A medicine is applied to a burn on a patient's arm. The area of the burn in square centimeters decreases exponentially ad is shown in the graph.

A. What fraction of the burn area remains each week?

B. Write an equation representing the area of the burn ,a, after t weeks

C. what is the area of the burn after 7 weeks? round to three decimal places

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .

answer: both chords and diameters have two endpoints on a circle. diameters must intersect the center of a circle.

it would rotate about 180 degrees.
