An equation of a line through (2, 4) which is perpendicular to the line y = -2x + 1 has slope:
and y-intercept at:

slope: 1/2. y-int: 3

Step-by-step explanation:

for slope: the slope for a perpendicular line is the negative reciprocal. so -2 flipped is -1/2 and adding on a negative will cancel the original one so 1/2.

for y int: use the new slope and the point given to figure it out.

4 = 1/2(2) + b --> 4 = 1 +b --> b = 3

answer

a the answer hopes this

step-by-step explanation:

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.
