The x-intercept is (-4/3,0).
Hope that helps!
Step-by-step explanation:
Area is 12*5=60
Height is 4
Perimeter is 2*17=34
Surface area=120+136=256
1st disribute .4 through the parentheses.
.4 (.3x-1)=2+.75x
.12x-.4=2+.75x
subtract .12x from each side
-.4 = 2 + .63x
subtract 2 from each side
-2.4 = .63x
Divide each side by .63
-3.81 = x
Since they give you the graph find the highest point in the curved line:
the line touches the number 100
so it's maximum height is 100 feet
now from where it touches 100 look at the time:
it hits 100 feet at 2.5 seconds
