If the area of the rectangle is 324 square feet, the dimensions of the rectangle are length 9 feet and width 36 feet.

A rectangle with an area of 324 square feet and a length that is 4 times the width can be described by the equation W * 4W = 324. This equation can be expanded to 4W^2 = 324.

To find the width of the rectangle, we can take the square root of both sides of this equation, which gives W^2 = 81. Taking the square root of 81 gives W = 9 feet, which is the width of the rectangle.

Since the length of the rectangle is 4 times the width, the length of the rectangle is 4 * 9 = 36 feet. So the dimensions of the rectangle are 9 feet by 36 feet.

This means that if you draw a rectangle with a width of 9 feet and a length of 36 feet, the area of this rectangle would be 324 square feet.

The correct option is option(a) as only one letter is required to name a point.

What is a point?

A point in traditional Euclidean geometry is a simple concept that represents an exact place in space and has no length, breadth, or thickness. A point in modern mathematics is more broadly referred to as a component of a set known as a space. A point is an area that is depicted by a dot. A point just has a position; it lacks any dimensions such as length, width, shape, or size.

Usually, a geometrical figure is named by assigning one letter to each vertex of the figure.

So for a rectangle, it is 4 letters.

Hexagon is named using 6 letters since it has 6 vertices.

For a point, as mentioned there are no dimensions. It is just a dot.

Therefore a point is named using only one letter.

4 < x < 6: decreasing.

6 < x < 8: increasing.

8 < x < 10: decreasing.

10 < x < 14: neither increasing or decreasing.

A relationship between a group of inputs and one output is referred to as a function. In plain English, a function is an association between inputs in which each input is connected to precisely one output. A domain, codomain, or range exists for every function. Typically, f(x), where x is the input, is used to represent a function.

First, we need to know when the function is increasing, and when is decreasing.

It is because greater x-values correspond to higher y-values that a function increases. On the other side, a function decrements when lower y-values are associated with greater x-values. The function will move in the graph in an upward direction when it is rising and in a downward direction when it is decreasing.

So, according to the given graph, we see that between 0 and 4 is increasing, the higher x-values are, higher y-values are. Between 4 and 6 is decreasing, is downwards. Between 6 and 8 is increasing. Between 8 and 10 is decreasing. In finally, between 10 and 14 is neither decreasing or increasing, it remains horizontal.

All these interpretations we can expressed using math language, specifically inequalities:

0 < x < 4: increasing.

4 < x < 6: decreasing.

6 < x < 8: increasing.

8 < x < 10: decreasing.

Complete question:

Answer:

$23.13

Step-by-step explanation:

The subtotal of the books before the discount is $25. To calculate the value, you multiply $25 by 12% (0.12), which equals $3. So the total cost of the books after the discount is $25 - $3 = $22.

Next, to calculate the cost of the books, including the state sales tax, you would multiply $22 by 7.5% (0.075), which equals $1.65.

Therefore, the total cost of the books, including the state sales tax is $22 + $1.65 = $23.65

The f(8) of the exponential function is 131072

The general form of the exponential function is f(x) = abˣ

First, derive the function using the table. That is:

From the table, when x = 0, f(x) = 2. Substitute the values into the function:

f(x) = abˣ

2 = ab⁰             (Note: b⁰ = 1)

2 = a(1)

2 = a

a = 2

Also, from the table, when x = 3, f(x) = 128. Substitute the values into the function:

128 = 2 × b³

128 = 2b³

64 = b³

b³ = 64

b = ∛64

b = 4

We can now write the exponential function for the data:

f(x) = abˣ

f(x) = 2(4)ˣ

Thus, f(8) = 2(4)⁸ = 131072

Answer: Without more information about the outstanding balance on your mortgage and the exact terms of the new mortgage, it is not possible to determine the answer to your question. The amount of the monthly payments and the total amount of interest paid over the life of the loan will depend on these factors. But here a way you can do it.

Step-by-step explanation:

First, determine the outstanding balance on the original mortgage by calculating the total payments made over the past five years and subtracting them from the original loan amount. To do this, multiply the monthly payment amount by the number of months in five years (60) to find the total payments made.

Next, calculate the new monthly payment amount on the refinance mortgage by using a mortgage calculator or the formula: M = P[r(1+r)^n]/[(1+r)^n-1], where M is the monthly payment, P is the outstanding balance from step 1, r is the interest rate (0.06625), and n is the number of payments (360 for a 30-year mortgage).

Compare the new monthly payment amount to the original monthly payment amount to see how much you will save or pay more each month.

Consider any fees or closing costs associated with refinancing and factor those into the decision to refinance.

If the savings from the lower interest rate outweigh the costs of refinancing, it may be a good decision to move forward with the refinance.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

Area of the rectangle is 63 ft².

The length of a rectangle is 11 ft more than double the width.

let the width be x.

So, the length is 2x + 11.

So, Area of rectangle = 63 ft².

l x  w = 63

(2x+ 11) x = 63

2x² + 11x = 63

2x² + 11x - 63 =0

Answer:

sinB= 3.8(sin16/2.4) or ~0.45162

[Note: ~ means about]

Step-by-step explanation:

To solve this problem, we need to use the Law of Sines. The Law Of Sines states that sinA/a = sinB/b. Since we know the value of A,a, and b, we can plug our known values in to find our unknown value, sinB.

sinA/a = sinB/b   [Plug in known values]

sin16/2.4 = sinB/3.8

Now, we want to just find the value of sinB. To do this, we will need to multiply both sides by 3.8, so the right side just reads sinB.

sin16/2.4 = sinB/3.8   [Multiply by 3.8]

3.8(sin16/2.4) = sinB

Now, if we want the exact answer, we can leave it as is. If you are looking for a decimal answer, let's continue to see what we would get:

3.8(sin16/2.4) = sinB

3.8(0.27563/2.4) ~ sinB

  A = (√a +√b +√c)²

Step-by-step explanation:

Given triangle ABC has interior point O that defined three similar triangles whose bases are the sides of triangle ABC and whose sides are lines through O parallel to the other two sides, and that those similar triangles have areas of 'a', 'b', and 'c', you want the area of ∆ABC in terms of 'a', 'b', and 'c'.

Let a reference to "triangle x" be a reference to "the triangle whose area is x", where x ∈ {a, b, c}. Let kx represent the ratio of the height of triangle x to the height of ∆ABC from the same base. If A is the area of ∆ABC, then ...

The nature of point O is such that ka +kb +kc = 1.

This means ...

  √(a/A) +√(b/A) +√(c/A) = 1

  √a +√b +√c = √A . . . . . . . . . . multiply by √A

  A = (√a +√b +√c)² . . . . . . . . . . square both sides

The value of B on the table is given as follows:

D. 90.

A proportional relationship is defined as follows:

y = kx.

In which k is the constant of proportionality.

From the table, the constant is obtained as follows:

k = 20/14 = 40/28 = 10/7.

Hence the relationship is given as follows:

y = 10x/7.

The value of B is the value of y when x = 63, hence:

y = 10 x 63/7

y = 10 x 9

y = 90.

Step-by-step explanation:

You want an algebraic solution to the system of equations ...

The second equation suggests an expression for x:

  x = 2y -5z +3

Substituting this into the first and third equations, we have ...

  2(2y -5z +3) +3y -4z = -1   ⇒   7y -14z = -7   ⇒   y -2z = -1

  -4(2y -5z +3) +y +z = 16   ⇒   -7y +21z = 28   ⇒   y -3z = -4

These equations are reduced to standard form by dividing by the leading coefficient.

Subtracting the second of these equations from the first, we have ...

  (y -2z) -(y -3z) = (-1) -(-4)

  z = 3 . . . . . . . simplify

The first of these reduced equations tells us ...

  y = 2z -1 = 2(3) -1 = 5

  x = 2y -5z +3 = 2(5) -5(3) +3 = -2

The solution is (x, y, z) = (-2, 5, 3).
