Answer:

The slope will be 1/2.

Step-by-step explanation:

Sine the lines are perpendicular, the slope of the green line will be the negative reciprocal of the slope of the red line. To find the negative reciprocal of -2, first change the sign. Since the slope is negative, make it positive 2. Then to find it's reciprocal, divide 1 by your answer. 1 divided by 2 is one half, s that is your answer.

HELP! A semi circle of radius 6 is centered at the origin as shown. A rectangle has two of its vertices at (5,0) and (-5,0) and

Ugo [173]

The Area of rectangle is " $30 \ unit^2$ " and the equation of the semi circle is " $y = \sqrt{36-x^2}$ ".

According to the question,

The vertices of rectangle,

(5, 0) and (-5, 0)

Length,

l = 10 unit

Breadth,

b = 3 unit

Radius of semi circle,

r = 6

Centre of origin,

(0, 0)

As we know,

→ The Area of rectangle is:

= $Length\times Breadth$

= $10\times 3$

= $30 \ unit^2$

and,

→ The Equation of semi circle is,

$y = \sqrt{r^2-x^2}$

by substituting the values, we get

$=\sqrt{(6)^2-x^2}$

$= \sqrt{36-x^2}$

Thus the above is the correct answers.
