Answer:
x = -3
Step-by-step explanation:
The solution to the equation ...
f(x) = g(x)
is the x-value where the functions have equal values. That is the x-coordinate of the point where the graphs intersect. The intersection point is (-3, 5), so the solution to the equation is x = -3.
-16t^2 + 1000 > 300
16t^2 < 1000 - 300
16t^2 < 700
t^2 < 700/16
t^2 < 43.75
t < 6.61
B, D, E. Rectangle and polygon are 2 dimensional and its obviously not a pyramid.
