A pattern is made from four congruent squares. The sides of the squares are parallel to the axes Point A has coordinates (3,2) Point B has coordinates (27,30) Point C is marked on the diagram Work out the coordinates of C. Apologies, I couldn't get the full image of the graph​

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).

step-by-step explanation:

x^2 + 81

we can factor this using difference of square binomials.

rewrite the equation:

x^2 - (-81)

factor:

(a^2 - b^2) = (√a^2 + √b^2)(√a^2 - √b^2)

(x^2 - (-81) = (x + √-81)(x - √-81)

we can remove the - from under the radical by multiplying it by i.

(x^2 - (-81) = (x + i√81)(x - i√81)

(x^2 - (-81) = (x + 9i)(x - 9i)

we can check our answer by using foil:

x^2 - 9ix + 9ix - 81i^2

x^2 - 81^2

i^2 = -1

x^2 + 81

parallel lines have the same slope. so if the green line has a slope of -4, the slope of the red line is also -4.
