The circumference of a circle is pi(d). Since the bottom half of the shape is a semicircle, we know the radius is 9 and the diameter 18. So, the circumference (aka perimeter) of that semicircle would be (3.14x18)/2. Then add 5+5+12in.

Answer:

50.26 units.

Step-by-step explanation:

Perimeter of the given picture = perimeter of trapezoid with 3 sides + perimeter of semicircle.

Perimeter of trapezoid = 12 + 5 + 5

                                      = 17 + 5

                                      = 22

Perimeter of semicircle = π r

                                      = π × 9

                                      = 3.19 × 9

                                      = 28.26

Now perimeter of the figure = 28.26 + 22

                                              = 50.26 units.

Which choice is the equation of the line that passes through the point (5, 19) and has a slope of
Liono4ka [1.6K]

Answer:

The equation is;

y = 12x-41

Step-by-step explanation:

Mathematically;

slope intercept form is;

y = mx + b

where m is slope and b is intercept

Since we already have the slope , the equation is;

y = 12x + b

To get b which is the y intercept, we simply substitute the value of the points given

Thus;

19 = 5(12) + b

19 = 60+ b

b = 19-60

b = -41

So the equation is;

y = 12x - 41
