Oliver draws a line on his paper and from a point on the line draws a circle. he then measures the radius of his circle and constructs an arc inside his circle from a point on the circle. what is he trying to construct?
a) a square inscribed in a circle
b) a trapezoid inscribe in a circle
c) a pentagon inscribed in a circle
d) an equilateral triangle inscribed in a circle

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
