A rock is thrown upward from the top of a cliff. The expression 16x2 + 25x + 800 describes the rock's height from the base of the cliff, in feet, x seconds after it is thrown. What does the
constant term represent?
o The rock takes 800 seconds to hit the ground.
•The maximum height of the rock is 800 feet above the base of the cliff.
•The rock falls at a speed of 800 feet per second.
• The height of the cliff is 800 feet.

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.

2nd one in the first row is correct

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
