The distance between the building and the base of the ladder is 4 feet.

The trigonometric functions are functions that can be applied to determined the side or measure of internal angle of a given triangle. Given that some required properties are given.

Given that the ladder is 8 feet long, let the distance between the building and the base of ladder be represented by t.

So that;

Cos θ = adjacent/ hypotenuse

Cos 60 = x/ 8

x = 8*Cos 60

  = 8*0.5

x = 4

Thus, the building is 4 feet far to the base of the ladder.

The polynomial function is obtained to be h(x) = -2 (x - 4)(x - 1)²(x + 2), with the values a = -2, b = -4, c = -1 and d = 2.

What is a polynomial?

An algebraic expression known as a polynomial requires that all of its exponents be whole numbers. Any polynomial must have variable exponents that are non-negative integers. Although a polynomial contains variables and constants, we are unable to divide a polynomial by a variable.

The characteristics of the polynomial are -

The zeros are located at 4, 1 (multiplicity of 2) and-2

The end behavior is as follows -

As x reaches negative infinity, f(x) reaches negative infinity.

As x reaches infinity, f(x) reaches negative infinity.

The y-intercept of the function is (0, 16)

The equation of h(x) can be written as -

h(x) = a(x+b)(x+c)²(x+d)

The zeroes of the polynomial can be written as -

x = 4 ⇒ (x - 4)

x = 1 ⇒ (x - 1)

x = 1 ⇒ (x - 1)....Since the multiplicity is 2 so write it two times.

x = -2 ⇒ (x + 2)

So, the equation will be -

y = a (x - 4)(x - 1)(x - 1)(x + 2)

The y-intercept is given as (0,16).

So, substitute the values of x and y with 0 and 16 respectively.

y = a (x - 4)(x - 1)(x - 1)(x + 2)

16 = a (0 - 4)(0 - 1)(0 - 1)(0 + 2)

16 = 2a(-4)(-1)(-1)

16 = 2a × -4

16 = -8a

a = -2

Hence, the equation becomes y = -2 (x - 4)(x - 1)(x - 1)(x + 2).

On graphing the equation it can be seen that -

As x → -∞, f(x) x → -∞

As x x → ∞, f(x) x → -∞

Therefore, the polynomial equation is h(x) = -2 (x - 4)(x - 1)²(x + 2).

To determine the amount of work done by the person in the wheelchair going up the ramp, you can use the formula for work:

work = force x distance x cos(theta)

where force is the force exerted by the person (25 N), distance is the distance traveled (10 m), and theta is the angle between the force and the displacement.

The angle between the force and the displacement is 90 degrees because the force is perpendicular to the displacement.

The force exerted by the person is to overcome the force of gravity on the person and wheelchair weight (60 N).

work = force x distance x cos(90)

work = (25 N + 60 N) x 10 m x cos(90)

work = 85 N x 10 m x 0

work = 0 J

It's impossible to do work when the angle between the force and the displacement is 90 degrees because the force and the displacement are perpendicular to each other.

The height of the ramp (3 m) is not used in this calculation, as it is not related to the force or distance.

The work done by the person in the wheelchair is 0 J because the force exerted by the person is perpendicular to the displacement. However, the person will be expending energy to overcome the force of gravity and move the wheelchair up the ramp.

The amount of yard that has to be given to Laura is c) 500 m2

They are the set of numbers and symbols that are related by the different mathematical operation signs such as addition, subtraction, multiplication, division among others.

To solve this problem we must perform the following algebraic operations with the given information:

Total of money = 540 000

Laura's money = 300 000

Lets represent the amount of money Laura gave:

Laura's % = (300 000 / 540 000) * 100

Laura's % = 30/54 * 100

Laura's % = 5/9 * 100

Laura's % = 55.56%

The amount of yard should be for Laura is:

The nature of the roots of the quadratic equation 9x2 12x + 4 is that it has one root, which is equal to -4.

The nature of the roots of a quadratic equation is determined by its discriminant (b2 – 4ac). The discriminant of the given equation 9x2 12x + 4 is (12)2 – 4(9)(4) = 144 – 144 = 0.

Since the discriminant is equal to zero, the equation has two equal (or identical) roots. This indicates that the equation has one root since its roots are equal. We may apply the quadratic formula to get the equation's root.

The quadratic formula states that the roots of a quadratic equation can be found by solving the equation:

x = (-b ± √(b2 – 4ac))/2a

When we apply the formula to the given equation, we get:

x= (-12 ± √(0))/2(9)

Since the discriminant is equal to zero, the equation has one root. The root of the equation is x = -4.

Factor the radicand: If the radicand is not already in the form of a perfect square, you can factor it into its prime factors and pull out any perfect squares from the radicand.

For example, √(36) can be simplified to √(49) = √4 * √9 = 23.

Simplify the exponent: If the radical has an exponent (such as cube root), divide the exponent by the index of the radical. Example ∛64 = ∛(4^3) = ∛4 * ∛4 * ∛4 = 4 *4 *4 =4

Combine like factors: If there are any factors in the radicand that match the exponent, you can combine them and simplify the radical further. For example, √(2235) = √(2^235) = 2√(35) = 2√15 = 2*3 = 6.

Three points can define the two distinct vectors AB and AC (A, B, and C). The two vectors' cross product, which they both lie on, may be utilized as the plane's normal.

It is logical to assume that this is the case since a plane contains precisely two linearly independent vectors since it has a dimension of two. If the three points were collinear, there wouldn't be two linearly independent vectors; instead, the origin and tips of the two vectors are the three points.

The three points that make up a plane in a three-dimensional space can be used to define it as long as they are not on the same line. On a plane, there exist at least three non-collinear points.

A 30-60-90 triangle is a special type of right triangle that has specific angle measurements: one angle is 90 degrees (the right angle), one angle is 30 degrees, and one angle is 60 degrees. The ratio of the sides in a 30-60-90 triangle is also fixed, the longest side is opposite the 90-degree angle and it is always twice the length of the shortest side and the medium side is opposite the angle of 60 degrees and it's always the square root of 3 times the length of the shortest side.

For example, if a right triangle has angles of 45 degrees, 45 degrees, and 90 degrees, it is not a 30-60-90 triangle. The angles do not fit the pattern of 30-60-90 degrees.

Therefore, In short, all 30-60-90 triangles are right triangles, but not all right triangles are 30-60-90 triangles. A 30-60-90 triangle is a special type of right triangle with specific angle measurements and side ratios.

First, solve the equation for one of the variables in the pair of equations to be solved using substitution method x = 2/13, y = 52

The substitution method is one algebraic approach to solving a linear system. By substituting one y-value for another, the substitution method works. We will illustrate this with an example. Since y = y, we can use y in the first equation instead of the second one.

                                      4x+2y=10⋅2x=26+2y

Take the first equation, for example. For a result of 20, multiply 10 by 2.

                                     4x+2y=20x

20 x both sides should be subtracted.

                                    4x+2y−20x=0

Get 16x by combining 4x and 20x.

                                  −16x+2y=0

The second equation is an example. For a result of 20, multiply 10 by 2.

                                      20x=26+2y

From both sides, subtract 2y.

                                          20x−2y=26

First, solve the equation for one of the variables in the pair of equations to be solved using substitution. Replacing that variable in the other equation with the result follows.

                                       −16x+2y=0,   20x−2y=26

By placing x on the left side of the equal sign, isolate x from one of the equations and solve it for x.

                                                −16x+2y=0

In the equation, deduct 2y from both sides.

                                     −16x=−2y

Subtract 16 from both sides.

                                          x= − 16/ 1(−2)y

16 divided by 2y is the answer.

                                         x= 8  / 1 y

The second equation, 20x2y=26, should now read 8 y instead of x.

                                  20×( 8 /1  )y−2y=26

multiply 20 times 8 y.

                          2  / 5 ​ y−2y=26

Boost 2y by 2.5 years.

                                 2 /1  y=26

2 times both sides will give you y=52.

In the formula x = 81y, change y to 52. You can solve for x directly because the resulting equation only has one variable.

                                        x= 8 /1  ×52

52 x 8 /1 is the multiplication.
