Answer:

y = 2x+8

Step-by-Step Explanation:

The equation should be in the form of y=mx+b

So you already know it's not A. Also you already know it's not D because the line goes at an angle, if "m"(slope) was 0 then the line would be straight horizontal or straight vertical. So that leaves B and C. And finally you know it's not B because the line is going in the positive direction not negative, so the slope has to be positive, also "b" in the equation is the y-intercept, and that's where the line intersects with the y-axis, and you can see that the line intersects at 8 on the graph. Therefore, the answer is C, y=2x+8

Hope this helps!! :)

Answer:

The area of the semi circle $A = 157.1 cm^2$

Step-by-step explanation:

<u><em>Explanation</em></u>:-

<em>Given radius of circle 'r' = 10 cm</em>

<em>The area of the circle formula </em>

<em> </em> $A = \pi (r)^{2}$ <em></em>

<em>The area of the semi circle formula </em>

$A = \frac{\pi (r)^{2} }{2}$

taking π =3.142

$A = 3.142 X \frac{(10)^2}{2}$

On calculation , we get

$A = 157.1 cm^2$

<u><em>Final answer</em></u>:-

<em>The area of the semi circle </em> $A = 157.1 cm^2$ <em></em>
