The method we need to use here is very particular to this type of a situation.  The way we will find that polynomial, or the divisor, is to follow this formula:  g(x)= \frac{dividend-remainder}{quotient}.  For us that will look like this:   g(x)= \frac{4x^4-5x^3-39x^2-46x-2-(-5x+8)}{x^2-3x-5}.  First we will simplify as much as possible that very long numerator there.  It simplifies to   g(x)= \frac{4x^4-5x^3-39x^2-41x-10}{x^2-3x-5}.  What you do now is use long division of polynomials, which, unfortunately, is impossible to show in this forum.  However, get familiar with the long division process if you are not already, and you will find that your polynomial g(x) is   4x^2+7x+2.

A hydrogen atom is about 5×10 to the -11 power
Olegator [25]

Factors are numbers that can be multiplied by an integer to obtain the desired integer

The size of the human hair is <u>1.0 × 10⁻⁴ meters </u>

Reason:

The given parameters are;

The size of an hydrogen atom is 5 × 10⁻¹¹   meters

The width of the human hair is 6 times as big

Therefore, we have;

The width of the human hair is 2 × 10⁶ times as big, therefore, we have;

The size of the human hair = 5× 10⁻¹¹ × 2 × 10⁶ = 1.0 × 10⁻⁴

The size of the human hair is <u>1.0 × 10⁻⁴ meters</u>

The length of one side of a triangle is 2 feet less than three times the length of its second side. The length of the third side
Zanzabum

Using a system of equations, it is found that the lengths of the sides of the triangle are given as follows:

0.91 feet, 0.73 feet, 1.23 feet.

<h3>What is a system of equations?</h3>

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the variables are the lengths, given by x, y and z.

The length of one side of a triangle is 2 feet less than three times the length of its second side, hence:

y = 3x - 2.

The length of the third side is 3/4 of the sum of the lengths of the first two sides, hence:

z = \frac{3(x + y)}{4} = \frac{3(4x - 2)}{4}

The perimeter of the triangle is 17.5 feet, hence:

x + y + z = 17.5

x + 3x - 2 + \frac{3(4x - 2)}{4} = 17.5

4x + \frac{3(4x - 2)}{4} = 19.5

16x + 12x = 25.5

x = 25.5/28

x = 0.91.

Then the other sides are:

  • y = 3x - 2 = 3(0.91) - 2 = 0.73 feet.
  • z = \frac{3(4 x 0.91 - 2)}{4} = 1.23 feet

zubka84 [21]

Answer:

C.

Step-by-step explanation:

I believe the answer is C.

Secant is just 1/cos

In that case,

sec∅ = 5/3 = cos∅ = 3/5
