Carla was provided the quadratic equation y=(x−2)(x+4), which models the height (in meters) of a rollercoaster over time (in seconds). In this context, what does the x-2 tell Carla about the rollercoaster's path? A) The ride will reach a minimum height of 2 meters below ground.
B) The ride will cross ground level after 2 seconds.
C) The ride will reach a minimum height of 2 meters above ground.
D) The ride will reach its minimum height after 2 seconds.

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204

step-by-step explanation:

a cube has 6 sides

the probability of getting 5 on the first cube is 1/6 since only one side of the cube has 5 on it.

there are 3 sides of the cube with even number on it [2,4,6]

therefore the probability of getting even number is 3/6

for both events to happen together, the probability would be

1/6 x 3/6 = 12/36

which simplifies to 1/12
