Which of the following represnt the range of the function y=-1/2(x+10)^2+14?
1) y> =-5 2)y> =10 3) y< =7 4) y< =14, explain pls

the second one

Step-by-step explanation:

cuz i say so

4). But the more correct answer is; y is less than or equal to 14.

Step-by-step explanation:

Graphing this function shows a downward facing parabola with the vertex at (-10,14).  The domain must be less than or equal to 14 because it's all values including and below the vertex since there is negative a value (-1/2).

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
