An architect decides to use a parabolic arch for the main entrance of a science museum. in one of his plans, the top edge of the arch is described by the graph of y = -1/4x^2 + 5/2x + 15. what are the coordinates of the vertex of the parabola?

just take the area of the square and then the area of the circle then subtract the circle area from the squares area

step-by-step explanation:

r = 78539458390583095803458309458039485093485 or just 3

step-by-step explanation:

answer:  

step-by-step explanation:

odd numbers are only divisible by 1 and itself.

even numbers are divisible by more than 1 and itself.

for example 6 is even because it is divisible by more than 1 and its self. 1 x 6= 6 ; 2 x 3= 6

and 7 is odd because only 7 x 1 equals seveb

see below

step-by-step explanation:

x+2> 6

subtract 2 from each side

x+2-2 > 6-2

x > 4

there is an open circle at 4 since is it is greater than and the line goes to the right
