A swimmer dives off the edge of a cliff. The distance, d(t), in meters, the swimmer travels after
t seconds can be modeled by the function d(t)=0.5t^2. What is the average speed, in meters
per second, of the rock between 3 and 8 seconds after she dived? *

answer: y = -2.5x - 15

              (-6,0)

step-by-step explanation:

answer: i dont know but if you try hard you will get it right : )

step-by-step explanation:

18 units²

step-by-step explanation:

first let's find altitude bd using the distance formula

d = √((y₂ - y₁)² + (x₂ - x₁)²)

bd = √((0 - -3)² + (0 - 3)²)

bd = √18

given the placement of points a and c, we can denote that point d bisects segment ac.

we will call ac the base.

using the distance formula

ac = √((0 - 6)² + (-6 - 0)²)

ac = √72

knowing our base and our height, we can plug these into our triangle area formula

area = (b * h)/2

area = (√18 * √72) / 2

area = (√1296) / 2

area = 36 / 2

area = 18 units²
