A decagon is a shape with 10 sides and 10 vertices
Answer:it might be D
Step-by-step explanation:
You just need to solve for x in the equation:
–0.01x^2 + 0.32x + 4 = <span>–0.01x^2 + 0.18x + 5
0.18x=1
x= 5.55
h(5.55) = -0.01*30.86+0.18*5.55+5 = -0.3086+1+5=5.6914
The intersection point is (5.55, 5.69).
I hope that this is the answer that you were looking for and it has helped you.

( - 10, - 22 )
using the midpoint formula,
let the other endpoint have coordinates (x, y) then
(2 + x ) = - 4 ( multiply through by 2 )
2 + x = - 8 ( subtract 2 from both sides ) then
x = -8 - 2 = - 10 ← value of x-coordinate
Similarly for y-coordinate
(8 + y ) = - 7 ( multiply through by 2 )
8 + y = - 14 ( subtract 8 from both sides )
y = - 14 - 8 = - 22 ← y -coordinate
the other endpoint is ( - 10, - 22 )
