Answer:

length of x is 8

Step-by-step explanation:

According to trigonometry:

Side opposite to given 45° is x and hypotenuse is 8√2

Sinθ = opposite side / hypotenuse

Sin45° = x/ 8√2

1/√2 = x /8√2

x = 8√2 / √2

x = 8

Which system of equations can be used to find the roots of the equation 12 x 3-5x=2 x 2+x+6

kirill [66]

Answer:

Option (a) is correct.

The system of equation becomes

$y=12x^3-5x\\\\ y=2x^2+x+6$

Step-by-step explanation:

Given : Equation $12x^3-5x=2x^2+x+6$

We have to construct a system of equations that can be used to find the roots of the equation $12x^3-5x=2x^2+x+6$

Consider the given equation $12x^3-5x=2x^2+x+6$

To construct a system of equation put both sides of the given equation equal to a same variable.

Let the variable be "y", Then the equation $12x^3-5x=2x^2+x+6$

becomes,

$12x^3-5x=y=2x^2+x+6$

Thus, The system of equation becomes

$y=12x^3-5x\\\\ y=2x^2+x+6$

Option (a) is correct.

Is (-2,2) a solution to the inequality <br>y>1/2x-2<br><br><br>yes or no

densk [106]

Answer: Yes it is a solution

Work Shown:

Replace x with -2, replace y with 2. Simplify.

y > (1/2)x - 2

2 > (1/2)*(-2) - 2

2 > -1 - 2

2 > -3

The last inequality is true, so the original inequality is true when (x,y) = (-2,2)

This makes (-2,2) a solution to the inequality.
