Referring to triangle ABC, find the area of the triangle.

kondaur [170]

Answer:

$Area = 337$

Step-by-step explanation:

Given

$a = 42.5$

$c = 35.5$

$B = 153.5^\circ$

Required

Area of triangle

This is calculated as:

$Area = 0.5 *a* c * \sin(B)$

This gives:

$Area = 0.5 *42.5* 35.5 * \sin(153.5)$

$Area = 0.5 *42.5* 35.5 * 0.4462$

$Area = 336.602125$

$Area = 337$ --- approximated

Multiply the denominator to 100

5. 1/10 = 10/100 which equals to 10%

6. 2/25 = 8/100 which equals to 8%

7. 27/50 = 54/100 which equals to 54%

Find the Inverse Function : Algebra 2 y = 2x² + 1

Vera_Pavlovna [14]

$\displaystyle\\Answer:\ y=\sqrt{\frac{x-1}{2} } \ \ \ \ (x\geq 1,\ \ \ \ y\geq 0)$

Step-by-step explanation:

$y=2x^2+1\\$

We change the argument and the value:

$\displaystyle\\x=2y^2+1\\\\x-1=2y^2+1-1\\\\x-1=2y^2\\$

Divide both parts of the equation by 2:

$\displaystyle\\\frac{x-1}{2}=y^2\\\\ \sqrt{\frac{x-1}{2} }=y \ -\ the\ desired\ inverse\ function\\\\$

The restrictions are imposed on the inverse function by on x:

$x-1\geq 0\\x\geq 1$

The restrictions are imposed on the inverse function by on y:

$y\geq 0$

Then the original function is defined on the sets:

$x\geq 1,\ \ \ \ y\geq 0$

The initial function, a parabola, is constrained because of the inverse function; only in this case the functions are reciprocal.
