Research and write about the history of pi and its importance to the study of geometry. a small prompt

here is the

mark brainliest pl

step-by-step explanation:

a'(12.5,11.25)

slope=(y1-y2)/(x1-x2)

why are you giving so many marks make your marks less and make a question list so that i can understand your question very nicely

h is the x-coordinate of the vertex

step-by-step explanation:

we have

in this function

the point represent the vertex of the function

so

h is the x-coordinate of the vertex

k is the y-coordinate of the vertex
