What is the solution for the system of equations? 2y=4x-12 and y=-2x+2

1 answer:

6 0

$2y = 4x - 12 \\ y = - 2x + 2 \\ \\ 2( - 2x + 2) = 4x - 12 \\ - 4x + 4 = 4x - 12 \\ 4 = 8x - 12 \\ 16 = 8x \\ 2 = x \\ \\ y = - 2(2) + 2 \\ y = - 4 + 2 \\ y = - 2$

Which is equivalent sin^-1 (cos(pi/2))?Give your answer in radians

NNADVOKAT [17]

Answer:

Given the expression: $\sin^{-1}(\cos(\frac{\pi}{2}))$

Let the value of the given expression in radians be $\theta$

then;

$\sin^{-1}(\cos(\frac{\pi}{2})) =\theta$

$\cos \frac{\pi}{2} = \sin \theta$ ......[1]

We know the value of $\cos \frac{\pi}{2} = 0$

Substitute the given value in [1] we have;

$\sin \theta = 0$

Since, the value of $\sin \theta$ is 0, therefore, the value of $\theta$ is in the form of:

$\theta = n\pi$ ; where n is the integer.

At n =0, 1 and 2, {Since, n is the integer}

Value of $\theta =0, \pi$ and $2\pi$

therefore, the answer in radians either $0 , \pi$ or $2\pi$
