The person will have to place the compasses 6 feet away from the point they want the arch to start, and draw the arch with a radius of 9 feet.

The radius of the arch is 9 feet.

The formula for calculating the radius of an arch is [tex]R = (width / 2) / sin(90°)[/tex].

Therefore, the radius of the arch is:

R = (18 ft / 2) / sin(90°) = 9 ft

To calculate the radius of the arch he needs to draw, the person can use the formula R = (width / 2) / sin(90°). In this case, the width of the arch is 18 feet, so the radius of the arch is 9 feet, calculated as R = (18 ft / 2) / sin(90°). The person will have to place the compasses 6 feet away from the point they want the arch to start, and draw the arch with a radius of 9 feet.

This is consistent with the solutions for the equation x2 - 6x + 5 = 0 being x = 1 and x = 5.

An equation is a mathematical statement that expresses the equality of two expressions. It consists of one or more terms, each of which contains one or more variables. The terms are separated by an equal sign (=) and are usually written in a standard form known as an algebraic equation. Equations can be used to model and solve problems in a wide variety of fields, from physics and chemistry to economics and finance.

The graph of the quadratic equation is a parabola that opens upward and intersects the x-axis at two points. The x-intercepts occur when the equation is equal to zero, so the x-intercepts for the equation x2 - 6x + 5 = 0 are the solutions for x. These solutions are x = 1 and x = 5.

The graph of the quadratic equation also shows that the two solutions of the equation, x = 1 and x = 5, are the x-intercepts of the parabola. This means that when x equals 1 or 5, the equation is equal to zero, so the x-intercepts are the solutions of the equation. This is consistent with the solutions for the equation x2 - 6x + 5 = 0 being x = 1 and x = 5.

So Francessa used 8 cups of flour

Answer:

36

Step-by-step explanation:

An arithmetic sequence is a sequence of numbers in which the difference between any two consecutive terms is constant. A geometric sequence is a sequence of numbers in which any two consecutive terms have a constant ratio.

Given that 8, 2x, 2y is an arithmetic sequence, we know that:

2x - 8 = 2y - 2x

x = y

Given that 2x, 2y, 36 is a geometric sequence, we know that:

(2y)/(2x) = 36/2y

y^2 = 36x

Now, we can use the first equation to substitute for y in the second equation, and get:

x^2 = 36x

x^2 - 36x = 0

x(x-36) = 0

So x = 0 or x = 36

However, x cannot be equal to zero because in that case the second term of the arithmetic sequence will be zero, and it will not be a valid solution. Therefore, x = 36.

So, y = x = 36.

Therefore, the values of x and y are 36.

The equation of the plane passing through (0, -3,1) that is orthogonal to the planes 3x + 2y - 4z = 0 and - X+ 2y + 4z = 7 is 16x - 8y + 8z = 32

We know that the equation of plane passing through point (x₁, y₁, z₁) is given by,

A(x - x₁) + B(y - y₁) + C(z - z₁) = 0

where, A, B, and C are direction ratios

In the question,  the plane passes through point (0, -3,1)

Let (x₁, y₁, z₁)  = (0, -3,1)

Using above formula the equation of the plane will be in the form,

A(x -0) + B(y - (-3))+C(z - 1) = 0            

Ax + B(y + 3)+C(z - 1) = 0                   ..........(1)

The required plane is orthogonal to the planes 3x + 2y - 4z = 0 and - X+ 2y + 4z = 7.

So, their normal to the required plane would be perpendicular to the normal of both the planes.

The normal to the required plane is a cross-product of the normals of planes.

A cross-product of the normals of planes 3x + 2y - 4z = 0 and - X+ 2y + 4z = 7 is 16i - 8j + 8k

So, the direction ratios,

A = 16, B = -8, C = 8

So equation (1) becomes,

16x - 8(y + 3) + 8(z - 1) = 0  

16x - 8y - 24 + 8z - 8 = 0

16x - 8y + 8z - 32 = 0 is the required equation of the plane

Answer: To find the average of daily income of the week, we need to find the total income of the week and divide it by the number of days in the week.

We know that the average daily income of the week is Rs 1,300 and we know that he earned Rs 2,000 on Saturday. To find the total income for the week, we can add the Saturday income to the average daily income for the 6 days.

Therefore, the total income for the week = Rs 1,300 (average daily income) x 6 (days) + Rs 2,000 (Saturday income) = Rs 7,800 + Rs 2,000 = Rs 9,800

To find the average daily income for the week, we divide the total income by the number of days in the week (7)

Average daily income = Rs 9,800 / 7 = Rs 1,400

Therefore, the average daily income of the plumber for the week is Rs 1,400.

We can conclude that (1-sinx)(1+cscx)=cscx-sinx is a true equation.

An equation is a mathematical expression containing symbols, constants, and/or numbers that combine to create an equation that states the equality of two mathematical expressions. Equations are used to describe relationships between different quantities and can be used to model real-world phenomena. Equations can also be used to solve problems and make predictions about a system.

To verify that this equation is true, we can use algebraic manipulation. First, we need to expand the left side of the equation. We can do this by multiplying (1-sinx) by (1+cscx). This gives us the equation (1-sinx)(1+cscx) = 1+cscx-sinx-sinxcscx.
Next, we need to simplify the right side of the equation. We can do this by combining the two terms with a minus sign. This gives us cscx-sinx.
Finally, we can compare the two equations. We see that both equations are equal, so the original equation is true.
Therefore, we can conclude that (1-sinx)(1+cscx)=cscx-sinx is a true equation.

The answer is The graph does not represent a one-to-one function because the y-values between 0 and 2 are paired with multiple x-values.​

What is the one-to-one function?

The one-to-one function is a special function that maps every element of the range to exactly one element of its domain i.e, the outputs never repeat. As an example, the function g(x) = x - 4 is a one-to-one function since it produces a different answer for every input.

To be a function, it has to pass the vertical line test, which means a vertical line drawn anywhere in the graph should cut the graph only once, not more.

To be a one-to-one function, it has to pass the vertical line test as well as the horizontal line test, which means that a horizontal line drawn anywhere in the graph should cut the graph only once, not more.

Of course, it passes the vertical line test, so it's a function.

Does it pass the horizontal line test? NO! As shown in the attached picture, the blue line (horizontal line) cuts the graph at 3 places.

We, therefore eliminate choices A and B.

We can eliminate choice C because nowhere is it requires a function to pass through the origin for it to be one-to-one.
