Completing the square is done as follows:<span>

1. Write the equation in a way that the constants are in the right side while the terms with x are on the left. 
</span>x^2 – 6x = 5<span>

2. Make sure that the coefficient of the x^2 term is 1.
</span>x^2 – 6x = 5<span>

3. Adding a term to both sides that will complete the square in the left side. This is done by dividing the coefficient of the x term by 2 and squaring it. Note: The same amount should be added to the right side to balance the equation.
</span>x^2 – 6x + 9 = 5 + 9<span>

(x-3)^2 = 14

Therefore, 9 should be added to both sides to complete the square.</span>

If tan x° = 6 divided by g and sin x° = 6 divided by h, what is the value of cos x°? cos x° = h divided by g cos x° = g divided
Westkost [7]

The value of cos x⁰ from the information given is; g/h.

<h3>What is the value of cos x⁰?</h3>

According to the task content;

  • The value of cos x° from the information contained in the task content is required.

From conventional Trigonometry;

  • It follows that tan x = sin x/cos x.

On this note, it follows that;

cos x⁰ = sin x⁰/tan x⁰.

cos x⁰ = 6/h ÷ 6/g

cos x⁰ = g/h

Ultimately, the value of Cos x⁰ by evaluation is g/h.

A japanese beetle has a length between 0.3 and 0.5 inch.find two lengths that are within the given span.express them as a fracti
DanielleElmas [232]
Hello,

One method of finding a value in between two other numbers is taking the average, it will always be between the numbers. To find the average of two numbers, add the numbers and divide it by how many numbers there are. 

In this case, we have:
(0.3) + (0.5) /2 = 0.8 / 2 = 0.4

So, 0.4 is one length that is within the given span.
Another example is 0.45, which is also between 0.3 and 0.5.

0.4 represented as a fraction is 4/10. However, this can be simplified (notice 4 and 10 are both divisible by 2). To simplify this fraction, divide the numerator and denominator of the fraction by 2 to get (4/2) / (10/2) = 2/5.

0.45 represented as a fraction is 45/100. This fraction can also be simplified (notice 45 and 100 are both divisible by 5). To simplify this fraction, divide the numerator and denominator of the fraction by 5 to get (45/5) / (100/5) = 9/20.

Two lengths that are within the span are 2/5 inches and 9/20 inches, both of which are in simplest form.

Hope this helps!
