The function h(t) = –16t2 + 28t + 500 represents the height of a rock t seconds after it is propelled by a slingshot. What does h(3. 2) represent? the height of the rock 3. 2 seconds before it reaches the ground the time it takes the rock to reach the ground, or 3. 2 seconds the time it takes the rock to reach a height of 3. 2 meters the height of the rock 3. 2 seconds after it is propelled.

Layer r contains a well-known index fossil that is 100 million years old. based on this information and the principle of superposition, a. layers t and m are older than 100 million years, and layers x and g are younger than 100 million years. b. layers t, m, x, and g are all older than 100 million years. c. layers t and m are younger than 100 million years, and layers x and g are older than 100 million years.
