Write an equation (-2, 10), (10, -14)

Brilliant_brown [7]

$\bf (\stackrel{x_1}{-2}~,~\stackrel{y_1}{10})\qquad (\stackrel{x_2}{10}~,~\stackrel{y_2}{-14}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{-14}-\stackrel{y1}{10}}}{\underset{run} {\underset{x_2}{10}-\underset{x_1}{(-2)}}}\implies \cfrac{-24}{10+2}\implies \cfrac{-24}{12}\implies -2$

$\bf \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{10}=\stackrel{m}{-2}[x-\stackrel{x_1}{(-2)}]\implies y-10=-2(x+2) \\\\\\ y-10=-2x-4\implies y=-2x+6$

The measure of angle θ is 600°. <br> The point (x, y) corresponding to θ on the unit circle is (

Grace [21]

On the unit circle the hypotenuse is always one so we can say:

sinα=y/1 and cosα=x/1 so

The point corresponding the the angle 600° is:

(cos600, sin600) which is approximately

(-1/2, -√(3/4)

I WILL NAME BRAINLIEST FOR WHOEVER CAN WRITE THE ANSWER! I WILL NOT GIVE IT ANYONE WHO JUST POINTS! What is the area of the figu

PtichkaEL [24]

Answer:

$48.5cm^{2}$

Step-by-step explanation:

This shape is actually just a rectangle with a missing triangle. We can first find the area of the rectangle with $7*8=56$ and subtract the triangle.

Area of missing triangle = $\frac{1}{2} *b*h$ (b is the base and h is the height)

Base = $8-3=5$

Height = $7-4=3$

Area of missing triangle = $\frac{1}{2} *5*3=7.5$

Area of the figure: $56-7.5=48.5$

--------------------------------------------------------------------------

Alternatively, you can find the area of each individual shape and add them all up.

Area of the rectangle: $8*4=32$

Area of square: $(7-4)*3=9$

Area of triangle: $\frac{1}{2} *(8-3)*(7-4)=\frac{1}{2} *5*3=7.5$

Total Area: $32+9+7.5=48.5$
