The pencil was reduced by 1/6 of its original length. Hence, the correct option is Option C.

To calculate the fraction, you must divide the remaining length (15 cm) by the original length (18 cm). In order to get a fraction, you have to divide it by their highest common factor, which in this case is 3.

= \frac{15}{18}

= \frac{5}{6}

This is the length of the pencil left at the end of the day. To find the fraction used, you have to subtract this fraction from its whole.

= 1 - \frac{5}{6}

= \frac{5}{6} - \frac{5}{6}

= \frac{6-5}{6}

The distance of a = 1 / 2 pi, b = 1 pi, and c = 3 / 2 pi.

The complete movement of an object, regardless of direction, is referred to as distance. The amount of ground a thing travels from its starting point to its destination is also referred to as distance.

Given:

The time, t = π / 2 sec,

Calculate the distance by using the formula given below,

[tex]Distance = r\times time[/tex]

So, for distance, a = 1 × π / 2 =  π / 2

for distance, b = 1 × π =  π

Using the square formula, the value of (1+i)^4 is -4.

The square formula is the algebraic identity which is used to find the square or difference of the sum of two terms. The square of sum of the two terms and can be calculated by multiplying the binomial by itself. The general form of square formula to find the square of the sum of two terms is given by: (a + b)^2 = a^2 + 2ab + b^2 where a and b are variables.

The given expression can be rewritten as binomial with exponent:

((1 + i)^2)^2

Using the square formula to find the square of the sum of two terms to the (1 + i)^2. Hence,

(1 + i)^2 = 1 + 2i + i^2

As 'i' iota is the square root of negative 1, i^2 = -1

1 + 2i -1 = 2i

Therefore,

(2i)^2 = 4i^2 = 4*-1 = -4

Answer:

To prove the given identity, we can start by multiplying both sides of the equation by (cosθ - sinθ) to obtain:

(cosθ/1 - tanθ) (cosθ - sinθ) - sin^2θ/(cosθ - sinθ) = (cosθ + sinθ)(cosθ - sinθ)

Expanding both sides of the equation gives us:

cos^2θ - tanθcosθ - sin^2θ = -sin^2θ + cos^2θ

We can simplify this equation to:

-tanθcosθ = -sin^2θ + cos^2θ

We can simplify this further by using the identity cos^2θ + sin^2θ = 1:

-tanθcosθ = 1 - 2sin^2θ

We can rearrange this equation to solve for sin^2θ:

sin^2θ = (1 + tanθcosθ)/2

This is the desired result, so we have successfully proved the given identity.

The expressions have, the first expression has degree 5, end behavior to ± infinite terms , zeros are h = 0, -1/2 , -1/2, 11 , 11 and 2 multiplicity -1/2 and 11 and sketch is drawn in image 1. And second expression has degree 4, end behavior to + infinite terms , zeros are x = 0,0, 3,-3. , 2 multiplicity of 0 and sketch is drawn in image 2.

An expression that consists of variables, constants, and exponents that is combined using mathematical operations like addition, subtraction, multiplication, and division is referred to as a polynomial.

Given that the expression ;

T(h) = h (2h + 1)²(h - 11)² and D(x) = 3x⁴ - 27x²

Now for the first expression T(h) = h (2h + 1)²(h - 11)²

Simplifying, the expression;

T(h) = h (2h + 1)²(h - 11)²

Degree of the highest polynomial of above expression is 5.

To find end behavior, we will find the factors of expression;

T(h) = h (2h + 1)²(h - 11)²

Here, h = 0,  (2h + 1)² = 0 , (h - 11)²= 0

h= 0 , h = -1/2 , -1/2 and h = 11 , 11

Multiplicity of -1/2 is 2 and 11 is 2.

End behavior, given expression has 2 pair of repeated roots.

And  (2h + 1)² ≥ 0 , (h - 11)²≥ 0

So the expression behavior depends on the term h alone.

And also it is an even polynomial.

So the graph of expression varies to infinity term for both positive and negative.

Zeros of the polynomial are  h = 0, -1/2 , -1/2, 11 , 11.

Sketch 1,

Now for the second expression D(x) = 3x⁴ - 27x²

Simplifying, the expression;

D(x) = 3x⁴ - 27x²

Degree of the highest polynomial of above expression is 4.

To find end behavior, we will find the factors of expression;

D(x) =3x²(x+3)(x−3)

Here, x = 0,0, 3,-3.

Multiplicity of 0 is 2.

End behavior, it is an odd polynomial. So the graph of expression varies to positive infinity.

Sketch 2,

Therefore, the first expression has degree 5, end behavior to ± infinite terms , zeros are h = 0, -1/2 , -1/2, 11 , 11 and 2 multiplicity -1/2 and 11 and sketch is drawn in image 1. And second expression has degree 4, end behavior to + infinite terms , zeros are x = 0,0, 3,-3. , 2 multiplicity of 0 and sketch is drawn in image 2.

The plane with an angle of depression of 70° is closer to the airport.

The distance between the plane and the airport is 15957 feet.

There are three commonly used trigonometric identities.

Sin x = 1/ cosec x

Cos x = 1/ sec x

Tan x = 1/ cot x or sin x / cos x

Cot x = cos x / sin x

We have,

Two planes are flying at an altitude of 15,000 feet.

The angle of depression from one plane to the airport is 70°.

This means,

The distance of the plane from the airport.

Sin 70 = 15,000 / Distance

Distance = 15,000/ sin 70 = 15,000 / 0.94 = 15957 feet _____(1)

The angle of depression from one plane to the airport is 60°.

The line given by the point slope equation y - 8 = 1/2 (x - 4) represents the linear function f(x) = [tex]\frac{1}{2}[/tex] x + 6.

Linear functions are those functions whose graph drawn is a straight line. It consists of one dependent variable and one independent variable.

Linear functions are usually represented as f(x) = y = p + qx.

The given equation of the line in point slope form is,

y - 8 = 1/2 (x - 4)

⇒ y - 8 = (1/2 × x) - (1/2 × 4)

⇒ y - 8 = 1/2x - 2

⇒ y = 1/2x -2 + 8

⇒ y = 1/2x + 6

When x = 0, y = f(0) = (1/2 × 0) + 6 ⇒ f(0) = 6
