Answer:

Using SohCahToa we know it will be opposite over adjacent, opposite being the side across from theta and adjacent being the side next to theta, Using Toa we know it will be opposite over adjacent so the answer will be 6/2sqrt5

If they wants you to simplify more than you cant have a sqrt on the bottom so to fix this you will multiply the top and bottom by sqrt5 leaving you with 6sqrt5/ 2*5 or 6sqrt5/15

hope this helped

CAN SOMEONE PLEASE ANSWER THE FOLLOWING IT URGENT

Answer:

See bolded below.

Step-by-step explanation:

As you said, you only need help with no. 2:

a) Check the attachments for the lines

b) The equations are, respectively:

y = -4x + 1 [intersects parabola at 1 point]

Check:

$\begin{bmatrix}y=\left(x-2\right)^2-3\\ y=-4x+1\end{bmatrix}$

$\begin{bmatrix}-4x+1=\left(x-2\right)^2-3\end{bmatrix}$

$\begin{bmatrix}-4x+1=x^2-4x+1\end{bmatrix}$

$x^2=0, x = 0$

$y=-4\cdot \:0+1 = 1$

$y=1,\:x=0$

The point of intersection would be (0, 1)

y = -4x + 3 [intersects parabola at 2 points]

Check:

$\begin{bmatrix}y=\left(x-2\right)^2-3\\ y=-4x+3\end{bmatrix}$

Subtract the 2 equations,

$y=\left(x-2\right)^2-3\\-\\\underline{y=-4x+3}\\y-y=\left(x-2\right)^2-3-\left(-4x+3\right),\\0=x^2-2\\x = \sqrt{2}, x = - \sqrt{2} \\\\\mathrm{Plug\:the\:solutions\:}x=\sqrt{2},\:x=-\sqrt{2}\mathrm{\:into\:}y=\left(x-2\right)^2-3$
