ordered pair is 8

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
