Let sintheta =2times square root 3/5 and pi/2

Gre4nikov [31]

Given:

$sin\theta=\frac{2\sqrt{3}}{5},\text{ and }\frac{\pi}{2}$

It's required to find cos 2θ.

We use the formula:

$cos(2\theta)=1-2sin^2\theta$

Substituting:

$cos(2\theta)=1-2(\frac{2\sqrt{3}}{5})^2$

Operating:

$\begin{gathered} cos(2\theta)=1-2*\frac{4*3}{25} \\ cos(2\theta)=1-\frac{24}{25} \\ cos(2\theta)=\frac{1}{25} \end{gathered}$

Answer: 1/25

Slope = 4, passing through (-3,4)<br> Type the point-slope form of the equation of the line.

natta225 [31]

Answer:

y - 4 = 4 (x + 3)

Step-by-step explanation:

Point-slope form is y - y1 = m (x - x1)

y1 is 4, m is 4, and x1 is -3

When you plug them in, you get: y - 4 = 4 (x + 3)

Note: (x - -3) becomes (x + 3)

I hope this helps!!
