By factor decomposition and algebra properties we conclude that the fraction 42 / 49 is equivalent to the fraction 6 / 7.

<h3>Which pair of fractions is equivalent to each other?</h3>

According to the statement, we have the equation of a fraction and we need to find the expression by simplify the former expression. In this situation we must use factor decomposition and algebra properties to make simplification effective:

<h3></h3>

42 / 49                           Given

(2 × 3 × 7) / (7 × 7)          Factor decomposition

(2 × 3) / 7 × (7 / 7)           Commutative and associative properties / Multiplication of fractions

6 / 7 × 1                           Definition of division / Existence of the multiplicative inverse

6 / 7                                 Modulative property / Result

By factor decomposition and algebra properties we conclude that the fraction 42 / 49 is equivalent to the fraction 6 / 7.

F(x)=x^2-3x-2 is shifted 4 units left. The result is g(x) what is g(x)
grandymaker [24]

To solve this problem you must apply the proccedure shown below:

1. If the function f(x)=x^{2}-3x-2 is shifted 4 units left, this means that you must substitute the value of x by x+4 to find g(x), as following:

f(x+4)=(x+4)^{2}-3(x+4)-2

2. Now, expand the function:

f(x+4)=x^{2} +8x+16-3x-12-2\\ f(x+4)=x^{2} +5x+2

3. Then, you have that g(x) is:

g(x)=x^{2} +5x+2

Therefore, the answer is: g(x)=x^{2} +5x+2

If AD = 5.1cm, find the height (in cm) of the triangle.
Irina-Kira [14]

Answer:

I. AC = 15 cm

II. h = 7.4 cm

Step-by-step explanation:

I. Determination of AC

AB = 9 cm

BC = 12 cm

AC =?

The length AC can be obtained by using pythagoras theory as illustrated below:

AC² = AB² + BC²

AC² = 9² + 12²

AC² = 81 + 144

AC² = 225

Take the square root of both side

AC = √225

AC = 15 cm

II. Determination of the height.

AB = 9 cm

AD = 5.1 cm

BD = h =?

The height of the triangle can be obtained by using pythagoras theory as illustrated below:

AB² = AD² + BD²

9² = 5.1² + h²

81 = 26.01 + h²

Collect like terms

h² = 81 – 26.01

h² = 54.99

Take the square root of

h = √54.99

h = 7.4 cm

How do you solve<br><br> sin9x/1-cos^2(9x)
Anuta_ua [19.1K]
Using formula sin^2 x +cos^2 x = 1 you get 1 - cos^2(9x) = sin^2(9x)

so in this way this fraction will be rewrited 

sin9x/(1-cos^2(9x) = sin9x / sin^2(9x) = 1/sin9x
