The midpoint of (x1,y1) and (x2,y2) is

just average them
(4,1) and (-2,4)
the midpoint is

(1,-1.5)
The answer is D) 3,404
By putting the table values into the progam DESMOS, and then putting in the formula, the answer will be given- and that answer is 3,404.
Answer:
downwards
Step-by-step explanation:
the equation of a parabola in vertex form is
f(x) = a(x - h)² + k
where (h, k ) are the coordinates of the vertex and a is a multiplier
• if a > 0 then parabola opens upwards
• if a < 0 then parabola opens downwards
for
f(x) = - 4(x - 3)² + 9 with a = - 4 < 0 , then
the parabola opens downwards
Answer: 3,2.50)
Step-by-step explanation:
2x + x = 24
so x = 24/3 = 8 ft. (smaller length)
2x = 16 ft. (larger length)
