Pictured below are two semicircles. AB is tangent to the smaller semicircle and is parallel to CD. It is known that
AB = 28 cm. If the area of the shaded region is ka cm²,
find the exact value of the constant k.

answer: do we write it

step-by-step explanation:

answer: idk

step-by-step explanation:

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9

tried on you are knowing that we can't leave the picture in the graph ok no problem now you need to send it in the question group
