The actual length of the house is 30 feet.

What is a scale factor?

A scale factor resembles a unit scale in several ways. It is a ratio that assesses the relationship between scale and real dimensions. Because it doesn't provide any specified units, it differs.

It is given that:

Width of the kitchen = 4 inches.

Length of the kitchen= 6 inches.

It is also given that the actual width of the house is equal to 20 feet.

Now we have to find the length of the house:

The proportion will be:

[tex]\frac{4}{6} =\frac{20}{Length} \\Length=\frac{20*6}{4} \\Length=30feet[/tex]

Therefore the actual length of the house is 30 feet.

Answer:

If the ratio of the length to width of the rectangle is 3 to 2, we can write the length and width as:

length = 3x and width = 2x

where x is a common factor that can be determined once we know one of the dimensions.

Since the length of the rectangle is given as 1 3/4 feet, we can set x = 1 3/4:

length = 3x = 3 * 1 3/4 = 5 1/4 feet

width = 2x = 2 * 1 3/4 = 3 1/2 feet

Now that we know the length and width of the rectangle, we can calculate its area in square inches:

area = length * width = 5 1/4 * 3 1/2 = 18 3/8 square feet

To convert from square feet to square inches, we multiply by 12^2 = 144:

area = 18 3/8 * 144 = 2664 square inches

So the area of the rectangle is 2664 square inches.

The value of x at the point of intersection is given as follows:

x = -1.

We must test for both definitions of the second function, and find which solution is in the correct range.

For the first definition, the solution is given as follows:

2x + 1 = x

2x - x = -1

x = -1.

-1 is less than 1, hence x = -1 is one solution to the system of equations.

For the second definition, the solution is given as follows:

2x + 1 = -x + 2

3x = 1.

x = 1/3.

Which is less than one, while the function is defined for values greater than 1, hence it is an extraneous solution.

Answer:

  45°

Step-by-step explanation:

Given a polygon with an interior angle of 135°, you want to know the measure of the corresponding exterior angle.

At any given vertex of a polygon, the interior and exterior angles are supplementary:

  exterior angle = 180° - interior angle

  exterior angle = 180° -135°

  exterior angle = 45°

Answer: The sum of the interior angles of a regular polygon can be found using the formula:

(n-2)180°, where n is the number of sides of the polygon.

Let's call the number of sides of the polygon "s".

We know that one of the interior angles is 135°, so we can set up an equation using the formula for the sum of the interior angles:

s * 135° = (s-2)180°

Expanding the right side of the equation:

s * 135° = (s-2) * 180°

s * 135° = s * 180° - 360°

Solving for s:

135° = 180° - 360°/s

135° = 180° - 2 * 180°/s

135° = 180° - 2 * (180°/s)

180° - 135° = 2 * (180°/s)

45° = (180°/s)

So, s = 180° / 45° = 4 sides.

The size of one exterior angle can be found by subtracting each interior angle from 360°:

360° - 135° = 225°.

Therefore, one exterior angle of the polygon is 225°.

Step-by-step explanation:

Answer: A tangent to the x-axis means that the y-coordinate of the point of tangency is 0. So, we can find the possible values of d by setting y = 0 and solving for x:

0 = x^3/3 + 7x^2/2 + 10x + d

This is a cubic equation, so it can be solved using various methods such as factoring, completing the square, or using a numerical method such as the Newton-Raphson method. If the equation can be factored or the method used is numerical, there might be multiple possible values of d. If the method used is completing the square, there would be only one possible value of d.

However, without a specific method, it's not possible to find the exact value(s) of d. The possible values of d will depend on the specific solution method used to solve the equation.

We use particular terminology to define the sides of right triangles. A right triangle's hypotenuse is always side opposite the right angle.

When one of a triangle's angles is exactly 90 degrees, the triangle is said to be right-angled. The remaining two angles together equal 90 degrees..

Answer: To verify the identity, we need to convert both sides into sines and cosines and see if they are equal.

Starting with the left side:

cotx = 1/tanx

So,

cotx - tanx = 1/tanx - tanx

Using the identity tan^2x = sec^2x - 1, we get

cotx - tanx = (sec^2x - 1) / tanx

Expanding the right side using the definition of cscx and sinx, we get:

cotx - tanx = secx(1/sinx - 2sinx)

So,

cotx - tanx = secx(cscx - 2sinx)

Since both sides are equal, we can conclude that the identity is verified.

Answer:

Step-by-step explanation:

The floor-to-ceiling clearance is 7 ft 5 in, which is equal to 7 * 12 + 5 = 89 inches.

We need to construct 8 shelves, each of which is 1 inch thick, so the total thickness of the shelves is 8 * 1 = 8 inches.

We also need to leave an equal space between each shelf and the next, the top shelf and the ceiling, and the bottom shelf and the floor. So, there will be 7 equal spaces in total (6 between shelves and 1 between the bottom shelf and the floor).

Therefore, the space between each shelf and the next will be (89 - 8) / 7 = 11 inches.

Here's a step by step solution:

Calculate the total height of the room in inches: 7 ft 5 in = 7 * 12 + 5 = 89 inches.

Calculate the total thickness of all the shelves: 8 shelves * 1 inch/shelf = 8 inches.

Deduct the thickness of the shelves from the height of the room to find the total space available: 89 inches - 8 inches = 81 inches.

Divide the total space available by the number of spaces (7) to find the space between each shelf and the next: 81 inches / 7 = 11 inches.

The balance in the account after 1 year due to continuous compounding is approximately $1030.45 and AYP is 3.04%.

What is meant by continuous compounding?

If compound interest is calculated and reinvested into the balance of an account across an essentially unlimited number of periods, continuous compounding is the mathematical limit that compound interest can reach. Continuous compounding determines interest by assuming constant compounding across an infinite number of periods, as opposed to computing interest on a finite number of periods, such as annually or monthly.

Given,

rate per period  = 3%

Principal amount = $1000

Compounding is done after 1,5 and 20 years.

But we are asked to find the amount after continuous compounding after 1 year.

The formula of the amount after continuous compounding is:

[tex]A = Pe^{rt}[/tex]

where A = amount after continuous compounding

        r = rate of period

     t = time period

    P  = principal amount

[tex]A = Pe^{rt} = 1000e^{0.03*1}[/tex] = $1030.45

Annual yield formula (AYP) = [tex](1+\frac{r}{n} )^n-1[/tex]

n = times it compounds per year = 365

r = 0.03

AYP = [tex](1+\frac{0.03}{365} )^{365}-1 = 0.0304[/tex]

                                  = 3.04%

The g-intercept of the function g(n) is 0.

The n-intercepts of the function g(n) are n = 0, n = -3, and n = -7.

What is a function?

In mathematics, a function is a relation between a set of inputs (the domain) and a set of possible outputs (the range), such that each input is related to exactly one output.

To find the g-intercept of a function, we need to determine the value of g when n = 0. So, to find the g-intercept of the function g(n) = 2n⁴+ 20 n³ + 42n², we can simply substitute n = 0 into the function:

g(0) = 2(0)⁴ + 20 (0)³ + 42(0)² = 0

Therefore, the g-intercept of the function g(n) is 0.

To find the n-intercepts of a function, we need to determine the values of n for which g(n) = 0. In other words, we need to solve the equation 2n⁴+ 20 n³ + 42n² = 0.

We can factor out a common factor of 2n² to simplify the equation:

2n²(n² + 10n + 21) = 0

This equation is true when either 2n² = 0 (which implies n = 0), or when n² + 10n + 21 = 0. The quadratic equation n² + 10n + 21 = 0 can be factored as (n + 3)(n + 7) = 0, so its solutions are n = -3 and n = -7.

The n-intercepts of the function g(n) are n = 0, n = -3, and n = -7.

Hence,

The g-intercept of the function g(n) is 0.
