The graph below shows the solution to which system of inequalities?

B

Step-by-step explanation:

first there have a full line that means y must be > and = one figure

B) y ≥ 2 and y < x

Step-by-step explanation:

The horizontal line on the graph is at y = 2.  Since the shaded portion is above the line, this makes it greater than.  Since the line is solid, this makes it greater than or equal to.  This gives us y ≥ 2.  This makes B the only choice.

5 seconds

1220 ft

Step-by-step explanation:

Step 1: Know when the stone reaches the maximum height

We know the maximum or minimum height of a parabola is at the vertex so we need to find the vertex

Step 2: Calculate the vertex

The t coordinate of the vertex can be calculated with

b = 160

a = 16

Step 3: We know the t coordinate we can find the height at that time

Therefore the stone reaches its maximum height of 1220 ft in 5 secs
