Answer:

Step-by-step explanation:

(B) The is answer is q^18

q*q*q*q*q*q*q*q*q = q^9

Then

q^9^2 = 9*2 = q^18

If sin x = 12÷13 where 0° &lt;x&lt;90°<br>find the value of 1-cos ×cos( x)​
s2008m [1.1K]

Answer:

This is how tackle this type of problem:

Draw a right triangle with the indicated sides: side opposite the angle = 12 and hypotenuse = 13

Then, calculate the 3rd side by Pythagoras: x2 + 122 = 132

x2 = 169 - 144

x2 = 25

x = 5

Now, we have all 3 sides of our diagram triangle, so we can find all the trig ratios for the angle.

Next, we use the double angle formula to simplify cos(x + 30) = cos x cos 30 - sin x sin 30

= 5/13 . √3/2 - 12/13 . 1/2

= 5√3 /26 - 6/13

= (5√3 - 12) / 26

Two fractions have denominators of x^2+ 6x + 9 and x^2. What is the Least Common Denominator?
Gala2k [10]

SOLUTION

Write out the denominator of the fraction, we have

\begin{gathered} x^2+6x+9 \\ \text{And } \\ x^2-9 \end{gathered}

We want to obtain the least common denominator.

To do this, we need to factorize each of the expression given

\begin{gathered} x^2+6x+9 \\ =x^2+3x+3x+9 \\ =x(x+3)+3(x+3) \\ =(x+3)(x+3) \end{gathered}

Then we factorise the other fraction using difference of two square

\begin{gathered} a^2-b^2=(a-b)(a+) \\ \text{Then} \\ x^2-9=x^2-3^2 \\ =(x-3)(x+3) \end{gathered}

The the factorise expression becomes

(x+3)(x+3)\text{ and (x-3)(x+3)}

To obtain the least common denominator, we select the common factor and the product of the other factor,

Hence

\begin{gathered} \text{common factor=(x+3)} \\ \text{The other factors are (x-3)(x+3)} \\ \text{Then } \\ \text{Least co}mmon\text{ denominator becomes } \\ (x+3)(x-3)(x+3) \end{gathered}

Thus

The Least Common Denominator is (x +3)(x+3)(x-3) (Last Option )
